Makeup Lab: INFORMING THE FARMERS
If you missed the lab activity on January 22 or 23 then you will need to complete this alternative assessment.
Use the rubric and directions that are posted on the blog and were handed out in class.
Cut up a potato into strips like “French fries”. Put into cold water.
Prepare a salt solution in a bowl. Measure how much salt you put in and how much water. Use volume to determine the ration of the salt to water. Then make another solution with double the amount of salt, but the same amount of water.
Find a way to measure the flexibility of the potato sticks. Put some the first solution, some in the second solution. Don’t forget your control.
Check the flexibility after treating the sticks. Make observations and record them in your ISN.
Use a sheet of carbon paper (available in class) or a large piece of paper to prepare your V report.
Turn it in ASAP.
