I hope you have completed your bootcamp question booklet and you now have to complete your Easter revision booklet.
I will post the answers over the holidays, so keep looking at the Standard Grade Zone.
Anyway have a happy Easter holiday but remember to work hard.

Here is a video taken with my first year class when we demonstrated that carbon dioxide gas is heavier than air.
We put two plastic bags at the end of a long piece of wood.
Then we balanced the beam of wood and poured out the invisible gas made by adding vinegar and baking soda.
Later we tested the gas with lime water. The gas turned the lime water milky. This test told us the gas was carbon dioxide.
Well done 1/7.
My S1 class enjoyed making three dimensional pyramids showing the numbers of organisms at each level of the food chain.
The base of the pyramid is larger because there are lots more plants than rabbits. Lucky rabbits.
Some questions.
You can download a pyramid of numbers cut out sheet and enjoy making a 3D pyramid of numbers for homework.
Download your own cut out pyramid of numbers here.

This is a great site to help you understand the electric circuits you have been studying.
You can run it on your computer or download it and use it offline.
I set my young scientists a Christmas Poster competition, all they had to do was dream up the best present that a scientist could find in his/her stocking on Christmas morning.
Have a Merry Christmas and a Happy New Year.
Last June I placed some photographic film into a tin cannister with a small hole punched into its side. The tin cannister was then attached to a clothes pole in my backgarden and left.
This afternoon I fetched the cannister and took the photographic film out. My son John scanned the photographic film and with the aid of some image software made the image negative.
The result is the picture above.
The picture clearly shows the path of the sun through the sky over the last six months.
I believe you can see we didn`t have a great summer by the broken lines at the top. More sun shone in the month of October.
This has been a fascinating simple project that was carried out very easily.
If you want to try out the project then follow the link below.
In a few weeks time it will be the winter solstice when the sun will be in its lowest arc across the sky. Try it out over the next six months and make a record of the sun`s path yourself.
