More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

Equip pupils with tools to determine reaction rates as they explore conditions that cause a reaction to increase or decrease. They also discuss why this occurs and predict the next steps as they take part in a series of experiments. 

What do your vital signs tell your doctor? An engaging hands-on instructional activity has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the...

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

Both aerobic and anerobic respiration are introduced in this succinct PowerPoint. The chemical equations for both are included. The last slides give instructions for a lab activity in which pupils use a gas sensor to measure the...

What does a reaction rate tell you about your reaction? A thorough video lesson explains how to measure and read a reaction rate using two different methods. As the fifth installment in a 35-part chemistry series, the lesson uses...
