EXPERIMENTS AT LEVEL 7

Pose a problem that will require an experiment to investigate

Write a plan for the experimentCarry out the experiment and record data

Analyse the dataAnswer 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

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

Is the number of assessment standards (for all qualifications not just NCEA) offered by NZQA greater or less than 15 000?

How many assessment standards do you think are offered by NZQA?

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

USE WORRY QUESTIONS TO EVALUATE AND CRITIQUE
