  1. 09-08-14 • Turn in Do Nows • Lab Procedures • Please record today’s schedule & homework in your planner & answer the following on your Do Now sheet. • Explain the difference between qualitative & quantitative observations. Schedule Do Now • None Homework

  2. 09-08-14 Learning Objective I can write a detailed procedure for a lab investigation.

  3. Which of the following are observations and which are inferences? • A man was fishing from a dock. • 2. The lighthouse is on land. • 3. There is a tackle box on the dock. • 4. A fish bit the dock. • 5. A man was eaten by a fish.

  4. The Lab

  5. Purpose/Problem Statement: • Do double stuf Oreos actually have twice as much filling as a regular Oreo?

  6. Materials: • 1 double stuf Oreo • 1 regular Oreo • Triple-beam balance • Ruler • Calculator

  7. Procedure: • Gather lab materials. • Carefully twist off one side of the cookie from both Oreos. • Measure the mass (g) of the cookie with no filling on it for both cookies using the balance. • Record the number of grams in the data table.

  8. Procedure: • Measure the mass (g) of each cookie with the filling on it using the balance. • Record the number of grams in the data table. • Using a calculator, Calculate the mass of filling by subtracting the cookie mass (g) from the cookie + filling mass (g). • Record the difference (g) in the data table.

  9. Procedure: • Record the results from 3 other groups. • Using a calculator, calculate the average mass (g) of filling and record this value in the data table. • Clean up!

  10. 09-09-14 • Oreo Lab: Data Table, Variables, Hypothesis & Data Collection • Please record today’s schedule & homework in your planner. • List 3 things that you need to include when writing a detailed lab procedure. Schedule Do Now • None Homework

  11. 09-09-14 Learning Objective I can correctly identify variables & write a hypothesis for a lab.

  12. Identification of Variables: • Manipulated: Type of Oreo – double stuf or regular. • Responding: The mass (g) of the filling. • Controlled: • Triple-beam balance • Method used.

  13. Hypothesis/Prediction • Write a hypothesis using the IF, THEN, BECAUSE format. • IF the filling of double stuf and regular Oreos is measured THEN the double stuf Oreo will have twice the amount of filling of the regular Oreo BECAUSE Nabisco isn’t allowed to falsely advertise their cookies.

  14. Got Stuf? – Regular vs. Double Stuf

  15. 09-10-14 • Oreo Lab: Analysis & Graphs • Please record today’s schedule & homework in your planner. • What 3 key words must be found in a hypothesis? • Write a hypothesis for the effect that studying has on a student’s grades. Schedule Do Now • None Homework

  16. 09-10-14 Learning Objective I can analyze & graph the results of a lab.

  17. Regular Oreo Data

  18. Double Stuf Oreo Data

  19. 09-11-14 • Oreo Conclusion • Please record today’s schedule & homework in your planner. • What are the 3 types of variables that should be identified in any lab investigation? Schedule Do Now • None Homework

  20. 09-11-14 Learning Objective I can write a complete & detailed conclusion for a lab investigation.

  21. 09-12-14 • Pre-Test: Earth’s Geosphere • Book Check-Out • Textbook Scavenger Hunt • Please record today’s schedule & homework in your planner. • What was your favorite part of the Oreo cookie lab? Explain why. Schedule Do Now • Scavenger Hunt Homework

  22. 09-12-14 Learning Objective I can find and use the various resources of my textbook.
