Biology Unit 1 Test Review: Scientific Investigation

What should you do if your hypothesis is rejected?

• Change your data to math your hypothesis

• Throw out your hypothesis and data

• Use the data to formulate a new hypothesis

• Change your hypothesis to match your data

Which is the best hypothesis?

• Mr. Snow is the best teacher ever

• If Ms. Fowler makes learning fun, then my tests scores are better.

• Ms. Backus likes Biology, so she must be smart

• If Mr. Guillen teaches Oceanography, he must swim well.

A proposed explanation made on the basis of limited evidence beginning an investigation is a:

• theory

• hypothesis

• dependent variable

• independent variable

A variable that is being tested, changed or manipulated is the:

• dependent variable

• control group

• independent variable

• experimental group

The variable that is measured is the:

• control group

• experimental group

• independent variable

• dependent variable

The group that receives NO experimental treatment:

• experimental group

• control group

• out of control group

• rock group

According to the graph, the highest metabolic rate is found in:

• reptiles

• amphibians

• mammals

• birds

What represents the independent variable?

• Age of the trees

• Forest A

• Forest B

• Average Thickness of Rings

What is the independent variable in the graph?

• sun plant

• shade plant

• rate of photosynthesis

• light intensity

Many supported hypotheses grouped together that have predictive value make up:

• Hypothesis

• Theory

• Lab Report

• Control Group
