Objectives Content: I can demonstrate understanding of observations and inferences by identifying examples of each using a Power. Point. Language: I can write to identify examples of observations and inferences using “The Boy in the Water, ” and write to create my own examples of observations and inferences on an Observations and Inferences handout.

Let’s number Off • I will give you a number!!!! • Please record the number at the top of your paper (ISN).

Observations • Any information collected with the senses. • Quantitative – mesurable or countable » » 3 meters long 4 marbles 50 kilograms 35 degrees Celsius • Qualitative – describable, not measureable » red flowers » smells like fresh baked cookies » Tastes bitter • The skill of describing scientific events

Inference • Conclusions or deductions based on observations. • The process of drawing a conclusion from given evidence. Practice: • Observations: • I hear people screaming • I smell cotton candy, popcorn, and hamburgers • I see a lot of people • Inference = ?

Look at these two sets of animal tracks. List 3 OBSERVATIONS: Use sentence Stems below One observation I made is… Another observation… Last, Make an INFERENCE: Use sentence Stem below I infer that….

Think-Pair-Share Remember to use scientific vocabulary: • Observation • Inference OR Sentence Stems: • I observed… • I infer…

Activity Page • The Boy in the Water!!! • Look at the picture: • Discuss three observations with a partner • One observation I made… • Another observation… • Last, • Take 3 minutes to determine if the statements are observations or inferences. • Timer

Homework!!! • Observation and Inferences Handout OR • Make 10 Observations at home about your family, and then make an inference about your observation. • Example: • Observation: I walked in the front door and smelled lemon pledge. • Inference: My mom must have just dusted the living room.

Exit Ticket Make an inference based on the observation below: Observation: Mrs. Giger walked into class with a frown on her face and blood-shot eyes. Inference: I would infer that… Identify the statement as an observation or an inference: I feel the cold wind on my face. Create your own example of an observation and inference: Observation: Inference:
