Furthermore, students will evaluate whether dominant or recessive genes are more impacted by these environmental changes. Students must have prior knowledge of Punnett squares.
This module is a hands-on simulation of how DNA ultimately creates the proteins in our bodies. Students are provided with DNA gene sequences, which they must first transcribe into mRNA and then translate into a protein (amino acid sequence) to build a new species, called the Scimon. Time permitting, students may have the opportunity to investigate the effects of three types of mutations (insertion, deletion and substitution) on their Scimon model.

If time allows, older classes may discuss the concept of herd immunity.
After reviewing lab safety and introducing the dissection procedure, students dissect a preserved frog in order to observe the external and internal structures of frog anatomy.
This lesson’s multiple short activities will walk students through their eyes from front to back, experimenting with and experiencing how different parts affect image formation. Students observe the contraction of the iris, the minimum focal length of the lens, the distribution of rod and cone cells in the retina and the effect of this distribution on peripheral vision, the blind spot resulting from the existence of the optic disk, and optionally, the function of the cone cells. This lesson, though fun as a stand-alone, is designed to coordinate with the AP14 Eye Dissection module. It is intended to enhance students’ appreciation of the structures they will observe in the dissection of the sheep eye, by allowing them to first observe the functions of those structures in their own eyes.
This lesson engages students by asking them to compare a camera with a mammalian eye. Then, after reviewing lab safety, the instructor briefly introduces the dissection procedure and students work in pairs to explore the anatomy of a preserved sheep eye. The lesson ends with a review of mammalian eye anatomy and the basic mechanics of vision.
After reviewing lab safety, the instructor will provide students with an orientation of the heart’s surface features and identification of key structures and vessels.

After a brief introduction to the structure and functions of the mammalian brain, students examine preserved sheep brains and make observations about the external and internal anatomy.
This lesson is an introduction to the human nervous system (NS), and focuses on the human brain and its functional units, the neurons. The neuron is the basic working unit of the NS: it is a specialized cell designed to transmit information to other nerve cells. The activity in this lesson allows younger students to explore the structure and function of the brain and neurons through the construction of models. Older (6th-8th grade) students will construct models, as well as learn about nerve cell communication.
The human brain is highly adaptable system. This activity demonstrates how the brain learns to adapt to an altered situation. Students divide into small groups and learn to toss beanbags at a target while wearing prism goggles. They then remove the goggles and “unlearn” the task. Students collect data from these experiments and interpret it in the context of their brain’s adaption and subsequent communication with sensory and motor systems.
This module teaches methods for analyzing different hair samples. It begins by discussing what hair is and why it is important in nature and in forensics.

In this lesson, students will be introduced to the Arrhenius theory of acids and bases (acids dissociate into H+ and bases into OH-). They will learn that pH gives us a measure of the concentration of H+ in solution, and they will use a universal indicator and pH strips to test the pH of various common household liquids. Note: The background information provided by this lesson is largely the same as the background info in C06: Acid-Base Titration, but the activity in this lesson aimed at 4th- 6th grade students.
In this lesson, students will be introduced to the Brønsted-Lowry theory of acids and bases (acids donate a H+ ion and bases accept the H+ ion). They will perform a simple titration to neutralize a base with an acid, using a color indicator to determine the endpoint. This lesson is intended for older (7th & 8th grade) students.
The lesson begins with a review of atoms, elements, and a discussion of organic versus inorganic compounds. Students learn that organic compounds, such as sugars, starches, and proteins, can be identified with the use of chemical indicators, which produce a characteristic color when a particular substance is present. Using these chemical indicators, students test a variety of food samples for the presence of proteins, and simple and complex carbohydrates. Fats (lipids) are identified by their ability to make paper translucent. This lesson is geared towards older (6th-8th grade) students.
Students are introduced to the technique of chromatography as a way to separate compounds. In the activity, students will test four different inks to separate on a strip of chromatography paper and compare to an unknown brand of ink. While the experiment is running, the students will participate in a discussion and demonstration of how chromatography works. After the chromatographs have developed, students will identify the unknown ink by comparing the chromatographs to the known ink.
This lesson provides an exploration in electrophoresis using wet and dry activities. The wet activity is to run an agarose gel electrophoresis, which is typically done to separate macromolecules (such as DNA) in a laboratory setting. The dry activities are designed to convey the concept that migration of molecules during electrophoresis is size-dependent, and to have students predict the results of their agarose gel electrophoresis. This lesson is geared towards older (8th grade) students. It is recommended to conduct this lesson in classes at least 60 minutes long.

