# Explore STEM Concepts With Stuffed Animals (Fun!)

This fun lesson combines STEM with show-and-tell.

Kids love the chance to bring in their favorite toys into class. So this year, why not invite students to participate in a stuffed animal STEMÂ lesson that teaches measurement, weight, inference, fractions, and more!

## Here’s How it Works

• Begin by inviting students to bring in a pet stuffed animal from their home. Ask students if they think they can determine an objectâ€™s weight and size without using standard tools. Write the childrenâ€™s answers down on the SmartBoard. (Later, test their answers by measuring and weighing to see if they are right.) Next,Â readÂ the bookÂ Measuring PennyÂ by Loreen Leedy to show students ways to measure a pet without standard tools.
• Have studentsÂ predictÂ which stuffed pet is theÂ longest, tallest, shortest, widest, and thinnest. Choose a nonstandard tool forÂ measuring. Have students record their pet’s measurements (ear, eye, nose, mouth, head, paw, arm, leg, tail, body). Also, have them write down the name of theÂ longest, tallest, shortest, widest, and thinnest pet in the class.
• Next, they willÂ estimateÂ which pet is the heaviest and which is the lightest. ForÂ science, construct aÂ balancing scale. Provide the materials and have students infer how they can use the material to create a weighing device. Then,Â weighÂ your pets! Have them write down the pets’ names in order from lightest to heaviest. Afterward, have them weigh their pet and compare it with pennies. What does their pet weigh in pennies?
• Then, students will describe their petâ€™sÂ attributesÂ using a bubble map. What makes their pet unique? Then, they will compare their pet to a friend’s pet using a Venn diagram. Once they compare with one friend, they will create aÂ fractionÂ by finding other peers whose pets have similar and different attributes.
• For writing, have students write down how they think their petâ€™s attributes might help their pet (animalÂ adaptations). Why does their pet have large ears? How does long shaggy hair help their pet? Where would their pet live? After they’ve made anÂ inference, they will work in teams to research all of their petâ€™s attributes on the computer or iPad to find out how certain attributes (like large ears) help animals.
