Mathematics Stage 5
Name………………………………………………………… ………………………………… Design Situation (The background or context)
The design situation is the story or the problem from where the brief comes from. Whenever designers spot a need for a product or item there is always a story behind it. What is your design situation?
The New South Wales Department of Education is attempting to address the problem of childhood obesity and inactivity by encouraging students to become more active in their daily lives. The Department of Education is promoting the sport of table tennis in all schools as a fun, easy to play activity that is not affected by weather.
The sport of Table Tennis has been enjoyed by people for over 100 years. However, the activity and the equipment have remained basically the same. To encourage participation in schools, the Department of Education is looking for a company that can re-invent the sport of table tennis and make it more appealing to students by offering a more modern design of the sport.

Activity 10 Measuring Activity Levels
Activity 10: Measure, display and explain the changes in your heart rate, resulting from a game of table tennis.
Method: Participate in a game of table tennis. Take your heart rate at different intervals (before the game, 2 minutes into the game, 5 minutes into the game, end of the game, 1 minute after the game, 2 minutes after the game)
Take your heart rate for 15 seconds and record. Multiply by 4 to get beats/minute and record.
Following the experiment, graph your results on a Cartesian place.
Explain why any changes in your heart rate occurred (muscles requiring oxygen to activate, oxygen carried in blood, heart responsible for pumping blood around the body, heart has to work harder when the muscles require more oxygen and blood to cope with exercise, decrease in need for oxygen when exercise is finished, fitter people have different shape graph to less fit people)
Use data to enter into microsoft excel and generate their own graph.
