Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

An educational presentation includes atoms, molecules, the four major elements, as well as neutrons and protons. Additionally, slides focus on atomic number, mass number, atomic weight, polar and nonpolar covalent bonding, ionic...

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...

Chemistry and biology work hand in hand, without one you literally wouldn't have the other. Using a presentation, individuals learn about plant cells, animal cells, cell responses, macromolecules, DNA bases, and so much more. A worksheet...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

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...

Here is an extensive reading resource that addresses our climate change crisis. It thoroughly explains the greenhouse effect, related Earth cycles, and the history of climate change. Use it as part of the intended unit, published by the...

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.

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...

Not a activity in the traditional sense, this is a collection of resources with which you can craft a activity on metabolic processes. It includes an outline of topics, some brief discussion, and a large array of animations, images, and...
