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 activity 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. 

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...

In this observation worksheet, scientists observe a burning candle and answer eight post-lab questions. Topics include the phase changes occurring during the observations, the role each part of the candle plays in the chemical reaction,...

An outstanding lesson awaits your physics fledglings! After reading about how hydrogen can act as an energy carrier, they examine the electrolysis of water using solar power. They test the gases produced for flammability and will...

Students watch a video about climbers on Mount Everest. In groups, they complete experiments in which they determine the concentration of oxygen in the air. They make predictions before beginning the experiment and complete a worksheet...

The oxygen needed by our bodies to burn during respiration of glucose is obtained by ventilation. The anatomical structures involved in gaseous exchange are drawn and labeled. The explanations are excellent for a review, or for a student...

Watch as the Khan Academy explains why red bloods are efficient carriers of hemoglobin and explains the difference between pulmonary arteries and veins. This thorough video with great explanations and diagrams will surely help your...

Students reverse engineer a cereal. In this dietary lesson students identify the minerals that the human body needs to function. Students examine how foods are fortified by food engineers. Students find the amount of iron in a cereal by...

Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Salman Khan is very enthusiastic about the topic of cellular respiration! He provides an interesting presentation of the respiration process. Expect to learn about the basic stages of respiration, how it works in the human body, and the...

New ReviewAdd a little heat to your science lesson. Young experimenters work to understand the chemical reaction taking place when a candle burns. They experiment with both oxygen and carbon dioxide to make conclusions about the reaction.

New ReviewGive them permission to burn. Using a tea candle, pairs find out how long the flame will continue to burn while covered by a small glass. Using that information, groups estimate how long the candle will burn under a larger drinking glass...
