25 points!! Question 2

Now follow these directions to classify the insect specimens. Start by putting on your

gloves and goggles. Then, using the forceps, remove all 15 insect specimens from

the jar and put them in the petri dishes.

Be very careful when removing the insects. Wings and body structures can be easily

damaged. Choose 10 insects that you want to classify using the dichotomous key,

and put the remaining insects back into the solution.

The dichotomous key that came with the Edmentum lab kit has descriptions and

"refer to" numbers. Start at Space 1, and determine whether your specimen has

wings. Jump to the "refer to" space to further classify the organism. Continue until

you reach the insect's order. If you're not using an Edmentum lab kit, follow the

instructions for your specific dichotomous key.

Now follow these steps to further classify each specimen. Write your notes in the

chart using the exact wording from the dichotomous key. An example is given in the

chart.

1. Use the magnifying glass to identify the body parts of each insect, such as the

mouth or wing structure. Use the microscope on the lowest or second-lowest

setting to observe the body parts of small insects.

2. Place the insect in the petri dish lid, and then place it on the microscope. (The

bottom part of the petri dish is too tall to fit under the microscope. Adjust the

upper microscope light instead of the base light. Then move the dish around

until you can see the specimen.)

3. In some cases, an insect's metamorphosis will determine its final order. Use

credible websites to look up the metamorphosis of insects belonging to

different orders, and match your specimens accordingly.

4. After you have studied all 10 insect, make sure your classification chart is

complete and that you have used the exact wording from the dichotomous key.
