For my teeth I need to make sure that I clean them properly at least twice a day, visit the dentist

healthy diet, I need to make sure I eat balanced meals, eating different kinds of food in the right
quantities. I need 6 - 11 servings of carbohydrates like bread cereal, rice and pasta each day. I
also need 5 servings of fruit or vegetables, 2 or 3 of meat or eggs or nuts and 2 or 3 of dairy
products like milk and cheese. I should be careful about how much fats, oils and sweets I have,

Question
Describe the properties of different rocks that you have studied and give examples of how
these properties can be useful to people.
Expert
Teacher
Answer
Some rocks such as chalk and sandstone are permeable and let water pass through them. Other
rocks like slate and marble are impermeable and do not let water pass through them. Slate also
has the property that it can be split into thin sheets and this makes it a great material for using on
roofs. Rocks such as granite, sandstone and limestone are all used for building. Granite is very
hard and solid, but sandstone can have problems with weathering and limestone with acid rain.
Usually buildings are made with rocks that can be found locally.

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.

Answer
You have a skeleton inside your body. A skeleton is made of bone which grows as you grow. The
skeleton supports the body and gives it shape. It protects the organs. There are joints where two
or more bones meet. Muscles are joined to the skeleton. They work in pairs. One contracts while
the other relaxes to make your bones move. Ligaments join bone to bone and tendons join
muscle to bone. Movement of your body depends on both your skeleton and your muscles.
Exercise will make your muscles stronger.

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.

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.

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.

friction.
Expert
Teacher
Answer
Friction is a force that slows things down. It can be measured in Newtons, using a forcemeter.
There is high friction between two rough, dry surfaces. There is low friction between two smooth,
wet surfaces. Advantages: 1) The treads under our trainers prevent us from slipping. 2) The brake
pads on a car press together to stop the car moving. Disadvantages: 1) Air resistance pushes
against an aeroplane and so reduces its speed. 2) Friction can also cause engines to wear out as
the parts move against one another.

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.

Question
What do you know about plant and animal reproduction?
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.

Why are gases important to us?
Expert
Teacher
Answer
The air which surrounds us, which is made up of different gases, keeps the Earth's temperature
stable, and is needed by all living things to survive. Oxygen in the air, is taken in by our lungs
when we breathe. Moving air helps us to dry washing, and keeps kites and parachutes in the air.
Other gases are useful to us, such as hydrogen used in welding, carbon dioxide in fizzy drinks
and neon in lasers and neon signs. Without the gases formed when liquids evaporate, we would
not be able to smell.

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.

Question
What have we learnt about the Earth, Sun and moon? Try to write some interesting facts
about each one. 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.

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.

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.

Some micro-organisms are helpful, some are harmful. They can be found everywhere on earth
and all over the human body. They are very small and cannot be seen. The harmful microbes
grow and reproduce on food and this can cause food poisoning. They also cause diseases to be
passed on. Micro-organisms are helpful because they cause materials to decay so that rubbish
doesn't pile up. They are also useful in making food like bread and yogurt.

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.

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.

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.

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.
