EDUC 421 Science Methods for Elementary Teachers Pre-Test
1. What is a force?
A: A push or a pull
2. What is the difference between living and nonliving things?
A: Basic needs include air, water, and food. Plants require light
3. Name an Earth material that is a solid, one that is a fluid, and one that is a gas.
A: A sample answer can be the phases of water (ice, water, and water vapor)
4. What happens when you put the north pole of one magnet near the north pole of another magnet?
A: Like poles of a magnet repels
5. Name two living things that have a larva in their life cycle.
A: A sample answer can be flies and butterflies
6. What tool can be used to measure each of the following:
a. Temperature - Thermometer
b. Wind Speed - Anemometer
c. Precipitation - Rain Gauge
7. What does a graduated cylinder measure?
A: The volume of liquid
8. List four things plants need to live.
A: A sample answer could be air, water, food, and light
9. Explain the difference between a lake and a river.
A: A sample answer can be a river is longer than it is wide and usually has a current, while lakes are any shape and have no current
10. What makes sound (as in how is sound generated)?
A: Vibrating objects in the air
11. What main function does a flower perform for a plant?
A: Reproduction
12. Why are some natural resources considered renewable?
A: They are able to replenished as fast or faster than we use them
13. What is the metric unit of mass?
A: Grams
14. Explain how an environment change can cause a change in the food web. You may use an example to answer this question.
A: A sample answer could be there is a forest fire, cause owls to migrate to a new area. In this new area, there are less shrews and mice because of the increase in owls. Therefore there is more grass and more grasshoppers can survive.
15. Approximately how long does it take the moon to go through its phases?
A: A month
16. If two forces acting upon an object are unbalanced, what happens to the object?A: Changes in the motion
17. What is the general purpose of the skeletal system?A: Structure and support
18. What is the difference between a planet and a moon?A: Planets orbit a sun, Moons orbit planets
19. If an object has kinetic energy, the object must be doing what?A: In motion
