Investigating an Enzyme-controlled Reaction: Catalase and Hydrogen Peroxide Concentration
Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...
Curated OER
Mystical Membrane
Students investigate osmosis, diffusion and a semi-permeable membrane. In this cell membrane lesson plan, students observe the movement of molecules out of a bag filled with sugar and starch into a beaker of water. They test the beaker...

Crustal Sinking
Students measure the rate of sinking of a test tube into a beaker of "glop", representing a model of the interaction between the Earth's crust and upper mantle. This task assesses students' abilities to make simple observations,...
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.

Applied Science -- Science and Math (3B) Pre Lab
Set up stations around your science lab to introduce youngsters to different equipment. They examine a beaker, graduated cylinder, ruler, balance, and thermometer. The said worksheet is not included, but you will find a few useful tips...
Curated OER
The Same but Different Part II
Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...

Maintain Safe Work Environment
Students are introduced to the ways in which they can make their workplace a safer environment. Using an example of an emergency plan, they follow it in chronological order and identify any hazardous materials. They also comply with...
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...

Matter and Energy: Equations and Formulas
Using simple materials, an informative instructional activity demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical...
Curated OER
The Same, But Different Part II
Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...
Curated OER
Heating and Cooling Curves
Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

Calibrating Thermometers
Engage young scientists in the upper-elementary and middle school grades with this collection of simple experiments. Whether you're teaching about heat transfer, density, or potential energy this resource has a lab for you.
Curated OER
The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...
