Students listen to Nursery Rhymes highlighting GRAVITY, pull ropes during a Rope Pull Activity and even drop eggs from a height during a Gravity Contest. This is a fantastic lesson which highly motivates Students!

Sometimes, we all need somebody to lean on. Scholars create a human arch by leaning against each other. They consider different approaches to making the arch sturdier and stronger.

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

When is it okay to be suspended in school? When you're part of a human suspension bridge! Learners first model tension and compression in pairs. Once complete, they get together as a class to model a suspension bridge.

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

A lever comes in handy when scholars build a launcher for a ping-pong ball. They test the launcher and redesign it to send the ball higher or to accommodate a tennis ball. This is the third lesson in a five-part unit.

Students infer that there are forces we cannot see that act upon objects, experiment with magnets to show a push and/or pull force, and participate in a magnet game.

Fourth graders explore Newton's second law of motion, testing and identifying the characteristics of objects that makes them easier or harder to push. They identify what types of objects are the hardest to move, then test a variety of...

In this pulleys, levers and incline planes learning exercise, students answer 22 questions about output force, energy loss, and net force on pulleys, levers and incline planes.

Students determine the forces necessary to move a truck on an inclined plane with weight and slope as variables. They identify the cheapest way to transport trash to local garbage disposal sites.

Students examine how simple machine work can make work easier.  In this machines instructional activity students complete an activity that shows them what makes up a machine, and how to measure displacement and velocity. 

Can you build it? Yes you can! This interactive game includes four design challenges presented on separate cards. The cards outline the challenges with limited restrictions but with an end goal in mind. The competitions include building...

Students are told that the weight of a car is equal to its mass multiplied by the acceleration due to gravity. When a car is at react on a horizontal road, there must be a normal force with which the road pushes up on the car to keep it...

Students explore modeling of geologic structures in experiments. They study how compressive and tensile forces produce these structures. The compression makes the flatlying strata shorter and tension make the strata longer.

Students examine how gravity affects launching rockets into space. In this physical science lesson, students review the concept of gravity and use an interactive online site, "Gravity Launch," to simulate a rocket launch.

Third graders discuss the collection of toys and demonstrate to the class how a given toy moves. They discuss the part of this toy that could be broken or missing to cause the toy not to work. Which parts could be broken and the toy...

In this physics activity, students investigate Newton's Three Laws. In this multiple choice, matching, and short answer activity, student answer eleven questions.

In this paper helicopter worksheet, students design and experiment making a paper helicopter to explore how some things fall and how varying the size of the rotor blades affect the way a helicopter spins.

Young scholars use balloons and string to duplicate Bernoulli's Principle of wing shape and its affect on liftoff.

Students use inquiry and observation to explore Newton's third law of motion: for every action there is a reaction. In this physics lesson, students rotate through six stations set up with materials and picture directions illustrating an...

In this electricity instructional activity, students review topics related to electricity such as circuits, voltage, electric fields, and resistors. This instructional activity has 21 problems to solve.

In this object in motion worksheet, students will brainstorm ideas of what can change an object's motion. Then the student will write in supporting details for each idea in a graphic organizer.

Young scholars investigate how to make a lever. In this construction lesson plan, students explore how to construct a lever using dog and tail templates, cardboard, and fasteners. Young scholars construct their simple machine in order to...

Students work together to test the strengths of various types of magnets. After testing, they create a graph showing how the strength changes as the distance from the magnet increases. They discuss how forces can act from various...
