Life Cycle Lesson with managing behaviour.

Hello there, I am planning to teach life cycles soon for my 4th grade class. But i have so many behavoural issues. How can sucessfully engage in a life cycle lesson if i have to constantly rederect behaviours? Is there an activity that can go along with a class that works well for class like mine?

Hi Nidia,

Mealworms are easy to get and they are great for teaching life cycles.  Before long you have adult Darkling beetles, and you can show the larva (mealworm), pupa, and adult stages.  The children will love being able to observe these insects at different stages of development.  Using simple hand lenses and a document camera, students can observe the 6 legs on both the larval and adult stages.  There are simple investigations you can do with the adult Darkling beetles.  For example, you might have students check how they respond to bright light by burrowing into oatmeal, how they are able to hang on to the ledge of a wooden block,or how they back away from the scent of peppermint held near their heads with a cotton swab.

This article by Peggy Ashbrook has some great ideas: The Early Years: Counting a Culture of Mealworms (Oct. 2007) at: https://common.nsta.org/resource/default.aspx?id=10.2505%2f4%2fsc07_045_02_18

If you are near a fresh water pond or lake, you could bring a bucket of water in and have students hunt for various insect larvae that live in the water.  My students usually find dragonflies, damselflies, stone flies, caddis flies, and mayflies in various larval and nymph stages.  Occassionally they find something as large as a crayfish and as tiny as a hydra. I give them spoons and ice cube trays and have them hunt through a pile of algae mixed in water.  

Hope this helps.

Best,

Carolyn
