Capacity colours

In maths we are learning about capacity. In science we are learning about change. 

We did a fun problem solving activity where we had to think like mathematicians and scientists to mix two colours to make a new colour. We had to record and add together our amounts of different colours.

Ending Our Stories With A Question

We are learning to end our stories in different

Today we worked on using a question to end our stories. 

Ending with a question leaves the reader with something to think about.

Check out how these authors used questions to end their stories.

I like Spiderman because he shoots webs at bad guys. He can swing around with his special webs. I like watching the Spiderman movies. I wonder if there is going to be a new Spiderman movie?

At the A&P show I went on the ferris wheel with Mum. It went very fast. I held on for dear life! When the ferris wheel went round I could see everything because I was very high. I wonder if I will go there again?

When Rex, our dog, died he was only ten. When he died Daddy buried him. I loved Rex. I loved playing with him. He wasn't allowed inside. When we got home Rex barked, "Woof Woof." Will we get another dog?

Mixing acids with alkalines!

We are learning what happens when we mix acids with alkalines.

We know that an acid is something sour or bitter like vinegar or lemon juice. We know that an alkaline is not an acid.

We did an experiment with purple cabbage juice. We mixed the juice with some acids and alkalines to observe what chemical reaction would happen.

We learnt that
acid + acid = pink
acid + alkaline = blue or green

We poured boiling water onto the cabbage. We observed that straight away the water started to turn purple. We did one container with cold water and observed that the water didn't change colour. We concluded that the heat made the water change colour.

Izaiah mixing cabbage juice with lemon juice. Acid + acid = pink

Ciara mixing cabbage juice with Lux soap flakes. Acid + alkaline = blue or green.

Logan mixing cabbage juice with lemon juice. Acid + acid = pink

Ella mixing cabbage juice with cooking oil. We observed that the colour stayed purple and the cooking oil moved to the top of the cup. We concluded that because the oil is a fat and thicker than the cabbage juice it stops the juice from mixing. 

Acid + alkaline = blue or green

Acid + acid = pink

The coke changed only a little bit to a darker brown colour.

The milk changed to a light purple colour. We concluded that like the cooking oil the milk has lots of fat so the cabbage juice couldn't mix properly.

Chemical Reactions

We are learning about chemical reactions. We know that chemical reactions happen when things mix together to create something new.

We put vinegar in a bottle and half filled a balloon with baking soda and put it on top of the bottle. A chemical reaction happened!

Lots of children predicted that the balloon would explode!

Our Equipment: A balloon, a funnel, measuring cups, a small bottle, 1 cup of vinegar and some baking soda.

Pouring 1 cup of vinegar into the small bottle.

Kaedyn gently stretching the balloon.

Putting the balloon onto the funnel.

Carefully pouring baking soda into the balloon until it was half full.

Georgia lifting the balloon so the baking soda tips into the bottle.

A chemical reaction happened. 

The baking soda and vinegar created a chemical reaction. The acid (vinegar) mixed with the alkaline (baking soda) and created a gas (carbon dioxide). The gas moved up the bottle to make the balloon blow up.

Jack wondered what would happen if we added food colouring to the vinegar before we put the balloon with baking soda onto the bottle.

Adding food colouring did not stop the chemical reaction. We observed the only change was the bubbles and liquid were green.

Room 6 Scientists wrote about the experiment:

Room 6 are learning about science. We collected vinegar, a funnel, balloons, food colouring and newspaper. We poured the food colouring into the bottle of vinegar and put the balloon on the funnel and put baking soda in the funnel to drop in the balloon. We carefully took the balloon off and put it on the bottle of vinegar. We stretched the balloon out first. In the bottle it was really really really really bubbly! The bubbles were white. The food colouring was the colour green. We were all excited. Finally, all the air exploded in the balloon and blew the balloon up.

All of Room 6 have been learning to be Scientists. We did an experiment. First, we poured 1 cup of vinegar into a coke bottle. Second, we got a funnel then we stretched the balloon. We put the balloon onto the funnel. Slowly, we poured the baking soda in the funnel until the balloon was 1/2 full. I predicted that the balloon will pop. I observed that the balloon got bigger and bigger. What happened? Georgia tipped the balloon upside down and put the baking soda into the vinegar bottle then some baking soda got to the top then the balloon blew up!

The other day we did an experiment. First, we poured vinegar in the empty coke bottle. Next, we poured baking soda in the funnel and into the balloon. Then we poured the food colouring in the coke bottle. After that, we put a balloon on the bottle. The balloon will fill up with air and go fat! Get some newspaper but if you don't have newspaper do it outside. My hypothesis was: I predicted that it will explode onto the newspaper! I saw the vinegar mix with the food colouring that was green then the balloon filled up with air and nearly popped!

Football Skills

We are very lucky to have some clever football players visiting our school. Today, we had our first session learning how to dribble.

Check out the photos to see some awesome dribbling of the ball. We played a fun game called 'Body Parts'. Everyone has to dribble the ball and when the teacher calls body part everyone stops and then the teacher calls a body part name (head, bottom, elbow, nose, back or knee) and everyone has to quickly put that body part on the ball. It was heaps of fun and we learnt a lot about how to dribble a ball with the inside or the outside of our foot!

Fractions and Capacity

We are learning about fractions or parts of a whole.

We are also learning about capacity or the amount something can hold.

We joined Room 5 for some exciting maths outside. We had awesome fun working in groups for "capacity relays". We had to fill containers so they were completely full, 1/2 full, 1/4 full and 1/3 full. Check out the photos to see children filling and checking their containers and working together in a team to complete the capacity relays.

Thank you Mrs Hill and Room 5 - we had so much fun doing maths with you!
