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...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

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...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

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...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...
