							             Grade 9 Chemistry - Writing a Lab Report
Actvity #1 : Making Gak                             Name:_________________
Materials :
   1. Make a list of the materials and equipment you used to make Gak

Procedure :
   2. Write down the steps required to make Gak (In the same way a recipie is written).
      You should have at least 4 steps

Observations :
   3. What are the properties of the glue, water and Borax at the beginning of the
      activity, before you mix them?

   4. What are the properties of the glue, water and Borax at the end of the activity,
      after you’ve mixed them?

   5. Make a list of 6 or 7 properties you observed while you were experimenting with
      Gak

   6. Draw 4 or 5 pictures to demonstrate interesting observations you made while you
      were experimenting with Gak.

Conclusions :
   7. Why is this experiment a good example of chemistry at work?

   8. Why do you think Gak is rubbery?

Exploration :
   9. Find a definition for “polymer”

   10. How is Gak a polymer?

   11. What are other examples of polymers?

   12. Make a list of 10 activities or situations in the world around you where Chemistry
       and chemical reactions are used.
