It's Just a Phase: Water as Solid, Liquid and Gas
Students construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.
Curated OER
Inter-State Matters
Students explore the six phase transitions between gases, liquids and solids for a variety of elements. Each group of students focuses on a different element, investigating its physical properties during each of the six phase transitions.
Curated OER
What's the Matter? (Experiments)
Students observe a scientific discrepant event, and are then challenged to create experiments to solve the dilemma.
Curated OER
Asthma
Students experience what it feels like to strain for air in order to empathize with people who have asthma. They create a simple model of the respiratory system to measure the effect of narrowed airway channels.
Curated OER
Healthy Heart
Students explore how the heart works, examine pictures of a troubled heart, and discuss how to keep the heart healthy.
Curated OER
Teaching about the Effect of pH on Aquatic Organisms
Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.
Curated OER
It's All About the Roots
Students investigate the process of hydroponic agriculture. They grow beans in different hydroponic solutions, compare results and graph their observations.
Curated OER
Chemicals, Chemicals, Everywhere
Students divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling an...
Curated OER
The Circulatory System
Students follow the path of blood from its entrance into the right atrium of the heart until it leave through the aorta to the rest of the body. They study the heart's structure and how it pumps blood using the included activities. They...
Curated OER
What Do Bread and Beer Have in Common?
Students listen to an explanation of yeast cells and how they effect bread and beer. They discuss the ways alcohol affects the human body and participate in an indirect observation about cell respiration in yeast-molasses cultures.
Curated OER
Water Cycle Activity
Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...
Curated OER
Water Quality Testing
Student explore factors affecting ecosystems. They test local water samples for pH level. After creating a methodology for data collection, they collect data, compare results, and draw conclusions based upon results.
Curated OER
Mighty Oaks from Little Acorns
What does it mean to grow? To germinate? For the plan detailed here, class members investigate the growth process of an oak tree while focusing on the beginning stages of planting and germination. They plant seeds and record observations...
