Well, a little smouldering, really. Students used magnifying glasses to focus the energy of the sun to a point on different colours of paper. The experiment was designed to test the effect of colour on heat and light. Students Used a standardised counting method ("1001", "1002", "1003", ...) to determine how long each colour took to smoke and smoulder.
We discovered that black caught alight within around 5 seconds, whereas yellow took more like 22 seconds. No group successfully ignited the white paper.
We then had a discussion about what this all meant, which clothes to wear on sunny days, and decided we needed to learn more about colour and light.
On Tuesday in the middle block room seventeen did a science experiment outside the class. We did it with the magnifying glasses. First we point the magnify glass to the sun and put it on the paper. We all tried to put it on the white paper but we all failed because I think the sun only likes the colours, not white.

Our sun experiment on Tuesday.
On Tuesday, we did an experiment with coloured paper, magnifying glasses and tables for recording. We found out that the white paper did not burn. We had to line the magnifying glasses up with the sun.
Black burned the fastest and blue was the second fastest.

On Tuesday we did a science experiment .We used colour paper and magnifying glasses.We made the paper burn from putting the magnifying glass against the sunlight. Then hold the magnifying glass up to the paper and then it will burn.

What a great experiment R 17. Interesting how the different coloured paper changes the time it takes to burn!!
