|
| Educational standards to be addressed |
Physical Setting/ Chemistry Core Curriculum
- 4.1
Observe and describe transmission of various forms of energy. Distinguish between endothermic and exothermic reactions, using energy terms in a reaction equation, ∆H, potential energy diagrams, or experimental data.
Common Core ELA/Writing/Math Standards
- CCSS.ELA-Literacy.RST.11-12.8
Evaluate the hypotheses, data, analysis, and conclusions in a science or technical text, verifying the data when possible and corroborating or challenging conclusions with other sources of information.
|
| COSMOS concepts to be used for the lab |
Real-time data, Chronograph formatting of results allow students to visualize the data.
|
| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
They will develop a number of research-related skills (i.e., assessing Chronograf results and problem-solving experiments).
|
| Short Description and Walk-through of the experiment |
In this lesson, students will use COSMOS toolkit to test how temperature difference in endothermic and exothermic reactions. They will compare the traditional method of measuring temperature change versus the measuring temperature change with COSMOS toolkit.
|
| Testbed mapping of the experiment |
Testbed nodes-sensors can provide real-time data on temperature, humidity, and CO2 and help manage certain fragile or threatened ecosystems.
