Main Curriculum Tie:
Background For Teachers:
Insects are just one type of invertebrate. All insects have three body parts and six legs. If it does not have three body parts and six legs, it is not an insect. Worms do not have any legs. They are not insects. Ticks have eight legs. They are arachnids (spiders). They are not insects. Millipedes and centipedes have many, many legs. Pill bugs/potato bugs/rolly-pollies have many body segments and many legs. They are not insects either. They are crustaceans. Once again, insects have six legs and three body parts. If it does not have six legs and three body parts, it is NOT an insect.
Student Prior Knowledge:
Intended Learning Outcomes:
Step 2. Find out through discussion or journal writing what the students already know about insects. Use the pictures from the Internet site or another source for reference and the rest of the activity.
Step 3. Using students' prior knowledge, build on what they know about insects and what they observe from the pictures. Ask questions about their observations. List these on the board. They should include the following:
Step 4. Ask the children how they think that insects are classified.
Step 5. Using the Internet pictures or another source, have students work in groups. First they will come up with a classification system that their group will use to classify a group of insect pictures. Remind them that they should be able to defend their method of classification. Then give each group a set of six insect pictures. Using their simple insect key, (such as wing size, mouthpart type) students will classify their pictures. Have each group share their photos and their classification system.
Step 6. Take the children on a walking field trip with bug nets and jars. Have them collect any invertebrates (animals without backbone: insects, worms, potatobugs, etc.) they find and put them in the jars. Be careful about catching bees or other dangerous animals. Require the students to treat the animals respectfully. Take the collected invertebrates to the classroom for the children to view.
Step 7. Using what they now know about insects, have the students classify the collected animals as either insects or non-insects. They should use a simple insect key that they have created. Have groups rotate around the room looking at each other's data and classification systems.
Step 8. Next, encourage the students to examine the mouthparts of the various insects and classify them accordingly.
Step 9. Return the invertebrates to their appropriate habitats.
Step 10.Have each students draw a Utah insect using the information they have learned. They must decide what their insect eats and draw appropriate mouthparts. The isects must have three body parts and six legs. Display the finished drawings in a center filled with resource materials about insects.
