Many fields of study require a specialty and a sub-specialty as you progress through your education. Scholars learn about six sub-specialties of life science. From botany to zoology, our knowledge of the world of living organisms expands...

Mmmmmmm, here is a tasty little slide show to use when introducing upper-elementary learners to the sense of taste. Photographs and detailed computer images accompany explanatory text about how the taste buds and the nose send signals to...

Life science learners discuss the characteristics of five kingdoms of life: animals, plants, fungi, protists, and bacteria in this video. Viewers find out from the dialogue that scientists group organisms according to similarities. This...

Take your kids on a trip through the universe as they explore galaxies, solar systems, stars, and more. Watch the short video, then have learners show their knowledge with the included quiz. Supplement the video by having teams build a...

Expose your class to the steps of the nitrogen cycle with this short clip. Colorful computer imagery and animation explain how nitrogen travels from the atmosphere as a gas into plants and soil, where bacteria convert it into nitrates....

The topic of this video is sure to get hearts pumping! Mia and Zoe just finish racing and discuss what is going on in the circulatory system. They expound on the capillaries, veins, arteries, the structure of the heart, and the...

The greenhouse effect warms up earth enough so it can support life, but if it heats up too much, life won't be able to survive. An interactive presentation covers the greenhouse effect, the carbon cycle, climate forcing, and climate...

How many times have you traveled around the sun? Aspiring astronomers grasp what a year is and they differentiate between orbit and rotation by walking around the sun right within your classroom. Place a lamp in the center of the room to...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Although the lesson is specifically about the San Francisco Bay area, it's good enough to be adapted to any local region. Children research what the landscape in San Francisco was like prior to settlement, they consider the types of...

Tamarin monkey language can be categorized by stem upsweep, duration, peak frequency, and frequency change. Although other complex terminology is used to describe the 38 calls of this species, the video is easy to follow and a...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

Flowers are lovely, but they are also very practical if you are a plant! In this video, kids learn that without a flower, there would be no seeds. They also find out about the two types of seeds: monocots and dicots. Pollination and...

Zoe and RJ discuss the way scientists classify organisms into five kingdoms. Characteristics of each group are highlighted within their conversation and with text. First-time taxonomists can view the animation at home, take the...

Garbage, recycle, compost: Does it really matter where we put our trash once we are done? By making detailed observations over seven weeks, kids will see which materials break down naturally to become a healthy part of the soil, and...

Earth's thick atmosphere plays a vital role in the ability of the planet to sustain life. Learn about the layers of the atmosphere and their properties, how the gases surrounding the earth help protect the planet, and a little about...

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...

Students write from an animal's perspective. In this writing lesson students explore the landscape of San Francisco prior to the arrival of the explorers. Students research animals indigenous to the area.

Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

Mia's friends are fish-sitting while she is away on vacation. Zoe divulges to Sam that different animals need different habitats, and that there are both freshwater and saltwater ecosystems. Examples of the kinds of organisms found in...

Are chickens and crocodiles really related? Young scientists compare the bone structure of current domestic chickens to other animals throughout evolution. This helps them understand the branches that separate crocodiles and birds as...
