Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

What is coral bleaching? Tackle a trendy topic with a narrated animation. Through a combination of video and illustration, the narrator introduces viewers to a coral reef, then goes inside a coral polyp to show its symbiotic relationship...

This is one cool resource for teaching about polarity! Chemistry scholars observe electron distribution and molecular shape as they select different non-metals and form bonds. The interactive offers two views, surface charge and electron...

The average person's heart beats about three billion times during their lifetime. In this circulatory system video, learners briefly see the difference between an open and closed circulatory system. The rest of the video focuses on the...

During an inquiry-based lesson, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Wow, the human body is complex! The video explores the importance of oxygen, beginning with exploring why it is needed in combustion and then moving into an organism's need for oxygen. Learners see how glucose, when combined with oxygen,...

How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a lesson that allows scholars to diagram energy flows. 

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments demonstrating their properties, this resource is...

Respiratory systems are different in worms, fish, and human lungs, and each are explained by Paul Andersen with his fabulous SMART Board. How are these respiratory systems similar? Keeping breathing surfaces moist is essential in all...

The thinking, and science, behind hydrogen-powered cars is beautifully demonstrated in this episode. Spangler shows how, by itself, oxygen is not combustible. However, when some hydrogen gas is added, that changes! His assistant scoops...

Did you know that life in the sea generates 70% of our oxygen? If it weren't for the water, we wouldn't be here! Discover underwater mountains and volcanoes and take a glimpse at our negative global impact. What can you do to reverse...
