"Science in Focus: Shedding Light on Science"
A video workshop for K-5 teachers. This workshop uses light as a theme to explore topics in physics, chemistry, biology, space science, and Earth science. Light is a common thread through many areas of science and a natural topic for interdisciplinary science study. Make connections to real world phenomena and explore the behavior of light, the transformation of energy, and the role of light in the weather, the seasons, and the production of food by plants.

Climactic conditions in each season are not just the result of the tilt of the Earth's axis. In this workshop, they examine the effect of light on the weather. The path of light is followed as it enters the atmosphere, and is absorbed, reflected, and... radiated as heat by the land and by the water. A fifth grade classroom is observed as they explore these phenomena.

In this program, participants are shown that light energy that has been absorbed by plants during photosynthesis and transformed into chemical energy can now be transferred to other organisms. Energy is contained within food molecules such as sugar a...nd starch made by plants, therefore when animals eat plants, or eat other animals, the energy is passed to them. However, the transfer of energy between plants and animals is inefficient and there are energy losses.

The tilt of the Earth's axis causes the cycle of the seasons. In this workshop, we'll discuss how different parts of the Earth receive different amounts of light energy that result in the Earth's seasons. In particular, we will look at the tilt of th...e Earth's axis and how the hours of daylight change throughout the year.

Light energy has predictable properties when it interacts with matter that we refer to as reflection and refraction. In this workshop we will explore what happens to light when it strikes a smooth surface, a rough surface, or a transparent surface. I...n particular, we will examine several big ideas about light through viewing demonstrations with light and mirrors, visiting an artist and an astronomer who use mirrors in their work, watching fifth grade students investigate refraction, and listening to experts talk about light.

n this program participants will explore how plants get their food. Starting with seeds, which have their own source of food, the program traces the growth of a plant, the development of chlorophyll in its leaves, and the production of sugar (and sta...rch) in a process known as photosynthesis.

The colors that surround us provide a rich visual experience. In this workshop we will create rainbows and learn how and why these magnificent phenomena occur in the sky. After looking at the Sun's electromagnetic spectrum we will explore the reflect...ion and refraction of photons of light. We will also examine color televisions and look closely at the pixels which form images, and investigate the primary colors of light and pigments.
