Drops of Water on a Penny Lab Worksheet
The drops of water on a penny lab worksheet is a simple and engaging experiment that demonstrates the concept of surface tension. The purpose of this lab is to investigate how the number of drops of water that can fit on a penny varies with the type of liquid used.
Materials
- Penny
- Water
- Eyedropper
- Paper towels
To gather and prepare the materials, follow these steps:
- Find a clean penny and place it on a flat surface.
- Fill an eyedropper with water.
- Place a paper towel next to the penny to absorb any excess water.
Procedure
- Hold the eyedropper vertically above the penny and slowly release a drop of water onto the penny’s surface.
- Count the number of drops of water that fit on the penny’s surface before the water starts to spill over the edges.
- Repeat steps 1 and 2 for different types of liquids, such as rubbing alcohol or vegetable oil.
- Record your results in a table.
Data Collection, Drops of water on a penny lab worksheet
To collect and record data during the lab, create a table with the following columns:
- Liquid
- Number of Drops
Record the number of drops of water that fit on the penny’s surface for each type of liquid tested.
Data Analysis
To analyze the data collected during the lab, compare the number of drops of water that fit on the penny’s surface for different types of liquids.
Determine which liquid has the highest surface tension and which liquid has the lowest surface tension.
