Obelix - Weird Science Goop!
On Friday, Learning Hub 3 had their very own assembly. We sang a song that Hub 3 created with a little bit of help from Miss Smerdon. We did lots of awesome stuff like teaching how to make music with graphic notation and being mad scientists. You know what, it was really funny because we chose people to be to be a body and then we chose other people to be the arms. The body people put their arms behind their backs while the people who were the arms slipped their hands through and pretended to be the same person. The arms did all sorts of wacky things like feeding the body sandwiches and shapes and answered science questions. We were really proud of our assembly because we did almost everything by ourselves.
In the second block, we went outside and made obelix with Miss Holland. Obelix is a type of goop, made with cornflour, water and just to make it more fun, some food colouring (see how to make it here, it's pretty easy... http://sciencesquad.questacon.edu.au/activities/cornflour_slime.html) We mixed it together in our groups of 4 to 6 (which is called collaborating!) and had lots of fun and got messy!
The goop felt weird. It felt hard when you started to roll it around but when you stopped moving it, it fell through your fingers like slime. Very creepy! When we went to pick it up the slime parted almost like runny plastic might and when we punched it the slime was quite hard and you didn't get much on your fingers. It was like punching a tree trunk but a bit gooier.
Afterwards we talked about how things can be in different states. They're either solid, liquid or gas. This goop was strange because it was liquid and solid at the same time! Now we're going to find out why it does what it does because we haven't seen anything like this before.
