Dry ice

In week 11 term 1 room 7s bible in school teacher Mrs Graham came in and taught us about dry ice.

She explained how people use dry ice to make music by putting metal on it. She also told

us how dry ice goes strait to a gas rather than to a liquid first. then we got to have a game of ice hockey because the gas has a thin layer of gas under it

Fishy business

On Monday we got to experiment on a fish. First we had to estimate how much it would weigh. Most of us estimated that it would wiegh about 5 kgs but it weighed a good 12 kgs. Then we had to guess how long it was. We all thought that it was 1 meter long but it was 84 cm long. Then we took a fillet out and

had a look at that. Once we had done that we did an experiment on what sort of substance would remove the smell of fish best.

The substances were lemon juice, baking soda, water, vinegar, toothpaste, salt, soap and detergent. All the people in the class thought that vinegar would be the best but detergent won.

 

Silage stacking

In week 8 room 7 went to the Kelly farm to stack tyres on to the big silage stacks.

The stacks were covered by polythene plastic to keep the water off.

We ended up doing it in 2.5 hours rather than 4 hours. we ended up raising alot of money to go towards trips.  :)

 

Pencil portraits

In term one we did a self portrait of ourselfs. We had to use different shades of grey and black to show lines and other things like that. After we did that we had some practice on our eyes.
