Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

New Horizons set forth on a mission to Pluto in 2006. Ten years later, the spacecraft is still on its way. Here, enthusiastic scholars predict what they will be like—likes, dislikes, hobbies, etc.—when New Horizons arrives at its...

Here is a fabulous set of teacher's notes that will make your next hands-on gravity and force lab fun and interesting. These notes provide you with three activities that allow children to make and test hypothesis regarding force,...

Get your hands dirty with an interactive lesson that showcases the process of decomposing and returning nutrients back into the soil. After building a compost pile, pupils regularly observe the...

Leave it to the classic jump rope to get your class excited about physical activity! Your class will begin by discussing the benefits of jumping rope as a form of exercise and learning a few different types of jumps. Then in groups of...

In this science worksheet, students test objects to see if they conduct electricity. They name the object, record what it is made of, predict if it is a conductor, and record the answer of the test.

Students build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.

Discuss the difference between conduction, convection and radiation of thermal energy, and complete activities with your class by investigating the difference between temperature, thermal energy and the heat capacity of different materials.

Experiment with electric circuits and conductivity. Young scientists will model and discuss how an electric circuit works. First they will draw a model of the flow of electrons and then build an actual circuit. Finally, they will explain...
