Bio Ed Online: Measuring and Protecting Skin

Several subjects are addressed within the context of a science lesson about the sun's ultraviolet rays. Elementary earth scientists consider protection of the skin with sunscreens (health), estimating and measuring surface area or an...

Students learn about the vulnerability of skin to solar radiation, and ways to protect it. They compare their skin to that of an orange, and measure the approximate amount of skin that each has. The activity and accompanying PowerPoint...

A post-assessment at the end of a unit on global atmospheric change. Students write persuasive letters about an issue related to it, e.g., the greenhouse effect or ozone loss. The letters encourage the recipient to protect the atmosphere...

A teaching guide with eleven lessons on the atmosphere, and the impact that different kinds of energy have on the atmosphere and ecological systems. The unit and accompanying PowerPoint can both be downloaded.

A pre-assessment at the beginning of a unit on global atmospheric change. It checks understanding of issues around climate change and the impact it has on the environment and on human health. The lesson and accompanying slideshow can...

This activity allows students to make a simple model food chain and observe how toxic chemicals can become concentrated in the bodies of consumers at the top of the chain.

This unit includes a complete set of science lessons that enable students to creatively explore basic concepts related to air and the atmosphere, air quality, and associated issues, such as allergens in the places we live, study and work.

Plants need air, water, soil, and light to grow. Young scholars learn about plant growth and development by conducting an experiment that demonstrates the importance of light to plants.

Students construct possible food webs for six different ecosystems as they learn about the roles of producers, consumers, herbivores, carnivores and decomposers.

Do you know what makes up soil? Soil is a combination of many different living and non-living things and provides raw materials needed by all living things. In this instructional activity students will explore a sample of natural soil by...
