Fourth graders identify the different types of renewable and nonrenewable energy sources. In this ecology lesson, 4th graders create models of wind mills and hydropower. They discuss the pros and cons of using alternative forms of energy.

Third graders make parachutes to learn about gravity and the science process. For this gravity lesson, 3rd graders create parachutes and observe their flight in air. Students discuss wind and gravity for the activity.

Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.

Second graders examine how their choices affect the environment. They identify different types of pollution and its source. They ask questions to end the lesson.

First graders study, observe, and use a simple machine. They study necessary safety and review posted safety rules related to using a machine and identify strategies for reporting any accidents or injuries.

Fourth graders discuss the myth of Galileo's experiments in which he threw items out the leaning Tower of Pisa to find out how fast they fell and predict what they think could happen when the two items listed on the same line are dropped...

Pupils watch an episode of the PBS show "Jay Jay the Jet Plane," and explore magnets and gravity. They conduct various experiments involving magnets and sand, bean bags, and a fishing pole with magnets.

In this Isaac Newton activity, students analyze ten words in a word box that pertain to Newton's Law. Students match these words to their definitions.

Students practice the 4 question strategy to form more questions and develop further experiments. The four questions are engage, explore, explain, and elaborate. They use the 4 question strategy on an investigation involving the mass...

High schoolers examine how physics help high jumpers break records. They discuss the phases of the high jump, gravity, and center of gravity, and conduct an experiment to determine whether they can improve the height of their jump.

Pupils discover how air can move things by using their breath. In this physics lesson, students hypothesize then attempt to move a pencil 1 meter using nothing but their breath. Pupils record data from their experiment including...

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.

Learners examine the relationship between water and ice. For this physics lesson, students read the book Amazing Water and participate in an experiment where they freeze water into ice cubes. Learners observe the changes in the water...

Students observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.

Young scholars investigate levers. In this simple machine lesson, students study levers and  the mechanical advantage of using levers. They will collect data and illustrate their systems for eight different tests.

Students build a model of a submersible that will allow them to explore ballasts and how they operate.  In this hands on lesson students participate in an activity that shows them how to control buoyancy.

In this properties of air worksheet, students experiment with a jar, a plastic bag and rubber bands to simulate that air takes up space and exerts pressure. They make observations and answer questions about their experiment.

In this physics worksheet, learners 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 collect data and describe how and why the high and low tides change from day to day.  In exploring tides lesson students study tides by taking notes, recording data and analyzing their findings. 

For this levers worksheet, students read a one page information text about the three classes of levers. Students then analyze 10 pictures of simple machines and circle the fulcrum point. Students classify each machine according to the...

Students explain that mass times velocity equals momentum. They investigate the impacts of collisions and their results and determine the vector of an incident.

Students participate in an online activity to determine how objects heat and cool. They determine what objects best serve as thermal insulators.

Students participate in an online lesson to determine that different plants and animals are found in different habitats. They use food chains to show feeding relationships in a habitat, and see that nearly all food chains start with a...

Students investigate melting and cooling in a range of materials.
