Science

Group PP for technology at the moment is science, our teacher is Miss Hawtin. In science for this lesson we were looking at static energy. We blew up balloons and rubbed them on our heads and put them onto the ceiling. Afterwards we put a skewer though  the balloons to see if it would pop,the best place to poke the skewer is at the top of the balloon.

For science we had a red and a blue litmus and a universal Indicator which was yellow. The red was an acid so if the substance was an acid it would change to red. The blue was a base so if the substance was a base it would change to blue.
