Grade 3 students decided to make a rock. They brought wax paper, plastic cup, plastic spoon, sand, gravel, white glue and water to school. First, they placed a wax paper over their work area. Then, they placed 1 spoon of sand, 1 spoon of gravel, and 1 spoon of glue to the cup and added few drops of water and stirred the mixture until it formed a lump. After that, they poured the mixture onto the paper and let it dry. Finally, a model of rock was made. Give it a try!
