  1. Hypothesis vs. Prediction

  2. Hypothesis • Includes 2 factors and how one factor will affect the other. • Must be able to set up a controlled experiment to test it (not take a survey) • Is a statement, not a question • Example: The more sleep a student gets the better he/she will be able to pay attention in class the next day.

  3. IMPORTANT!! • The results of an experiment cannot prove that a hypothesis is correct.The results either support or do not support the hypothesis. • In science, a hypothesis is supported only after many scientists have conducted many experiments and produce consistent results. • You can gain valuable information even when your results do not support the hypothesis.

  4. Prediction • An expected outcome of a future event • Have to “wait and see” • Example Highlands will win all their games this year.

  5. Let’s Practice • This year’s 8th grade will use more tissues than last year’s 8th grade. • Expensive nail polish will chip less than cheap nail polish. • Duracell batteries will last longer than Energizer. • My brother will have milk with dinner tonight. • Plants grow faster when given proper sunlight and water.

  6. More • Grandpa will live to age 96. • I will pass science this year. • Birds are guided by the spirits of dead antelopes. • Be tested? If the polar ice caps begin to melt, the amount of salt in ocean water will change. • Be tested? The higher you hang a bird feeder, the more birds that will come to it.
