Learners list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

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

Learners experiment to determine the difference between an acid and a base. They study the concept of adding a buffering agent to make an acid more basic. They study the pH scale.

Students discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...

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.

Forget your ID number? Your pupils learn to use logarithms to determine the number of digits or characters necessary to create individual ID numbers for all members of a group. 

Students study the pH scale and sources of acid precipitation.  In this acid rain lesson students complete a lab on acid rain then complete a handout.

Students test the pH of various solutions. In this pH lesson, students use litmus paper to test the pH of household solutions. They compare their results with book charts.

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

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...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Acid rain, and how it affects the environment, is the focus of this Earth science instructional activity. During the study, learners evaluate measures to reduce acid rain, and design an investigation to demonstrate the conection between...

Tenth graders participate in hands-on activities that require them to consider the implications of water pollution. In this environmental stewardship lesson plan, 10th graders conduct 6 experiments pertaining to water pollution and...

Students explore pH levels of different substances. In this instructional activity about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to...

Students try to cure an upset stomach. In this acids and bases in the body lesson, students create a upset stomach with a vinegar and water solution, then use antacids and home remedies to attempt to restore pH balance to the mixture.

Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.

Students use supporting evidence to predict if common household substances are acids or bases. They determine the pH of the substances and describe the results of the investigation and characteristics of each substance.

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...

Learners use litmus paper to begin to discover the qualities of acids and bases. They learn about pH by testing clear liquids for acidity with purple cabbage juice as an indicator. The video Streamkeeper, with Bill Nye, and other video...

Students identify substances that are acids and alkalis. In this acids and alkalis instructional activity, students conduct tests to determine if given substances are acids or alkalis. They test substances and explain the different...

Students monitor a local creek. For this environmental water lesson, students conduct an environmental study of a local creek by monitoring the temperature and water quality over a period of time, then submit data to the Global Water...

Students concretely illustrate and define a macromolecule, observe the unique behavior of polymers and relate to their knowledge of molecules, and use the scientific process to determine the difference between Newtonian and non-Newtonian...

Students examine the different properties that affect water quality.  In this pollution lesson students play a game, complete a hands on activity and computer lab.
