Auckland Mathematics Association 2011 Anna Martin Avondale College EXPERIMENTS AT LEVEL 7

 Pose a problem that will require an experiment to investigate  Write a plan for the experiment  Carry out the experiment and record data  Analyse the data  Answer the investigative problem  What could possibly go wrong? BASIC OVERVIEW

 Outline process for increasing understanding of new curriculum and associated assessment standards  Share planning for experiments at level 7  Increase understanding of different types of investigations involving experimental situations WORKSHOP GOALS

 NZC  Teaching and learning guides  Draft standard  Exemplar tasks (and annotated student exemplars)  Matrix  Workshops SYNTHESISING AVAILABLE INFORMATION

 Different types of experiments  How to pose a question for an investigation that needs an experiment  How to plan an experiment  How to explore data from an experiment  How to consider and use variability  How to write a report WHAT DO STUDENTS NEED TO LEARN

 Identify which of the following are experiments, and if so, what kind of experiment.  Describe what should you be looking for in the data. EXPERIMENT?

 What is the relationship between people’s “before exercise” pulse rates and their “after exercise” pulse rates? EXPERIMENT?

 What is the relationship between the height balls are dropped from and the height of the first bounce? EXPERIMENT?

 What is the relationship between the length and maximum circumference of carrots (or other fruit or vegetable?) EXPERIMENT?

 What is the relationship between people’s cubit lengths and their heights? (Cubit length is from elbow to tip of middle finger.) EXPERIMENT?

 Is the number of assessment standards (for all qualifications not just NCEA) offered by NZQA greater or less than 5 000?  How many assessment standards do you think are offered by NZQA? SURVEY TIME

TESTING PROCESSES  Myth busters episode on whether it is possible to shoot a ball out of the back of a car at the same speed the car is moving forward so that relative motion is zero.

 What was the investigative question?  What type of experiment was used?  How many trials were competed OR how many experimental units?  How was the data collected? What measurement tools were used?  What analysis was completed?  What conclusions were made? IDENTIFY AND DESCRIBE STEPS IN THE INVESTIGATION
