Curated OER
Ice Cold
Learners design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER
Concentration and Reaction Rates
Students investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction....

Anatomy of the Heart
Tenth graders examine the different parts of the heart. In this biology lesson, 10th graders perform dissection of the fetal pig. They explain how the heart maintains homeostasis.
Curated OER
How Shocking
Students describe the characteristics of polymers and rubbers and how they improve human lives. In this shock lesson students build a shock absorbing structure using different polymer materials.
Curated OER
Who Done It?
Students work in groups to solve various murder mysteries using DNA evidence to implicate suspects. Teams compete to solve the crimes the fastest, while using various scientific methods to accomplish their task.
Curated OER
Chemical or Physical?
Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...
Curated OER
Nuclear Fleas
Seventh graders distinguish characteristics of living things and identify the importance of careful observation. They identify five things that are not alive, but display characteristics of life and list five things that are alive, but...
Curated OER
Introduction to Dissolved Oxygen and Demonstration of a Simple Test Procedure
Students explain the importance of dissolved oxygen in water ecosystems. They describe the aquatic oxygen cycle and the effect of water pollution on oxygen. They make observations, collect data and draw a conclusion.
Curated OER
HOW IS PH DETERMINED?
Learners estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.
Curated OER
Oxygen Levels and Aquatic Plants and Animals
Students design an experiment to test the effects of a change in the amount of dissolved oxygen of water on aquatic plants and animals. Questions are offered for exploration and experiment design. Results are tabulated and conclusions...
Curated OER
Does the Introduction of Pesticides and Fertilizers Alter an Aquatic Ecosystem?
Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.
Curated OER
Amphibians-Frog Dissection
Students compare the anatomy of a fish to an amphibian and that of an amphibian (frog) to a human. They complete a virtual frog dissection to gain some experience prior to the real dissection.
Curated OER
DNA Isolation from Plant Tissue
High schoolers perform an experiment to extract and observe DNA from plant Tissue. They read about the procedure and relate it to the procedure used to isolate DNA from an endangered plant species. This is lesson three in a nine lesson...
Curated OER
Molar Ratio
Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...
Curated OER
Physical Difference and Classification
Learners use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
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
Earthworms
Fifth graders research the earthworm and write a one paragraph report on its anatomy and habitat. They learn about worms and how to dissect them through Video Streaming and virtual dissections, along with actually dissect a worm as...
Curated OER
The Perils of Drinking Water
Students determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.
Curated OER
Frog Dissection Lesson Plans
Check out these lesson plans for both actual and virtual frog dissections.
Curated OER
Transmission of Disease
Students provide names of viral diseases that they would possibly like to be infected with today; listing them on the Smart Board. They then come to an agreement about what virus to use and use beakers of fluids to simulate how viruses...
Curated OER
Seltzer Breath
Learners investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.
Curated OER
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.
