Give examples referring to the Sun. Expert Teacher Answer Shadows are formed when light is blocked. They have a similar shape to the object that is blocking the light. Shadows get larger when the object is closer to the light source and smaller when the object is further from the light source. The Sun is the Earth's most important light source. Objects block the light from the Sun and form shadows. These shadows change in size and direction during the course of the day because the Earth turns. When the Sun is directly overhead (mid-day) shadows are their shortest, in the early morning and evening, when the Sun is low on the horizon, shadows are longer. The shadows change direction because the Sun appears to to rise in the East and sets in the West. KS2 Science 4A: Moving and growing Exercise No: 1 Name: 1. Funny Bones No.1: 1.

Expert Teacher Answer Plants and animals live in a certain habitat because it has all the things they need to survive food, warmth and shelter. There are many kinds of habitats because different plants and animals need different kinds of food and shelter. The plants and animals in the habitat make different food chains, most of them starting with a green plant. If anything is removed from the chain, the chain is broken and it is difficult for the habitat to survive. Put together, the plants and animals in a habitat make a food web, each plant and animal depending on the other plants and animals to survive.

Correct Answer colder Incorrect Answer 1 Incorrect Answer 2 Incorrect Answer 3 wetter spicier hotter KS2 Science 4C: Keeping warm Peer Assessment Question and Expert Answer Question What is temperature, how do we measure it and why are thermal conductors and insulators important in our lives? Expert Teacher Answer Temperature is a measure of how hot or cold something is. We can measure temperature accurately using a thermometer. The units we use are degrees Celsius (C). Thermometers are used in many parts of our lives, for example, when we are ill we have our temperature taken (normal body temperature is about 37 degrees C), and when we are baking we need to set the oven to a high temperature (an internal thermometer controls this). Temperature can be controlled by using thermal insulators. Thermal insulators do not allow heat to pass through them easily. For example, a cool box will not allow heat to pass through its lining, and so keeps the food inside cool. Another example is wall insulation, in our houses, which prevents the flow of heat out of the house, thus keeping it warm inside.

Incorrect Answer 2 Incorrect Answer 3 KS2 Science 4D: Solids, liquids and how they can be separated Peer Assessment Question and Expert Answer Question What is the difference between a solid and a liquid? How could you separate a mixture of sand and marbles in water? Expert Teacher Answer A solid has a definite size and shape but a liquid only has a definite size. It takes the shape of a container it is poured into. You could separate the mixture by first using a sieve. When you pour the mixture into the sieve the marbles will be trapped in the sieve but the sand and the water will pass through the holes. Next you could use pour the remaining mixture through the kitchen towel, or filter paper, the sand will be trapped but the water will pass through the tiny holes in the paper. This is called filtering. If you do not have any kitchen towel or filter paper, you could evaporate the water by heating it, and then quickly cool the steam (condense it), to collect the water. The sand would be left in the pot. KS2 Science 4E: Friction Exercise No: 1 Name: Forces No.1: What is a force?

KS2 Science 4F: Circuits and conductors Peer Assessment Question and Expert Answer Question What is the difference between an insulator of electricity and a conductor? How could you use a battery, a bulb and wires to test if a paper clip is a conductor or an insulator? Expert Teacher Answer An insulator does not let electricity pass through it but a conductor does. You could test if a paper clip is a conductor or an insulator by joining up the bulb to the battery using the wires but leaving a gap. You could then use the paper clip to bridge the gap in the circuit. If the bulb lights the circuit is complete and the paper clip is a conductor, if the bulb does not light then the paper clip is an insulator. KS2 Science 5A: Keeping healthy Exercise No: 1 Name: 1.

Expert Teacher Answer A flower has both male and female parts. The carpel is the female part, the stamen is the male part. The male part makes pollen, the female part makes ovules. The pollen has to reach the ovules for the plant to make a seed. The pollen can be carried by the wind or by insects. The wind blows the pollen to another plant. The insects visit the plant to collect nectar. They are attracted by the scent, smell and colour of the plant. The pollen sticks to the insects and is carried to another plant. When the pollen reaches another plant, this plant becomes pollinated. When the pollen and the ovule join together, fertilisation takes place forming a seed. The seed has to be carried away from the plant to be able to make a new plant. This can be done by animals, the wind, explosion and water. When the seed lands in a good place it germinates. This means the plant begins to grow. It cannot grow without enough water, light, heat and minerals. Animals also go through different stages in their life cycle. For example, the stages in the human life cycle are babyhood, childhood, adolescence and adulthood. The babies of different species have different gestation lengths, and spend different amounts of time dependent on their parents. If animals do not reproduce they can become extinct. This can happen when an animal is hunted or its habitat is destroyed. People try to help endangered species by making hunting illegal or by breeding animals in captivity.

KS2 Science 5D: Changing state Peer Assessment Question and Expert Answer Question What do you know about water changing state? Expert Teacher Answer Water can exist in three states. When it is a solid it is called ice, when a liquid it is called water, when a gas it is called water vapour. When liquid water is heated, it evaporates and turns into a gas, water vapour. This is why a puddle seems to 'disappear' on a sunny day. When water vapour is cooled, it condenses and turns into liquid water. Condensation is the reverse of evaporation. When water is heated it boils. The boiling point of water is 100 ? C. When water is cooled, it changes from a liquid to a solid, ice. This is called freezing, and the reverse of this is melting. The water cylce is the name given to the process where water evaporates from seas and lakes, rises up, cools, condenses and then falls to the ground as rain.

