Graphing Water Temperature
Students graph water temperature using probe software and a Palm on a class field trip to a lake or pond. Emphasis is placed on collaboration with high school science students and the use of ImagiProbe software.
Nuffield Foundation
Measuring Respiratory Quotient
How do scientists prove tiny living things respire? Young scientists build a respirometer and measure respiration rates in living creatures. By comparing the measurements of both plants and animals, they understand the similarities.
Science 4 Inquiry
Investigating How Heat Flows
It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...
Curated OER
Cold, Clouds, and Snowflakes
Students explore satellite data and graphing. In this weather data analysis math and science lesson, students analyze NASA satellite data to draw conclusions about geographical areas where precipitation might have happened. Students...

#24 How Much Air Is In Foamed Polystyrene Products?
Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...
Curated OER
The Cloud Case
Students discover how clouds form and how air pressure and air temperature affect their formation. The lesson plan is delivered in the story of Mike Breezy, Air Detective, who tries to solve The Cloud Case.
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.
Curated OER
Lead and Mercury Ion Catalase Inhibition
Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.
Beyond Benign
Exothermic and Endothermic Reactions
How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...
Curated OER
Fahrenheit Follies
Second graders analyze the effects of sunlight on a glass of water by using the thermometer to measure its temperature. They predict and measure the difference between water outside in the sun and shade and inside. They role-play a game...
