1. Inferences & Observations
Day 3

2. Inference/Observation Input
Using your five senses to take note of and observe your surroundings
Logical interpretation based upon prior knowledge and experience
Based upon observations

3. Let’s practice making inferences! Output
The next three slides show some fossil imprints that were found during a archeological dig. We’re going to record some observations and then make some inferences about what may have happened millions of years ago….

4. Make 3 observations about the picture
Make 1 inference about what may be happening in this picture

5. Make 2 more observations
Make 1 more inference

6. This time make only observations…

7. What do you think happened?
Please write a short story describing what you think happened to the creatures in our fossil evidence

8. Types of Observations Input
Quantitative Observation- Observation using numbers
Qualitative Observation-Observation without numbers
Lets Practice- You will be shown a picture on the following slide. Please write 2 quantitative observation and 2 qualitative observations.

9. Output

10. Homework
Please work independently to complete the practice problem. If you need help, please raise you hand. 

11. Inquiry foldable Day 4
Your will need to follow directions and fill in the following information in your foldable. Each slide is a new flap in your foldable. The titles of the slide should be the part that is hanging out of each flap. Please raise your hand if you have a question.

12. Testable Question
A specific question where one variable is changed. Results can be observed and measure.
Measureable
One variable
Specific
Does (independent Variable) affect (dependent variable)?
Examples-
Does exercising affect your heart rate?

13. Hypothesis an “educated guess”
can be written -“If..., then..., because...” statement
Prediction
Example
If an individual increases his/her activity level, then their heart rate will increase because the body’s muscles (cells) will require more oxygen to function at a higher level. A faster beating heart will increase blood flow; thus, allowing an increased concentration of oxygen to reach the cells in need.

14. Variables Independent variable that is changed “if” -in the hypothesis
“cause” in a cause and effect relationship
Example
The activity level (resting, walking, running)
Dependent
Results/Measurement
factor you measure to gather results
“then” in the hypothesis
“effect” in a cause and effect relationship
Example
The person’s heart rate

15. Identify the Variables
independent
variable
If a student chooses to not study, then they will earn a poor grade.
If you drink Gatorade before a soccer game, then you will score more goals.
If you increase the mechanical advantage of a pulley system used to move an object, then the input force becomes less.

16. Control or Control Group
The most normal situation
something that is not manipulated
a neutral point of reference for comparison –baseline for comparison
Example
The resting heart rate represented the baseline heart rate to which any increase in activity level was compared to.

17. Constants
Factors in an experiment (both in the experimental and control groups) that are kept the same and not allowed to change
Examples
One minute was consistently the amount of time allotted to perform the necessary activity
The type of activity performed
The stopwatch used during data collection
The method used to measure the heart rate

18. Lets Practice… The Experiment
A shopping mall wanted to determine whether the more expensive “Tough Stuff” floor wax was better than the cheaper “Steel Seal” floor wax at protecting its floor tiles against scratches. One liter of each type of floor wax was applied to each of the 5 test sections of the main hall of the mall. The test sections were all the same size and were covered with the same kind of tiles. Five (5) other test sections received no wax. After 3 weeks, the number of scratches in each of the test sections were counted.
