Sprinkler Experiment by Grace

Here we are warming up our brains playing challenging games against people from other rooms. 





Grace brought along a water bottle fitted with a straw for her Sprinkler Experiment.





She had cold water inside the bottle and then sat that bottle inside a jug of boiling water.





Grace hypothesised that as the pressure inside the bottle heats up as the water gets warmer... the water will come out the top of the straw like a sprinkler.





When she first did the experiment nothing happened but Aliyah told us all to have some patience. As we waited the cold water inside the bottle slowly heated up and the water started to drip out of the top of the straw. 





We kept waiting and watching... it didn't actually start to spray out like a sprinkler but the longer we waited the more the drips speed up.





We think the heat acted like a catalyst to speed up the drips. The hotter the water in the jug the faster it would heat the cold water in the bottle.


Thanks Grace. Mrs Maw has been so impressed with the way everyone has self managed this activity.

The only person we are waiting for now is Blake. He will bring his experiment ( or a video of it) with him to TAG in Term 4.

Aaliyah's Water in a Bag Experiment

Aaliyah brought along an experiment that used a plastic bag filled with water and some pencils.


Her hypothesis was that if she poked pencils through the bag no water would leak out because there would be friction around the holes which would seal them around the pencil.

She did the experiment and only one hole leaked a tiny bit.







An excellent experiment Aaliyah!

We are looking forward to Blake and Grace's experiment next time!

One experiment and one scientist - Thanks Margo and Georgia !

 Margo brought along an experiment with lots of scientific equipment she could teach us the names to.

She had a beaker, a test tube, a pipette, a drip tray, a scoop.

Her hypothesis was that if she combined vinegar and baking soda there would be a reaction ( explosion) and gas and liquid would bubble up out of the test tube over into the drip tray.

She was right!

She repeated the experiment in a larger container with more baking soda and vinegar and she hypothesised that the reaction would also be BIGGER - she was right again.

We talked about how after an experiment the things in the experiment have changed and aren't still vinegar and baking soda... so you couldn't reuse the vinegar and pour it in with the unused stuff or it would not work.

We also talked about some ways to speed up an experiment - stirring, shaking, heating up or adding a catalyst because Margo tried stirring the leftovers to make it speed up and it did work.


Wow that was lots of science words!









Georgia has studied a famous scientist Rosalind Rosevelt.


Rosalind took the first photo of DNA  which showed its structure and found out all about it.


Georgia had prepared an amazing powerpoint which she had timed exactly to her words.

She also had colour photocopies of the structure of DNA for us to look at up close.

We thought we learned flash words with Margo... then Georgia taught us Deoxyribonucleic acid!







Bradley also tried his experiment at home before he shared it with us.

Here are his results

Our Inquiry Questions now we have finished our experiments.

 

Darcy 

Question 1-  Why is the moon sometimes out in the daytime?

Answer

The moon is visible in daylight almost always but we just don't look or it is behind clouds.

The moon and the sun are only opposite each other in the sky one day a month - on a full moon!

On this day the sun is rising just as the sun is setting. That is not the case every other day of that month.

Angus 

Question 1- Why do Zebra have black and white stripes? What good is that for camouflage?

I found out that zebra can camouflage unto the dry grass and the predators are colour blind so it will look black and white. they don't attack because they think that it is some sort of big animal. Zebra stripes can scare away flies.


Logan 

Question 1- Why do Chameleons need so many different colour changes for camouflage?

Chameleons do use camouflage the ability to blend int their surroundings to hide from predators such as snakes and birds, their natural colour is greenish brown to blend in.

She might also tune brown or white to indicate that she is not in the mood. 

The brown colour can mean lots of things. On reason why a chameleon turns brown is that it is depressed.

Chameleons are famous for their quick colour changing ability. It is a common mistake for people to think this is for camouflage but it can also be to show moods. 

Bradley 

Question1 - How many stars are in the Milky Way ? 

Answer - 100 Billion stars

 Question 2 - Mrs Maw says...How do they know that Bradley ?

Answer - We know it is 100 billion starts in the Milky Way because they found out that red, white and blue stars give give off different amounts of light. By measuring that starlight specifically its colour and brightness astronomers can estimate how many stars our galaxies hold.

Bradley 

3  - How many solar systems are in a galaxy ?

Our Planetary System is the only one official solar system but astronomers have discovered more than 3200 stars with planets orbiting them in our galaxy.


Noah - What were the first stars born in the whole galaxy? The first stars formed when the universe was about 100 million years old. The formation of the first galaxy . These stars were called Population 3 stars  and we don't know why. They have already classed the stars of the Milky Way as Population 2 stars. 

Thomas - What are the animals that can see colours that humans can't and what is it that they can see? How do we know that they can see them?


Dogs can only see the difference in light. Dogs can only pick up blue and yellow. There is 50000 different types of each colour which makes 10,000 altogether. Dogs can see in the dark better than their humans. 

Humans have 3 types of cones - red blue and green. Both the red and blue cones overlap, together with the rods which perceive black and white. This allows humans to see millions of colours.  However some animals have cones that are able to detect ultra violet wavelengths and others are able to detect infra red wavelengths.

Chameleons can see ultraviolet light. Additionally, some birds have cones other than those preciously mentioned meaning that they can see colours we cannot.
