Guess the Weight Scavenger Hunt Starting with one object, children will decide which objects in the room are heavier or lighter than that object. Materials Needed: • Two baskets – One labeled Lighter and the other labeled, Heavier • Objects set aside that the children are to weigh (make sure they can fit on a balance scale) • One object to use as a measuring tool. Make sure it is something that the children can carry with them, fit on a balance scale, and easily manipulate as they weigh both objects in their hands. • A balance scale Introduce Activity: 1. Ask the children to explain weight, the concept of weighing something. Ask the children about their experience with being weighed or weighing something. (The doctor weighs you, you weigh produce at the grocery store etc.) 2. Demonstrate how the balance scale works. Weigh objects that are the same weight, and objects that are of different weight emphasizing which is heavier and which is lighter. 3. Tell the children that they are going on a Scavenger Hunt today to find objects that are heavier and lighter than an object you will give them to use as a comparison. Engage the Children: 1. Give each child his/her measurable object. Explain that they are to find objects that are lighter or heavier than their object. Ask the children how they will be able to tell? (Use the balance scale or tell by using their hands) 2. First, the children will find objects that are heavier than their object and place it in the basket labeled “Heavier”. 3. Then the children will find objects that are lighter than their object and place it in the basket labeled “Lighter". 4. After all the objects have been collected, gather the children around the two baskets to discuss the objects collected in relation to their own objects. If there are some discrepancies, put the objects on the balance scale to determine the weights of the objects. Additional Extensions • Once the children have collected items using their measurable objects, have the children switch objects and do the Scavenger Hunt all over again. • In addition to placing the found objects in the two baskets, the children can also record their finding on a recording sheet. Have a space at the top of the page where you can write or draw a picture of the measurable item being used and then have a column for the lighter objects and a column for the heavier objects. The children can either write the name of or draw a picture of their found objects.
