KEEPING THE PAST ALIVE!

The yellow reading  group was reading about' Keeping The Past Alive.'
We learnt about how the people in the future kept the things in the past still in the same piece.

Another thing we learnt about is, in the museum they use special chemicals to protect the important and precious things.

We learnt about the Mona Lisa painting that Leonardo da Vinci created and how it is protected .

Something that is special to you and reminds you of something good that has happened, is a treasure. This means you want to keep it for as long as possible. You need to look after your precious things. You need to keep things clean and polished in a protective box or a container. eg medals, toys, books etc.

Nature is helpful in preserving hard objects like shells, bones and teeth . Sometimes these things are buried in mud or sand and can turn into fossils. We know a lot about dinosaurs, because scientist studied fossils of their bones.

 Some ways of perserving objects are :

BONE:

*dry it and clean it

*put it in a special container! Don't bend it or fold it!

INSECTS:

*dry it out

*put it somewhere that other insects can't eat it. E.g. picture frame under glass.

*pin it so that parts don't break off.

PAINTING:

*don't really handle it too much                                                        

*protect it in a frame

*don't always put it in a sunny place

I hope you enjoyed our work!

Great tables practice link

A good site for children to practice their tables from. 

Balloon Blowing

This experiment is about blowing up a balloon with CO2.  First I put the water into a drink bottle, then put a teaspoon of baking soda in and shook the bottle until they dissolved together.  It was then time to quickly add the vinegar or lemon juice and put the balloon on the mouth of the bottle.  We watched the balloon grow "make sure it doesn't pop!".  It was really fun doing that experiment with Room 7.

Science Fun

This is Room 7 doing their fun science experiments.  

This is an experiment performed by Room 7 students. The experiment was called 'The exploding lunch bag'.

We added vinegar to warm water in a bag, then we added baking soda and sealed the bag shut. We watched as the bag expanded until it exploded.
It was the gas (carbon dioxide)  created by the combined ingredients that caused the bag to explode.  

A great experiement but I think I will stick to putting just my lunch in the bags from now on!
