__**Here are 6 investigations from the Grade 9 TIPS4RM:**__ Carousel of relationships (good for the first week, recommended to do one investigation per day)

CBR investigation (good for the third week)

__**Other investigations**__ (please add your own ideas here)
 * Investigate the relationship between //exercise and pulse rate//. This can be combined with DPA.
 * Plant some seeds, e.g. beans, a week or so before classes start. Students measure //daily growth in the plants//. This could be extended by putting different groups of plants in different conditions, e.g. limited light vs a window
 * Barbie Bungee
 * //Fatigue vs. reaction rate//. A variation on this experiment. Have the subject vigorously clench and unclench his/her fist for one minute at a time, then test reaction rate after each minute.
