1. Science Journal 10-1-14  Having too many people on the earth could someday be a threat. Fresh water, food supplies, and other natural resources could run out. How might overpopulation of the earth be prevented?

2. Getting Started With Science Fair

3. Four Question Strategy  START WITH AN INTEREST OF YOURS  THEN NARROW IT DOWN  THE NEXT COUPLE OF SLIDES WILL SHOW YOU HOW TO DO THIS Four Question Strategy: 1. Question 1 identifies the materials needed. 2. Question 2 results in possible dependent variables 3. Question 3 results in possible independent variables 4. Question 4 identifies how the effect will be measured

4. Start with a category of interest  Experiences – caring for a pet, foods you like & don’t, daily tasks  Hobbies – sports, video games, cooking  Interests – space, the environment  Current events – the election, school’s back 4

5. Identify interests and subcategories of them  Aerospace - Space – outerspace, black holes  Physics - sports – skateboarding, basketball  Chemistry - Cooking – baking – cookies  Zoology  Botany

6. Four Question Strategy “Okay I want to do a project on black holes”  Four Question Strategy  Q1: What materials are readily available for conducting experiments on (subject)?  Hmmm. None, go back to your list of interests

7. Four Question Strategy “Okay then I want to do a project on skateboards”  Four Question Strategy  Q1: What materials are readily available for conducting experiments on (subject)?  Skateboards, wheels, ramps, etc.

8. Four Question Strategy  Four Question Strategy  Q2: How do (subject)s act?  Roll far and fast  jump, turn, flip  One of these can be measured as the dependent variable.

9. Four Question Strategy Q3: How can you change the materials available to affect the action? 1.Brand of skateboard 2.Type of wheels 3.Wheel size 4.Material or age of wheel CHOOSE ONE FOR THE MANIPULATED VARIABLE KEEP ALL OTHER THINGS YOU COULD CHANGE THE EXACT SAME. THOSE ARE THE CONTROLLED VARIABLES.

10. Four Question Strategy  Four Question Strategy  Q4: How can you measure or describe the response of (subject) to the change?  MEASURE distance traveled  Measure speed  Measure height

11. Independent Group Work  WORK IN YOUR GROUPS TO COMPLETE THE READING AND QUESTIONS FOR THE ARTICLE ENTITLED “STUDYING PEOPLE QUALITATIVELY AND QUANTITATIVELY”  YOUR ASSIGNMENT IS TO READ THE ARTICLE AND COMPLETE THE 5 STOPPING TO THINK QUESTIONS.  COMPLETE THE GROUP INTERACTION SHEET, THEN GET STARTED.
