Presentation Transcript

  1. Walk-In • Take out notebook • Turn to the BACK of your notebook. • Write today’s date on the left column underneath yesterday’s walk-in. • Answer in complete sentences: What did the Science Square puzzle have to do with science?!?

  2. Possible Answers • The puzzle showed that scientists have to persevere to solve problems. • When one way doesn’t work, a new solution has to be tried. • Looking at things differently is important to find new answers. • Luck can help to solve a problem too!

  3. The Work of Scientists

  4. To be a good scientist… • Be curious – wonder about things! • Be observant – notice with your 5 senses! • Be persistent – don’t give up, and keep looking for new solutions to a problem.

  5. Scientific Method • The Scientific Method is a set of steps scientists follow when doing an experiment. • It is the “greatest invention in science” because all other experiments could be done by following it!

  6. Scientific Method – Lab Report Format Glue the half-sheet into your notebook. Follow along as we look at some of the steps. We will do activities to learn the steps in the next few days!

  7. Analyze an Experiment Using the Scientific Method A scientist wants to find out if how old a person is affects how fast they can do a jigsaw puzzle. She has 6 people of various ages put together the same puzzle, and times each one of them.

  8. Here are the results: Age 5 7 8 10 11 13 Time(s) 75 62 61 77 80 85 Use the scientific method to identify: • Purpose/question • Hypothesis • Variables (independent, dependent) • Control • Materials • Results and conclusion

  9. A study was done to find if different tire types affect the braking distance of a car.

  10. The height of bean plants depends on the amount of water they receive

  11. The higher the temperature of the air in the oven, the faster a cake will bake.

  12. The amount of pollution produced by cars was measured for cars using gasoline containing different amounts of lead.

  13. A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly.

  14. Two groups of students were tested to compare their speed working math problems. Each group was given the same problems. One group used calculators and the other group computed without calculators.
