Precise measurements make the job easier! One of the challenges when using an inclined plane for testing comes from pupils not using exact measurements. They often rely on books that slide or different ramp lengths when experimenting. By...

Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Legos in science class? Watch your pupils fall in love with this activity. After learning to measure potential and kinetic energy, young scientists create their own ramps using Lego Mindstorm sensors and software.

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

Young learners explore friction. They view a video or DVD (bibliography provided) and define terms related to friction, and work in groups to experiment with the effects of friction on speed and motion using ramps and toy cars.

After getting to know the inventor, Leonardo da Vinci and his many inventions, scholars think up their own invention. Following a written description and a hand-drawn picture, learners use a method of mirror writing and antiquing to give...
