Celt Spoon
Students investigate the invention of a celt spoon. They construct their own in order to make observations. This should include the spinning in opposite directions than that which it is sent. The construction instructions are included in...

Digital Video Lesson Plan: Brine Shrimp
Students participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Exothermic, Endothermic, and Chemical Change
Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...
Curated OER
Demonstrate Your Chemistry
Learners research and evaluate chemical reaction demonstrations that are found on the web. they work in small groups to choose a demonstration that fits a particular category of reaction and then perform the demonstration for the class.
Curated OER
The Perils of Drinking Water
Learners 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
Physical/Chemical Properties of a Burning Candle
Learners 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
Epidemiology: Graphing and Analyzing Health Data
Students graph data on fetal and infant mortality rates collected by the Centers for Disease Control and Prevention. They identify trends in the data and propose potential causes for the trends.
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
Ecological Succession in Pond Water Cultures
Students collect samples of pond water, dried grass, and soil in a jar. They predict the order of ecological succession in their pond water cultures. They compare their expected results with their observed results.
Curated OER
Predicting the Growth of Microorganisms
Students determine where microorganisms might be found around their school. In this scientific investigation lesson, students collect cultures from various locations and place these in petri dishes. They incubate the cultures to see if...
Curated OER
Endothermic or Exothermic That Is the Question
Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.
Curated OER
Enzymes and Jell-O
Learners test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.
Curated OER
Mighty Minerals
Students investigate the physical and chemical characteristics of minerals. They make a list of the uses of minerals found in Illinois. They write a report individually based on their observations.
Curated OER
Painter's Area
Learners demonstrate geometric relationships of finding area of rectangles and squares. They apply determine the quantity of paint needed to cover the area by using the concept of quantity.
Curated OER
Creating Pinhole Prints
Ninth graders produce an image from a negative created with a pinhole camera using the provided materials and create a test strip in 5 second increments to determine the exposure time for a final print.
