Students will practice using a balance scale with this fun measurement activity! Use this worksheet to accompany a measurement activity to compare the weight of mystery objects concealed in paper bags. Each bag holds an item of a different weight (two bags should weigh the same) and is assigned a color to help students differentiate. Students can hold each bag and estimate the weight before they use the balance scale. This activity will help them practice determining which items are heavy and which items are light, which weigh more and less. Includes color-coded tags for each paper bag.
