DOCENT GUIDELINES

THIRD GRADE

DURATION: 50-60 minutes GENERAL INFORMATION: Do not spend more than 10-15 minutes for an introduction and instructions. Allow as much time for the hands on

component. If you are doing an art project, make sure you have all the materials readily available.

If you are teaching a new concept to third graders make sure they understand some of the vocabulary. You may need to repeat large words and have students repeat the word. Leave about 5 minutes to discuss what they did in the lab and urge them to develop a summary or conclusion of what they learned. Note: Background information is added information for the docent only.

present. Crustaceans, such as brine shrimp, are predominantly aquatic and have gills for respiration.

PROCEDURE:

1. Use the powerpoint on “Insects and other Arthropods.” Go over the different body parts. When you come to the Grasshopper stop, and give students the sheets called “Insect Anatomy.” Give each student a plastic grasshopper. Insects are some of the most successful land organisms. Insects bite humans, irritate skin, and sometimes cause disease. The insect body is composed of a head, thorax, and on abdomen with 6 legs. The head has a pair of compound eyes

2. Use the Insect Anatomy Worksheet and have the students color the correct area. Talk about a legend and how to use color to make the parts distinct. For example, color the word “head” red and then color the head portion of the grasshopper red.

3. Hand out the bag of organisms. Have the students sort into 2 groups Ask them to take out the non Arthropod (the lizard). It has a backbone and Arthropods are invertebrates, without a backbone. Then ask students to sort Insects and non insects. Insects have 6 legs. So take out the spider (with 8 legs) and centipeds (with many legs). The rest are all insects

4. Past out the envelops, and ask students to take out and lay the 3 sheets in front of them. If you have time, you can go over them using the powerpoint, pointing out on the key characteristics of each group. Have the students try and identify which group they belong to. Non Arthropod (not on sheet) Lizard (Vertebrate, Reptile) Arthropod Insects Ladybeetle, Beetle, Stag Beetle (Order Coleoptera) Butterfly (Order Lepidoptera) Grasshoppers, Praying Mantis ( Order Orthoptera)

Eggs: Monarch butterflies lay their eggs on individual milkweed plant leaves which are specifically chosen by this species for this purpose (host plant). The process from egg to adult butterfly is about 6 weeks. Caterpillar (Larva): The caterpillar hatches from the egg in 3-12 days. As soon as it emerges, the caterpillar begins to eat milkweed leaves that are toxic to many insects but not to the caterpillar. Chrysalis (Pupa): The caterpillar encases itself in a beautiful jade green shell with gold markings. This coloration camouflages the shell from birds while inside the caterpillar begins the transformation into a butterfly. Adult (Butterfly): When the butterfly is mature it emerges from the chrysalis. The Monarch’s wings are folded up and they must be pumped up by the butterfly in order to straighten them. Once the wings are dry the butterfly can fly. After 2 to 5 weeks the adult butterfly will reproduce and lay eggs. Life Cycle of a Luna Moth Eggs: An adult female moth typically lays around 200 eggs in small groups of 6-10 eggs on the underside of leaves. After about ten days on the underside of leaves. After about ten days, small caterpillars will eat their way out of the tiny eggs. Caterpillar (Larva): The newborn caterpillar constantly feeds, eating several leaves daily. As it grows the caterpillar will molt, crawling out of its old skin having formed a fresh, new skin underneath. It will grow to its full size of about 2 inches (5 cm) long. Cocoon (Pupa): The caterpillar pulls a leaf around itself and spins a cocoon, a protective covering, winding thread around its body. After a week, the caterpillar becomes a pupa where it will transform into a moth. Three weeks later, the adult moth will push itself free. Adult (Moth): At first, the Luna Moth’s wings are soft and wet. I must immediately find a place to hang and dry its wings before it can fly away. An adult moth does not eat, living for about one week during which it will find a mate and reproduce.

3. Have the students make a monarch “life cycle wheel.” Stress to use the models to make the Monarch realistic with color and patterns.
