|
| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
Based on their observation, by the end of the period, students should be able to explain that:
- The se of CO2 level to demonstrate the rate of reaction.
- The use of collision theory to explain how increasing particle size, temperature, concentration will increase the rate of reaction.
Higher level thinking:
- Explain how using wireless devices to measure the CO2 emission rate may be applied in other fields/research.

| Short Description and Walk-through of the experiment |
Based on the class size, students will be divided in groups of 4. Each group will work on their part of the experiment. Toward the end of the period, students will present their experiment data and see how this wireless device may help us collect and transfer data.
- Group 1 - 2: Students will collect the rate of reaction at cold and hot temperatures and explain how temperature affects the rate of reaction.
- Group 3 - 4: Students will collect the rate of reaction at large and small surface area and explain how surface area affects the rate of reaction.
- Group 5 - 6: Students will collect the rate of reaction at low and high concentration and explain how concentration affects the rate of reaction.
- Group 7 - 8: Students will use the temperature probe and CO2 sensor to collect data and explain how temperature affects the rate of reaction.
