Watch It Grow

We have been using our mealworms in a couple of investigations this week. We used our Investigation Planner to help us think about how to ensure a fair test occurs and to give us a template to record our observations.

We were able to draw two conclusions from our investigations: mealworms will grow and develop better/faster in warm temperatures and mealworms like the dark.

Here are some pictures of our light/dark investigation. The children enjoyed timing how fast it took for all the mealworms to go into the dark.

       

    As you can see, two mealworms didn’t make it into the dark. This gave us the perfect opportunity to wonder why we thought this had happened. The children came up with lots of good suggestions: they were saving energy, getting ready to change into a pupa, they were having a rest, they were sick, they were confused.

We were also able to talk about the importance of completing multiple tests whenever carrying out a science investigation. The children realised the problem we would have had if we had only used 1 mealworm and it had been one of these two that stayed in the light!

Well done on another super science learning session, Room 38!

    Thank you for these updates Cordelia, I love hearing Connor tell me about the stages of a meal worms life, and seeing this helps me to understand some of what he’s talking about. Can’t wait to show him the pictures.

      We have really enjoyed having the mealworms in class. I think we will miss them when they go next week 🙁

          Haha, Yes! We have also talked about the existence of the food chain, so hopefully the children will be ok when the mealworms go to Mrs Collinson and her chickens!
