Why Do Somethings Wash up on the Beach and Others Don’t?
This fourth-grade unit on wave properties and ocean floor structures starts out with students exploring a perplexing phenomenon where hundreds of unopened Doritos bags were found on a beach. This sparks a series of questions about where these came from and how they got to where they were found. It also leads students to generate ideas for investigations to pursue about the role of wind, currents, and waves as possible suspects that could have moved these bags from where they were lost in the ocean to where they were found on the shore. (PS4, ESS2)
Where Does Our Clean Water Come from and Where Does it Go After We Make it Dirty?
[Under development]. In this fifth-grade unit on earth systems and on the structure and properties of matter, students investigate where the dirty water that drains out of their homes and schools goes and where the clean water they use comes from. (ESS2, ESS3, PS1, ETS1)
Why Do Dead Things Disappear Over Time?
In this fifth-grade unit on interrelationships in ecosystems, students investigate the apparent disappearance of the body of a dead raccoon over time. Their findings lead them to uncover the role of decomposers in this process, as well as the role of decomposers in the disappearance of plant debris over time. Students ultimately track down where the materials come from that all living things need for repair and growth and where the energy comes from that they use to move and stay warm. (LS1, LS2, PS1, PS3)
