Curated OER
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
Carbon Dioxide Heats It Up
Young scholars design an investigation to test whether vegetation in an area helps regulate the ambient air temperature. They make comparisons between the investigation and global changes in climate. In groups, they present their...
Curated OER
Cell Energy-Colorful Respiration
Students examine the acid-base indicator, bromthymol blue (BTB), and what happens to it when you blow air into it or add plants and snails. Through an experiment, they test three different setups of BTB and record the color changes that...

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.
Curated OER
Mycorrhiza
Learners examine the symbiotic relationship between fungus and plants. In this ecosystem lesson students complete several mycorrhiza experiments.
Curated OER
Algae Experiments
Students describe the characteristics of algae. In this biology instructional activity, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.
Curated OER
Mold
Students explore mold, the different types and the health risks that they pose. In this mycelium lesson students grow different molds and see which type of foods mold the fastest.
