[00:03.50]What Lucas Says
[00:06.87]Hi!I'm Lucas.I had fun with the experiments in this unit.Did you?
[00:15.23]I really liked the weird mud.I put a little cornstarch into a dish.
[00:22.07]Then I put a little water into the cornstarch.It looked like glue.
[00:28.45]I thought it was wet It was,but it wasn't
[00:34.40]When I touched it,it was dry!
[00:38.56]Many foods have cornstarch in them.
[00:42.63]So I guess you could eat the mud.
[00:46.39]But,would you chew it or drink it?What do you think?
[00:52.35]My teacher showed me the experiment with the water in the jar
[00:57.91]It was a full jar of water and thin piece of cardboard.
[01:04.08]I thought I knew what was going to happen:the water was going to spill.
[01:10.56]I was glad she was doing it over a sink
[01:15.10]But I guessed wrong.The water didn't spill.That surprised me!
[01:22.08]Did you try that experiment with wet cardboard?
[01:26.94]We did!Wet cardboard didn't hold the water.
[01:32.60]I think my very favourite experiment was the Mobius strip
[01:38.56]The Mobius strip was very easy to make,but it was very hard to understand!
[01:46.21]I'm holding a Mobius strip in my hands right now,and I still don't understand it!
[01:53.87]I'm glad Brian didn't try it with wet cardboard!
[01:59.33]Do you remember how to make a Mobius strip?
[02:04.79]Look in your Reader!
