Attenuation of Light in Water

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

Students use adding machine tape to plot increasing ocean depths and deep sea historical events.

AP biologists or college-level botanists consider in-depth details of the photosynthetic process. They examine the structures in a leaf and the roles that they play. They label neat and colorful diagrams of photosystems and electron...

students investigate light levels under the ocean by conducting several simulations. After creating solutions representing seawater, they shine a light sensor on it to discover how light diffuses and is absorbed by the impurities in the...

In this first land plants worksheet, students read about the major events that allowed plants to evolve on Earth. Students read about the primary and secondary atmospheres, the formation of the ozone layer to protect from UV light and...

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

What makes the ocean blue but a glass of ocean water nearly colorless? Investigators prepare tubes of water to examine the color of water. Scholars discover the relationship between light absorption, color variations, and water depth as...

This Ocean Explorer lesson plan (PDF) explores the questions: What colors, if any, are visible down in the deep sea? What is bioluminescence? Students will learn about white light (visible light), the quantity and quality of light as...

Students explore nautical charts and their symbols, with a bit of fun thrown in.

Students make a water sampler and use proper techniques to collect water.They write a essay explaining the inter-relationship of factors such as temperature, pH, dissolved oxygen, nitrates, and phosphates in a lake that might cause a...
