A Whole New World: The Search for Water
Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Investigating Acidity
Students classify liquids as an acid, base or neutral. They use purple cabbage juice as an indicator to test several liquids in order to group them as acids, bases or neutrals.
Curated OER
Water Ph
Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...

HOW IS PH DETERMINED?
Students estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

Observing Buffers In Lakes, Ponds And Streams
Pupils observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.

Technology of the Deep: Experiments with Buoyant Forces
Young scholars conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
Curated OER
Water Pollution
Young scholars study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and...
