Energy Sources

Learners complete a series of activities related to forms of energy. In this energy lesson, students look at forms of energy in their school, how energy is conserved and used efficiently, how magnets are used to generate electricity, and...

Why do athletes load up on carbohydrates the evening before a competition? The lesson helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars perform an experiment to...

Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

Charles Darwin and Jean Baptiste Lamarck are credited for developing the theory of natural selection. After teaching your beginning biologists about acquired characteristics, they read the included selection and answer questions that...

The lecturer describes how certain characteristics develop. In this case, he discusses eye marking. The impact of environmental factors plays a huge role in the probability of successful reproduction and the fact that favorable genes...

The peppered moth is featured in a video about natural selection. The narrator tells the story of Darwin's theory and then moves on to the principles behind natural selection and the different ways it works. Concepts covered include...

If renewable energy sources are the best option, why aren't they used on a global scale? Junior environmentalists explore the benefits and problems associated with energy sources such as solar, wind, and biomass with a short video and...

A hands-on simulation perfect for an economics lesson, young learners investigate the availability of different sources of natural energy (coal, natural gas, oil, solar, and nuclear) and how this availability affects their cost. Simulate...

Teams of electrical engineers work together to develop plans for increasing electricity to a fictitious, but growing community. They consider different sources of electricity, both renewable and nonrenewable, the cost of building and...
