Biology Unit 1 Test Study Guide

What is a hypothesis?

• Testing the hypothesis
• An explanation or answer that can be tested
• the study of life
• redoing experimentation and sharing results

What is an experimental group?

• Draw conclusions using the data
• Statements that predict, or tell us WHAT we expect to happen
• If-Then statement that can be tested
• A group where one variable is changed

What is science?

• combines observations and well-tested experiments into general explanations for phenomena, explain WHY
• 1) Genetic Code
• body of knowledge that uses evidence to explain the natural world through tests and predictions
• numerical data

What is step 1 of the scientific method?

• 5) Homeostasis
• Observations
• 3) Respond to environment
• It shows how numbers have changed over time.

What is step 2 of the scientific method?

• the group that does not receive the treatment
• 8) Made of Cells
• Statements that predict, or tell us WHAT we expect to happen
• Questions

What is step 3 of the scientific method?

• Statements that predict, or tell us WHAT we expect to happen
• Hypothesis
• A group where one variable is changed
• The variable that is changed

What is an inference?

• redoing experimentation and sharing results
• body of knowledge that uses evidence to explain the natural world through tests and predictions
• Hypothesis
• a logical interpretation based on what scientists already know

What is step 4 of the scientific method?

• 3) Respond to environment
• 5) Homeostasis
• Testing the hypothesis
• body of knowledge that uses evidence to explain the natural world through tests and predictions

What is the best format for hypothesis?

• If-Then statement that can be tested
• CAN BE CHANGED
• Draw conclusions using the data
• the group that does not receive the treatment

What is step 5 of the scientific method?

• Draw conclusions using the data
• If-Then statement that can be tested
• combines observations and well-tested experiments into general explanations for phenomena, explain WHY
• It shows how numbers have changed over time.
