What is observation? Observations are made in science. They are made by using: The 5 Senses Taste Smell Touch Hear See I will ask students tell me what the five senses are. Students will be asked to take down notes on their graphic organizer that will be handed out as a worksheet.

Two types of Observation Qualitative Quantitative Qualitative = “L” for looking Quantitative = “N” for numbers QUANTITY VS QUALILTY

1. Qualitative Observations Hard to measure Describes the qualities of something Color Taste Sound Texture **Facts not opinions. More note taking will continue

2. Quantitative Observations Mathematical aspect Can be expressed in numbers Can be counted or measured Amounts Temperature Mass Length Allow us to communicate specifics Tools are used to communicate data Observations are collected in data tables increase accuracy & precision More notes

Inference Drawing a conclusion based on data and observation 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 = ? Inference= I might be at a state fair, or a local carnival. Maybe a birthday party for a friend or sibling.

Observation Vs Inference That plant is extremely wilted. The car stopped running The Diamondbacks are leading their division That plant is extremely wilted due to a lack of water. The car stopped running because it was out of gas. The Diamondbacks are leading their division because they are playing well right now. Observations lead to well informed inferences

When to use observation & inference… During experiments, record observations NOT inferences Inferences may be used when writing the conclusion in your lab report. Finish taking notes for the day.

Observation or Inference There is a representation of a face on one side of the coin. The Latin word "Dei" means "God.“ The coin was made by deeply religious people. The date 1722 is printed on one side of the coin. The coin was made in 1722. The face on the coin is a representation of the nation's president. Students will be asked to determine if the numbers 1-6 are observtions or inferences. This will be done aloud as a class.

Observation or inference? Let’s …. Look at the picture & decide if the statement is an Students will be asked to determine if the pictures facts are observations or inferences. This will be done aloud and as a class. This will also help modifiy for students in class who are have low reading skills and are more proficient with understanding visual aids.

There is smoke in the room. Observation Observation

Sheldon left a hot pocket in the microwave too long creating it to burn and smoke up the apartment. Inference Observation or Inference ? Why is it an inference? Can you come up with another inference as to why there is smoke in the apartment?

Lucy the elephant was built by the big apple Circus Inference Inference !! We do not know this to be fact just from looking at the picture

Lucy has two white tusks Observation Why kind of observation is this and why? Quantitative because you are counting the number of tusks she has

Lucy’s real name is lucille the elephant Inference INFERENCE!! WE CAN NOT COME TO THIS CONCLUSION WITH OUT FURTHER EVIDENCE. EXTRA INFO: LUCY THE ELEPHANT WAS ACTUALLY BUILT in 1841 It was built in Philadelphia. She was built as a gimmick to get people from Atlantic city to move to a smaller out skirt town. Than Lucy was sold to a physician who added four bedrooms and he lived there with their family. Than she made into a tavern but that didn't’t really last. In 1962 Margate NJ condemned Lucy. Lucy was going to be torn down but people rallied together to get her moved, Lucy July 20th 1920 to a new location two blocks away and she is now used a travel icon in NJ and people go to visit her and explore her amazing architecture. Lucy is now a national landmark! Wouldn’t think that just from an observation right?

Look at these two sets of animal tracks. List 3 OBSERVATIONS Make an INFERENCE Students will move on to the tricky tracks activity. Students will work within their groups to list three observations and 1 inference about the tracks they see in the picture.

Now what do you think? Make 3 OBSERVATIONS Make an INFERENCE Students will move on to the tricky tracks activity. Students will work within their groups to list three observations and 1 inference about the tracks they see in the picture. These observations and inferences can be modified from their existing lists Make 3 OBSERVATIONS Make an INFERENCE
