Nature Study Invertebrates

Nature study can be as simple as a short walk in the neighborhood or as elaborate as a week in a National Park. Don’t make it hard.  This month, We are going to look for spiders. You’ll be able to find pictures of these items and many others online to explore with your children. Remember: you don’t have to know all the answers to your kids’ questions because you can look up the answers together. 

Here are some questions to consider with your kids while you explore:


  • How does the earthworm crawl? Turn over? How does it move differently than other legless creatures?
  • Is an earthworm always the same length?
  • How many segments are in the worm? Do all worms have the same number?
