High schoolers investigate the effects of calcium ions on the quality characteristics of cooked dry beans. In this calcium ion and dry bean investigation lesson plan, students soak dry beans using 2 different soaking techniques and 2...

Fifth graders explore personal health by identifying positive food choices. In this calcium sources lesson, 5th graders discuss the common ways a human can receive calcium such as consuming dairy products. Students view a virtual tour of...

Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

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...

Sixth graders explore foods in the dairy group. In this dairy food lesson, 6th graders examine the nutritional value of dairy foods and determine the proper number of dairy servings per day. Students also evaluate numerous food labels of...

Students determine the solubility product constant and the concentration of a hydroxide. In this solubility product lesson plan, students use a solution of calcium hydroxide to neutralize a known concentration of hydrochloric acid. They...

No one likes kidney stones, but they are very interesting to learn about. The last installment of a three-part unit has learners experiment with different chemicals to see which one inhibits the growth of calcium oxalate crystals (which...

Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

Budding chemists achieve a basic understanding of the role of heat in chemical reactions. An online worksheet gives learners instructions and questions to answer as they investigate the Chem4Kids website and perform a hands-on lab...

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Students investigate water hardness. In this water hardness lesson plan, students determine the water hardness in 4 samples of water after buffering each. By using titration and an indicator, students can determine the amount of calcium...

Students examine minerals as food nutrients and discover their importance as food sources in the diet. Among the learning options are completing worksheets, creating recipes, making billboards, and actually preparing some recipes rich...

Students investigate ways to improve their bone strength. In this bone strength lesson plan, students explore the link between exercise and bone growth. Students study the effects of proper nutrition and exercise.

Students investigate oral hygiene.  In this personal health lesson, students discover the parts of a tooth and how to best protect them from disease.  Students examine the effects of acids on tooth enamel and calcium.

Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.

Students test different water solutions for the presence of ions. In this water testing lesson plan, students test for iron, calcium, chloride and sulfate ions in solutions. They indicate positive tests based on their results and they...

Students investigate the rate of a chemical reaction. In this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate. They...

Third graders describe and identify the parts of the skeleton and how they support the body. They observe two chicken bones that have been soaked in vinegar for 5 - 7 days. They observe the bone's appearance after it has been removed...

Learners research human health by reading an educational story in class. In this oral health instructional activity, students identify the importance of brushing their teeth and consuming calcium. Learners read the book A Teeth...

Young scholars collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.

Eleventh graders study osteoporosis and understand the relationship between calcium and bone mass.  In this investigative lesson students participate in an activity in which they graph and construct basic bone biology.

Students respond to a poll by actively moving in response to prompts. In this dairy nutrition instructional activity, students write sentences in groups using vocabulary words from a word list. Students discuss physical activity and how...
