Curated OER
Mixtures
Sixth graders experiment with mixtures. In this chemistry lesson plan, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
Curated OER
Determining pH
Pupils evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Pupils complete their own pH level experiment. Students go to the GEMS Alien Juice Bar website to test...
Curated OER
Did a Chemical Reaction "Really" Occur?
Students perform several different experiments to observe signs of chemical reactions and determine if reaction has occurred, use search engine to find Internet sites pertaining to chemical reactions, and write up brief summary of site.
Curated OER
Chromatography
Students conduct various experiments on chromatography. In this chemistry lesson, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.

Come Shine with Us: Floor Polish Testing and Industrial Science To Teach Critical Thinking
Students discover that science relates to everyday life and see testing procedures used in an industrial laboratory. Students compare various brands of household and industrial floor polishes for specific criteria.
Curated OER
Mystery of the Eleven Unknown Substances
Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.
Curated OER
Conservation Station
Second graders, in groups, measure the volume of four containers that vary in shape and size.
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. In this science activity, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...
Curated OER
CO Buildup City
Students conduct a controlled experiment. They collect data in an organized manner. Students analyze data to reach a conclusion and communicate findings. They explain how city size, temperature, and pollution is related to the air quality.
Curated OER
Yo-Yos, Tow-Yos and pH, Oh My!
Students explore how hydrothermal vents are formed and where they are located on the ocean floor. They study how scientists use CTDs to locate hydrothermal vents.
Curated OER
Warm and Cold Air
Students examine what happens to air when it is heated or cooled. They conduct an experiment using bottles and balloons, record and discuss their observations, and write a hypothesis.
