Quick Get-To-Know-You Around your table, say your name and favorite ice cream flavor. Be ready to meet another table and introduce each other!

Walk-In Take out notebook, folder and pencil box and agenda. Answer in sentences: Why are quantitative observations often better to make in science than qualitative ones?

Possible Answers Quantitative observations are facts based on measurements and counting. More than one person can get the same answer. They can be agreed on.

How Do Scientists Work? Watch this video clip about how scientists work. Be ready to discuss afterward what the scientist did to be successful in his work. Did he solve the problem he set out to do?

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.

Scientific Method A set of steps scientists follow when doing an experiment. Considered the “greatest invention in science” because all other discoveries and inventions came from following it!

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

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 predicts that kids keep getting faster as they get older. She has 6 kids of various ages put together the same puzzle, and times each one of them.

Here are the results: Age 5 7 8 10 11 13 Time(s) 75 68 61 59 73 85 Use the scientific method to identify: Purpose/question Answer: Does how old a person is affect how fast they do a puzzle?

Here are the results: Age 5 7 8 10 11 13 Time(s) 75 68 61 59 73 85 Use the scientific method to identify: Hypothesis (educated guess) Answer: If kids are older, then they will be faster because they have more practice.

Here are the results: Age 5 7 8 10 11 13 Time(s) 75 68 61 59 73 85 Use the scientific method to identify: Variables Independent – What did she change? Answer: age of the student Dependent – What did she measure? Answer: how fast they did the puzzle

Here are the results: Age 5 7 8 10 11 13 Time(s) 75 68 61 59 73 85 Use the scientific method to identify: Control – What was kept the same (so it is a “fair” experiment)? Answer: same puzzle for everyone

Here are the results: Age 5 7 8 10 11 13 Time(s) 75 68 61 59 73 85 Use the scientific method to identify: Materials Answer: puzzle, stopwatch

Here are the results: Age 5 7 8 10 11 13 Time(s) 75 68 61 59 73 85 Use the scientific method to identify: Results and conclusion Answer for results: Kids got slower as they got older, then they got faster. Conclusion: Hypothesis was NOT supported. Maybe kids get bored with puzzles, then they get more competitive again as they get older.

Guided Practice: Now YOU try it! With people at your table, discuss how you would do an experiment on the following question: DOES THE FLAVOR OF AN ICE-CREAM AFFECT HOW FAST IT MELTS? Include hypothesis, variables, and procedure.
