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...

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.

Does Newton's First Law of Motion explain how to move a sled across ice? A simulation encourages scholars to decide if they should push, pull, or apply no force. Their decision moves a sled across the ice and to the home at the...

Students conduct individual research and participate in discussion be able to identify difference between forced and voluntary migration. They identify if push and pull factors are caused by political, social, economic, or environmental...

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

Students examine pictures of different animals and decide if they eat meat and/or plants. They inspect models of pairs of upper and lower teeth and discuss which teeth are most useful for cutting grass and tearing meat.

Students complete food chains for organisms in three environments. They use copies of the Habitat worksheet. Students review the food chain terms with the teacher. They research related food chains, and interlink these to form a food...

Students experiment with solids and liquids to find which solids will dissolve in water. This dissolution and mixtures lesson plan can be completed online or in class as all materials are connected to the lesson plan for both settings.

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.

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 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.

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 conduct an experiment about air volume, density, and pressure. In this air lesson, students discuss air, and how it moves. They make predictions about what will happen during the balloon and string experiment. They document the...

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 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 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...

Students are introduced to the power of magnets. In groups, they look at different objects and make predictions on whether they believe they are magnetic or not. They test their predictions and share their results with the class.

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.

In this physics instructional activity, students complete each of the statements with the correct word or phrase. Then they match each of the words listed on the left with their correct descriptions on the right.

Students observe an on-line activity to review the basics of electrical circuitry, then research answers to related questions on-line.In this lesson on changing components in a series circuit, students discover how different components...

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.

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...

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.
