Celery Experiment is an experiment you can conduct with young children to show the importance of water. Water is important because it carries nutrients to all parts of the plants or to all parts of the body (for humans).
Here is the process of conducting Celery Experiment:
- celery stalk (cut at least one inch of the bottom part)
- food colour
- transparent glass
- Pour water in a transparent glass.
- Add food colour.
- Put celery stalk in.
- Wait for at least 20 minutes to see the changes happens to the celery.
The end product of this experiment is you will see that the color of celery changes. This happens because the water aids in transporting the food colour to all parts of the plants.
Our lesson for the first term is on Blood. As a culminating activity, we had Parent-Child Experiment to determine if Blood Type A can donate to Blood Type B or vice versa.
I did the experiment before our final experiment, and my children were telling me, “Wow, teacher, you are a teacher and a scientist. You are a scientist teacher!”
This simple experiment will make a child understand the concept.
- test tube
- dropper or pipette
- food color (red and blue)
- Label all cups (near the rim) with blood type names (A, B, AB, O).
- Pour water until half on all cups.
- Add a drop of red food color in Blood A cup.
- Add a drop of blue food color in Blood B cup.
- Add a drop of blue and red food color in Blood AB cup.
- Do not add any food coloring in Blood O.
- If the receiver is Blood A, then use a dropper to transfer the liquid in a test tube. Then, again use a dropper to add another Blood Type as the donor and see if there is a change in the color. If the color changes, it means that the blood types do not match.
- Blood O can donate to all blood types. In the experiment, it is colorless. Definitely, it won’t change the color of the receiver when it is mixed together.
- Blood AB can receive blood from all blood types.
- Blood A can receive from A and O.
- Blood B can receive from B and O.
After the Parent-Child experiment, the parents and children played Blood Game whereby we called someone who, for example, had Blood Type A, then those parents and children with matching blood types would huddle together.
It’s a fun way to make a child understand a challenging topic, and most of all, parents and children were able to spend time together doing a simple investigation!
Making a Heart Pump Model is a good way to make children visualize what happens when the heart pumps blood.
Here are easy steps on how to make a Heart Pump for your Science project:
1. Pour water in a jar until its almost full.
2. Cut the balloon’s neck.
3. Cover the top of a jar by stretching the balloon’s head.
4. Poke two small holes opposite with each other using a satay stick.
5. Insert a straw on each hole.
6. Tape the balloon’s neck on one of the straws.
You’re done! Now, press the centre of the balloon cover (heart) to see how water (blood) moves…
