Just like a doctor needs all of their materials before an examination, you'll need to gather all of the materials to create your stethoscopes! Specifically, you'll need empty paper towel rolls (or extra-long craft rolls), lightweight funnels, tape and any desired decorating materials.
This activity can be completed with or without decorating your stethoscope—but it is much more fun with a little decoration! Try simple decoration with crayons, stickers or colorful tape.
If you chose to decorate and use any wet materials like paint or glue, allow the tubes to dry completely before continuing, as children will be putting their ears and bodies against the tubes.
Place the paper towel roll over the narrow spout of the funnel. Using tape, adhere the roll to the funnel. It may be easiest to add tape to the widest part of the funnel.
Have the children take turns listening to each other's heartbeats by holding the funnel to a child's chest and listening through opposite end of the roll.
