Through the activity, students learn about genetic variation within a population by focusing on the genotype and phenotype of fish color, using wooden fish as a model. Students will investigate the impact of environmental changes on genetic variation and how favorable traits are passed down to future generations. Furthermore, students will evaluate whether dominant or recessive genes are more impacted by these environmental changes. Students should have prior knowledge of Punnett squares.

    AP05-From Genes to Proteins

    This lesson offers a hands-on simulation of how DNA creates proteins. Students are provided with DNA gene sequences, which they must first transcribe into mRNA and then translate into a protein 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.

    AP06–Blood Typing

    Students discover what determines a person’s blood type through a blood-typing activity using simulated blood.

Students will then evaluate their understanding of contour lines by interpreting another group’s map.

    ES06-Lunar Landing Team Challenge

    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.

    ES07-Celestial Mechanics- Moon Phases & Eclipses

    Celestial mechanics refers to the movement of celestial objects (objects found in space).  Using a model, students will learn how the geometry of the Moon’s orbit around Earth and the Earth’s orbit around the Sun result in the phases of the Moon that we observe on Earth. Students will determine how the Moon progresses through its eight major phases and discuss why most Earthlings have only seen one side of the Moon. Older students and longer classes will also explore the causes of solar and lunar eclipses, and their relationship to the phases of the Moon.

    ES08-Solar System

    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. After making observations of a model of relative planet sizes, students will build a model of relative distances of the planets from the sun.

Students will work in pairs with a divider between them.  One student will create an object with building bricks and write how-to instructions for building the object. The second student will then be challenged to use only the written directions of their partner to replicate the unseen structure. The lesson concludes with students comparing their completed designs, critiquing their partner’s instructions, and reflecting on their own work.

    SP02-The Observation Challenge

    This lesson challenges students’ observational skills by demonstrating the difference between observations (quantitative vs. qualitative), inferences, and opinions. They will use these skills for a mystery object challenge: each small group will carefully observe an object in a box, they will then be asked to describe the object they received by writing quantitative observations, qualitative observations, and inferences. The hints will then be read to the class and their peers will guess what object is in each box.

    SP03–Mystery Tubes

    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 mystery tube and it’s external mechanisms. They will then design, build, and test their own models attempting to replicate the external behavior of the unknown system.

    SP05–Measuring Volume (New Lesson)

    By exploring different methods to measure an object’s volume, students will gain a deeper understanding that volume is the space a substance occupies or contains. Students will get a chance to measure the volumes of at least three different 3D figures and explore measuring volume using unit cubes, rulers (& formulas if known), and/or water & graduated cylinders. Students will then share their results and discuss the pros and cons of each method. Older students will also get a chance to use volume by displacement.

    SP08–Experimental Design

    Students will learn about making a testable hypothesis.  Students first use a ruler drop procedure, which will test reaction time. After identifying independent, dependent, and controlled variables in the ruler drop experiment, students will develop a testable hypothesis and outline an experimental procedure to test. They will then critique another group’s experimental design. For longer classes, students may carry out the experiment in class.

    SP11-Mean, Median and Mode (Recently Revised)

    In this lesson, students explore different ways to analyze data including calculating the mean, median, and mode for a given data set. Students will collect measurements of height for students in the classroom to use as their data set.

    SP21- Mini Lesson Nature of Science (Recently Revised)

    This mini-lesson may be used on the first day of teaching following the introductory lesson (SP00) or at the start of a new semester and consists of a fun pair of geometric puzzles. Together they are a metaphor for the practice of science: various sets of data are combined to form a coherent scientific theory, but when new data is found it may require scientists to revise theories and reevaluate their previous ideas about the connections between the data.

    SP22- Team Building Mini Lesson Cup Stacking

    This activity may 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 activity is to promote team building. 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.

     

  • T01-Binary Code, or How to Speak Computer (Recently Revised)

    This introductory lesson explains binary code and its role in any computer. Students will practice counting in binary using cards and then use their new knowledge to encode and decode English alphabetic characters; illustrating how computers are designed to communicate information.

    T02-Biometrics (Recently Revised)

    This lesson explores biometrics – the use of body metrics and calculations –  and its use as an important method of security in our digital lives. Small groups will design and test hand geometry biometrics and identify unique characteristics which could be used in place of a combination lock on a school locker. Students will evaluate the designs and share their observations about factors contributing to the strength of a biometric.

    T03-Conditionals in Code (Recently Revised)

    This lesson introduces the concept of a conditional statement (a feature of programming language). Initially related to students’ everyday decision-making processes, a game is used to allow students to observe the execution of conditional statements as they would occur within the context of running a computer program.

    T04-Cryptography (Recently Revised)

    Students learn about cryptography, the science of encoding and decoding messages to protect information. Students are introduced to different types of ciphers (algorithms, or steps, performed on individual or small chunks of letters) to encode and decode messages.

    T05-e-Trashing our Future (Recently Revised)

    Students discuss problems resulting from electronic-waste (e-waste) that is not properly recycled. Students work through a model of how e-waste is handled in the United States. Students also discuss ways of reducing e-waste and learn how they can make a difference by properly recycling their e-waste.

    T06-Digital Information Networks (Recently Revised)

    Students will learn the basic structure of the connections that form the World Wide Web and will gain an understanding of what happens when they visit a webpage. Either on a gameboard or as an interactive activity, student teams will compete to “load” their webpage the fastest. They will model the operation of a browser by traveling through a model network to retrieve files from servers and assemble the text and images to create the finished webpage.

    T07-Digital Footprint (Recently Revised)

    After an introduction to digital footprints, older students will be given social media profiles and search histories of several (fake) Internet users. They will infer personal data about these people based on the information they can gather from their social media accounts. Younger students will create their own online gaming profiles and then perform a safety review of each other’s profiles. All students will then discuss what material is appropriate and safe to share online and what material should be kept private.
