5A KEEPING HEALTHY – Part 1

Remember to stay healthy we need a varied and balanced diet

Fats provide insulation and energy. Only eat in small amounts.

Proteins help muscles to grow, and repair damaged cells and tissue. Found in meat, fish, beansVitamins and

minerals found in fruit and veg are essential for healthy bodily functions

Dairy Products such as milk, cheese, yoghurt, are a good source of protein and calcium, but also contain fat

Carbohydrates are essential for energy. Sugars in fruit and starch in bread, pasta, rice, potatoes

Lungs

Oxygen rich blood flows from the lungs to the heart

Oxygen rich blood is pumped from the heart to the body

Oxygen poor blood is pumped to the lungs from the heart

Body

Oxygen poor blood flows back from the body to the heart

• Beckham’s heart rate at the start of the match is 60 BPM.• His heart rate rises because he is active and his heart is pumping blood to his muscles • Beckham’s heart rate drops after 45 minutes because he rests at half time• When we exercise our heart rate rises but then drops back down to its resting rate, when we stop.

5B LIFECYCLESPARTS OF A FLOWER

1.Germination-the seed starts to sprout

3. Pollination- occurs when pollen is carried from one flower another flower

5. Seed Dispersal- Seeds are released from the plant

and scattered in different ways such as explosion, animals, wind and water

2. Growth- plants need sunlight, water, nutrients to grow.

STAMEN The male part of a plant consisting of • Anthers which store pollen• Filaments which are the stalks holding up the anthers CARPEL The female part of the plant made up of the • Stigma where the pollen arrives • Style which is a tube that joins the stigma to the ovary • Ovary where the eggs (ovules) are stored.PETAL: a brightly coloured part of the flower, which attracts insects and helps a plant pollinate.SEPAL: The protective leaves around the flower when it is a bud

EXPLOSION- seedpods split suddenly along their seams to scatter their seeds

WATER- Coconuts have hollow centers and can float

WIND- Seeds covered in feathery materials, act like parachutes when caught in the wind.

When gases escape from containers they flow in every direction

What happens when we pour water into beakers where there are gaps or spaces between the solid objects?

Bubbles of air

We smell things when gases enter our noseWe smell liquids when some of the liquid evaporates

Melting EvaporationSolid Liquid Gas

Freezing Condensing

The water cycle in nature, is an excellent example of the processes of evaporation and condensation.

Lava is molten rock, but it has to be very hot to melt rock!

Chocolate goes soft and gooey if you heat it. Cool it down and it goes hard again

EvaporationWhen a liquid warms up and starts to turn into

a gas.

CondensationWhen water vapour cools and turns to liquid.

MeltingWhen a solid warms up and turns into a liquid.

FreezingWhen a liquid gets cold enough to turn into a

solid.

Changing State

Water turns into snow or ice when it gets very cold. When it warms up it turns back to water

Washing drying on the line is a good example of evaporation

Earth Sun and Moon5E

Summer – June 21st

Winter – Dec 21st

Autumn Equinox – Sept 21st

Spring equinox – March 21st The Earth is tilted at 23 . ;

Because of this, in our Summer the Northern Hemisphere is pointing towards the sun . This gives us long days and short nights, with warm temperatures as the Sun’s rays shine direct on us.In winter the Northern Hemisphere is pointing away from the sun. We have shorter days and longer nights as the sun’s rays bend to reach us

Year 5 Revision booklet 9

Earth Sun and Moon5E

The earth spins or rotates on its own axis. It takes 24 hours for the Earth to spin once on its axis.

As the Earth spins, some parts are facing towards the sun and some parts face away from the sun. This causes day and night.

The earth spins from west to east. This means the sun always rises in the east and sets in the west. The sun moves across the sky in an arc and is at its highest point at midday.

During the winter, the sun is much lower in the sky and the number of daylight hours is much less.

DAY & NIGHT

Changing Sounds

• Sounds are made by vibrations,• Sounds travel through any substance which

has particles and which can vibrate eg air, walls, water etc

• Musical instruments vibrate strings, skins, wooden blocks, columns of air etc.

• Sounds are muffled by thick materials.
