Mixing Substances

We are learning how to make concrete, how to observe and to experiment on it.

Next time I would like to try and make the top of the concrete more smooth, I would also like to make the sides way more smoother.

Oobleck or Putty for a foundation

What makes a good structure?

We compared Oobleck and Putty for a building. 

When I  touched the Oobleck my hand slowly sunk right down to the bottom of the container, when I touched the Putty my hand pressed down through it. 

When I squeezed the Oobleck it felt like hard playdoh, when I squeezed the Putty it looked for a way out of my hand and oozed out. 

When I poured the Oobleck it looked like rain drops dripping down windows, when I poured the Putty it was moving to the other end of the container and it was moving ten times slower than a snail.

When I punched the Oobleck it did nothing and kind of hurt my hand, when I punched the Putty it just stuck to my hand.

When I  pressed the Oobleck into a ball it crumbled, when I pressed the Putty into a ball it did nothing.

 and what happened when we spread it out.
