Keep it in mind that it is Wednesday, ie. Short day -- classes are 40 minutes long At a minimum, it will take 20 minutes to complete the trials

3. Procedure
Obtain one piece of 2-4 different brands of gum from me. Each partner is responsible for one brand
Use the gum’s wrapper as a weighing boat so it doesn’t touch the scale
Unwrap your sticks of gum (make sure you wash your hands first before touching the gum). Indicate the gum brand name in the data table
Place the wrapper on the electronic balance and push the “Zero” or “Tare” button. The reading on the scale should read “0.00g”.
You will need to do this each time you weigh your gum
Place your piece of unwrapped gum on the wrapper and record the mass in the data table (include units).
Remove the gum and wrapper from the balance.
Place gum in your mouth and chew for TWO minutes

4. Procedure Place gum in your mouth and chew for TWO minutes
When the 2 minutes is up, place the gum between your teeth and suck it dry. (Again, think about why you want the gum to be dry?)
Repeat steps 4-6 in order to determine its new mass
Repeat until you have made 11 observations
This means it goes till the 20 minutes mark
Mark down which time period the gum lost its flavor during
Please throw gum wrapper away after your last observation
Make sure to record the masses of the other group members
Find the change in mass and the percentage of the change in mass
Create 2 graphs
Answer questions from Google Classroom

5. Things to keep in mind!!
DO NOT create your table first. You will run out of time. Take your first mass, then chew, then create your table
I recommend staggering when you start chewing to every 30 seconds. That way everybody isn’t trying to use the scale at the same time
Each time you weigh it, use the same wrapper
Use timers on your phones.
Focus on getting data for YOUR gum first, then you can copy down the data from others
If you don’t want to chew gum, you don’t have to
Please, Please, Please, be careful not to get gum everywhere. Please!
