Students explain necessity in using accurate instruments when measuring, and how measurements can be checked for accuracy. They make a six-inch ruler, design, test, and evaluate a system to measure work, and produce a table and graph to...

Students use the internet to discover the basic concepts in physics. They complete interactive simulations where variables can be changed. They answer comprehension questions to end the lesson.

Students observe examples of gravity, friction, and force on the playground. They then experiment and participate in a variety of activities in centers back in the classroom.

Students, in groups, build and decorate rocket kits and then launch them.

Third graders make a ballon rocket to study the relationship between the force applied to an object and the resulting motion.

Young scholars discover the relationship between force and acceleration in a skateboard experiment. In small groups, they attach a spring balance to a skateboard and pull a group member across the floor using a constant amount of force....

Young scholars investigate the relationship between force and motion while conducting an experiment to answer the question,"How do objects move?". In small groups, they predict how many washers are needed to pull a bowl across a finish...

Learners identify and classify magnetic and nonmagnetic materials and metals. After determining which materials and metals are magnetic, students create a data table and classify items by two different criteria. Learners e-mail various...

Students practice calculating the moment of inertia when discussing a skater and the position in which it is best to spin. After class discussion, students practice calculating inertia on their own.

Ninth graders compare the nature of forces of gravity, lift, thrust, and drag. They select proper materials for making a kite and attach a proper tail. Students interpret and summarize the observations made during the flight of the kites.

High schoolers read Forces in a Climb from the Beginner's Guide to Propulsion, and explain each of the formulas using vectors.

Learners ask questions that can be investigated scientifically. They determine how to plan a fair test by changing one factor while keeping other factors the same, to use measurements to draw conclusions and use scientific knowledge to...

Third graders demonstrate that gravity is a force.

Students explain that air pressure applies a force. If any of students have flown in an airplane, they have felt the "popping" of their ears caused by the change in atmospheric pressure because of the altitude changes.
