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 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 conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

In this lesson, students conduct experiments and compile information into a research paper.

In this lesson, students will identitfy several forms of acid precipitation. They will list effects of acid precipitaiton and explain the actions that cause the damage. Students will define "buffering" and explain how environmental factors can act as buffers.

Students develop an understanding of how aspirin works and how understanding its interaction with other chemicals in the body aided doctors in medical research.

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 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 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.

Students will learn to identify and define acid and base and classify household chemicals as acids or bases using universal iindicator.

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 lab activity, students will test the pH of a number of common substances.

In this animation students will learn about refraction and how sound waves influenced the outcome of several Civil War battles.

Students learn terms related to the immune system and define what acquired and passive immunities are and how they differ.

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.

This lesson employs direct instruction and small-group discussion to help students learn new vocabulary skills while reading Patricia Polacco?s Pink and Say.
