Objective:  Endothermic and exothermic chemical reaction data collection lab. 
Purpose:  Collect data to prove that chemical reactions are either endothermic or exothermic.


Agenda:

1. Lab safety
2. Collect data
3. Graph your results
4. Analyze your results
5. Final Clean up

How to work collaboratively:

1.  Each group will assign tasks (each student will have at least one task)

• Time Keeper (make sure you know how to use the times)
• Experiment Lead (mix chemicals and call out temperature every minute)
• Recorder of Data (write down the temperature at each minute intervals; share with the entire group)
• Safety Officer (ensure equipment used safely, area is clean at all times, and do a final clean up when lab is over)Objective:  Endothermic and exothermic chemical reaction data collection lab.

During the Data Collection:  

1. Record initial temperature

2. Time your experiment for 3 minutes, taking temperature readings at 1, 2, 3 minute mark

3.  Stir gently during the chemical reaction

4. Raise your hand to signal that you are ready for more chemicals

5.  Report any accidents

How to Graph your results:
