Objective:
To observe and understand how capillary action works and how it relates to the way plants absorb and transport water.
Materials:
- White paper towels
- Crayola washable markers (various colors)
- Clear plastic cups
- Water
- A ruler (optional)
- A notebook and pen for observations
Procedure:
-
Setup:
- Fill each plastic cup with water, about halfway.
- Take a white paper towel and cut it into strips about 2 inches wide and 6 inches long.
-
Color Application:
- Ask each student to choose a Crayola washable marker and color a small circle (about the size of a quarter) about 1 inch from the bottom of the paper towel strip.
-
Observation Experiment:
- Instruct the students to carefully place the end of the paper towel strip (below the colored circle) into the cup of water, making sure not to submerge the colored circle itself.
- Position the paper towel strip so it hangs over the side of the cup slightly, allowing the water to travel up the strip via capillary action.
-
Documenting Results:
- Have students observe what happens to the colored circle as the water travels up the paper towel. They should note any changes in color or how the color spreads upward along with the water.
- Encourage students to measure how far the water travels every 5 minutes using the ruler, recording these measurements in their notebooks.
-
Discussion and Learning:
- Discuss as a class what they observed. How did the water move against gravity? What happened to the ink and why?
- Explain that this is similar to how plants draw water and nutrients up through their roots and stems using capillary action.
Extension Activities:
-
Experiment with Different Colors: Have students use different colors to see if some colors travel faster or are affected differently by the water.
-
Use Different Materials: Test how water travels through different materials like napkins, toilet paper, or different types of paper towels.
-
Art Integration: After the experiment, students can use the now colorfully dyed paper towels to create an art project, reinforcing the science lesson with a creative activity.
Conclusion:
This project not only demonstrates an essential scientific concept in a visual and engaging way but also encourages curiosity, observation skills, and understanding of plant biology. By using Crayola washable markers, students see vivid, real-time results of capillary action, making the abstract concept tangible and easier to comprehend.
