Science

We aim to inspire a deep-rooted interest in science that Mengham children can continue to develop and nurture long after they leave us. Underpinning this aim is a belief that children are naturally inquisitive about the world around them and throughout the school, the emphasis of science teaching and learning is children finding out about themselves and their environment through first hand experiences.

Wherever possible, we teach new concepts through engaging experiments and other practical activities that allow the children to simultaneously develop their scientific knowledge whilst also building up an awareness of the methods through which scientific knowledge is gained.

Science also provides a ‘motivating context’ for pupils to develop and improve skills in different areas, including literacy and mathematics. 

Children start to decide whether science is ‘for them’ towards the end of primary school. Therefore, as a school we know it essential that children are enthusiastic about science and start to gain an understanding of the value and place of science in their lives.   This will lay the foundation for their future studies and success; enabling them to make well-informed decisions in our increasingly hi-tech world and give them access to a wide range of rewarding careers.

We are very proud to run a science club, which allows children to explore science within a wider context. In addition, the longitudinal studies help to foster a broader understanding of the relevance of what the children study within the classroom.

*opportunity for seed dispersal when seeds are falling from trees.

Light

-light comes from a source

-transparent materials let light through, opaque materials do not let light through *

-Beams of light bounce off some materials (reflection)

-Shiny materials reflect light beams better than non-shiny materials

-There must be light for us to see, without it is dark.

-We need light to see even shiny things.

­Animals: Skeletons & movement

-many animals have skeletons to support their bodies and protect vital organs

– muscles are connected to bones and move when they contract

-moveable joints connect bones

Magnets and their effects

-Magnets exert attractive and repulsive forces on each other

-Magnets exert non-contact forces, which work through some materials

-Magnets exert non-contact forces on some materials

-Magnetic forces are affected by:

  • magnet strength
  • object mass
  • distance from object
  • object material

How plants make their food

-The plant makes its food from water and carbon dioxide, using sunlight as energy, in the green parts of the plant (mainly leaves)

-plants make their own food in their leaves to provide them with energy, grow, repair and reproduce

-Leaves absorb sunlight and carbon dioxide

-Plants have roots to provide support and to draw moisture from the soil, through stems to take water to the rest of the plant

How plants reproduce

-Flowering plants have evolved specific parts to carry out pollination, fertilisation and seed growth

-Seed dispersal increases the chances of seeds germinating and growing into mature plants *

-Seeds and bulbs need the right conditions to germinate. They contain a food store for the first stages of growth (i.e. until the plant is able to produce its own food)

Making electrical circuits work

-A source of electricity (mains or battery) is needed for electrical devices to work.

-Electricity sources push electricity round a circuit.

More batteries will push the electricity round the circuit faster

-A complete circuit is needed for electricity to flow and devices to work.

-Some materials allow electricity to flow easily (conductors). Materials that do not allow electricity to flow easily are called insulators.

-Devices work harder when more electricity goes through them.*Apply

 States of matter

-Materials can be divided into solids, liquids and gases.

-Solids, liquids and gases are described by observable properties.

-Soil is made up of broken down rocks and decaying leaves.

Changing materials

-Materials change state by heating and cooling.

  •   heating causes solids to melt into liquids and liquids to evaporate into gases
  •   cooling causes gases to condense to liquids and liquids to freeze to solids
  •   the temperature at which given substances change state are always the same

-Some changes can be reversed, some cannot.

-When 2 or more substances are mixed and remain present the mixture can be separated. 

Animals: Digestion

-Animals have teeth to help them eat. Different types of teeth do different jobs.

-Different animals are adapted to eat different foods.

-Food is broken down by the teeth and further in the stomach and intestines where nutrients go into the blood. The blood takes nutrients around the body.

-Nutrients produced by plants move to primary consumers then to secondary consumers through food chains.

Variation and Evolution

-Living things can be divided into groups based upon their characteristics.

-Environmental change affects different habitats differently.

-Different organisms are affected by environmental change.

-Different food chains occur in different habitats.

-Human activity significantly affects the environment.

Light

-Light travels in straight lines.

-Light reflects off all surfaces (unless they are black). Non-shiny surfaces scatter the light so we do not see a single beam.

-Animals see objects when light is reflected off that object and enters their eyes.

-Animals see light sources when light travels from the source into their eyes.

Space and Gravity

-Objects like planets, moons and stars spin

-Smaller mass objects like planets orbit large mass objects like stars.

-Stars, planets and moons have so much mass they attract other things, including each other, due to a force called gravity. Gravity works over a distance.

-Objects with larger masses exert bigger gravitational forces.

-Stars produce vast amounts of heat and light. All other objects are lumps of rock, metal or ice and can be seen because they reflect the light of stars. (Apply light learning)

Making new substances

-Heating can sometimes cause materials to change permanently. When this happens, a new substance is made. These changes are not reversible.

-Sometimes mixed substances react to make a new substance. These changes are usually irreversible.

 

Animals: Respiration

-Oxygen in breathed into the lungs where it is absorbed by the blood.

-The hearth pumps blood around the body.

-Muscles need to release the energy from food to do work

  • Oxygen is taken into the blood in the lungs
  • The heart pumps blood through blood vessels to the muscles
  • The muscles take the oxygen and nutrients from the blood

 

Animals: Human Development

-Describe the changes as humans develop to old age.

-Changes experienced in puberty

Animals: Respiration (Y5 only next year)

-Oxygen in breathed into the lungs where it is absorbed by the blood.-The hearth pumps blood around the body.-Muscles need to release the energy from food to do work

  • Oxygen is taken into the blood in the lungs
  • The heart pumps blood through blood vessels to the muscles
  • The muscles take the oxygen and nutrients from the blood

Evolution and natural selection

-Some organisms reproduce sexually (offspring inherit from both parents)-Some organisms reproduce asexually (copy of single parent)-Over time the characteristics that are most suited to the environment become increasingly common-Environmental change can affect how well an organism is suited to its environment-Fossils provide evidence that living things have changed over time.-Different types of organisms have different life cycles-Life cycles have evolved to help organisms survive to adulthood.

Forces that oppose motion

-Air resistance and water resistance are forces against motion caused by objects having to move air and water out of the way.

-Friction is a force against motion caused by 2 surfaces rubbing against each other.

-Some objects require large forces to make them move; gears, pulley and levers can reduce the force needed to make things move.

Light (Y5 only next year)

-Light travels in straight lines.

-Light reflects off all surfaces (unless they are black). Non-shiny surfaces scatter the light so we do not see a single beam.

-Animals see objects when light is reflected off that object and enters their eyes.

-Animals see light sources when light travels from the source into their eyes.

Controlling electrical circuits

-Batteries are a store of energy. This energy pushes electricity round the circuit. When the battery’s energy is gone it stops pushing. Voltage measures the push.

-Current is how much electricity is flowing round a circuit.

-The greater the current flowing through a device, the harder it works.

-When current flows through wires heat is released. The greater the current, the more heat is released.
