1. Day 5 Science 7 Goals: Continue process of observing, inferring and predicting. Continue process of observing, inferring and predicting. How do we sort data to help us understand what it means? (Graphing) How do we sort data to help us understand what it means? (Graphing)

2. Journal Entry – Observation and Inference Answer the following questions in your journal – refer to your notes if you need to 1. What is the difference between an observation and an inference? 2. Give an example of a QUANTITATIVE observation 3. An scientist observes that 14 Canadian geese are flying in formation heading South. What part of this is a quantitative observation? What part of this is a quantitative observation? What is a possible inference from this data? What is a possible inference from this data? What is a possible PREDICTION based on this data? What is a possible PREDICTION based on this data?

3. Plan for the Day Journal Entry while attendance is taken Journal Entry while attendance is taken Quick Formative Assessment ?? (15 minutes) - Can they sort out vocab and make inferrence / prediction Quick Formative Assessment ?? (15 minutes) - Can they sort out vocab and make inferrence / prediction Understand need for graphing data Understand need for graphing data Graphing – SALTPAD explained, distributed Graphing – SALTPAD explained, distributed Why? Why? How? Types and usage How? Types and usage Practice – Collect Data and then share data set Practice – Collect Data and then share data set Graph Start in class – Finish for Homework Graph Start in class – Finish for Homework

4. “CHECKS” – What’s the story Your groups will work with this next class period Your groups will work with this next class period Come with your timeline and evidence based Story on Wednesday Come with your timeline and evidence based Story on Wednesday

5. Assessment Time Show me what you know… Show me what you know…

6. Break Time 2 minutes in hall 2 minutes in hall Respectful time to stretch, use restrooms or get a drink Respectful time to stretch, use restrooms or get a drink

7. What is good? What is not so good? Discuss what every good graph needs

8. Handouts Each person needs 3 handouts to glue stick into the back of your Journal – Pages just BEFORE your Glossary Each person needs 3 handouts to glue stick into the back of your Journal – Pages just BEFORE your Glossary SALTPAD -- Guide to ensure quality graphs SALTPAD -- Guide to ensure quality graphs Types of Graphs – How to know which type of graph is best Types of Graphs – How to know which type of graph is best RECALL – Format for a lab report RECALL – Format for a lab report These are permanent tools to help throughout the year These are permanent tools to help throughout the year

9. SALTPAD S = Spacing  Equal intervals? S = Spacing  Equal intervals? A = Axis ( Independent Variable on x axis) A = Axis ( Independent Variable on x axis) L = Labels with units of measurement L = Labels with units of measurement T = DESCRIPTIVE Title T = DESCRIPTIVE Title P = Points Plotted Accurately P = Points Plotted Accurately A = Analysis __ SENTENCE(S) describing the Trend A = Analysis __ SENTENCE(S) describing the Trend D = Data Table Included? D = Data Table Included?

10. Analysis – What does this quality graph tell us? What does this graph show you? What can you infer from this data? What does this graph show you? What can you infer from this data?

11. Types of Graphs Focus discussion on Scatter Plot Focus discussion on Scatter Plot This is what they will be using today This is what they will be using today

12. Mini Experiment - Write Question and Your Hypothesis in Journal Question: Does the height of a person affect the length of their arm span? Does the height of a person affect the length of their arm span? Hypothesis: An educated guess/answer to this question. Write your hypothesis down now in Journal – There is no right or wrong hypothesis - -You will test it Write your hypothesis down now in Journal – There is no right or wrong hypothesis - -You will test it Example: “The arm span of humans is longer than their height” Example: “The arm span of humans is longer than their height”

13. Background Information Background Information Arm span = tip of finger to tip of other finger with their arms straight out Arm span = tip of finger to tip of other finger with their arms straight out 1 Meter = 100 centimeters 1 Meter = 100 centimeters

14. How will we do this? Materials Needed? Materials Needed? Is it important that we do things the same? Is it important that we do things the same? What are we going to do? What are we going to do?

No shoes, stand along wall to measure height No shoes, stand along wall to measure height Be aware of personal space and individuality. Be aware of personal space and individuality. At your table, collect information for each person, when done, share your information with others so you have at least 8 data points At your table, collect information for each person, when done, share your information with others so you have at least 8 data points

16. Data / Observations to Collect Name Height (cm) Armspan (cm) 1. 1. 2 3 4 5 6 7 8

17. Data / Observations to Collect Choose a variety of shorter and taller people Name Height (cm) Armspan (cm) 8

18. Use SALTPAD to help make a SCATTER PLOT of this Data Put Person’s Height on X-Axis (independent variable) Put Person’s Height on X-Axis (independent variable) Put Person’s Arm Span on Y- Axis (dependent variable) Put Person’s Arm Span on Y- Axis (dependent variable) Follow the guidelines of SALTPAD to put together your best effort GRAPH for next class Remember: “A” is for analysis.. After you make your graph write several sentences that EXPLAIN what the information tells you about our question. Was your hypothesis correct? “D” stands for Data – Attach your data table to your graph
