Science experiment reflection

Posted on by nedcbgs

1.  What were the highlights?

Working as a group, learning about strength and how long some elastic bands  can go with different thickness but same length. learning about scientists, Asking scientific questions. Being curious about science.

 

Our Experiment Plan

From Hannah, Izzy, Ned and Stavros.

Is the strength of the rubber band dependent upon the thickness.

Testing different thickness of an elastic band with weights. How much weight can we put on an elastic band without it not breaking

Every 20 seconds we will put another 3 kg of weight until it breaks.

We are going to observe how long until the elastic band breaks.

We are going to keep the same the length of the rubber band.

That the elastic bands and that will be only one of them and the will only hold about 3kg of weight  Because the type of thickness will have to much weight on it. 

The Materials we are using are: 

Three elastic bands that are the same Length but different thickness.

5g of weight and also 1 kg of weight.

2 bike hooks 

Ruler 

Camera to video it

Something to hold it with

This is a drawing of our setup: 

Hang bike hook on whiteboards.

Put rubber band on bike hook

What another bike on the bottom of the rubber band

Put one waves of 5g on Second by cook and wait 20 seconds and then keep putting some more weight on it until it breaks 

Thanks for reading I hope you liked it. 

BYE!!! 

 

What were the challenges? Trying not to have any  variables, sometimes it was really hard to agree on some things for  our experiment.Trying to get the same length but different thickness. Our idea being changed it was originally same thickness different length.

How you solved the challenges? 

We discuss your different ideas and put them together. 

Changing a mistake on our experiment planning sheet.

Asking the teacher for help for when we had a confusion on the experiment plan.

Things that you learned from doing the experiment?

That experiments can have a different results than other hypothesis.

That hypothesis are not always right. Learning new words and thinking like scientists.

Self correcting ourselves when we made mistakes.

We realised that our hypothesis was wrong.

And we learned from our mistakes.

CBCA book awards

CBCA book awards  

This week was the CBCA book awards and our grade was doing the picture book category we had 6 different books to read and judge.

The books we were looking at were Mopoke, A Walk In The Bush, Swan Lake, Florette, The Great Rabbit Chase and Ten Pound Pom.

The Book that won the award was A Walk In The Bush, because each page had better illustrations than the one before and it had a very good story.

A walk in the bush was not my favourite book, my favourite book was mopoke because it was really funny and I like to see how many different pokes there are?

If your favourite book wasn’t mopoke what was your favourite book?

Children should be able to go to bed when ever they want.

Imagine what would happen if you let your child choose when they wanted to go to bed, IT WOULD BE CHAOS!
Definitely not, Think of all the things they could get away, with especially when you’re asleep. If children were allowed to go to bed whenever they wanted to they would get so tired they’d fall asleep during class and that’s something no parent wants. it could also effect their education greatly.
if the child gets to stay up that means the parent or parents have to stay up which will also affect them at work because they won’t be focusing as well and sleep is crucial for surgeons because if they make a mistake it could have horrible consequences for the paciant and the doctor.
And finally, even scientific studies have shown that watching T.V or playing video games will muddle up your sleeping pattern. That means you won’t get the 8 hours of sleep you need! And if you don’t get the sleep you need you and your child are going to be very cranky in the morning and who in the world wants to be cranky? I know I don’t.
And surly you will agree with these.

Science incursion reflection

Posted on by nedcbgs

On the 7th of August 4BM went to the senior school science lab. We were learning about metals. We received a sheet and we had to put a bunch of tests on them with things like magnets and transferring electricity. And we had to sort some cards into different categories I was the first one to finish. Another one of the activities we did was a electricity experiment. So we pretty much had to clip two wires to all of the materials and see if they will turn the light on and then record them on a sheet. Me and my partner Stavros also figured out that if you places the wires together on one of the activities you can make electricity.
