Changing states of Matter What you need to see dancing worms: Baking Soda Vinegar Gummi Worms Warm water
Today we looked at changing states of matter. We noticed that powered baking soda was the solid and when we added water it turned into a liquid. We let the gummi worms soak in the baking soda. Then we drained the baking soda water off the worms and we put the worms into a cup of vinegar. We then saw another change - we saw a gas appear from the fizz!
Predictions: Kayley - Its going to start dancing Hannah - They are going to wriggle Naesha - They are going to stick together and dance together Cherize - They are going to look like a wriggly worm Ben - They are going to wiggle and going to jump up What do you think is going to happen when we put the gummi worms into the vinegar? Caleb - They are going to explode! Shivali - The worms are going to go up Millar - The worms are going to start dancing and jump out and start walking like humans! We added the gummi worms and this is what we saw... "I can see fizzing" "I can see bubbles" "I can see gas coming out and it burnt my eyes" "It looks like sprite!" So what really happened? The worms did not move like we expected :( They did float around a little bit, but they did not dance like we predicted! Maybe you could try this one at home with your family? Takes some pictures so we can see!!

As part of Home Fun this week, children of Room 16 are challenged to bring in something healthy for brain food this week. Our healthy snacks have been steadily improving which is fabulous to see!
We wanted to know if Coca-Cola was a healthy drink option... What we discovered will shock you!
Look at the images below, we measured out how many teaspoons of sugar went into a can of coke, a small bottle of coke and a family sized bottle of coke. Each plastic cup contains the amount of sugar that goes into each size. As a class we were amazed at the huge amount of sugar, that can't be good for us!
This week we read about the Gingerbread Man. When the Gingerbread man got to the river where the Fox was waiting, I had the children think about what they might be thinking using the picture below as a prompt.
We all agreed that the Fox was thinking of a cunning plan to eat the gingerbread man and the gingerbread man simply thought the Fox was being a friend by helping him across the water.
We then discussed what would happen if the gingerbread man had to cross the river on his own... what would happen to him? We then came up with an experiment to test out our ideas using a ginger nut, a cup of water and some M&M's (these were our gingerbread mans buttons).
We learnt how to 'predict'. A lot of us predicted that the ginger nut would sink in the cup of water... but in fact it floated! It was only until we moved the cup that the ginger nut sank.
It was also very interesting to see how the colour on the M&M's came away and changed the colour of the water... We were all super shocked to see how much food colouring goes into each M&M. Not so good for our tummies!
The floating ginger nut
Here is Hannah's prediction she wrote up herself!
The ginger nut experiment
My prediction was right. I was super shocked that the ginger nut floated on the water because I thought the water was going to suck up the ginger nut biscuit and make it smaller. I thought it would disintegrate.
