(1 mark) (1 mark)1Drinking water(a)People who walk in the mountains can travel a long way from towns. They might have to get their drinking water from a stream. The water must be made safe before they drink it. Animals can be separated from the water using the equipment shown below. What is the equipment in the picture below called? ...................................................... (b)It is important to put the animals back where they were found. Write true or falsenext to each statement to show why it is important for the animals to be put back in the stream. ....................... .......................because the animals are adapted to live in the stream so the animals do not get eaten by predatorsTrueor false?   6$ bucket plant materials animals bits of mudstream water

(1 mark) (1 mark)  6$ (c)There are still bits of mud in the water. The mud can be separated from the water by filtering. Explain how the filter paper separates the mud and water. ................................................................................................................. ................................................................................................................. (d)It is still not a good idea to drink the water because there are micro-organisms in it. What is likely to happen to people who drink stream water with micro-organisms in it? ................................................................................................................. (e)Boiling the water helps to make it safe to drink. TickONEbox to show the best way for walkers to boil the water. (f)TickONEbox to show the temperature at which water boils.Hold it over a torch.Put the water in an insulated flask.Hang it over a fire in a pot. Leave it in a sunny place.0°C1000°C 100°C 10°Cjug filter paper funnel(1 mark) (1 mark)

(1 mark) (1 mark)2Circuit(a)Abida makes a circuit with a bulb, cell and wire. Complete the diagram of Abida’s circuit below by drawing the symbol for a cell and connecting the cell in the circuit. (b)Name the piece of equipment that Abida could add to her circuit so she can turn the bulb on and off. ..................................................... (c)Abida wants to measure the brightness of the bulb in her circuit. She puts the bulb and a light sensor under a box. The light sensormeasures the brightness of the bulb. Tick ONEbox to show why Abida puts boththe bulb and light sensor inside the box.so the bulb is insulatedso the bulb lights up more brightlyso she does not measure light from other sources so the light from the bulb cannot be seen(1 mark)   6$

   6$ (2 marks)(d)Abida uses the sensor to measure the brightness of the bulb in the circuit below. She wants to find out if she can change the brightness of the bulb in her circuit. Each time she adds one object between the clips, the bulb lights up. Abida measures the brightness of the bulb for each object. Then she takes the object out again. How will the brightness of the bulb change when Abida correctly adds each object to her circuit? Tick ONEbox in each row of the table.Object usedwill be dimmer.will be brighter. will not change.The bulb…copper wire a motor another cell another bulb

(1 mark) (1 mark)3Heating water(a)Jenna has three saucepans of water. Jenna wants to find out how long it will take to heat each saucepan of water to 50°C.Look at the diagram. What variable is Jenna changing in her investigation? ................................................................................................................. (b)Jenna times how long it takes to heat each saucepan of water to 50°C. Jenna’s mum helps her to do this safely. Name a piece of equipment Jenna could use to measure the temperature of the water. ..................................................... (c)Each saucepan has a wooden handle. How does the wooden handle make using the saucepan safer? ................................................................................................................. .................................................................................................................ABC(1 mark)   6$

(1 mark)   6$ (1 mark)(d)The graph below shows how the water temperature changed in each saucepan. When Jenna looked at the graph she realised her test was notfair. Why was Jenna’s test notfair? Use the graph to help you. ................................................................................................................. ................................................................................................................. (e)How much time did it take the water in saucepans Aand Bto reach 50°C? Use the graph to help you complete the table.Saucepan A B CTime to reach 50°C (seconds)66

(1 mark) (1 mark)4River wildlife(a)Some children visit a river and see a duck, a swan and a frog. The children use the features of the animals to sort the duck and swan into one group and the frog into another. (i)Name a feature of the duck and the swan that puts them in the samegroup withoutthe frog. ...................................................................................................... (ii)Describe a feature the children could use to put the duck and the swan into differentgroups. ...................................................................................................... (b)Duckscan be sorted into different groups. TickONEbox to show why it is a good idea to sort the ducks into groups.to work out what a baby duck will look like when it growsto help rescue ducks from polluted riversto help identify different ducks because there are a lot of plants ducks like to eat3KRWRJUDSKV UHSURGXFHG E\NLQG SHUPLVVLRQ RI-0RRUHV(1 mark)  6$ [These are not to scale]DuckSwanFrog
