Activity - Talking Tubes . The students make a hole in the bottom of each container with a pencil. The students thread the ends of the string through the holes in the containers from the outside in, making a knot at each end of the string to keep the string ends from slipping out of the holes. One partner stands at one end of the classroom while the other partner moves as far away as needed to make the string taut. Keep the string taut.
Students shake the containers and describe the sounds they hear.
They predict what's inside. They record their predictions and then open the containers and compare predictions with actual results. Students shake several sealed containers and predict what's inside. They then try to find and match one container with another that has the same objects inside. Students take turns wearing blindfolds and listening to a partner drop beans on the table.
