meal+worms

Mrs Lam, I gave my mealworms a slice of apple but they won't eat it, why? Another thing, can I give them whole meal bread or biscuit every day as food? I put them in a bowl of water and they just go to sleep. Why? How long is it until they grow to the adult stage? Oh by the way it's Wei Chuan.

Wei Chuan, you may want to record their changes and take note of the time for it to change from one stage to another in your Science journal :) Mrs Lam
