The preschool students experimented with worms in science class. They started out by discovering how their own eyes can still see the light of a flashlight even when their eyes are gently closed. Each preschool student was instructed to gently close their eye and the teacher shined the flashlight towards their eyes. They were still able to see the light even with their eyes closed.?
Then the students placed a worm on white paper and shined the flashlight just in front of it. They were able to see that the worm moved away from the light. There was a dark spot in the center of the ray of light and the worm tried to move towards that dark spot.
The students tested to determine what kind of temperatures the worms liked. They filled a plastic bag about 1/4 full of ice water and securely sealed it. They placed the bag at the edge of the worm and discovered that the worm kept trying to crawl underneath the bag but would not crawl on it. The worms did not like the cold temperatures.
Next the students discovered on what kind of surface the worms preferred to crawl. They placed a sheet of sandpaper next to the white paper. Once the worms entered the surface of the sandpaper, they were crawling faster than on the white paper. The worms preferred the grip of the sandpaper. The students thought it was fun to set out two worms side by side and see if they would race across the paper.?
And, finally, the students placed a handful of pebbles on a plate and placed the worms on top of the pebbles. They quickly saw the worms burrow their way down into the pebbles until they were completely hidden underneath the rocks.
This was a very fun experiment for preschool students to see what kind of habitat worms prefer. The preschool scientists discovered that worms like moist, dark, and warmer habitats.
