Simple Science Experiment for Kids- Coloring Celery

Coloring Celery

Science is such a fun and exciting adventure that helps us answer questions about the world around us. Have you ever wondered how nutrients enter our food? Have you ever wondered how the soil and water actually help plants grow? Well if you have this science experiment will help you understand just that. Let’s get started Coloring Celery.

Little Passports

Check it out in action!

Comments on our video:

Yes! Water was spilled. Yes! Right after we did the first part of the video we wrote down our hypothesis of what we thought was going to happen. We also had to change our celery stalk because it didn’t have enough leaves (it took us a day to get a new piece of celery and cut it correctly and put it in the water, which is why it was a few days after the first video was filmed) and it wasn’t cut well where it fit into the containers comfortably (it kept tipping forward). The second half of the video was taken a day after we used the new celery stalk. So these are our results. We did end up keeping the stalk for a few more days and the color got even deeper, you can see the picture below.

Celery

Here are the details, so you can try this yourself!

What do plants need in order to grow and be healthy?

Sunlight? Air? Water?  Ice Cream? The right temperature? Soil? Room to grow?

Okay, ice cream is just on the list to see if you were paying attention but the rest are all correct answers. Have you ever wondered how plants pull water out of the soil with their roots and send it up to the rest of the plant? Try this and you’ll see how it works!

What you need:

  • Notebook/ Journal,
  • Pen or Pencil,
  • Crayons,
  • Tall clear containers (glass or vase works well),
  • Water,
  • Red and/ or Blue food coloring (Use liquid food coloring, not the gel kind.),
  • A long piece of celery with the leaves still attached

Result Timing: Overnight but a few days are even better!

What to do:

  1. In your journal (I will post an entry on how we made/decorated ours) you will write down what your experiment is on the top eg. Coloring Celery. You may want to write down your observations (things you see) of what the celery looks like before you do anything. Isabella drew a picture and colored it.
  2. Then you should make a hypothesis or prediction of what is going to happen when the experiment is complete.
  3. After the experiment or while you are conducting it you may want to write down any observations. You may also draw an after picture and color it in.

So now to the actual experiment!

  1. Fill your 2 clear containers with water. You can do this experiment with one container and one food coloring but we wanted to see if we split the celery how would it absorb the water, would it come out with two different colors?
  2. Once your 2 clear containers are filled with water you then add the food coloring to each container. One with a few drops of red (stir) and one with a few drops of blue (stir).
  3. (Have Parent) Cut the bottom off the celery and slice it in half but keeping it attached.
  4. Then place each half into a container filled with your colored water.
  5. Wait overnight, or a couple days (the color gets darker the longer it is in the water).
  6. Record your results. Was your hypothesis right? What is different about the celery after being in the water? Color a picture of how the celery looks now.

How it works

When a plant’s roots grab onto water from the soil, or, like our celery, from the water they’re standing in, the narrow tubes in the plant’s stem (kind of like drinking straws) carry the water upward to the other parts of the plant. This is called capillary action (a capillary is a very narrow tube). Since water molecules stick together, each tiny bit of water that enters the tubes at the bottom of the plant pulls up more water molecules with it.

You can try this experiment this colored water experiment again with a white carnation or daisy. Write down your prediction first and then compare it to what actually happens.

    This is a classic alongside vinegar and baking soda. Never gets old!
