BLOG HOMEWORK FOR FRIDAY: Write a sentence for each of the Enlightenment figures you learned about last week on the BLOG COMMENT BELOW: Alison Rutherford, Robert Adam and James Watt- saying ONE thing that you have learned about their work during the Enlightenment.

Today we learnt about the success of Joseph Black- a chemist who discovered carbon dioxide. Once we had agreed on what carbon dioxide is, a gas; the impact it’s having on the world, global warming; and some of its sources, car fumes; we were able to try and grasp what it might ‘look like’.

But how could we create carbon dioxide, and capture it? Well… Steve Spangler had an idea: (watch the video below)

Mr Cook was reluctant to do the science experiment as it looked a little ‘foamy’. Mrs Prentice had offered, but SUDDENLY ‘hurt her arm’. Mrs MacLeod had ‘cut her finger’; therefore Mr Cook left with no choice. With his marigold gloves, safety glasses and apron, he was able to do the experiment.

At first he showed the reaction between bicarbonate of soda and vinegar. He then showed what it would be like for 50ml of vinegar, keeping all of the other variables the same, before showing 100 ml.

We then got into groups and tried the experiment ourselves. Each group had to measure out a different amount of vinegar, but keep each other item the same. We found that when we reached 125ml, it POPPED!

WE have recorded our answers in the table below, and made our conclusions.

Mr Marigold ended with one final experiment, showing what 200ml looks like- WATCH OUR VIDEO BELOW!
