Carbon Dioxide
Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.
Curated OER
Alternative Energy
Students discover the different alternative fuel sources. In this biology lesson, students identify the different stages of the carbon cycle. They explain the pros and cons of using alternative energy.

Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...
Curated OER
Stomata: Microscopic Openings that Let Plants Breathe
Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.
Curated OER
Introduction to Dissolved Oxygen and Demonstration of a Simple Test Procedure
Students explain the importance of dissolved oxygen in water ecosystems. They describe the aquatic oxygen cycle and the effect of water pollution on oxygen. They make observations, collect data and draw a conclusion.
