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...

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....

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...

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.

Identify minerals, their sources, functions, and deficiencies in the body. National Standard 14.2.1 Discuss macro minerals, electrolytes, and trace minerals Identify the problems associated with calcium and iron

High schoolers 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...

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...

Tackle polyatomic ions with Sudoku-like games! Nomenclature novices practice identifying the names and constituents of carbonate compounds with a series of puzzles. Scholars can use the resource online or as a worksheet, thanks to the...

In this limestone reactions learning exercise, students read about the various types of limestone reactions and complete a diagram of deposits in a cave. They answer two questions about limestone reactions.

In this chemistry worksheet, students identify ways to memorize the elements and symbols of the periodic table for chemistry. They identify phrases that use each element in a unique way.

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...

In this chemical reaction worksheet, students investigate the results of mixing calcium chloride with sodium bicarbonate. They observe the chemical and physical changes that occur, identify the properties of the chemical before and after...

Young scholars discover the importance of calcium in their diets. In this nutrition lesson, students participate in an activity that requires them to conduct surveys regarding dairy and assessing what they eat. Young scholars discover...

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

In this chemistry worksheet, students balance the list of equations given using their knowledge of the Periodic table. There are 27 equations to solve on the sheet.

Students identify the risks associated with osteoporosis. In this adult health instructional activity, students compare their current calcium intake versus what they need daily. They recommend ways to prevent this disease.

Students examine the impact of dairy nutrients. In this nutrition lesson, students participate in interactive activities that require them to consider how much calcium their bodies need. Students also visit the school cafeteria and...

High schoolers 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.

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

In this chemistry worksheet, students determine the vapor pressure of a solution when dissolved in water at a set temperature. Then they determine the vapor pressure of this solution at a higher temperature. Students also explain the...

In this chemistry worksheet, students balance each of the reactions presented using the periodic table to help. Then they predict the products of the reactions and write the net ionic equation. Students also write the empirical formulas...

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