Mealworms

Grade level: second grade

This is an integrative science and math unit of study on the life cycles of insects. Primarily focusing on the life cycle of a grain beetle.

Topic & Background information:

Students will use the scientific process to become familiar with mealworms and their life cycles as well as observe and record data for a changing population of mealworms.

The mealworms are a wonderful example of the life-cycle metamorphosis. The students will witness first hand the changes (from the second stage) of a larva into the pupa and finally into an adult. The students will watch the hungry mealworms transform into pupas where they will emerge from the pupa case as the adult beetle. Mealworm beetles range in size from one to one and a half centimeters. The larva and the beetles live in an environment where there is grain and flour, such as in bakeries, mills, warehouses, and people’s homes. They can be bought from most animal dealers.

Commentary:

Students will use the scientific process to become familiar with mealworms and their life cycles as well as observe and record data for a changing population of mealworms. This unit is hands-on. The kids will be engage and actively participating in every activity. They will be constructing their own knowledge from this experience.

What are you going to do to get the kids engaged?

Explain that they are going to get their new pets. Their new pets are going to live in their "bug apartments" (the petri dishes). Each student will receive their own petri dish and their mealworm. Have students observe their new pet and name it. They will love being such an interactive part of the learning process.
