A terrific clip about persistence!
Here's a wonderful video clip we enjoyed today all about not giving up. The class was so enthralled they cheered at the end!

Dancing Raisins!
Here's a fun experiment that you can try at home!
You need:
Lemonade
Raisins
What to do:
Pour some lemonade in a cup and then add a few raisins.
What's happening:
Raisins are denser than the lemonade, so initially they sink to the bottom of the glass. The carbonated soft drink releases carbon dioxide bubbles. When these bubbles stick to the rough surface of a raisin, the raisin is lifted because of the increase in buoyancy. When the raisin reaches the surface, the bubbles pop, and the carbon dioxide gas escapes into the air. This causes the raisin to lose buoyancy and sink. This rising and sinking of the raisins continues until most of the carbon dioxide has escaped, and the lemonade goes flat. Furthermore, with time the raisin gets soggy and becomes too heavy to rise to the surface.

ESR Scientists
Today we had some Soil Scientists come in and talk to us about Soil.
There are 3 main types - Clay, Loam, and Sand. We learnt how water gets through sand much easier than clay and we also tested different types of soil - making worms out of clay based soil.

Science Week! - Surface Tension
Looking at Surface tension has been fascinating. Some great writing has come from this as well - will put that up soon. Here is an experiment we did to help us understand Surface tension more. - How many drops of water could fit on a coin?

Week 1 on the Bike Track
Well, at the start of this week we had 10 out of 27 who could not ride a bike - yikes!
I am so proud of Room 4 though. 2 band aids and 1 ice pack (sorry Barbara!) after we are down to 1 to yet conquer riding a bike. Way to go guys!!
