Students explore the difference between compound and simple machines in this six lessons of this unit. The purpose and importance of a variety of types of simple machines and the effects of friction are investigated.

Young scholars shake a box containing Plaster of Paris "rocks", gravel, and sand, to measure the effects of erosion. They work individually during this exercise. This task assesses students' abilities to make simple observations,...

Young scholars explore sound wave motion and conduct simple experiments to demonstrate how sound travels.

Second graders study Benjamin Franklin and participate in simple experiments in electricity.

Students perform experiments with water to observe the principles of evaporation and condensation. They make models of the water cycle and discuss the processes that occurred in their experiments with their jars of water.

Students investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.

Students examine the different types of electric motors including their history and classification.  In this motor lesson students complete several experiments with different motors.

Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.

Students investigate the relationship between work and mechanical advantage. In this physics lesson, students calculate the work and efficiency of pulleys. They identify the different types of pulleys.

Students examine how and when rust and corrosion occur.  For this corrosion lesson students complete an experiment to see why metals rust. 

Learners study Faraday's law of induction and the equations that show how to calculate electromagnetic induction.  In this electromagnetic lesson students complete several experiments on the law of induction.

Students complete a unit on the chemical and technological processes of food preparation. They observe various experiments, describe changes in materials through cooking, identify safety and hygiene issues, and cook various recipes.

Students perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

Students combine the skills and concepts that they have developed to ask a simple question which can be answered on a Petri plate. They ask questions and design experiments for verification through collaboration with their classmates.

Those textbook experiments are no good. Using this simple method you can make a real bar of soap. It's

Students work together to perform simple experiments discovering the properties of air. They share their results with their classmates. They examine how engineers use the properties of air to clean the air of pollutants.

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Third graders are introduced to the concept of gravity by observing different objects being dropped from a high point. In groups, they complete the same activities Galileo did and record their observations. To end the lesson plan, they...

Students conduct experiments involving different parts of the water cycle. In this water cycle lesson, students conduct five simple experiments to demonstrate how the water cycle works. The results of each experiment is discussed as a...

  Students brainstorm about solar energy then construct a solar cooker to test the maximum temperature that materials can reach. In this solar energy lesson, students experiment and record temperature of water in their hot boxes...
