Pupils in grades four to six spent a term learning about their chosen project before putting it into practice.

Pupil Cayla Attard, 10, said it was the second time she had made a baking soda volcano.

“I wanted to make it again. It’s really fun and I also love science,” Cayla said.

Pupils were encouraged to vote for their favourite project at the fair and certificates were handed out to those with the most votes.

Teacher Gabby Jones said pupils worked on their project at school and home, which got families involved.

She said pupils took their own direction.
