Students pose a question for an investigation about favourite sports. They then construct a table that could record the results.

Students plan aspects of a statistical investigation about the most common birth month in Year 8, including designing a table for data collection.

Students plan how to do a statistical investigation about a question that has been posed, and think about how they will collect their data.

Students are required to critique a survey and design another useful question to be included.

Students read the description of a number of surveys and explain why the sample is biased.

Students conduct a practical, statistical investigation. They decide on a Topic and question, conduct the survey, complete the tally chart, construct a bar graph of the major ideas and make statements about the results.

Students conduct a practical, statistical investigation. They decide on a question, categories, conduct the survey, tally and graph the results on a bar graph.

Students conduct a practical, statistical investigation. They decide on the question to investigate, conduct the survey, complete the tally chart, and construct and label a bar graph.

Each student designs a question and an associated scale to record other students' attitudes to mathematics.

A council survey is to be sent out, and students are asked to give examples of representative samples.

Students are required to give reasons why the samples used to survey New Zealand school students on their favourite sports, may not be representative of the population.

Task: Plan a fair test to see if adding salt water to water affects how long it takes to freeze. Assessment focus: managing variables.

Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. This is a mathematics/science resource.

Students decide on the best sample of students for a given survey and answer a multiple choice question. They also answer a question on sample size for best accuracy.

Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. They draw conclusions from the data. This is a mathematics/science resource.

Students compare drawings of a healthy and unhealthy plant, collect data, and decide which data distinguishes them. This is a mathematics/science resource.

Students are provided with drawings of three methods to collect gases and the characteristics of four gases. Students match the gases with the method of collection that would need to be used.

Students estimate and tally the number of each activity their partner completes in 30 seconds. They then identify the best estimate.

For this practical task students plan and carry out a fair test to determine which of four different cups will keep water the hottest over 10 minutes. Students are also required to graph their results and write a conclusion.

Task: Look at the arrangement of fibres for four different paper towels, arrange an appropriate sequence of instructions, carry out the instructions and then communicate the data in an appropriate graph that will help answer the question. Different elements of the nature of science are embedded throughout the tasks. Assessment focus: planning and carrying out a fair test, using evidence to answer a question.

Students predict how a cube will travel when flicked in different positions, and conduct an experiment to see what happens in practice.

Plan an investigation to find out which of two students' predictions is correct, and identify how to recognise what a result would look like. Assessment focus: identifying what to measure or compare to answer a science question.

Select the correct pair to set up a fair test. Assessment focus: controlling variables.

In this practical task, students collect data on the number of people in cars passing the school. They then record this, in a table and use the information to make a prediction.

For this practical task students collect time-series data on the change in water temperature in a container at regular time intervals. Students are also required to display their results on an appropriate graph.
