CU 6.12Observing a Live Insect
The child watches borrowed ladybugs or mealworms in a ventilated jar for a few days, names the head, thorax, abdomen, and six legs, and then helps return or release them.

Before the lesson, set up the jar with food. Tell the child: 'These insects are our guests for a few days. We will watch them and then return them.'
- 2
Invite the child to sit and watch quietly. Ask: 'What do you see? How does it move?'
- 3
Look through the magnifying glass. Point to the front part: 'This is the head. It has the eyes and two antennae.'
- 4
Point to the middle part: 'This is the thorax. The legs grow from here, and the wings too if it has them.' Count the six legs together.
- 5
Point to the back part: 'This is the abdomen.'
- 6
Give a three-period lesson on head, thorax, and abdomen using the parts card.
- 7
Show how to check the food and moisten the towel or carrot, keeping the lid on.
- 8
After a few days, return the insects to the lender, or release ladybugs on a plant outside in warm weather.
What catches the child’s eye
- Six tiny legs moving one after another as the insect climbs the glass
- A ladybug lifting its spotted wing covers to open the thin wings underneath
Extensions, easiest to hardest
- Draw the insect and label the head, thorax, and abdomen
- Compare with other small animals: a spider has eight legs and two body parts, and a worm has no legs, so neither is an insect
- Watch mealworms change into pupae and then darkling beetles over several weeks
- Find insects on plants outdoors and count their legs without touching
Control of error
The insect itself: the child counts six legs and three body parts directly and checks the names with the control card.
Ready to move on when the child…
- Names head, thorax, and abdomen on the real insect
- Counts six legs and finds the antennae
- Watches without shaking or opening the jar
Guide note
Keep the lid on; children watch, and an adult does any handling. Mealworms are young beetles (larvae) whose six legs are near the head; the three body parts are easier to see on adult beetles or ladybugs. Release only ladybugs, and only in warm weather. Mealworms are not released outdoors; return them to their owner. Wash hands after cleaning the jar.
