What's inside the boxes challenge which the children loved! 3 different sizes and weights which all made different noises (according to what was inside) encouraging the children to use all of their senses, and then write their guess on the box. Also great for prompting discussions with each other.
This is a fun activity to explore the science of balance and weight in the classroom. Have the students use the classroom balance scales to see how much items from their pencil boxes weigh. Does it weigh 1 bear, 2 bears, 3 bears, or more? Your students will have fun weighing their school supplies and recording their data!
