The 3rd Experiment on Wednesday

The 3rd experiment we did on Wednesday involved making a balloon rocket.

This was the most exciting. We tried with different shaped balloons, both inside and outside.

We even tried to make our rocket go up a hill.

Ask your child to explain what we did. It was lots of fun!

The second experiment on Wednedsday

In the second experiment, yeast was added to warm water which had a little bit of sugar in it.

The balloon expanded a little bit but we will repeat this experiment as we discovered that the yeast was 3 years old!

Experiments using balloons

On Wednesday the 4th of July we did 3 experiments using balloons.

The first was called building a fizz inflator and used vinegar and baking soda.

This is what happened because carbon dioxide was created when the vinegar and soda mixed together.

Can you get an egg in a bottle?

Can you get an egg into a bottle even when it seems not to fit?

Well the kids in Room 10 tried.

Mrs Nicholson thought she had found the perfect container but after she had taken the shell off the egg it just fell straight into the jar.

So that was no good.

Next she found a drink bottle.

The bottle had to sit in hot water for five minutes.

Then the bottle was moved to sit in a bag of ice. The egg wasa placed on top of the bottle, pointy end down.

As we watched we wondered what would happen.

Titan thought the ice would melt. Six kids agreed with him.

Lilly and Rhys thought the ice would go misty and steamy.

Michael thought that the egg would get stuck on top and it definitely did but then something else happened.

Kyle thought the egg would pop up.

Desiree thought the egg would go through the hole and fall into the bottle. Ten kids agreed with her.

Aidan thought the egg would turn blue.

Sophie thought the egg might freeze. Four other kids thought this might happen too.

What happened and Why?

The egg did fall into the bottle because the air pressure inside the bottle changed. We were all really amazed!

Learning about ice

Cutie Fingers!
Today we did 2 more great experiments both involving ice.

The first involved a glove which had been filled with blue coloured water and then left in the freezer until it changed from a solid into a liquid.

We called it Cutie fingers.

After some discussion Lilly predicted that the fingers would melt first because they are thinner.

Everyone agreed with her.

What happened?

The fingers did melt first and went all floppy.

Second Milk Experiment

The second experiment involved tea, lemonade and orange juice.
All of these were added to milk and then we had to wait one minute to give time for a reaction.

Tea and Milk
Brianna and Grace thought the colour would change. Three kids agreed with them.
Kyle thought bubbles would form. Four kids agreed with him.
Hannah thought they would mix togethe. Three kids agreed with her.
Sophie thought they would explode. Thirteen kids agreed with her.
Lilly thought the mixture would turn darker and two kids agreed with her.

What happened?
They did mix together. It looked like milky coffee.

Lemonade and Milk
Michael thought bubbles would form. Six kids agreed with him.
Desiree and Kyle thought it might explode. Twelve kids agreed with them.
Brianna thought nothing would happen and three kids agreed with her.
Mayana thought steam might rise and four kids agreed with her.

What happened?
The protein in the milk curdled because the lemonade changed the pH levels in the milk.

Orange Juice and Milk
Alicia thought they would mix together and four kids agreed with her.
Lilly thought the liquid would turn orangey brown.
Liam thought it would turn ice like. Eleven kids agreed with him.
Jade thought they would bubble and five kids agreed with her.
Karen thought the mixture would turn a lighter colour and four kids agreed with her.

What happened?
The protein in the milk curdled because the orange juice changed the pH levels in the milk.

The orange juice and lemonade had a similiar effect. The tea didn't make the milk curdle because it did not change the pH level of the milk.

Welcome back to Term 2

A big hello to you all and hoping you have enjoyed the holidays.

This week is Science week so to celebrate this we are going to spend our Topic time discovering.

Today we did two experiments involving milk.

The first involved milk, food colouring and washing up liquid.

Liam predicted bubbles would form. Six kids agreed with him.

Ryan and Lilly predicted the colours would change. Six kids also agreed with them.

Aidan thought the milk might evapourate. Two kids agreed with him.

Someone thought nothing would happen.

Ryan thought the colours would mix together and ten kids thought he was right.

This is what actually happened.
