Here Today, Gone Tomorrow
Learners study the difference between chemical and physical weathering. They explore the effects of climate on the weathering process.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...

Properties of the Ocean: Change
Students research and create a visual presentation on the seasonal salinity of the Earth's oceans. They apply the research in a simulation of a lab disaster in which they must relabel ocean samples.

Dark Skies: Volcanic Contribution to Climate Change
Students examine how volcanic eruptions affect global climate. They listen to first-hand accounts of the effects of a large volcanic eruption and illustrate a landscape to show understanding. They experiment with the loss of light and...

What's Air Got to Do with It?
Students use M&M's to create a pie graph that expresses their understanding of the composition of air. They watch and conduct several simple experiments to develop an understanding of the properties of air (it has mass, it takes up...

Science: What Happens to Create the Lode?
Young scholars understand how mineral deposits are formed and why they are not evenly dispersed. They create and describe three different precipitates from four solutions simulating mineral ore deposit formation in sedimentary rock.
Curated OER
Let it Grow and See What Happens
Students participate in an experiment in which they try to stop algae from growing. In groups, they develop a hypothesis and test it while making changes to the experiment along the way. They make observations and organize their data...

Quite a Reaction
In this chemical reaction worksheet, students experiment with soda and Mentos candy to observe a chemical reaction. Students describe the reaction, identify the investigation as descriptive or qualitative and make a prediction if the...
Curated OER
Curds and Whey
In this chemical reaction worksheet, learners investigate the reaction that makes curds and whey. They mix milk and vinegar and run it through cheesecloth to collect the solid. Students make observations, read about curds and whey, and...