Students will be introduced to the problem—damage due to seismic waves—and will build and test different block configurations to determine which model provides the best solution.
This lesson provides students with a deeper understanding of the issues that surround an oil spill and highlights methods of environmental clean-up. Using a model of an oil spill in an “ocean”, students act as environmental engineers to test different methods for effectively cleaning up the spill, and determine the harmful effects that oil spills and their clean-up have on animals and the environment.
This lesson is an introduction to basic plate tectonics. It includes a review of the earth’s internal structure and the formation of continents, oceans, and mountain ranges as a result of plate movement. There will be a discussion of the mechanism of earthquake production as the sudden release of rock under stress.

The students will hypothesize about how actual geologic formations were made and will test their hypotheses using sponge and clay models of faults. This lesson is geared for students in grades 4-6.
This lesson reviews and expands on the basics of map literacy. In particular, it familiarizes students with topographic maps – a type of map that describes the physical features of an area of land. In the activity, all students will create a 3D model of a landform and then use it to create a 2D topographic map. Lengthy classes and older students (6th-8th) will also use a topographic map to create a 3D model.
In this team problem-solving exploration, an astronaut crew has suffered an emergency crash landing on the Moon 60 miles from their destination. Everything is damaged except for 14 specific items. Each student must decide which items are most useful, based on their knowledge of their Moon and resources available. Individuals then come together in teams to share ideas and negotiate team choices as they rank the salvaged items in terms of their importance in allowing them to reach their base. At the conclusion, item scores can be compared to real NASA scientist rankings.
Celestial mechanics deals with the movement or motions of celestial objects (objects found in space). In this lesson, students learn about the moon’s orbit around earth, and how the moon progresses through its eight major phases and why Earthlings have only ever seen one side of the moon! Older students and longer classes will also be able to explore solar and lunar eclipses.
This lesson provides an overview of the objects that make up our solar system, with an emphasis on modeling the scale of both the sizes of objects and distances between them. Students will challenge their assumptions about the scale of our Solar System by building models in order to begin to visualize how much of space is really just… vast, empty space. They will use two separate models, evaluating the strengths and weaknesses of each.
This lesson provides an overview of the Rock Cycle, highlighting common rocks and the processes that form them. The three rock types found on Earth (igneous, sedimentary and metamorphic) are discussed and their specific characteristics are described. Students will examine rock samples, note similarities, classify them by rock type, and identify them.

This lesson is geared towards older (6th – 8th grade) students.
This module introduces how water cycles through different forms and storage types on Earth and in Earth’s atmosphere. Students hypothesize about the path water takes through the water cycle. Each student will act as a water molecule and move around the room to model the path that a water droplet might take. The class will then identify benefits and limitations of this water cycle model.
Plants get much of what they need from sunlight, air, and water, but they also need nutrients that come from the soil. In this lesson, students perform tests of the concentrations of the soil nutrients nitrogen, phosphorus, and potassium (NPK), and, time allowing, a test of soil pH. The activity is a multistep process that allows students to practice measuring, following directions, and evaluating their results by comparing to a standard. Both tests use commercially-available kits, and students may bring in their own soil samples to test.
This lesson introduces students to the characteristics and formation of soil. In order to answer the question of which soil is best for a tomato plant, students examine the color, texture, and field capacity (a measure of how much water soil can hold and make available to plants) of different soils.
This lesson is an introduction to the concept that S- and P-waves travel at different speeds away from the epicenter of an earthquake, and explains how we can take advantage of this fact in order to locate the epicenter. After a brief review of basic earthquake plate tectonics, S- and P-waves will be defined and explained with a demonstration using multiple Slinky toys. Students will then be challenged to locate the epicenter of an earthquake by using data from the timing of S- and P-waves to triangulate on a map.

