Electrons on the Move

Trace pollutants through the environment in the seventh lesson of this series on the science of food. Looking at a picture of the plants and animals in an aquatic ecosystem, learners use dot stickers to represent harmful chemicals as...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Turn your classroom into a greenhouse with a lesson on plant growth. First, investigate the different parts of seeds, identifying the seed coat, cotyledon, and embryo. Then plant the seeds and watch them grow! Measure the new plants...

Students engage in an interactive "hot potato" demonstration to gain an appreciation for the flow of electrons through a circuit. They role play the different parts of a simple circuit and send small items representing electrons (paper...

Students investigate how friction effects the movement of a block across surface areas. In this friction lesson, students experiment with five different surfaces to determine how each effects the movement of a block across them. They...

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...

Set to upbeat instrumental background music, eight slides present pictures of electrical wires, batteries, and appliances, Each slide is accompanied by a few sentences that introduce viewers to concepts related to current electricity....

Learners act out different types of circuits, and create their own circuits using wire, a bulb, a battery and a switch.

Students create lightning with two common objects and observe the colorful "discharge" of electrons on a smaller scale. By exploring the phenomena of static electricity, students relate their knowledge to the real-life weather phenomena...

Students engage in a lesson that is concerned with the concept of static electricity. They conduct an experiment with balloons and make observations of how it works. The data is collected and written down and they define positive,...
