  1. DO NOW You observe that every time you drink cola for lunch, you seem very antsy and distracted in your 6th period class. Design a hypothesis to question this scientific phenomena.

  2. A Possible Answer • If soda affects attention levels in students, then drinking soda for lunch will increase a student’s distraction levels.

  3. Writing a Hypothesis Points to remember when writing a formal hypothesis.

  4. Point One • Hypothesis must be written in an “If…, then…” statement • Example, If the amount of television watched affects science grades, then the more television a student watches, the lower their grades.

  5. Point Two • The IF part of the statement is what you’ve observed already. • You should also mention the relationship between the variables. • Example - If the amount of televisionaffects science grades…

  6. Words You Can Use Here • Influence • Affect • Shape • Change • Mold • Manipulate • Relates to • Impacts • Correlates with

  7. Point Three • The THEN part of the statement is what you are predicting is going to happen. • You should write your educated guess here. • Example - then, increasing the television a student watches will decrease their grades.

  8. Let’s Practice • I’ll give you the variables, you write the hypothesis in an If…then, … statement. • ONE: • MV – amount of fertilizer • RV – plant height

  9. A Possible Answer • If the amount of fertilizer given to a plant affects its overall growth, then the more fertilizer given, the higher the plant will grow.

  10. TWO: • MV – amount of exercise • RV – health of pre-teens

  11. A Possible Answer • If the amount a child exercises influences their health, then the less a child exercises, the more they will put their health in danger.

  12. THREE • MV – temperature • RV – growth rates of bacteria

  13. A Possible Answer • If temperature manipulates the growth of bacteria, then bacteria colonies will increase with a rise in temperature.

  14. Interpret this graph and write a hypothesis

  15. A Possible Answer Based on the data, “If video games have no influence on violent acts in adolescents, then the number of violent acts in children will not be affected with the introduction of new video games.”
