separation of mixtures
This practical task requires students to use methods of separation to separate a mixture of salt, sand, and iron filings. Students explain how they did this and the property of the substance that they used.

properties
viscosity
For this practical task students determine the viscosity of different household susbstances such as golden syrup, cooking oil, fruit juice etc. Students complete the experiment and construct a chart showing their results and observations.

marbles
Task: select a card to show how to control the variables of an investigation into the rolling distance of marbles on different surfaces. Assessment focus: controlling variables.
3

Keywords:
distribution
dot plots
graph construction
graph interpretation
work samples
Students conduct a statistical investigation about their prediction of the most common words used in English. They make graphs, describe their shape, and compare their own graph with ones that other students produce.

Keywords:
distribution
dot plots
fair testing
Students state what things will affect how far a cube will travel when flicked in the middle with a ball-point pen, and conduct an experiment to see what happens in practice.

qualitative data
selecting variables
table interpretation
tables
Students compare drawings of a healthy and unhealthy plant, collect data, and decide which data distinguishes them. This is a mathematics/science resource.

observation
sugar
For this practical students make observations about dissolving, and plan and carry out an investigation to find out what makes sugar dissolve more quickly.

variables
Task: Identify the variables for testing how fresh water and salt water affect rusting. Assessment focus: planning a fair test.

Keywords:
fair testing
light
plants
Students identify the variables to be kept constant, and the variable to be different, when they plan a fair test to show if green plants need light to grow.

erosion
tree planting
trees
Students are provided with a situation where the bank on the school field is eroding. They are asked to write a plan for a tree-planting programme that would help to slow down the erosion.

fair testing
liquids
practical
properties
viscosity
This practical task requires students to first plan how they could find out which liquid flows the best. Then they carry out their plan, record their results, and write a conclusion.

acceleration
experiments
fair testing
forces
physical inquiry
self assessment
Task: Predict which of three balls dropped from different heights will squash most, explain why, and design an investigation to test prediction. Assessment focus: acceleration and fair testing.

Keywords:
forces
physical inquiry
springs
This whole investigation requires students to find out how spring stretch is affected by different masses pulling on it. There is also a section for planning a similar investigation and a processing section using some provided data.
