Curated OER
Chemical Changes
Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.
Curated OER
Identifying Elements
Students use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.
Curated OER
Changes in Pulse Rate
Eighth graders practice making observations and collecting data after determining a baseline pulse rate then collect data on the changes in that rate with exercise. Students must organize their data and analyze their observations.
