Presentation Transcript

  1. Mathematics and Science in Schools in Sub-Saharan Africa

  2. Scientific Method

  3. Lab: Scientific Method

  4. Lab: Scientific Method In this experiment, you will first make a “hypothesis”. Can you accurately calculate the height of an individual if you know their forearm length?

  5. Lab: Scientific Method Measure and record the length of each subject’s forearm. Measure and record the height of each subject.

  6. Lab: Scientific Method Data Chart

  7. Lab: Scientific Method Make a graph plotting forearm length vs. height.

  8. Lab: Scientific Method Measure and record the length of your teacher’s forearm.

  9. Lab: Scientific Method Using your graph, predict the teacher’s height. Test your hypothesis by measuring your teacher’s height.

  10. What is the Engineering Process?

  11. Engineering Process

  12. In the engineering process, aprototype is designed and constructed.

  13. The prototype is tested, refined and retested until the problem has been solved.

  14. Lab: Engineering Process

  15. In this lab, you will design and construct and test a “roller coaster”.

  16. The only materials you may use is a piece of rubber tubing and a ball bearing.

  17. Lab: Engineering Process Using just your rubber tubing, construct a roller coaster! The ball bearing must complete the whole course! Scoring: Each vertical loop (360°) = 10 Points! You may try as often as you like, best score counts! Failure is just a reason to start over more intelligently!

  18. In real life problem solving situations, scientists often do some “engineering” work while engineers frequently apply the Scientific Method!
