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.

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.

Students test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

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 comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

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...

Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...

Learners explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.