Also, how does the Sun affect the things that happen around us - for example day and night? shadows? Expert Teacher Answer The Earth, Sun and moon are spherical with the moon being slightly egg shaped. If the Earth was the size of a pea, then the Sun would be a beach ball and the moon would be a bead. The Earth orbits the Sun and takes 365 1/4 days to orbit (go around). The moon orbits the Earth and this takes approximately 28 days. During this time the appearance of the moon changes and these are called the 'Phases of the moon'. Because the Earth spins on it's axis (one complete turn takes 24 hours) we have day and night with one half of the Earth being in the Sun's light and the other facing away from it. Whilst it appears that the Sun moves across the sky, actually it does not. The Sun appears to move because the Earth is spinning. The Sun rises in the East and sets in the West and is at it's highest point at midday. However, the amount of daylight that we have changes as we go from summer to winter.

KS2 Science 5F: Changing sounds Peer Assessment Question and Expert Answer Question What have you found out about sound through your learning journeys? Expert Teacher Answer Sounds are produced when objects vibrate. Sound travels through all materials- solids, liquids and gases. It cannot travel in space because there is no air. Some materials can be used to block sound and stop it reaching the ear- they can be used to soundproof rooms or make ear protectors. Pitch describes how high or low a sound is. The pitch of notes can be changed by tightening drum skins, lengthening or tightening strings, or changing the amount of air which is vibrating. Echoes are produced when sound bounces off a hard surface such as a wall.

KS2 Science 6A: Interdependence and adaptation Peer Assessment Question and Expert Answer Question A forest is an ecosystem. Describe how the life in a forest is dependant on each other. Suggest what might happen if one part of the ecosystem was removed. Expert Teacher Answer In the forest, insects feed off plants, birds eat insects, larger birds eat smaller birds. Also, small rodents eat the plants and insects, and they, in turn, are eaten by larger mammals and large birds. If you take one of these things away from the environment of the forest, the whole ecosystem is threatened. Without the smaller birds, there would be too many insects, and all the plants and trees would be eaten and destroyed. There would be little food for the larger birds of prey such as owls, and eventually nowhere for them to live. Eventually, there would be no trees or plants left for the insects to eat.

KS2 Science 6C: More about dissolving Peer Assessment Question and Expert Answer Question What have you learned about dissolving? (Use these keywords in your answer - filter, evaporate, solid, liquid.) Expert Teacher Answer When substances dissolve, they form a solution. There are many different types of solutiongases dissolved in liquids, gases in gases, liquids in liquids or solids dissolved in liquids. You can separate solids which have not dissolved from liquids by filtering, but dissolved solids have to be separated by evaporating the liquid. The rate at which a solid dissolves can be affected by the size of the particles, temperature of the water, or the amount of stirring. When a solid is added to a liquid, eventually no more will dissolve because the solution is saturated. KS2 Science 6D: Reversible and irreversible changes (short ) Exercise No: 1 Name: 1.

KS2 Science 6D: Reversible and irreversible changes (short ) Peer Assessment Question and Expert Answer Question You have been asked to write definitions for a scientific dictionary for the terms 'reversible change' and 'irreversible change'. What will you write? Expert Teacher Answer A reversible change is when you have mixed materials and you can easily get the materials back by sieving, filtering, decanting and by evaporation and condensation. When you mixed the materials you did not make a new substance. An irreversible change is when you have mixed materials and a reaction has happened that produces new materials. You cannot get the materials that you mixed back. When you burn materials this causes an irreversible change. Heat can also cause an irreversible change, for example when you fry an egg.

KS2 Science 6E: Forces in action Peer Assessment Question and Expert Answer Question Forces are found all around us. Describe the forces you have studied and include an example of where they can be observed and what units are used to measure them. Expert Teacher Answer There are many forces around us and they are all measured using the unit Newtons. Gravity is the force which attracts objects to the centre of the earth. It can be seen acting when a ball is dropped. Air resistance or drag is the force produced by air trying to stop objects moving. It can be found acting on a parachute where it slows down the person before they reach the ground. Upthrust is the force which helps keep boats afloat. It was discovered by Archimedes. It is a force which acts in the opposite direction to gravity and is found in liquids. Friction is a force which tries to stop objects moving. It can be useful especially on roads to stop cars from skidding off when they reach a corner. Magnetism is a force which attracts iron, nickel, cobalt and steel. It is found in magnets and some rocks. Weight is a force created by gravity. It is the force by which an object is pulled towards the ground. The more mass an object has the greater its weight.

KS2 Science 6G: Changing circuits (short ) Peer Assessment Question and Expert Answer Question How can you increase or decrease the brightness of a bulb in a circuit? Expert Teacher Answer I could change the power supply - adding more batteries would make the bulb brighter, but I need to make sure I don't add too many batteries or the bulb would explode. I could add more bulbs. This would make the bulbs dimmer as the power would have to be shared between the bulbs. I could also add another device like a motor or a buzzer. This would have the same effect. I could shorten or lengthen the wire. A shorter wire would make the bulb brighter, as it has less resistance. A longer wire would make the bulb dimmer. I could use thicker or thinner wire. A thicker wire would make the bulb brighter, a thinner wire would make the bulb dimmer.
