By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

Students observe the effectiveness of detergents on breaking down proteins.  In this investigative lesson students participate in an activity that shows how proteins are broken down in gelatin and fill out a worksheet. 

Students discover algae. For this science lesson plan, students examine what green algae is and where it grows. Students determine the effects of oil, detergent, copper crystals sulfate and lawn fertilizer have on the growth of algae.

Upcoming chemists use chemical reactions to determine relative pH in two different acids. This is a terrific lesson plan for middle schoolers that can stand alone as a practice in precision and lab skills, or as part of the unit on...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

Pupils describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution on...

Lab groups set up an experiment to observe what happens over time in collected pond water when fertilizer, representing pollution, is added. This website does not include student lab sheets, but background information, materials, and...

Learners experience and visualize first hand the importance of proper hand washing through a hand washing experiment with different temperatures of water and with a different length of time to wash. They prevent food-borne illness and...

Students investigate the transmission of light energy. In this light energy lesson, students observe bubbles using different colored filters and record their observations. They also look at a light source through various materials and...

Learners conduct an experiment with bubbles.  In this observation and comparison lesson, students read Bubbles, Bubbles, Everywhere and conduct an experiment where they test different kinds of liquids to see which is the best for a...

Students conduct an experiment. In this environmental protection lesson, students explore how oil spills affect living organisms in an ecosystem. Students work in groups to complete a lab activity and then discuss their findings.

High schoolers use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.

Eighth graders discuss uses and disposal of common household chemicals. They select a household chemical to test for impact on plant germination. Students decide how they want to set up a seed germination project. They design their plan,...

Students complete experiments with three different bubble solutions to determine which one creates the largest bubbles. Before conducting the experiments, they discuss the ingredients in each solution, and make predictions on which will...
