On the first day that my two grandchildren (5 and 10 yrs old) arrived, we went for a nature walk. Equipped with a capture jar, we found a caterpillar egg case (forest tent caterpillars), many Woolly Bear caterpillars and several cocoons from unknown insect species. These were initially placed in the capture jar and back home they were put in individual jars that would act as terrariums. We also cut willow branches and these were placed in jars of water. They quickly root and sprout leaves within 5 days. Be sure to take many photos!
Maybe our next project will see us starting an Earth Day Cleanup of the ditch that leads to the creek behind my house.
