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...

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...

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...

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....

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...

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...

Using stunning computer imagery, this resource introduces life science learners to cells. It zeros in on the animal cell and the function of its more prominent organelles. Additional support is offered in the form of a self-assessment...

Only five slides, but worth the while for introducing upper-elementary zoologists to different animal life cycles. Two types of metamorphoses are explained: complete and incomplete. Stunning photography flows before the eyes of the...

Although the instructional activity 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...

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...

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...

Your back will be covered when you use this presentation to introduce beginning biologists to phylum chordata, the vertebrates. Five classes are defined: fish, amphibians, reptiles, birds, and mammals throughout the eight vibrant slides....

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....

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...

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...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

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...

Our scholarly friends head to the lake to go fishing and are unpleasantly surprised by the algae filling the water. They talk about primary and secondary succession as different ways that ecosystems are changed. Show the short video,...

If only we could harness the energy of fifth graders, our energy problems would be over! The class discusses where different forms of energy come from and how we use them. They complete a chart of the activities that they do daily...

Two very hip teenagers walk through the forest collecting evergreen cones. One teaches the other about gymnosperms: cycads, ginkoes, gnetophytes, and conifers. He tries to convince his friend how amazing cones are, while she defends...

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...

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...

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...

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...
