What is due tomorrow? • See me during lunch/after school if you need a form • Quiz will be on: • Rules • Class procedures • Graphing • SWOD vocab
Review Spag Lab: • Purpose/Question – what are you wanting to test? • Hypothesis – “if…then” statement • Materials – what you need • Procedures – step by step instructions • Variables – what you’re measuring/changing • Data – information, amounts, tables, graphs • Conclusion – “I found that when…this happened) • Further Questions – what more are you curious about?
What do you see? • Describe this…. • Qualitative Quality Descriptions, not measured, color, texture, smell • Quantitative Quantity Numbers, measurements, length, height, mass qualitative vs quantitative
With the person next to you: • Teach qualitative and quantitative only using your hands (no words)
Scientific TermsNotes 8/30/12 Get out a new page in notebook. Title and date it
1. Variable • A variable is: type of category you’re trying to measure (object, event, idea, feeling, time period, or any other category)
2. Dependent variable/Responding • Depends on other factors • The variable that is changing • Ex: • height of spag tower • test scores (Depends on different things)
3. Independent Variable/ Manipulated • Causes changes in other variables • Variable that stands alone • Isn’t changed by any other variables you’re measuring • Ex: • structure
Phrases to help remember • “The dependent variable depends on the independent variable” • “The manipulated variable manipulates how the responding variable responds” • “The (independent variable) causes a change in (dependent variable) and it isn’t possible that (dependent variable) could cause a change in (independent variable)”
Example #1: Find the DV & IV • Variables: Time spent studying & test score • (Time spent studying) causes a change in the (Test score) and it isn’t possible that the (Test score) could cause a change in (time spent studying) MIV RDV RDV MIV
4. Control • Anything that stays constant in an experiment • Ex:
