Surface Tension
A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...
Curated OER
Swinging Electrons
Students illustrate paramagnetic and diamagnetic differences due to the unfilled and filled valence shells. They prepare saturated solutions and place into test tubes.
Curated OER
Observing Popcorn
Fifth graders discover the process of boiling water and how it is part of the changing of states of matter. They observe a kernel of popcorn pop in a test tube with water and take notes of how the water changes to the form of a gas....

Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. For this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
The Respiratory System
For this respiratory system worksheet, learners compare how much air a person can typically exhale in one breath as compared to others. Then they develop a questionnaire to test their subjects and respond to the questions proposed.

Micro-organisms
Sixth graders explore the world of micro-organisms. For this science lesson plan, 6th graders discover additives which will deter micro-organism growth.
Curated OER
Nutrition
Students learn about good nutrition. In this biology lesson plan, students test samples of food to find out if they contain fat, test fruit juices for vitamin C and compare the vitamin C content of the juices, calculate the number of...
Curated OER
Microbe Experimentation
Seventh graders study microorganisms in their environments by experimenting with milk products. In this microbes lesson, 7th graders read background information about microorganisms in yogurt and soured milk. Students then follow a...
Curated OER
Enzymes and Jell-O
Students 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
Identifying Food Nutrients
Young scholars pretend they are a food-quality tester. They develop a kit to test food for sugars, starches, proteins and lipids. They answer questions to complete the lesson.
