Explain why a frog is considered a living thing whereas a computer is not.

Correct Answer: A frog is considered a living thing because it is capable of carrying out all of the life processes such as food getting, digestion, absorption, growth repair, response, reproduction, etc... A computer is capable of response and movement, but it cannot carry out all of life activities.

Your friend insists that plants are not alive because they do not move. Give specific examples to explain why your friend is wrong.

Possible Answer:

One example students might cite is the fact that plants will move toward sunlight. Another example is that plants such as the Venus flytrap can move in response to the stimulus of insects touching their leaf hairs. Also, animals that don’t move any more than some plants (e.g. sponges, etc.).

Is it Alive?

Teacher’s Guide

Materials:

Yeast

sugar

sand grains

paper towels

small containers of water

magnifying glass/microscopes

Procedure: Each student is given 1/2 tsp. of each material (sand and yeast) without being told what he or she has received. Each student will observe and describe each of the materials. Students may organize in small groups (2 or 3) to discuss their observations and share what they have learned. They will record and summarize their comparisons and contrasts made. Students will plan and experiment individually or with a partner to determine whether each substance is living or non-living based on six criteria for living organisms below. Make a conclusion supported by evidence from experiment.

Criteria for living organism:

1. Made of cells

2. Needs food and water to develop and live

3. Grows

4. Can reproduce

5. Responds to environment

6. Adapts to environment

Is it Alive?

You have been given 1/2 tsp. of 2 different materials. In the space provided below or on a separate paper write a detailed description of observations of each material.

When you have completed the written description you may assemble in groups of 2 or 3 to share what you have learned. In the space below or on a separate paper record and summarize the comparisons and contrasts made.

On your own or with a partner plan an experiment to determine whether each substance is living or non-living , based on the six criteria for living organisms. Have plan approved by teacher before proceeding with experiment.

What happened? Give specific details.

Make a conclusion supported by evidence from your experiment.

Are all criteria apparent from your observations?
