Three activities explore why populations of organisms grow or shrink. Learn how a population can be affected by an invasive species or human activities like fishing. In this sequence of 4 activities, learn how weather is affected by: (1) temperature and moisture, (2) geology, (3) barometric pressure, and (4) location. Four activities explore challenges to our environment: (1) plastic in the oceans, (2) carbon dioxide in the atmosphere, (3) electronic waste and, (4) oil spills. In this sequence: (1) Explore our solar system. (2) Examine phases of the moon. (3) Study stars beyond our sun. In this sequence of 3 activities, first design ways to separate household materials. Then, observe chemical reactions using small amounts of cooking ingredients and by baking cookies. In 3 activities: (1) Explore the difference between electrical conductors and insulators. (2) Find out how electricity and magnetism are related. (3) For an extra challenge, learn about series and parallel circuits. In a sequence of 3 activities, learn how engineers solve problems. Design a building. Make and improve a simple parachute. Build a paper bridge and find its flaws. In this sequence: (1) Learn the “language” of computers (binary code). (2) Learn how computers make decisions. (3) Find out how information is protected (kept secret) on the internet and then make your own secret messages.
