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. INSECT POLLINATED FLOWERS WIND POLLINATED FLOWERS large, brightly coloured petals, often sweetly scented, usually contain nectar - to attract insects small petals, often brown or dull green no need to attract insects pollen produced in great quantities pollen is very light and smooth - so it can be blown in the wind 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. Carpel

Only vibrate Particles slightly further apart Roll over each other Particles spread out Bounce off each other Properties of Solids, Liquids and Gases Item What gas does it use? Gas Cooker Fizzy Drinks Balloons Oxygen tank Natural Gas Carbon Dioxide Helium Oxygen 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 marblesspongesoil We smell things when gases enter our nose We smell liquids when some of the liquid evaporates Perfume

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 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. Freezing When 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
