YOU WILL Demand:

Pennies
Eyedropper or pipette
H2o
Food coloring (makes seeing this in action MUCH easier, just is optional)
Small bowls

PENNY EXPERIMENT Ready

STEP one: Add water to both of your bowls, and to one of them add green food coloring. This is an optional footstep if yous want to meet the drops a bit better.

Pace 2: Use an eyedropper or pipette to pick upwards and advisedly drip one driblet of water at a time onto the penny.

Pace iii: Count how many drops you lot can fit onto i penny until the water overflows. We were able to get ours up to almost 27!

Go ahead and record the data for divide trials on the same coin. What can you conclude?

PENNY Drib VARIATIONS

If you lot want to add a little fleck of variety to this experiment, swap out the pennies for nickels, dimes, and quarters. Ask your students to approximate how many drops will fit on each coin. Tape the appointment from the experiment and make a course graph nautical chart with your results!

WHY Do SO MANY DROPS OF H2o FIT ON A PENNY?

Were you surprised to find that a lot more than drops of water fit on a penny than you lot predicted? We had 27 drops of water on ours!

Surface tension and cohesion is the reason y'all can become so many drops of water on a penny. Cohesion is the "stickiness" of like molecules to 1 some other. Water molecules love to stick together! Surface tension is the result of all the water molecules sticking together.

Learn more than nearly surface tension of water!

Once the h2o has reached the edge of the penny, a dome shape begins to form. This is due to the surface tension forming a shape that has the least corporeality of expanse possible (like bubbling)!
