Wet Pennies

For Teachers 6th - 9th
Students conduct a simple test to determine how many drops of water, rubbing alcohol and vegetable oil can be placed on a penny before spilling over. They consider how varying surface tensions allow for different amounts of each liquid...

Science Experiments

For Teachers 2nd - 5th
Students do a series of three experiments. In the first experiment, the students work with a partner to protect an egg from a 12 foot drop. In the second experiment, the students investigate static electricity using balloons and yarn. ...

How Many Drops?

For Teachers 7th
Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

Take a Dip: Sticky Water

For Teachers 6th - 8th
Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.

Barge Building: What Floats Your Boat?

For Teachers 4th - 8th
Learners construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Earth & Space Science: Holding it Together

For Teachers K - 6th
Students estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.

Drops on a Penny

For Teachers 8th
Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

How Many Drops?

For Teachers 6th - 8th
Middle schoolers conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny...
