Identifying Elements
Students use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.
Curated OER
Life in Extreme Environments - Lakes Under Ice
Young scholars collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess...
Curated OER
The Solar System: Why do we Explore?
Third graders act as scientists. In this property discovery lesson, 3rd graders explore the substance "Oobleck" (cornstarch, water, food coloring). They work in groups to investigate the substance and make observations as a scientist...
Curated OER
How to Clean Up an Oil Slick
Students explore how an oil spill is contained and cleaned up. They investigate an oil absorbing polymer that is hydrophobic, absorbs up to 19 times its own weight in nonpolar liquids, floats on water, and can be reused or disposed of by...
Curated OER
Water and Polymers
Learners conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...
Curated OER
Slime and Intermolecular Attractions
Students explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.
Curated OER
Chromatography
Learners research types of chromatography and complete chromatography experiments.
Curated OER
Plant Nutrition and Nutrients
Students observe seeds growth and examine the different parts of the seedling. In this biology lesson, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...
Curated OER
Worm Compost & Vermicomposting
Students explore vermicomposting, the species of worms needed and the proper climate for it. In this composting instructional activity students make their own worm compost bin.
Curated OER
Fish and Oxygen
Students explore what factors affect population dynamics, identify factors affecting fish populations, and use Stella to model how dissolved oxygen affects fish populations.
Curated OER
How Much Energy Does the Earth Receive from the Sun?
Students explore energy. In this science lesson, students conduct an experiment in which they measure how much energy is produced by the sun. Students build a calorimeter to measure the amount of energy.
Curated OER
Through Thick or Thin!!!
Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.
Curated OER
Antigens
Students examine antigens including ones found in humans. In this immune lesson students complete several experiments in relation to antigens and antibodies.
Curated OER
Micro-Magic With Sticky Ions
Young scholars view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