The lesson utilizes demonstrations and videos to explore how the Earth’s human population has grown and how limited our resources are. Then students (unsuspectingly) explore the concept of the Tragedy of the Commons through a group ‘fishing’ activity, culminating in a discussion of the Tragedy of the Commons and how we can stop or prevent them.
Students learn about the relationship between nutrition and fresh/processed foods, then verify this information by measuring the concentration of vitamin C in different forms of orange juice.
Students work in pairs to model photosynthesis through an interactive game. From their game evidence, students then develop an argument that plants need sunlight, carbon dioxide, and water to make food.
Students will use a dichotomous key to identify trees by their leaves. Students will learn the vocabulary necessary to describe the leaves in order to identify the trees from which they came. Students will also compare conifers and broadleaf trees, discuss the function of the leaf, and talk about the advantages of each type of leaf.
This module allows students to become more aware of what they eat and why as we explore a variety of food additives prevalent in the modern diet of processed foods and how they are used.

Due to the timing constraints of the experiment, this module requires a minimum 60-minute class. This lesson is geared towards older (7th-8th grade) students.
Camouflage and mimicry are explored as examples of animal adaptations that increase chances of survival. Students play a hunting game to gain an appreciation of the problems that these adaptations pose for predators. Classes with more time can continue to explore different examples of camouflage and mimicry.
This module explores the mechanisms by which biodiversity (genetic variation) is created within populations. It explains the concepts of mutation, gene flow, genetic drift, and natural selection, and how these mechanisms work in different ways to create genetic variation in a population. In the activity, students will use beads and event cards to simulate how a population of beetles changes over time. This lesson is intended for older (6th-8th grade) students. Students should be familiar with DNA, genes, and heritable traits before this lesson is taught.
In this introduction to electrical conductors and insulators, students are challenged to build a simple circuit, test and classify various materials as conductors or insulators, and add a switch to the circuit.

This module is a qualitative introduction to projectile motion. Students first independently compare the paths followed by objects simply dropped from a height (that is, having zero horizontal velocity) with those of objects pushed off an elevated surface (with nonzero horizontal velocity). Student observations are used as a segue into an explanation of velocity as a quantity that has both size and direction, and which can be understood in terms of its horizontal and vertical components. The lesson concludes with an activity testing the horizontal range of a projectile as a function of its launch angle. Students will make a graph of the range vs. launch angle and will discover the angle at which a projectile travels the furthest horizontal distance after launching. This lesson is aimed at older (7th-8th grade) students.
There are two types of electricity: current and static. This lesson focuses on static electricity, which is a charge separation (buildup of an electric charge) on the surface of an object. This is different from current electricity, which is the flow of electrons. During the activity, students will assemble an electroscope, an instrument used to detect the presence and magnitude of an electric charge on an object, and then test different materials to determine which build up more or less electrostatic charge.
This lesson focuses on the path of electrons through a closed circuit. Students will experiment by creating three circuits with light bulbs: a simple circuit, a series circuit, & a parallel circuit. They will use their observations to explain why a string of lights wired in series will all go out if one bulb is removed, but not if the lights are wired in parallel. Students will then explain that energy is converted into different forms by electrical circuits.
This lesson introduces electromagnetism as students explore electric current producing a magnetic field. Students build and test their own electromagnets, gaining an experiential understanding of how electromagnets work and how to modify the magnetic fields they produce.

