IntroductionWhat is this Workbook for?This Workbook will help you to develop your knowledge and skills in science.As you work carefully through it, you should find that you get gradually better andbetter at doing things such as:t using your knowledge to work out the answers to questions, rather than justremembering the answerst planning experiments, recording results, drawing graphs and makingconclusions.How is the Workbook organised?Laboratory apparatusThe first few pages in the Workbook show you diagrams of the different kinds oflaboratory apparatus you will use when you do practical work.You can write in their names and what you used them for.Useful wordsThere are some words that you will use quite often during your science course.Their meanings are explained on pages 10 and 11.ExercisesThe exercises will help you to develop the skills you need to do well in science.The exercises are not quite the same as the questions that you will meet on theProgression Tests or your Checkpoint examination.This is because the exercises are to help you to get better at doing particularthings, rather than testing how well you can do them.The exercises are arranged in the same order as the topics in your Coursebook.Each exercise has the same number as a topic in the Coursebook.There is not always an exercise for each topic. For example, there is an exercise foreach of topics 1.1, 1.2, 1.3 and 1.5. There is no exercise for topics 1.4 or 1.6.Introduction3

Laboratory apparatusYou will use lots of different pieces of apparatus when you do practical work.Each time you use a new piece of apparatus, find its picture here and write in itscorrect name. Then describe what you used the apparatus for.

Useful wordsabsorb soak upPlant leaves absorb energy from sunlight.Porous rocks can absorb water.conclusion a simple statement summarising what theresults of an experiment tell youJovanka did an experiment to investigate whether metals and nonmetals conduct electricity.Her conclusion was that metals conduct electricity, but most nonmetals do not conduct electricity.describe say what happens, or what you can see, orwhat your results areShane described what happened when he added some acid tosome alkali. He said that the indicator changed colour from the UIcolour at pH 10 to the UI colour at pH 7.explain say why something happensShane explained what happened when he added some acid tosome alkali. He said that the pH changed from pH 10 to pH 7,because the acid neutralised the alkali.fair test an experiment where all the variables arekept the same, except the one whose effect we are investigatingSonali is doing an experiment to investigate how temperatureaffects the rate at which a fungus grows on bread.She makes it a fair test by making sure that the only variable thatchanges is the temperature.functionjob, use or purposeOne function of a plant’s roots is to absorb water.The function of a forcemeter is to measure a force.10Useful words
Useful wordsparticlea very small pieceSometimes, we use the word ‘particle’ to mean the verysmallest piece of something that can exist – so small that we cannotsee it even with a microscope.In a solid, the particles are tightly packed in a regulararrangement, vibrating on the spot.Sometimes, we use the word ‘particle’ to mean a bigger piece –something that we can easily see with our eyes.In a clay soil, the soil particles are small with only tiny air spacesbetween them.property the way that something behavesOne property of metals is that they can conduct electricity.A property of liquids is that they can flow.unita standard quantity that we use for measuring somethingThe unit for measuring length is the metre.The unit for measuring mass is the kilogram.variable something that can change, especially in an experimentSonali is doing an experiment to investigate how temperatureaffects the rate at which a fungi grows on bread.The variable she changes is the temperature.The variable she measures is the growth of the fungus.Three of the variables she keeps the same are the kind of bread,the size of the bread and the amount of water he adds tothe bread.Useful words11
Unit 1Exercise 1.1Plants and humans as organismsComparing leavesThis exercise will help you to practise observing carefully. You will also thinkabout how to record your observations in a table.1 Find two leaves from two different plants. Decide which one will be Leaf Aand which will be Leaf B.2 Look very carefully at the two leaves. Make a list of three features that are thesame in both leaves.first feature.second feature.third feature.121 Plants and humans as organisms
Unit 1Plants and humans as organisms3 Now look for differences between the leaves. Write descriptions of the differencesin the table. You can add more rows to the table if you like.FeatureLeaf ALeaf Blengthshapecoloursurfaceedgepattern of veins1 Plants and humans as organisms13
Unit 1Exercise 1.2Plants and humans as organismsHuman organ systemsThis exercise will help you to remember what you have learnt about four organsystems in the human body.For each of the functions listed, write the name of the organ system that has thisfunction. Choose from:respiratory systemcirculatory systemnervous systemdigestive systemThen list at least two organs that are part of each organ system.FunctionOrgan systemtransporting substancesround the bodybreaking down food andabsorbing it into the bloodtaking oxygen into thebody and getting rid ofcarbon dioxidehelping different parts ofthe body to communicate141 Plants and humans as organismsSome organs in the system
Unit 1Exercise 1.3Plants and humans as organismsBreaking bonesThis exercise will help you to practise reading information from a bar chart.Most of our bones are very strong. They do not break easily. But very strongforces on a bone can make it snap.The bar chart below shows information about the bones broken in a countryin Europe in one year. It shows which bones in the arms and shoulders werebroken most often in people under 18 years of age.15 000radius or ulnagirlscarpalsboys10 000number of breaksper yearhumerus50000Use the bar chart to answer these questions.claviclescapulabone1 Which bones were broken most often?.2 For boys, how many times was a humerus broken during the year?.3 How many more times did a boy break his radius or ulna than his humerus?Show how you worked out your answer.4 How many times did girls break a bone in a part of the arm below the elbow?Show how you worked out your answer.1 Plants and humans as organisms15
Unit 1Exercise 1.5Plants and humans as organismsAntagonistic muscles in the legIn this exercise, you will be using what you have learnt about the muscles in thearm to predict how the muscles in the leg work. It’s important not to get worriedwhen you see something new that you think you have not learned about. Justthink about what you have learnt, and use it to help you in thisunfamiliar situation.ABDCThis diagram shows the muscles in a person’s leg.1 On the diagram, label these bones:the femurthe pelvisthe tibia2 What kind of joint is the knee joint?.3 On the diagram, label a ball-and-socket joint.4 Look carefully at the diagram. What will happen at the knee joint when muscleA contracts?.5 What will happen at the knee joint when muscle B contracts?.
