In this chemistry practice worksheet, learners solve sixteen problems including identifying chemical and physical changes, calculating numbers with significant figures, naming compounds and writing formulas and converting from one unit...

Students develop problem-solving, observation, and critical-thinking skills. In this early childhood lesson, students explore the topic of the sun as they notice shadows and light.

In this chemistry activity, learners examine the energy rule of moles and answer the essay questions. The answers are include with the activity.

Eighth graders build and run mousetrap cars in order to measure distance, time, and mass for their cars. They use these measurements to calculate average speed and kinetic energy, then create a slide show to visually explain how the car...

Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...

Young scholars observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that...

Young scholars drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. In seeing how falling...

Studnet identify examples of conduction, convection and radiation. They develop an example of a building envelope. They also describe how heat transfer mechanisms can affect home energy costs.

Learners examine how wind energy is transformed into electrical energy. In pairs, they build miniature wind turbines and measure how much electrical current they produce. They asses the importance of design and position in energy...

Students explore the variety of ways to use solar energy. They investigate the thermal energy storage capacities of different test materials to determine which to use in passive solar building design. They explain how passive solar...

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. Students investigate...

Young scholars incorporate different disciplines into this lesson. In this science lesson, students investigate the use of communicating without words, and how it is different than communicating with words. They discuss the pros and cons...

Fourth graders calculate the mechanical advantage of an inclined plane. In this physics lesson, 4th graders identify the different types of simple machines and their uses. They give examples of compound machines.

Third graders observe light as a form of energy, that it can be reflected/bounced, refracted/bent and absorbed. They explore how different types of light affect our lives as a whole. Songs are researched that involve light (ex. "You...

In this thermodynamics instructional activity, students complete 50 multiple choice questions on thermodynamics laws. They calculate energy in the system.

Students investigate the relationship between impulse, momentum, kinetic and potential energy and aerodynamic drag. In this physics lesson, students calculate data taken from launching a rocket. They compare the theoretical and...

Eighth graders participate in various demonstrations on electricity. In this physics lesson, 8th graders explore static and current electricity. They apply concepts to real world situations.

Students design and construct a solar cooker. They use the Internet to research solar collectors and the process of changing light energy into heat energy.

Seventh graders explain how things moving relate to energy.

Eighth graders explore the roles of science and technology in today's world. They research a topic based on the uses of science in society. Students discuss medicine, power, transportation, water and sewage treatment and stereos, TVs....

Learners apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

A terrific lesson focused on the design process. It begins with a presentation, "Design: Solve a Problem," which lists the steps of the process and then introduces the specific challenge: to build a device that measures wind speed....

Students construct a model airplane, measure distance, and calculate velocity.  In this creative lesson students work in groups to build a model and use it to calculate distances and velocity.
