How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

Trees are the star of a three-step unit celebrating Arbor Day. Step one takes an in-depth look into the structure of a tree, the process of photosynthesis, and the benefits of the leafy giants. Step two challenges scholars to create a...

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. 

Blow some bubbles and learn how living things need air in the eighth lesson of this series. Young scientists investigate this important gas by observing bubbles and monitoring their own breathing. A simple and fun activity that raises...

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...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

On September 26, 1991, four women and four men entered the scientific experiment, Biosphere 2; the doors were sealed for two years in order to study the interactions of a biosphere. In the activity, scholars explore biospheres by...

Which of the following can you survive without for the longest time: water, food, or a positive mental attitude? The answer may surprise you. Guide learners of all ages through games, activities, and discussions about surviving in the...

Educate scholars on pollution—air, water, and land—with a series of lessons that begin with a thorough explanation of each type. Learners then take part in three activities to reinforce the importance of reducing pollution. They...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Become a member of the Pollution Patrol and stand up to litter! After discussing the life cycle of seeds and discussing how plants figure into the food chain, young conservationists engage in several activities involving podcasts,...

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

A project-based learning plan focuses on landscapes in the community. After identifying problems, such as dead trees or misplaced automatic sprinklers, learners design solutions, contact local organizations to fix the problems, and do...

Learners take a look at the relationship between organisms in food chains, food webs, and energy pyramids. After an opening demonstration by the teacher, pupils are split up into groups. Each one is assigned an environment such as:...

Engineering challenges are not just man-made ... nature has its own set of them. A hands-on STEM activity has groups designing a seed dispersal system. Each group can only use one sheet of paper — a tough task!
