This afternoon we took our volcanoes outside and simulated an eruption.
First of all we tried 2 tbs or bicarbonate of soda, 1 tbs of washing up liquid and 30ml of vinegar. This wasn’t very successful and Miss Booth’s Volcano didn’t erupt. We then thought about how we could cause a bigger reaction and came up with out own quantities.
Here are some of the results.
We then had a go using coke and mentos. The reaction wasn’t quite as fierce as we had expected. I wonder what we could have differently?
This Year, we have been learning about our digital footprint. We though about which internet sites we had used over the past few days.
We then thought about how to keep ourselves safe when using thee internet. We created our top ten top tips!
Flowers are not just pretty petals and pollen. This afternoon we dissected our flower and found out that they are actually made up of lots of different parts.
Once we had dissected the flower, we labelled the different parts.
Next we are going to find out what each part does.
We’ve had lots of fun experimenting, as well as developing our investigation skill in class 3 this week.
On Monday we looked at how destructive air can be. We filled the bottle full of hot water then poured cold water and ice over it. After a minute or so the bottle began to crush!!
Did you know that gloop can dance? We made out gloop boogie on Tuesday afternoon.
The he vibrations from the loud music we played agitated the mixture of cornflour and water and made it look like it was dancing .
We followed Miss Booth’s instructions to make gummy worms wriggle on Thursday. We soaked them in a solution of bicarbonateof soda and water for half an hour. Next we dropped a worm into a cup of white vinegar and watched them wriggle to the top.
We finished our week with a bang (literally) this week. The chemical reaction between the bicarbonate of soda and vinegar filled the bag with carbon dioxide until it went BOOM!
Today it was Year 3’s turn to come for the science experiment enterprise with year 4. A few children turned up and had a lovely time exploring what happens when you mix together bicarbonate of soda, washing up liquid and lemon juice.
The bicarbonate of soda, when mixed with lemon juice, is forming carbon dioxide gas. As this fizzes up in the washing up liquid, it creates lots of soapy bubbles – wow! Is science magic?
Last week we learnt all about the Native Americans. We made our own headdresses but we are yet to decide who will be chief!
This afternoon Miss Booth gave us a map of the U.k. The problem was, it was broken into pieces! It was tricky but we got there in the end.
Can you spot where we went wrong?
