This is an extension of our phases of matter work. OOBLECK is special and can best be explored at home with your family. Perhaps you will even take a few pictures of your family's encounter with this non-Newtonian fluid.
B day should try to have it finished by Friday or Tuesday (since it just got posted today.
A day should have it finished by Monday.
You may present your findings via the analysis questions and answers in your ISN or you may make a very short electronic presentation that you can send via e-mail to smithp8@duvalschools.org or bring it on your thumb drive (flash drive, stick whatever you call it). If a family chooses for the child not to participate, then please write me a note and let me know why. I understand that there may be allergens to be considered.
Home Learning: Phases of Matter- OOBLECK
1.
Combine 120 ml of water to 180 – 240g of cornstarch
in a large container. ( Water can be
measured in ml, and 1 ml = 1g for water.
2.
Mix water and cornstarch together using a spoon or
your hands. It can be messy.
3.
Place the mixture on paper plate. This will allow
you to move the oobleck around as you invert the plate. Play with it. Does it run? Splat it with a
spoon. What happens?
