RADIATION PROTECTION: HOW MUCH IS ENOUGH?

Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth lesson in the series of 21 on global warming is composed of three activities that build off one another. In the first...

Here is an outstanding 10-page lesson plan on global warming. Learners discover that there is a lot of controversy surrounding this topic in that the science behind global warming is difficult to prove. The best thing about this plan is...

Gamma radiation, which is harmful, is useful in treating cancers. In the second lesson in a series of four, young scientists take surveys and calculate their yearly exposure to ionizing radiation. Then they read about how harmful their...

What is the real cost of electricity? The real cost is not just the price you pay, but the environmental and economic costs as well. Scholars build, use, and judge the effectiveness of a turbine. They also investigate the environmental...

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or not. 

Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...

There are millions of plant and animal species on the planet, but why do we need so many? Follow along with this short video as it explains how biodiversity helps strengthen ecosystems, allowing them to adapt to change so that life...

No question is a silly question! Vsauce is a website that investigates strange questions. Founder and science educator, Michael Stevens, explains the value of the such questions to an audience and demonstrates by working through the...

Young engineers are instructed to design and build their own solar water heaters. Then, they calculate the efficiency and cost and compare them to commercially available models. This is a full unit for pupils to apply their knowledge.

What do quantum mechanics and global warming have to do with each other? More than you might think. Surprisingly, this video explains how it's not the energy emitted from the sun that causes the problem, but how the infrared radiation...
