Learners explore the concept of how brakes can stop or slow mechanical motion. They examine the operation of a bicycle brake and use low cost materials to devise a simple braking system. Finally, they work as a team to suggest...

There's no need to have friction among instructors regarding the resource. Pupils investigate how marbles and coins slide along different surfaces which gives them information to estimate coefficients of friction.

Twisting and turning through the sky, roller coasters are popular attractions at amusement parks around the world, but how exactly do they work? Explore the physics behind these thrilling rides with an engineering design activity....

Students compare and contrast where friction occurs in robots and bicycles. In this science lesson, students label the diagram of bicycle and robots. They investigate how friction affects their different parts.

What's the best way to use a simple machine to solve a real-world problem? Scholars construct their own simple and complex machines to explore the concepts of work and force. They discuss examples of simple machines they have found in...

Middle schoolers watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which...

Students investigate pulleys and pulley systems. They demonstrate how multiple pulleys dramatically reduce required force. They study hoe pulley systems are used in machines and impact everyday life.

Middle schoolers learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally...

How are forces and motion important to a swing set? Scholars explore the concepts of force and motion using swing sets. In preparation for their own STEM design project, individuals take surveys and data from peers, complete labs on...

Planning an elementary science unit has never been simpler! These twelve lessons guide young scientists through an exploration of simple machines and their many uses in the real world before asking them to apply their learning...

Perform an activity on performance testing with a lesson focused on the purpose of wheel bearings on skateboards. Learners conduct performance testing on a skateboard to collect and interpret data.

Learners examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

Students research articles about science technology and society. In this science and technology instructional activity, students answer questions about an article they chose. They share what they learned with their peers.

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

Students work in teams to investigate how aerospace engineering relates to sports, especially golf ball design and the physics of bounce. They use this information to determine whether these aerospace principles can be applied to...
