Learners explore elements by analyzing everyday objects and materials in class. In this carbon lesson, students define several vocabulary terms such as carbon dioxide, hydrocarbon, and carbonate. Learners view a group of items,...

After brainstorming what they know about ocean acidification, youngsters place eggs in acid to determine the effects on calcium-containing organisms, and add carbon dioxide to solutions with sea shell material to discover the impact on...

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

In this carbon cycle worksheet, learners will read about the carbon cycle and study a diagram showing what creates carbon dioxide and what uses carbon dioxide. Students will then complete 4 short answer questions.

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

You may want to change the title of this chemistry PowerPoint to "Identifying Compounds in the Laboratory." Individual slides explain tests that can be performed to confirm what element you have: carbon dioxide, carbonates, and metal...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

In this chemistry worksheet, students determine the number of atoms in each element and select one that is not equal on both sides of the equation. Then they add a coefficient in front of the formula with that element and adjust their...

Students examine the greenhouse gases affecting the atmosphere. In groups, they participate in activities in which they examine the effects of heat on the atmosphere and phytoplankton. They research how the phytoplankton differ in warm...

An overview of acid and base compounds and their reactions is presented with this handout. Pupils name compounds and write chemical formulas. They write net ionic equations and explain how acidic solutions might conduct electricity. This...

High schoolers comprehend the interactions of pH, alkalinity, hardness, and carbon dioxide in aquaculture water. They read the SRAC fact sheet number 464 "Interactions of pH, Carbon Dioxide, Alkalintiy and Hardness in Fish Ponds." ...
