Air, Air Everywhere! Lesson 2: Acid Rain
Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...

Investigating Properties of Water: Temperature
Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...
Curated OER
Polymers
Students explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

Esters: The Secret of Natural and Synthetic Fragrances
Students investigate esters, make an ester and detect esters in natural foods and plants. In this esters lesson plan, students detect smells of hidden objects, produce an ester using peas, brown sugar and apple and demonstrate how to...
Curated OER
Life in a Forest Stream
Students assess macro-invertebrates from a stream. In this science lesson plan, students observe, classify and identify organisms found in a stream. A lab station is constructed at the stream sight and students study the different...

Can Acid and Bases Remedy the Body?
Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.
Curated OER
Thermoset Polymers
Students complete a lab activity with polymers to allow them to better understand how to make "observations". In this science lesson students make measurements and collect data.

Teaching about the Effect of Photosynthesis and
Students demonstrate the effects of photosynthesis and respiration. They decide which variables to analyze in a microcosm study. They produce a written paper, oral presentation, poster, or multi-media presentation
Curated OER
Auxin: Indole-3-Acetic Acid (AAA), A Hormone with Diverse Effects: Synthesis and Applications
Students synthesize Indole-3-Acetic acid from 3-indolylacetonitrile. For this biochemistry lesson, students determine the effect of different concentrations of IAA on lima beans. They explain how hormones help in plant development.
Curated OER
Phytoremediation
Students participate in a lab designed to facilitate the clean up and remove of substances ranging from heavy metals to dynamite. They focus on the remediation of copper. They discuss their results of this open ended inquiry experiment.
Curated OER
Off Base
Students study La Chatelier's principle and identify how carbon dioxide may affect pH. In this coral lesson students complete a worksheet on pH and observe a lab.
Curated OER
How Do I Get a Pure Sample of the Molecules I Make?
Students initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...

Into the Pond
Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.
Curated OER
Losing An Island
Students examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres. In this pollution instructional activity students complete a lab activity to see the impact of gases on the environment,
