Here are three videos recorded by my science classes about cells. They recorded their videos using FLIP video cameras.
They put a lot of work into their productions. We hope you enjoy the videos and it helps you learn about cells.
Hi first year! Here is a video showing liquid turning into solid. This is a bit of a puzzle. Have a look below.
Quick question: What is meant by a change in state?
All these pictures of the onion skin`s cells were taken by 2-7 Science. They took the pictures using their mobile phone cameras and bluetoothing them to my mobile phone.
The mobile phone cameras were placed over the eyepiece of the microscope.
The pictures are superb.
Well done 2-7
James Dewar was a Scottish scientist born in 1842. He built a machine to change oxygen gas into liquid oxygen.
As result of this work he invented a special flask to keep liquids cool.
This was the Dewar flask.

Some questions:
Before the Easter break my S1 classes got together and made a series of videos about what they learned studying the Acid & Alkali topic.
Hope you enjoy the fun they had!
Happy Easter.
In our class we are beginning to study biotechnology. To start off our topic we all witnessed the amount of energy stored in a few spatulas of custard powder.
To release the stored energy I lit a candle and placed it into the can. I blew through a small pipe which led into the can. This caused the custard powder to rise into a fine powder. The lit candle then provided the initial energy to release the stored energy.
Check out the video and look at that flash of light.
Hi science lovers! Here is a wee song to help you think about food chains.
Hope you enjoy it!
Write down in your notebook the answers to these questions.
Hi First Year! Here are the pictures to download for your science notebook.
The bubbles of oxygen look marvellous. We know the bubbles are oxygen because when we collected them into a testube and put a glowing splint into the test tube the splint relit. This was told us that the gas bubbles were oxygen indeed.
My second year classes have been playing with the microelectronic boards all last week. The classes are very interested in microelectronics. We spent about half an hour looking at a deskfull of ipods, mp3 players and mobile phones talking about what happens inside these magical devices.
We also talked about creating microelectronic circuits that could benefit society. We will be hard at work in the coming weeks working in teams using the above boards.
So if any of you want to experiment click the picture of the board and have some fun designing your circuits.
