Research Question: To discover what phase of matter does cornstarch and water form.

Hypothesis: I think that the mystery substance and water will form a solid/liquid becauseā€¦

rocedure:
1. collect all the required materials
2. measure the correct amount of cornstarch (300g)using triple beam balance
3. measure correct amount of water (200mL) using graduated cylinder
4. slowly mix the water with the cornstarch, using hands to mix
5. after substance is created, conduct the different tests
6. record your observations in the table
7. make conclusion whether test means substance is solid or liquid

Test
Observation
Solid
Liquid
Poke Test (fast)
Quickly poke finger into substance



Poke Test (Slow)
Slowly poke finger into substance



Finger Pull Test I
(when finger is in substance, quickly try and pull it out)



Finger Pull Test II
(when finger is in substance, slowly try and pull it out)



Squeeze Test
Squeeze a small amount of substance in your hand



Drop Test
Drop a fist full of substance onto lab table



Pour Test
Try and pour the substance from beaker onto lab table



Container Test
Try and pour substance from one container to another



Pencil test
Hit pencil hard on substance, then drop pencil onto substance



Your Own Test




Conclusion: What happened??

Based on your findings from the experiments explain whether the substance is a solid or a liquid. Use your results to help in your decision: You can use diagrams to help explain your decision:
Go to http://www.wisegeek.com/what-is-a-non-newtonian-fluid.htm and in your own words explain what the substance actually is. Also, what could a possible future use of the substance be?
