Penny droplet lab experiment
Instructions
1. Gather the necessary materials: a penny, an eyedropper, water, a piece of paper towel, a container or tray to catch any spilled water.
2. Place the penny on a flat surface, like a table or countertop.
3. Fill the eyedropper with water by squeezing the bulb, submerging the tip in a cup of water, and releasing the bulb to draw in the water. Make sure the eyedropper is completely filled with water.
4. Hold the eyedropper with the tip near the surface of the penny. Slowly squeeze the bulb of the eyedropper to release a drop of water onto the penny. Observe what happens to the water droplet on the penny.
5. Carefully add one more drop of water to the penny. Observe the behavior of the second droplet and compare it to the first droplet.
6. Continue adding droplets of water, one by one, to the penny. Observe what happens to the droplets as you add more.
7. Record your observations in a table or notebook. Include the number of droplets added and the behavior of each droplet (e.g., spread out, stayed in a droplet shape, merged with previous droplets).
8. After you have added several droplets, gently place a piece of paper towel on the penny to absorb the water. Note any changes in the penny's surface or any residual water left behind.
9. Clean up any spilled water and put away the materials.
10. Analyze your results and draw conclusions about the behavior of water droplets on the penny. Consider factors such as the surface tension of water, the shape of the penny, and the interactions between the water droplets.
