An excellent activity awaits your young scientists! In it, learners are invited to explore the world of pulleys, levers, and planes; simple machines that make lifting heavy things much, much easier. They watch video, and engage in...

Seventeen pages of material leave you well-prepared to carry out this lesson on levers and pulleys. Photos and diagrams make the instructions clear; resource links provide additional information. The missing aspects of this teacher's...

Students investigate the scientific concept of mechanical advantage. They construct their own system with the use of a simple broomstick. Then the demonstration is done to show how the mechanical advantage is used to move a load.

Learners analyze an engineering problem. They contrast paper and pencil mastery of concepts with hands-on mastery. They present their design and rationale behind it, whether it works or not.

In this simple machines scientific investigation worksheet, students follow the provided procedures to examine how pulleys work and then respond to 2 short answer questions.

In this machines worksheet, students draw a "Rube Goldberg" style machine which uses 3 different types of simple machines to complete one task.
