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...

In this limestone worksheet, students name three sources of calcium carbonate, write the chemical formula, and determine the three elements found in calcium carbonate. This worksheet has 7 short answer and 3 problems to solve.

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 demonstrate their understanding of a body's need for calcium by constructing healthy diet habits with calcium rich food.

Explain, distinguish, list, and describe the structure and function of the human endocrine system. Medical school hopefuls also diagram how calcium, glucose, and osmotic levels are regulated in the blood. This activity is suitable for...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Individuals analyze tree rings to determine the health of an ecosystem. They then look at otoliths of fish, hard calcium carbonate structures located behind the brain, in the same manner. 

Calculate the nutrients in different types of dog biscuits. Pupils create a technical report outlining the amount of calcium, protein, and carbohydrates in three types of dog biscuits. The project-based learning activity requires...

Many pupils mix up the chemical symbols for calcium, carbon, and copper. These entertaining puzzles help scholars remember the names and symbols. First, they match the name and symbol of 12 elements. Then, through a series of three...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

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...

In this vitamins and minerals worksheet, learners review how these are measured and determine what minerals the body needs. Students determine how different vitamins help the body to function properly. This worksheet has 22 short answer...

First graders examine body systems and demonstrate their competency in a quiz game show. Lessons cover the brain, heart, lungs, digestive system, muscles, and bones. Students , in teams, answer teacher-created questions in the game.

Students identify human muscles and bones from a cardboard skeleton, named "Mr. Skelly." Using dialog balloons as props, the teacher holds up advice from Mr. Skelly, such as noting he drinks milk to keep his bones strong. The lesson...
