• 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

• When we exercise our heart rate rises but then drops back down
to its resting rate, when we stop.

sunlight, water, nutrients to
grow.
Carpel

sprout
3. Pollinationoccurs when pollen is
carried from one
flower another flower
5. Seed DispersalSeeds are released from the plant
STAMEN The male part of a plant consisting of
and scattered in different ways such as
• Anthers which store pollen
explosion, animals, wind and water
• 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
EXPLOSIONWATER- Coconuts

and can float
their seams to
scatter their seeds

Freezing Condensing
Evaporation
When a liquid warms up and starts to turn into a
gas.
Condensation
When water vapour cools and turns to liquid.
Melting
When a solid warms up and turns into a liquid.
The water cycle in nature, is an excellent example of the processes
of evaporation and condensation.
Freezing
When a liquid gets cold enough to turn into a
solid.
Water turns

Earth Sun and Moon
Spring equinox –
March 21st
Summer –
June 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
Winter – Dec Hemisphere is pointing away
21st
from the sun. We have
shorter days and longer
nights as the sun’s rays bend
to reach us
Autumn Equinox

DAY & NIGHT
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.
