NYS Core Curriculum
- Key Idea 3
The observations made while testing proposed explanations, when analyzed using conventional and invented methods, provide new insights into natural phenomena.
- Key Idea 5
Organisms maintain a dynamic equilibrium that sustains life.
NGSS
- HS-LS1-2
Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
- HS-LS1-7
Use a model to illustrate that aerobic cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy

| COSMOS concepts to be used for the lab |
Real-time data, Chronograph formatting of results allow students to better understand how a rise in temperature (to an extent) leads to an increased respiration rate through accelerated collisions between molecules.
|
| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
It develops a number of research-related skills (i.e. assess data and problem solve experiments), as well as understand how organisms interdependent on their environment.
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 |
- Armadillidium vulgare habitat setup:
- Based on this passage and the information provided in the resources above students should be able to construct a habitat for this detritivore.
- Students add up the total number of Pill bugs over the 5 min observational period for this experiment, the team that records the highest number of Pill bug visits (100% preference = 100 if you are using 10 individuals).
- Students should share out their recommendations for optimal Pill bug habitat; there will be a final vote will be taken.
- Temperature’s effect on cellular respiration:
- Students are assigned a temperature for this portion of the project (4C, 22C, 37C).
- Students attach the temperature and carbon dioxide (CO2) sensors to the wall of their cups/containers
- Final Report: temperature’s influence on pill bug respiration

| 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.
