Water Drop Experiment
4th Grade
Objectives Exploring the concept of surface tension Making and testing a hypothesis by estimating the number of water drops that can fit on a penny and testing their predictions Analyzing data by averaging and comparing figures Materials Needed Water Drop Record Sheet Pennies (one for each student) Eyedroppers Cups of water Introduction Ask students if they have ever seen a mosquito or other small bug sitting on the surface of a body of water. Explain that the surface of the water acts as “skin.” It tends to hold together because the water molecules are attracted to each other. This is called surface tension. Tell students that they are going to conduct an experiment that demonstrates how water molecules stick together to create surface tension.

Float Your Boat
Kindergarten - 1st Grade
Objectives Students will predict how many pennies an aluminum foil boat will hold before it sinks. Students will test their predictions and record the results. Materials Needed Float Your Boat Record Sheet Aluminum foil Small plastic tubs Pennies Introduction Prompt students to raise their hands if they have ever traveled aboard a boat. Invite students to share what kind of boat it was (such as a rowboat, sailboat, canoe or cruise ship) and about how many passengers were on board. Ask students, “Can you ever have too many people aboard a boat? How do you know? What might happen?” Invite students to hypothesize and share their reasoning. Guide them to the conclusion that too much weight may cause a boat to sink.
