  1. All About Magnetism -comments from Jack on his presentation.
    “I explained to the class that every magnet has two poles: A North Pole and a South Pole. I then showed them that “opposite poles attract each other” and “like poles repel each other“. I also explained that some rocks contain magnetic metals.

2. Acids & Bases: Comments from Alex on his presentation.
I demonstrated the reaction that occurs between an acid and a base. I showed that when they react Carbon Dioxide CO2 is created. I demonstrated this by making a volcano. I used vinegar (acid) and bread soda (base) to create the eruption! To maker the eruption more realistic I used red food colouring to make it look like lava.

3. Finger Print Demonstration – comments by Charlie
“I had an ink pad next to me and I told the second class pupils to put either their thumb, or their index finger into it. After they had dipped their finger into the ink pad I told them to press their finger firmly onto the page and not to move it. Once they removed their finger I used a magnifying glass to identify which type of finger print they had. The most common types are: The Arch, The Tentarch, The Loop and The Whorl.”

4. Cells: Comments by Kian.
I showed the classes a fly’s wing under a microscope. It has hundreds of cells. Every cell has a control tower called the Nucleus. Every cell also has a jelly like substance called cytoplasm. Everybody has billions and billions of cells.
