Curated OER
Observing Buffers In Lakes, Ponds And Streams
Young scholars 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.
Curated OER
Boom and Fizz
Students investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.
Curated OER
Human Impact on the Environment and Pollution
Pupils illustrate the impact humans have on the environment through analogies and models. They observe demonstrations of human impact and pollution and create a composite picture of how people can have an impact on their environment.

The Colors of Chemistry
Learners investigate the acidity and alkalinity of common household products in an experiment. They use red cabbage juice and litmus paper to show the difference between strong acids and bases as they work with vinegar, dish washing...
Curated OER
Living or Non-Living
Students examine living and non-living things. In this life science lesson, students are given a group of objects and discuss if they are living or non-living. Students identify and list characteristics of living things.
Curated OER
Gas Laws
Students perform a series of experiments on gas laws. In this chemistry lesson, students analyze the relationship between temperature, volume and pressure. They create a poster summarizing all the gas laws.
Curated OER
Physical and Chemical Changes
Eighth graders distinguish between physical and chemical change. For this chemistry lesson, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took place.

Alka-Seltzer Rockets: How to Build Your Own Rocket
Students create a rocket using Alka-seltzer of baking soda and vinegar. For this physics lesson, students identify the factors affecting the length of time the rocket is propelled. They relate this activity to actual rocket launched in...
Curated OER
Chemical Changes
Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.
Curated OER
Structure of the Earth
Sixth graders investigate earthquakes and volcanoes. They demonstrate fault lines with a folded piece of paper, conduct an erosion experiment, and construct a volcano using clay, baking soda and vinegar.
Curated OER
Chemistry: pH Probe
Young scholars conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases....
Curated OER
Science: The States of Matter
Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Ocean Acidification
Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...
Cornell University
Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.
