Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

A video and laboratory investigation are highlights to this lesson plan on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon...

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Seventh graders explore how exercise affects carbon dioxide levels in exhaled air.

Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Students think of one way to detect photosynthesis in plants besides those ways shown in class. They identify the reaction that occurs during photosynthesis. Students define the difference between an acid and a base. They identify acidic...

Students observe the changes between elodea leaves placed in darkness and light.  In this life science instructional activity, students experiment to find evidence of photosynthesis in elodea leaves. Students use indicators to...

Fifth graders identify function of phytoplankton in the biospere by conducting experiments and simulations and reading for information. They detect the presence of phytoplankton in bodies of water by examining ocean in satellite images...

Students discover the cuases of pollution. They investigate different pollutants that exist. Stsudents research technologies developed by engineers to reduce the amounts of air pollution. Upon completion of assigned activities,...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Students make a comet out of corn syrup, ammonia, dirt, ice cream sticks, and more. In this comet lesson plan, students view how these ingredients turn from a solid to a gas.

Learners complete an experiment to determine how dirty the air is in their local community. They analyze images and discuss the varying degrees of air pollution. They discuss the results of the experiment.

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Students test the pH level of many water samples.

High schoolers work together to test water samples for pollutants. They design data tables to collect and record their observations. They complete discussion questions to end the lesson.

Students discover the types and amounts of particulate matter found in the air. They collect particulates using a Petri dish coated with Vaseline then classify and count the collection under a stereoscope.

Students conduct an inquiry exploring the different kinds of particulate matter in the air. They name three different types of particulate matter found in the air and identify different types of solid particulate matter found in the air...
