Celery Color Absorption Experiment

The video is a tutorial on how plants absorb water, demonstrated through an experiment with celery sticks and colored water. The process involves setting up cups with water and food coloring, placing celery in them, and observing the color change over two days. The experiment illustrates capillary action, where water moves against gravity through the plant. The video concludes with a discussion on the results and the scientific principle of capillary action.

What is the main purpose of the experiment introduced in the video?

• To understand the growth rate of plants

• To measure the height of celery sticks

• To learn about different plant species

• To see how plants absorb water

What is the first step in the experiment after gathering materials?

• Placing the celery in the cups

• Pouring water into each cup

• Cutting the celery sticks

• Adding food coloring to the water

What does the term 'agitate' mean in the context of the experiment?

• To mix or stir

• To remove the celery

• To change the color

• To add more water

What hypothesis does Ryan make about the celery in colored water?

• The celery will grow taller

• The celery will remain unchanged

• The celery will change to the color of the water

• The celery will dissolve in the water

What did Ryan think would happen to the water level in the glass?

• It would increase

• It would decrease

• It would overflow

• It would stay the same

What observation is made about the celery after one day?

• The celery has wilted

• The celery has absorbed the color

• The celery has grown new leaves

• The celery has dried out

What color did the leaves turn when placed in yellow water?

• Blue

• Green

• Yellow

• Red

Why might some celery sticks change color faster than others?

• They are placed in more water

• They are cut into smaller pieces

• They are placed in multiple colors

• They are placed in cups with more celery sticks

What is the scientific term for the process of water moving up the plant?

• Evaporation

• Transpiration

• Photosynthesis

• Capillary action

What did the experiment demonstrate about plant behavior?

• Plants can grow without sunlight

• Plants can change color naturally

• Plants can absorb water and nutrients

• Plants can survive in any environment
