Multiple Choice

A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The independent variable is

• the male alligators

• the gender of the alligator

• the temperature

• the incubator

Multiple Choice

Multiple Choice

What is a correct hypothesis for this testable question?

Testable question: Does changing the amount of water affect the growth of plants?

Materials:

2 sunflower plants

2 pots with same soil

10oz water daily

Rock music and headphones - 1 plant

1 plant no music or headphones

ruler

• If we use rock music then the plant will decrease because plants shrink.

• If we use rock music then the plant will grow more in size.

• If we use rock music then the plant will grow more in size because rock music stimulates the plant to grow more.

Multiple Choice

What is a correct hypothesis for this testable question?

Testable question: Does changing type of surface effect how far a ball will roll?

Materials:

2 rubber balls

concrete surface

dirt surface

ruler

• If we roll the ball on the dirt then the plant will roll longer because it can roll longer on a rough surface.

• If we roll the ball on the dirt then the plant will roll shorter because it can roll longer.

• If we roll the ball on the dirt then the plant will roll shorter because it the bumps of the dirt surface make it harder for the ball the roll farther away.
