KS3 ScienceYear 8Science SkillsName:Class:Teacher:The focus of this topic is to prepare you foryear 8 and GCSE science by practising thepractical, science and maths skills required tosucceed.In this topic you will learn about: Weight and gravity Animal adaptations Heat flow Combustion and the fire triangle DiffusionThis will prepare you for: Year 8 science GCSE Combined science GCSE Triple scienceKey epeatableAccuratePrecise

Task 1: Huddling planIn and On: What is the mean and range of the following sets of numbers?0.13, 0.12, 0.11, 0.15, 0.14, 0.1429, 36, 40, 38, 41Learning outcomes: Recap the methods of heat transfer Identify variables for an investigation Plan a practical with suitable controlsWhy is happening in this image? Why?The scientific method:1.2.3.4.5.6.Ask a questionE.g. Why is this tin heavy?Do some background researchFind out what types of objects are put in tins and what the tinis made from.Construct a HypothesisThe tin contains golden syrup as that is what is made by thiscompany.Test your hypothesis with an experimentShake the tinAnalyse your data and draw a conclusionThe sound made when I shook it doesn’t match what I wouldexpect from golden syrup.Report your findings.My hypothesis was incorrect.

What are the three methods of heat transfer? Web link shorturl.at/nvN02What are the main features of each of these methods of heat transfer?MethodDescription of how theheat is transferredWhat can it movethrough?Aim of practical:In this practical you will use test tubes with hot water to model heat transferin penguins. One test tube will be on its own whereas the other will besurrounded by others which have hot water in too.What will be the independent variable? (What will you change?)What will be the dependent variable? (What will you measure?)What are the control variables?(What will you keep the same to make it a fair test?)

Describe how you will carry out the experiment.(Name the key equipment you will use and talk about how you will measureyour results)Equipment list:Draw a diagram of the practical:
