Silly Science incursion

Today was our silly science incursion. We learnt a lot of new things for our science education.


It was sticky, it was gooey, it was slime. In our incursion we made slime, we got to take the slime home after we made it. Did you know that nonutoniaviscoelastic fluid means slime?image

POP! The rocket shot out of the beaker. We found out that if you mix bi-carb soda and vinegar together, shake it and put a small rocket on top, the rocket will shoot up.


CLICK! The magnets clicked together. It was time to fish for magnets! We were aloud to catch five fish and then we had to move to the next rotation.


SNAP! The magnets snapped together as we built the tunnels to pull the metal through. As we pulled the magnets through we wondered what mak s the metal attract to the magnets.


Drip, drip, drip, how many pencils can you stick through the bag full of water with out it leaking? 1,2,3, we got a lot.

It was so much fun!!😊

Science experiment

We are learning about all things science this term and today we decided to do an experiment to see what happened when we mixed oil and water. The first experiment was a bit of a disaster because all of the food dye came out of the oil and sank down into the water. It ended black. WE did it a second time and decided not to put colour in with the oil which meant that the separation between the oil and water was more obvious.

WE wrote the experiment up in our Writer’s Notebooks. Looking forward to doing another experiment tomorrow!!


What’s your favourite experiment so far?

Science works!!!

On Wednesday we all went to Scienceworks because our Inquiry topic this term is how changes in temperature effect solids, liquids and gases.

We were able to look at the different exhibitions such as Sportworks and Think Ahead. We went to the Planetarium and learnt about the seasons and the night sky (identifying the stars in the Southern Hemisphere).

The highlight for me was the presentation at the Science Stage. Gordon did a few different experiments using liquid nitrogen. When he mixed water with dishwashing liquid the bubbles became frozen. He explained that liquid nitrogen is extremely cold and when it comes into contact with the dishwashing liquid most of the nitrogen disappears, it changes its state, contracts and spreads around.

He put liquid nitrogen into a bottle, then put a balloon on top. The cold air inside mixed with the warm air and caused the balloon to blow up.

When solids (such as a metal ring) were placed in liquid nitrogen it contracted slightly and could fit through the ring but once the ring went back to its normal state, it could not fit through.

A squash ball and blutac nail, placed into liquid nitrogen became so hard and brittle, that they could be smashed by a mallet!

We learnt that when gases cool down, they contract, when they warm up, they expand.

It was fascinating!!

Coke and Mentos Experiment

As part of our investigation into Solids, Liquids and Gas we carried out an experiment on Thursday.

We had already seen an experiment that was similar to this on You Tube but wanted to try it out for ourselves.

QUESTION: What will happen when Mentos are put into Pepsi and Mapsi Max.

HYPOTHESIS: The pepsi will froth up.

MATERIALS: Pepsi, Pepsi Max, Mentos, Tube


1. Take all of the materials to an area outside

2. Put funnel/tube into top of both bottles

3. Drop  3 Mentos into the funnel of the Pepsi and move away quickly

4. Drop 3 mentor into the funnel of the Pepsi Max and move away even more quickly!

FINDINGS: Both types of Pepsi fizzed up and went over the top. The Pepsi Max fizzed up way more than the Pepsi though.

CONCLUSION: The roughness of the Mentos combined with the extra chemicals in Pepsi Max make for a more impressive reaction.

Silly Science Slime!



IMG_1455 IMG_1453 IMG_1452Here is the slime recipe, it is a bit different to the one that we used in class. We found out that slime is a solid AND a liquid! It is a non-newtonian visco-elastic fluid! Now try saying that!?

We were told to be very careful with our slime and of the need to wash our hands after playing with it and to keep it away from small children.

Which science experiment did you like the most?

Silly Science

This Term the Grade 3 students at BHPS have been investigating Solids, Liquids and Gases.

Today we had a Science Incursion. It was really fun and we got to do lots of experiments.

I think that I am safe to say that our favorite experiment was making rockets…..

Making Rockets

You will need:

A film canister and lid

Bicarb. Soda



Place about 1/4 of a teaspoon of bicarb into the canister lid, flatten it.

Fill the canister to about 1/4 full with vinegar.

Put the lid on, quickly shake, place, lid side down on a surface and move away quickly.

Watch your rocket soar into the sky!

Helpful hint: Move away quickly as you may be injured if the canister hits you!


We made our own rockets using a small, cylinder shaped container with a rubber stopper.

Procedural Writing – How to make Slime

We are learning how to write procedural texts in writing this week.

Yesterday, with 3B, we made slime. First we made predictions (hypothesis) as to what would happen when we added water to cornflour. Some predicted that that it would become sticky or runny and they were right!

Here is our slime making procedural text.

Making Slime

You will need:



Food colouring





1.Put 1 cup of cornflour into the bowl

2. Add about a cup of water but you may need to add more.

3. Stir it around until really thick

4. Put 5 drops of food colouring in the bowl

5. Stir some more

Enjoy playing with your slime!

Thanks Miss Petz for organising this experiment for us!

What procedural texts do you enjoy following?


We had a fantastic time at Science Works on Friday.

The highlights were the Sportsworks Exhibition, Planetarium and the Cool Stuff Show.

It was so interesting to see Space from a rocket and some of the planets and star patterns in the night sky.

The Cool Stuff exhibition was really fun, we saw that when objects are frozen with liquid nitrogen, they get smaller.

Welcome back to school for Term 4!

What a welcome it has been with such hot weather. Yesterday when we checked the temperature it was 33 degrees. Today it is going to be hot again.

We are looking forward to a great term and our new inquiry topic is Solids, Liquids and Gases. Yesterday we talked about what we already know about this topic and we talked about what we would like to find out. We looked at some science experiments on You Tube and came up with some good ideas. These posters give definitions of solids, liquid and gases.
