Chart 7
THE PISTON PUMP
- Water will naturally go from an area of greater water content, to an area of less water content.
- It will naturally equalize its own pressure.
Experiment 6
ASCENT OF LIQUIDS IN THE PLANT
MATERIALS: Flower with stem cut during the experiment, glass jar
with a wide mouth, red dye or food coloring.
- Fill the jar 3/4ths full of water and color it with a little dye.
- Then freshly cut the flower and stem from the plant, immediately placing it in the colored water.
- Then immediately cut the stem again while under the water.
- Observe what happens and write your observations.
Experiment 7a
ASCENT OF LIQUIDS IN THE PLANT
MATERIALS: A well developed corn plant or another plant still growing in the ground, a sharp knife.
- Cut the stem of the plant.
- Observe what happens and write your observations.
Experiment 7b
CAPILLARITY
MATERIALS: 3 glass tubes of different thicknesses, one of which is a capillary tube, a pitcher of water, red dye or food coloring, an eye dropper, a small glass container.
- Fill the glass container with water, 3/4ths. full.
- With an eye dropper, put a drop of red dye in the water and then immerse the three tubes.
- Observe what happens and write your observations.
Experiment 8
FORMATION OF WATER VAPOR
MATERIALS: A flower pot containing a plant with many green leaves, a large transparent plastic bag, a piece of ribbon, a watering can and water.
- First water the plant in the flower pot.
- Then cover the green parts of the plant with a bag and tie the bag around the bottom of the stem.
- Tie it tightly so that on air can enter.
- Then place the plant in the light but not the sun.
- Observe the plant after 24 hours and thereafter.
- Keep the soil well watered.
- Observe what happens and write your observations.
Chart 8
THE SUN'S DRINK
- The liquids in a plant automatically proceed to the top of the plant.
- The full plant seeks out the light since the light is what enables the plant to produce nourishment.
Experiment 9
WATER IS NECESSARY TO THE PLANT
MATERIALS: 3 test tubes, water, oil, three small plants, test tube rack.
- Put the water and one plant in one test tube.
- In another test tube put the oil and a plant.
- In the third test tube put only a plant.
- Observe what happens and write your observations.
