Kid Science - Activities for Home

Do you know how water LEAVES (hint) plants? 

Do you know why the Rio Grande/Rio Bravo does not run straight?

To find out, try these experiments.

Water and Plants NA01159A.gif (1012 bytes)

Plants need water to grow. They takes water up through its roots.  Do you know what happens afterwards. 
To find out, find a plant around your house that has big leaves, but not glossy or coated.
Take a ziploc baggie (ask permission first), and place it over a bundle of leaves. 
Then use the a rubber band or a twistie to hold the baggie at the base. 
Leave it alone for a day and make sure it has plenty of water. Check it the next day.
What happened? 
Is there anything in the bag?
Look closely.
Try it again, except with a plant without any leaves. Is there a difference? 



Wandering Riversmountns.wmf (3882 bytes)

Why do streams wander and not just travel straight?
To find out, take a portable flat surface and cover it with a thin layer of dirt.
Place one end a little higher than the other, so there is a slight incline. Place objects like rocks and little mountains of dirt around on your surface.
Now take a paper cup and make a hole on its side.
Place the cup at the top of the high end with the hole facing downward. 
Gently pour water into the cup.
What happens to the path of water?
Is it straight?
Now move a rock into the path of water.
When the stream moves around the rock, move another rock to block it.
What happens when you move a mound of soil in the path of water?




  1. Plants lose their water through leaves.  This process is called transpiration.

  2. Water takes the path of least resistance. It finds the easiest way around an object, not through it.
