Our new Plaster bricks

In inquiry today the people who's second brick didn't dry properly had to go up to the teacher to make a new brick. Our groups brick was good so we had to write a prediction on how long it will last and when it will break and why. We had to figure out where we will start dropping it from to.Our investigation is to see what we could add to make the plaster bricks stronger we will be testing them on Wednesday.
