Year 6 tech

A couple of my friends and I have been making cars. We have started making boats. We just tested our boats today to see if the would float. We could only use tinfoil to make the boats and we weren't allowed to use any other materials otherwise it wouldn't be an experiment. When we made the boats we only took about 20 mins as when we made the cars it took about 1 hour.

This is our car I and Bella made this.

Making ready salted chips.

Ps: We don't have any photos of the chips.
WALT: To determine what method makes the crispy and tastiest chips.
Last week we made some chips depending on if we wanted to cook them in the microwave or the oven we picked the microwave. The oven ones turned out better than our ones because they were much crisper they were quick and easy prosses because they only had three ingredients.

Making hokey pokey!!!!

WALT: Explain the science behind making the hokey pokey

When we made this we had to use 3 ingredients which are Baking soda, Golden syrup, and sugar

When you add the baking soda you have to stir very very quickly otherwise the mixture will dry hard and stick to the side of the pot. The science behind making hockey pocky is that the sodium bicarbonate releases gas that makes the sugar mixture puff up which is why you need to have heat which causes it to fluff up.

I enjoyed eating it at the end about it was a little bit burnt because we kept it in the pot for a little bit to

 Long. I found it challenging to try and not burn the mixture because if you do it doesn't taste as nice as it does when it is not burnt. To be BTB we could have used a fish slice to flip it off.

WALT: Explain changes in the two batches of cookies.
Over the past two weeks, we have been doing food science such as making cookies.
I enjoyed eating the cookies at the end.
I found it challenging to work in a small space with so many people.
