LIFE ON EARTH

1. LIFE ON EARTH • There are 5 primary groups of life called kingdoms. • Monera (bacteria) • Protists (single-celled) • Fungi (yeast, mushrooms) • Animals • Plants • We are going to continue to study the animal kingdom.

2. So far we have investigated many different types of living organisms: paramecia, yeast, brine shrimp, snails, and several plants. They are all different, but even so, they all have some things in common. • What are some of the things they have in common?

3. Now we are going to study the largest group of organisms on Earth. In fact there may be more species (different kinds) of these organisms on Earth than all the other species put together. They are found on every continent, in the air, and in the freshwater world over. They are so important that many other species could not survive without them. Because of this, many scientists feel that they rule the planet. What group is it?

4. WORD BANK • Adaptation-Structures and behaviors that increase an organism’s chances of surviving and reproducing.

6. LEARNING GOAL • I will learn the structures and adaptations of insects. • I will observe structures and behaviors of a multicellular organism called a Madagascar Hissing Cockroach (insect). • I will design and conduct an experiment (safely and appropriately) to determine environmental preferences of an insect (roach)

7. Label the 3 body parts. What other structures can you label that let you know this is an insect?

11. DRAWING • Let’s draw a diagram of an insect and label the main parts.

14. REVIEW

16. ADAPTATIONS • Insects, like other organisms, have structures and behaviors that help them survive. Structures and behaviors that increase an organism’s chances of surviving and reproducing are called adaptations. No other group or organisms has a greater variety of adaptations than insects. Let’s consider a mosquito as an example.

17. MOSQUITOES • What do you know about mosquitoes? • What do they eat? • How do mosquitoes find their pray even in the dark? • How do mosquitoes extract their measure of blood? • When do you usually notice a mosquito bite, at the time she is biting you or after she has left?

18. ADAPTATIONS • Everything about the piercing mouthparts of the female mosquito is adapted for tapping blood. The proboscis, often incorrectly called the stinger, is equipped with specialized tools for the job. It has sharp “scalpels” for cutting through skin, “clamps” to hold the wound open, and a strawlike mouthpart the mosquito inserts into a capillary to suck up blood.

19. ADAPTATIONS • Mosquito saliva has chemicals that keep blood from clotting, so that its meal will not be interrupted. The saliva also contains pain killers. You usually don’t feel anything until a few minutes later, when the pain killer has worn off.

23. COCKROACHES • For the next few classes, you will be studying the adaptations of a live insect. Relatives of this particular kind of insect have been on Earth for the past 400 million years, long before the first dinosaurs roamed Earth. This organism has some highly effective adaptations that have allowed it to survive for that long. The insect we will be studying is the cockroach!