This lesson will be paired with another activity-based mini lesson, which will vary based on instructor/teacher preference and class time/requirements.
The ability to create and follow clear, ordered plans is a vital life skill and is especially important in science. Thinking in a stepwise fashion is necessary for making just about everything, e.g., furniture, lasagna, computer programs, and laboratory experiments. Students will experience this mode of thinking from the point of view of both creator and user. They will first build an object with blocks and write clear directions to allow their partner to replicate their creation; they will then try to follow the written directions of their partner. Students will then discuss what could have made their procedures easier to follow.
This lesson challenges students’ observational skills—one of the most important basic scientific process skills. Students will learn how to distinguish between subjective vs. objective observations and between quantitative vs. qualitative observations. They will test these skills with a mystery object challenge: students will need to observe objects, describe them, and see if their observations allow their peers to correctly guess their object.
This lesson gives students experience developing a physical model in order to understand how an unknown system (a mystery tube) works. Students will observe the system, then design, build, and test their own models so that they behave the same way as the unknown system.
We classify things on a nearly daily basis, as a way to organize observations, describe relationships between different things, and communicate clearly with others. In this lesson, students will understand the importance of classification in scientific practices and will come up with their own classification system for a collection of random objects.
Students will learn the difference between estimating and measuring. The difference between precision and accuracy will be explained. Class measurements will be plotted to demonstrate the importance of taking multiple measurements. Students will be taught that precision is largely a function of the measurement tool, and accuracy is a function of the user. Advanced students will be introduced to the concept of significant figures. This lesson is aimed at 4th – 6th graders, or students who are not familiar with measurements and estimations.
Using a ruler drop procedure (testing reaction time) as a starting point, students will develop a testable hypothesis and design an experiment around it. Students will identify independent, dependent, and controlled variables and outline an experimental procedure. They will then critique another group’s experimental design. If there is time, students may carry out the experiment in class.
In this lesson students explore different ways to analyze data including calculating the central tendencies of mean, median, and mode. Students will focus on correlating their data to real world applications.
This lesson provides a conceptual introduction to the normal distribution, its occurrence in nature, manufacturing, and scientific measurements, and its usefulness in analyzing data to minimize the effect of random errors. Students generate simulated data sets with approximately normally-distributed error, exchange them with each other, make histograms with the data, and analyze it to find the central value. Analysis may be visual, numerical, or both.
SP21- Mini Lesson Nature of Science
This activity is for use on the first day of teaching. The purpose of this short activity is to get students to begin thinking like scientists and to demonstrate the importance (and excitement) of being an active participant in the scientific learning process. With scientific inquiry, students will begin to appreciate that as their knowledge of science increases, their scientific perspectives will also change. This hands-on lesson will prepare students for the active learning they will be involved with throughout the year in their science classes.
SP22- Team Building Mini Lesson Cup Stacking
This activity can be used on the first day of teaching following the introductory lesson (SP00) or at the start of a new semester. The purpose of this short activity is to promote team building. The majority of lessons that we teach during the academic year involve group work. Developing good teamwork skills at the beginning of the year will prepare students for the active group work they will be involved in throughout the year in their science classes.

Ciphers and codes have been around since the ancient Egyptians, and are one of the oldest forms of secret communication. Cryptography is the science of encoding and decoding secret messages. Students will be introduced to a series of ciphers, including transposition and substitution ciphers, and will discover techniques for encoding/decoding secret messages. Younger classes will explore letter groupings, the Jefferson Wheel, and the scytale and pigpen ciphers. Older classes will complete an alphabetic letter frequency analysis and learn how this process can be used to break a code. All students will investigate a monoalphabetic substitution cipher using a Caesar Cipher Wheel.

What happens “behind the screen” when we click on a button or type in a URL on our computer? This module presents the basic structure of a web page and will help students understand what happens when they visit a webpage. Student teams compete to “load” their webpage fastest, modeling the operation of a browser: they use simple HTML commands, travel through a model network to retrieve files from servers, and assemble the text and images to create the finished webpage.
After an introduction to the idea that we leave a digital footprint when using the Internet, students will be given social media profiles and search histories of Internet users. They will then be asked to infer personal data about these people based on the information they can gather from their social media sites. Students will then decide what material is appropriate and safe to share online and what material should be kept private.
