Curated OER
Macromolecule Lab
During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

Pipeline to the Coral Reefs
Discover firsthand the effects of internal waves on coral reefs. Through a series of experiments, learners simulate internal waves and upwelling events as they make observations on the movement of water and other debris. They then...
Curated OER
Chemistry in the Kitchen
Students, in groups, combine given materials from an everyday kitchen until a chemical reaction occurs and record the reaction time.
Curated OER
Smooth It Out
Fourth graders describe how weather events such as hard rains and floods cause weathering of the Earth's surface and rocks. They distinguish between erosion and weathering, and comprehend that water and friction show similar results in...
Curated OER
Activity #5 Environmental Effects
Learners explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...
Curated OER
Learning Cycle Lesson Plan
students investigate, develop inferences, and identify general descriptions for each of the three states of matter - solid, liquid, and gas. students investigate water, by observing and stating inferences about, the properties of each...
Curated OER
Density Columns
Eighth graders create solutions with 5 different densities. In this chemistry instructional activity, 8th graders analyze the density of solutions stacked on top of each other. They document their data through graphing. This assignment...
Curated OER
Pipeline to the Coral Reefs
Students discuss the relationship of density to stratification. In this marine science instructional activity, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.
