This year, we are using AOP Lifepac for Science. We are almost done with the first quarter, and my little grader is enjoying the activities in this curriculum. It seems that he is interested in every experiment provided, and I have to admit, that I am also enjoying it as a parent-teacher.
We started a unit on plants and recently, we studied stems. For the little ones to better understand the job of the stem, we did a stem experiment showing how water & minerals travels to the leaves through the stem.
For this experiment, you will need;
a small jar with water
a celery stem
We started by cutting off a piece of celery stem. Then, I let the kids examine the end of it with a magnifying glass, for them to see the tiny tubes on the stem where the water travels towards the leaves.
Next, you will have to put food coloring into the small jar with water, and put the celery stem. Let it set for a few hours. After four hours, the celery looks like this!
The leaves turned reddish! How did that happen mom? The boys blurt out in amazement. It clearly showed how the water travel to the leaves through the stem.
