Science Lesson Plans
Students conduct a variety of exploration activities on various science topics. In this science instructional activity outline, students design a cell encapsulation to hold a specific type of medicine. They give examples of physical and...
Curated OER
Density Of A Material
Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.
Curated OER
Hot Food
Students compare and contrast photosynthesis and chemosynthesis as processes that provide energy to biological communities. They investigate the energy content of hydrocarbons used in coral communities.
Curated OER
Calorimetry
Students investigate calorimetry and set up equipment to measure calories. In this calorimetry lesson plan, students make a calorimeter and compare large amounts of heated water with small amounts to show the difference in calories....

Density Column Lab - Part 2
Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the liquids...
Curated OER
To Float or Not to Float - A Lesson on Density
Students define density in their own words. In this physics lesson, students calculate density using mass and volume. They explain why some objects sink and some float.
Curated OER
Qualitative Vs. Quantitative
Fourth graders examine the difference between qualitative and quantitative observations by doing a simple lab activity. This instructional activity can be used at any grade level. It involves the basic observation process skill.
Curated OER
CheMATHstry That Sticks Right to You
Students find the percent composition of sugar in the gum. In this chemistry instructional activity, students calculate percent error from the experiment. They use dimensional analysis to convert between units.
Curated OER
What Floats Your Boat?
Students discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.
Curated OER
Permeability of Earth Materials
Students observe and classify the permeability of a variety of materials.
Curated OER
How Dense Are You?
Students examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
Curated OER
Testing Termites to Discover
Learners design an experiment to discover how termites respond to their environment.
Curated OER
Designing a Flotation Strategy for the Purification of Recycling
Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...
Curated OER
Mining for Natural Resources
Students discover that mining for nonrenewable natural resources has a dramatic effect on our environment. They gain an understanding of the processes involved in harvesting a natural resource and the impact it has on the earth.
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...
Curated OER
Towel Testing
Students examine how to design and implement experiments. In this paper towel experiment instructional activity students test the strength of paper towels.
Curated OER
Soil Comparison and Analysis
Students perform tests on different soil samples. In this earth science activity, students classify the soil into groups according to test results. They write a lab report following a certain criteria.
Curated OER
Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
