Small Appliances Unit
An informative, but not particularly academic, unit about how to use a variety of kitchen appliances. Information about each appliance is given in a handout, as well as instructions for use and a few comprehension questions. This set of...
Curated OER
Enzymatic Action
Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...
Curated OER
Attenuation of Light in Water
Students explore what happens to light intensity as depth increases using a light intensity logger. They construct a PVC model to hold water and identify what factors could influence the amount of light attenuation.
Curated OER
Eating a Variety for Breakfast
Learners describe different types of breakfasts they would like to eat. They make and eat breakfast food.
Curated OER
Kernel Power" Ethanol Fuel from Corn
Students study why corn is a biodegradable, renewable resource. In this ethanol lesson students build models and observe a chemical reaction.
Curated OER
Heating the Atmosphere
Students construct a thermograph for maximum and minimum temperatures for the 2-week period. They illustrate how the earth's atmosphere is heated by convection and conduction currents and evaporation of water.
Curated OER
Jell-O Optics
Learners observe an activity with Jell-O to learn about optics. In this investigative lesson students fill out a handout on the activity that helps them to investigate the index of refraction and the speed of light.
