Ask the children to draw pictures of various insects. After they are done, introduce more formal diagrams of insects, and then have the children try to draw them more accurately. Label the parts of the insect's body. Younger children can color in pictures of different insects and try to write the name of the insect. Ask the children to draw the habitat where they think the bugs might live and what they might eat.
Take the children outside and look for insects. Have them watch ants crawling around and talk about where they live and what they eat. Do the same with other insects you spot, such as caterpillars, butterflies and moths. Use magnifying glasses to get close-up looks at the bugs you see. Teach about seasonal bugs, so the kids can learn which bugs are out at which time of year and why.
Have the children write and illustrate a short story from an insect's perspective. It could be an ant running away from giant feet, or a bee endlessly flying from flower to flower collecting nectar. Help younger children with the writing, but older children can do this independently. Alternatively, have the children keep a journal about the bugs they've seen. They can combine drawing and writing skills by drawing and labeling the bugs and their habitats, what they eat and what they do.
Do crafts about insects, such as creating a dragonfly or butterfly from empty paper-towel rolls and tissue paper. To teach more about insect habitat, create a home that certain insects would love. Use a cardboard or plastic box and fill it with items that insects could hide in, such as pine cones, hollow sticks and grass. Go outside with the kids and let them pick out other natural items. Come back in a couple of weeks and see how many insects have taken up residence in the house. This craft adds science as well, since the children can learn which bugs like to live in certain environments and try to figure out why.
