All the POI had packing peanuts at their work station. [Mark your POI Data Sheet accordingly.]
It appears that Hyper Harry was experimenting with these packing peanuts to determine what was the best solvent to use on them. The class will now participate together in a group activity and share results as you model the experiments that Hyper Harry was doing. You will each do the 5 experiments and then share your data. (5 experiments: hot water, room temperature water, cold water, acid (vinegar), and shredded peanut)
Ruler - measuring in cm
6 packing peanuts approximately all the same size
9 clear plastic cups, 2 styrofoam cups, and 1 glass beaker for measuring
plastic model guide for set-up of experiment
paper plate to put your wet peanuts on to measure
Timer to set for 10 minutes (use your chromebook)
Shared class data sheet (link in your Google Classroom to a Google Sheet)
Solvents: hot, cold, and room temperature water, acid (vinegar)
Procedure:
1) Use the glass beaker to measure 40 ml of room temperature water from the milk jug. Take 4 of the plastic cups and put 40 ml of room temperature water into each of them. Take 1 of the styrofoam cups and put 40 ml of room temperature water in it. These will be used as a “weight” to hold the packing peanut down in the testing cup so it will be totally submerged in the solution.
2) Use the glass beaker to smash 5 packing peanuts. After the peanut is smashed, measure the length and width of each of the packing peanuts in centimeters (cm) and put the measurements in the class shared data worksheet. Be sure to only put in the numbers (do not put in cm or words as it will block the equations from working). All measurements have to be in decimal format!
3) Class shared data Google Sheet - there is a separate page for each of the 5 experiments. Please be careful and put your data on the correct page. The 6th page will automatically total the data and fill the graph. You will need to go to this page to answer questions after the data is collected for your class.
4) Take one of the smashed packing peanuts and shred it up into small pieces. You can tear it with your fingers or use scissors to cut it up. Put all the pieces into one of the dry plastic cups. Be sure to not lose any of the pieces.
5) You want all of your tests to run at the same time so you only have to wait 10 minutes for all of them to be completed.
6) Use the glass beaker to measure 40 ml of each of the solutions for the 4 clear plastic testing cups (cold, room temperature, vinegar, and one more room temperature for the shredded peanut). Use the glass beaker last and measure 40 ml of hot water and place it in the styrofoam cup.
7)Take temperatures in Celisus of cold, hot, and room temperature waters and vinegar. Take pH reading of water (will be the same for all the waters) and vinegar. Enter information into your shared class table. Again, do not enter any alpha characters, only numbers.
8) Put one packing peanut into each of the 5 testing cups (4 whole ones & 1 shredded)
9) Start the timer for 10 minutes
10) Place your prepared “weights” in each of the cups so the packing peanut is completely submerged. No stirring.
11) While you are waiting, you can return to the Final and work ahead answering questions
12) At the end of the 10 minutes. Remove the weights and then the remains of the packing peanuts. Use the paper plate to put your pieces on so you won't have water all over your table. Measure their length and width and enter data into the class worksheet. For the shredded peanut, squish all the pieces together as much as you can and then measure it.
>empty dry plastic cup you originally put the shredded peanut in
> The water used in the cups for weights is clean - you can carefully pour the water back into the milk jug and dry the cups with the rag - put dry cups back into your table tub
> The cups with peanuts & liquid - pour contents into one tub and then put all the empty cups into the other container marked for used cups on the back counter
Trash Can: the remains of the peanuts and paper plates and any paper toweling used for clean-up
