ISLAND ADVENTURES LEVELLED WORK HOW SCIENCE WORKS You have to design and carry out an investigation to find out what environmental conditions to keep the woodlice in. The ecologists have begun taking samples of the animals and plants from the island. They want to take the organisms back to their laboratories to study. They have collected some insects which look like woodlice but they have forgotten to write down where they collected the insects from. To keep the insects alive the scientists need to work out the environmental conditions the insects prefer. To achieve a Level 4 You Must - Say how you will make it a fair test - Identify the Independent variable and the Dependent variable - Identify variables to control (keep the same) - Draw a simple table of results - Write a conclusion based on the data you have collected To achieve a Level 5 You Must - Identify any risks in your investigation and say how you are going to control them - Use the correct scientific words in your conclusion To achieve a Level 6 You Must -Decide on your own how to carry out the investigation - Explain the need to repeat your results -Write conclusions, explaining all of the results you collect - Suggest ways to improve your method

How Science Works What do I need to do to achieve Level 4? Choose all the equipment you will need Say how you will make it a fair test Identify the Independent variable and the Dependent variable Identify variables to control (keep the same) Draw a simple table of results and a bar chart Interpret data which contain positive and negative numbers Write a conclusion based on the data you have collected using scientific knowledge

How Science Works What do I need to do to achieve Level 5? Recognise hazard symbols and use them to identify simple risks in your investigation and say how you are going to control them Be able to design a method which collects data systematically Draw a line graph and write a scientific conclusion from it Use the correct terminology in table headings, graph axes Suggest ways to improve your investigation

How Science Works What do I need to do to achieve Level 6? Choose equipment which is more precise Decide on your own how to carry out the investigation Explain the need to repeat your results Identify a range of risks in each investigation and take action to control them Draw graphs on your own and choose your own scale Write conclusions, explaining all of the results you collect including data which does not fit your pattern using scientific words Be able to calculate mean and make valid conclusions with the manipulated data Suggest ways to improve your method

How Science Works What do I need to do to achieve Level 7? Plan an investigation using information from a range of sources Identify key factors and be able to explain variables which are not easily controlled Choose the most appropriate method which will allow you to collect reliable data Explain why a risk assessment is needed Draw a Line of Best Fit on a graph Identify limitations in primary and secondary data Use symbols and flow diagrams to communicate their understanding Evaluate the data collected to see if it is sufficient for the conclusions made
