Lesson 5 – teacher plan – your sports

5 minutes- diamond 9 – students hsould think of 9 reasons why champions might win and put them in a diamond 9.

NOTE – HIGHER SHOULD DO EXTENSION ON HSW RATHER THAN EXPERIMENT ON THEIR REACTION TIME10 minutes- measure Usain’s time from video answer questions as to why it’s hard to measure(10 minutes Higher ability Extension – powerpoint and explanation accuracy and precision/ random and systematic errors. - Use kerboodle interactive investigation reaction times which examines errors)10minutes- read book p110 -111 this is a nice double page. 10minutes – measure reaction time use 30cm rulers to measure reaction times. Use table on this power point to work out time.

10minutes – plenary on Olympic sports for higher ability. - sports event interactive crossword for lower ability (could let the boys do it while the girls

are out of the room then the vice versa and time both groups for a bit of competition)

WHY DO CHAMPIONS WIN? In pairs think of 9

reasons

Put these into a diamond 9!
