1. Prediction: to tell something before it happens 2. Hypothesis: a possible answer to a question based on gathered information.

DO NOW What Is Science?? - In your own words, write down any ideas or thoughts to explain what science is all about! -Take out homework if you did not.

Do NOW: 9/2/ Turn in LAB SAFETY CONTRACTS (BACK PAGE ONLY) to the basket on the silver cart. 2. Add Lab Safety RULES (front page) to your notebook.

Observations vs. Inferences “YOU CAN OBSERVE A LOT JUST BY WATCHING.” -YOGI BERRA.

 Observation is describing an object using your five senses (sight, hearing, touch, smell, & taste) or measurement (numbers).

By Mrs. Gilmore & Ms. Titus. What is an observation? Answer: When you observe, you become aware of something using one of your senses. Your five senses.

 There isn’t a single scientific method, but there is a style of investigation that can be called scientific methodology.  There are 5 main parts that.

9/9/14 Objective: What is discovery science? *Take out HW, keep for now Do Now: Write down 3 observations (things that you can actually see that are important.

3. Gather background information (finish)  Jefe: Read interviews out loud to your group  Discuss the most important piece of information from each interview.

 Read through all of the procedures on the lab handout before looking at the following pictures.

Understanding Observations

Notes: Observation, Inference, Prediction. Observation: Using your five senses to describe something Examples –There are 12 black desks in the room. –There.

Observation vs. Inference

Using one or more of your senses to gather information about an object or your surroundings. What are the senses we use in science class? Sight Touch.

LAB SAFETY LESSON

Mystery…in the Lab

Crime Scene Walk-Through  Pictures included on following slides for absent students

1. Observations  View the crime scene photos & write as many observations as possible.

Analyze the observations  Qualitative Observations: Describe characteristics (color, appearance, sensations)  Quantitative Observations: Describe numbers of things (how many, how much, times)  Opinions: Describe personal feelings about something (smelly, scary, gross, yummy, etc.)

2. Questions  Discuss & Record 3-5 observable questions the group has about the crime scene. (Questions must be able to be answered by observing the crime scene)

3. Gather background information  Read interviews out loud to your group  Identify the most important piece of information from each interview & record that info in a few bullet points on the handout

4. Gather evidence  Materials Manager: The pH of the blue liquid is 8. What does that mean? (Complete on handout)

5. Make inferences  Inferences = explanations based on observations  Make inferences about what you think happened to Jeremy.  Come up with a 1P explanation of what happened from start to finish (complete as #5 on handout)
