M & M's experiment

On Tuesday in the afternoon we did a science experiment  it was on m & ms  now we haft to do the instructions first we got 4 different coloured m & ms now we haft to get a petri dish then we put the m & ms in the petri dish then we got a bit of water now Mrs Cheeseman will pour the water for us. Then we had to wait for 10 minutes until the colours got sucked off the m & ms we figured out that on the top that it was clear on the bottom it had  lots of colour  like a rainbow.

caution DO NOT KNOCK THE TABLE because the colours will go brown and white sugar will float on the top of the water. And if the sugar comes off you will be able to see the yummy chocolate but Toby’s group didn’t knock there petri dish so they got a super coloured water the blue joined with the yellow and made a green then the blue and red made purple also the yellow and red made orange but then the brown didn’t make any colours with the other colours.

This is the instructions;
1 get a petri dish;
2 get 4 different colours of m & ms;
3 poor a small amount of water in the petri dish;
4 do not knock the table;
5 see what happens;

prediction what we think will happen; the colour will go away; 2 the colour in the water will change rainbow; 3 the m & m’s  will float like paper; 4 the m & m’s will go white ;

observation what we saw happening; 1 the colour is combining  with the other colours; 2 the water on the top is clear on the bottom it is not clear because the m & m’s colour is on the bottom;

conclusion why
we think this happened; 1 if  you knock it you will make the water move and make it all brown; 2 the colours where on a shield of suger but the water dissolve the colour 1 shield down now the m & ms are white but water now is dissolve the suger now theres a chocolate shield now but the water strikes back but the chocolate is already wet so the water makes it break.

The amazing EGGsperiment

Room 22 did an excellent science experiment and it was called the amazing EGGsperiment. First we boiled 4 smelly eggs, Miss Cheeseman hates eggs! We had to peel the shell off the eggs, it was a messy job but we still did it, one was a disaster but it worked out fine. We had to try and get a boiled egg into a glass jar that was too small for the egg but without breaking it. It was time to burn the paper, Miss Cheeseman put the rustling paper in the jar then Henderson swiftly put the egg on the jar. But the paper kept on burning out, so then Kiana came up with the idea to use newspaper and it worked in the big jar. We tried again in the little jar but it didn't work but the egg that time got halfway through though. We were very pleased that one of them worked.We learnt that the egg slides down because fire needs oxygen and when we put the egg on top it blocked the oxygen and the air outside the jar pushes the egg into the jar.
Hopefully room 22 had a great time.                       By Kiana and Chantelle

                                      

Swirly Milk

Last week we did a science experiment called Swirly Milk. First you put milk in a big bowl, Secondly you put in four different colours in four spaces and Thirdly you put a little bit of dishwashing liquid in the middle. Once you have done that then because of the dishwashing liquid it doesn't stay in it's own territory it spreads and makes a spiral with all the different colours.It does it completely on it's own - like a volcano

The peppery skin!

BEFORE

Yesterday Miss Cheeseman found  an experiment. Then she decided room 22 should do the experiment we had a bit of help from Miss Cheeseman. It was called the peppery skin. We found out that water has skin sometimes you can't see it.
This is what we did: we put water into a bowl then we put loads of pepper in the bowl .After that we put a drop of dish washing liquid then the pepper got scared and ran away to the edge because water has a skin layer and when you put pepper and a drop of dish washing liqud the skin layer breaks.

Experiments with Natasha!!!

 (The third  Experiment when 2 - liquids turn into a solid which is called precipitation reaction )

 On Wednesday, a scientist named Natasha came and showed us 3 experiments about acids and bases. The first experiment was putting a 10 cent coin in lemon juice or vinegar.

Method :

1. One person from each group came and got a cup of lemon juice or vinegar and a 10 cent coin.
2. We put it on the table and put the 10 cent coin in.
3. We watched to see what would happen.

I learnt :

1. That fruits like lemon, orange and grapefruit are a citric acid.
2. That lemon cleaned the lemon because lemon is a citric acid and the coin is a base.

Results :
The coin got clean because the lemon juice it is a citric acid and it is sour.



The second experiment was putting magnesium in hydrochloric acid or for short you can call it HCI.

Method :

1. A different person from each group came up and got a cup of HCI and a small piece of magnesium.
2. We put the cup on the table and put the magnesium in the cup.
3. We watched to see what happened.

I learnt :

1. That it took about 1 minute to start fizzing and bubbling.
2. About 5 mins later it started dissolving into the HCI.
3. Later on it was gone.

The magnesium dissolved into the HCI so about 4 mins later it was gone.


The third experiment was a blue liquid and a clear liquid and put them together.
Method :

1. A different person from each group came and got a cup of clear liquid and put it on the table.
2. We all waited for Natasha to pour some blue liquid into the cup of the clear liquid.
3. We waited to see what would happen.

I learnt :

1. That 2 - liquids make a solid.

Results :
The blue liquid and the clear liquid made a blue and hard solid which is called precipitation reaction.


Note :


The words that are blue are scientific words.

Science Ignition day!

Today it is Sience Ignition day!!  The whole entire school did it but some of the teachers only went to the other classes not even doing expiramints with all the other classes. My class rm 22 did the Foaming snake, Lava lamp, Rainbow tube, Slime, Exploding tubes, Snow and also my favourite Candy mountain, Candy mountain is my favourite because I really love candy floss! The activity that I liked the least was the Slime because it was not that interesting because it is something that I commonly do.  As soon as I heard that we were doing Science Ignition I almost SCREAMED!!! I was really super excited that I could not wait till we did it.  I already did block 1 now we are still on block 2. We are waiting for our turn in the hall so we have to be really paitent. Ok now we are in the hall and there is music playing as quiet as a normal guitar playing jazz music. We are watching Science in a van. The name os the two people that work in Science in a van's name's are Emily and Alan. First we were talking about the force and now we are talking about gravity and how it works. Now we are talking about something super super super easy. Emily needed 2 assitants, Emily is now makishowing us what's in the bag.ng them 2 to lift up 2 shopping bags. Now Emily is showing us all the stuff that were in the bags and the assistant picked it up. well I am going to stop talking about this or else this will become to long with all the other stuff I am going to tell you. Ok now it is afternoon. Miss Cheeseman  said that a scientist might come in our classroom to tell us some more stuff and do some more experiments so stay on the blog tommorrow.
