Comparing Sizes of Microorganisms
Kids compare what printed text looks like with the naked eye and under magnification. They discuss the extremely small scale that must be used to measure the size. They learn about the micrometer unit, then draw scale models of a variety...

Water Quality with Samples
Students recognize whether one wants to drink water, swim in it, or for the health of the organisms living in it. They prepare different water samples to observe and collect samples regarding the water quality.

Red Cabbage Chemistry
Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply.

Acids and Bases—Microscale Chemistry
Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...
Baylor College
Heart and Lungs
With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...
Curated OER
Raindrops Keep Burning On My head
Students investigate the effects and causes of acid rain. They test pH of household items to familiarize themselves with pH scale and compare that information with acid rain solutions. They investigate impact of acid rain via internet...
National Wildlife Federation
Ghost Town
Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...
California Academy of Science
Coral and Chemistry
Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...
Curated OER
Dissolved Oxygen and Respiration
Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...
Curated OER
Water Quality Monitoring
Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
Curated OER
Air, Air Everywhere! Lesson 2: Acid Rain
Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...

ACID RAIN
Eighth graders, in groups, take on the role of either Biologist, Chemist, Health Scientist, or Economist. They complete a webquest in which they must decide what to do about a problem concerning the effects of acid rain. They make a...
