Ryan and Ava decided to see if the height of a ramp affects the distance that a ball travels. They used plastic balls and wooden ramps for each test. The height of the ramp was increased each time and distance traveled was recorded. The following table shows their results.

Based on the data, what would be the MOST reasonable measurement if they increased the height of the ramp to 16cm? (type answer using numbers and don't forget your unit of measurement)

When an experiment is designed, scientists test a relationship between a "cause" and an "effect". The "effect" is known as the ​ (a)   , of which the scientist measures and records the data. The cause is known as the ​ (b)   .

• independent variable
• constants
• control group

Organize the parts of this experiment in their correct categories.

Lisa and Ashley wanted to see how the type of music affects the growth of plants. They experimented for a period of 12 weeks. They purchased 6 Monstera deliciosa plants. Each plant was placed in a house with a constant temperature of 72 degrees. Each plant was placed in a south-facing window and received 6 hours of indirect sunlight each day. They watered each plant with 2 cups of water every Monday. Each plant was grown in the same type soil and received the same type fertilizer at the start of their experiment. For the first plant they played classical music 6 hours of the day. The 2nd plant they played rock music for the same amount of time. The 3rd plant they played rap music. The 4th plant they played Christian music. The 5th plant they played country music. The 6th plant did not have music playing. They recorded how tall each plant grew every Friday for the entire 12 weeks.

They recorded how tall each plant grew every Friday for the entire 12 weeks.

Based on the data provided, what would be the most appropriate hypothesis for this experiment?

• If classical music is played for a M. deliciosa, then it will grow the most.

• If country music is played for a M. deliciosa, then it will grow the most.

• If rap music is played for a M. deliciosa, then it will grow the most.

• If Christian music is played for a M. deliciosa, then it will grow the most.

• If rock music is played for a M. deliciosa, then it will grow the most.
