In preparation for this science experiment, students practiced the procedure once prior to performing the experiment to make sure that it "worked."
Three types of paper towel:
- continuous roll
- Three bowls
- Three cups
- Adapted beakers -100 mL
- Non-adapted beakers
- Gather information.
- Cut continuous roll and perforated paper towels to 24 cm by 24 cm.
- Twist each paper towel fairly tight to form a wick.
- Bend each wick in the middle.
- Fill three glasses full of water.
- Place one of each wick in a separate glass.
- Put the other (dry) end of the wick into the bowl.
- Make sure the other side of the paper towel reaches the bowl.
- Check in one day.
- Measure the water using a beaker.
- Record your measurements.
Other types of paper towel could be used for this experiment.
Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.
