Joshua is a year 5 Scientist who researched chemical
reactions. He wanted to know what mix of
vinegar and baking soda make the most carbon dioxide. To do this he needed a balloon, vinegar and baking
soda. Joshua did a wonderful job showing
his results, first in a table and he then transferred this information into a
graph. He had to measure the
circumference of the balloon. What a
great effort Joshua, I wonder what topic you will pick next year!
