|
| Educational standards to be addressed |
Physical Setting/ Chemistry Core Curriculum
- 4.2
Explain heat in terms of kinetic molecular theory. Qualitatively interpret heating and cooling curves in terms of changes in kinetic and potential energy, heat of vaporization, heat of fusion, and phase changes.
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 experiment, students will collect data and plot the heating curve of water. Two groups will use Sensor probes and transfer their data through wireless signal. Rest groups will do this experiment in this tradition way. Collect the data and plot the graph.
|
| 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.
