Scientific Investigation
Taylor wanted to see if eating apples would help her do better on her classwork. The first day, she didn’t eat any apples. On day 2, she ate one apple; on day 3, she ate 2 apples; and on day 4, she ate 3 apples. Each day, she recorded the grades she got on her science work.
What is the independent variable?
What is apples?
This is the highest part of a transverse wave.
What is a crest
The maximum distance that a wave moves from its rest position.
What is amplitude?
A wave that moves perpendicular to the direction the wave travel.
What is a transverse wave?
If two waves pass a point in 4 seconds, what is the frequency?
What is 0.5 Hz?
Darius wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly.
What us the dependent (outcome) variable?
What is the distance it flies?
What is the lowest part of a transverse wave?
What is a trough?
The distance form one point on a wave to the same point on the next wave.
What is wavelength?
A wave that moves parallel to the direction that the wave travels.
What is a longitudinal wave?
What is one way to measure the wavelength of a longitudinal wave?
What is from compression to the next compression or from rarefaction to the next rarefaction?
How does fertilizer affect the growth of plants?
List three constant variables for this experiment.
What is type of plant, amount of water, amount of sunlight, soil, pot, environment.... ?
The part of a longitudinal wave where the particles of the medium are close together.
What is a compression?
The number of complete waves that pas a given point in a certain amount of time.
What is frequency?
What type of wave is a sound wave?
What is longitudinal wave?
What is one way to measure wavelength of a transverse wave?
What is from crest to crest or from trough to trough?
Why is it important to have only one independent (tested) variable?
What is so you know what caused your results?
The part of a longitudinal wave where the particles in a medium are far apart.
What is a rarefaction?
What is the unit of measure for frequency?
What is hertz (Hz)?
What is an example of a transverse wave that can travel through a vacuum?
What is light wave?
When amplitude increase what happens to the particles in a compression?
What is the compressions get closer together?
List the 6 steps (in order) of the scientific method.
What is
1. Observation
2. Problem/question
3. hypothesis
4. Experiment
5. Collect and analyze data
6. Conclusion
The material through which a wave travels.
What is a medium?
What happens to energy when amplitude increases?
What is energy increases?
A disturbance that transfers energy from one place to another without transferring matter.
What is a wave?
In science class, you listen to the sound of a tuning fork after it is hit against a cork. When you place the tuning fork to one end of a piece of wood and your ear to the other, you notice that the sound becomes high-pitched. What happened to the sound waves as they went through the wood?
a. They slowed, due to a high pitched echo
b. They slowed, due to more matter in the wood
c. They sped up, due to a higher frequency
d. They sped up, creating a higher wavelength
What is C. they sped up, due to a higher frequency?
