This interactive activity demonstrates and provides explanation for how acid rain affects aquatic ecosystems and how certain species react to decreased water quality as pH becomes lower. The activity also explains the pH scale as a measure of acidity.
This lesson plan includes two activities designed to demonstrate the effects of …
This lesson plan includes two activities designed to demonstrate the effects of acid rain on physical structures such as rocks, buildings, and statues and on living organisms (plants). In the first activity students will make observations after dropping samples of water and vinegar on chalk. In the second activity students will plant bean seeds to produce three separate bean plants. One plant will be given only water; one plant will be given only vinegar; one plant will be given a 50/50 water/vinegar solution. Students will form hypotheses, and then make observations and collect and graph height data as the plants grow.

Students devise a scientific investigation to detect acids and bases in common materials. Students will prepare a test solution whose color changes when an acid or base is added.
Students are introduced to the differences between acids and bases and how …
Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.
In this activity, students will use a chemical reaction to test for …
In this activity, students will use a chemical reaction to test for the presence of carbonate in calcite and limestone. Students will drop a small amount of acid on mineral specimens and observe the bubbles of carbon dioxide forming from the reaction of the acid with carbonite minerals.
In this lab activity, students will determine the concentration of a solution …
In this lab activity, students will determine the concentration of a solution of NaOH by titration with a standard solution of HCl. They will also determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH.

In this lesson, students read Pink and Say by Patricia Polacco to identify words that are unfamiliar to them. Working collaboratively in small groups, they discuss the meaning of these new words, using context clues from the text, prior knowledge, and both print and online resources. Students then apply their knowledge of the new vocabulary to further their understanding of the text.
