Blocks And Screws (or "screwy Contrivances")

Students are introduced to how the process of evolution works. As a class, they review the characteristics of natural selection and how those with advantageous traits reproduce and survive. To test this theory of natural selection,...

Simplify students' lives with this physical science note-taking guide. From inclined planes to moveable pulleys, this resource supports young scientists with defining each type of simple machine while identifying their mechanical...

In this simple machines science worksheet, students read about simple machines, mechanical advantages, calculating mechanical advantage, output force versus input force, and distance effort versus distance of resistance. Then students...

Students construct an evolutionary tree representing specialization, diversity, and selection using easily obtained materials. They use at least twenty pieces of hardware to classify then develop "evolutionary" relationships between the...

Students investigate the characteristics of simple machines. In this simple machine lesson, students investigate work as a product of applying constant force. They answer questions about what happens on Earth and what may have happened...
