What do we learn about plants in Y3?

A plant is a living organism. In primary school children learn about a wide variety of different types of plants including flowers, trees and vegetables.

 

What are plants?

Plants are living things that grow from the soil and turn light from the Sun into food. Plants can be big or small, from giant trees to tiny patches of moss.

Plants use a process called photosynthesis to turn sunlight into food in their leaves. They can then use this food to grow. To help them do this, they also need water and nutrients that they take from the soil with their roots, and carbon dioxide that they absorb from the air.

 

Did you know?

  • Plants need light to grow. If you put one plant on a windowsill in the sunlight, and one plant in a dark cupboard, the plant in the sunlight will be green and healthy and the plant in the cupboard will start to die.
  • Brightly coloured flowers look very pretty to us, but that’s not why plants grow them. The bright colours and patterns on the flower petals are very attractive to insects. The insects come to the flowers to drink nectar, and they carry pollen from one plant to the next.
  • When a plant has been pollinated, it creates a seed (or lots of seeds). These seeds will make the next generation of plants. A seed contains the start of a new plant and some food to help it grow until it’s big enough to get food on its own.
  • When a seed sprouts and starts to grow, it is called ‘germination’. You can see germination in action by taking some seeds and putting them on a damp piece of kitchen towel in a dark cupboard. This makes the seed think it’s in some moist soil, and it will start to grow after a few days.
  • Lots of types of animal only eat plants. They are called ‘herbivores’.
  • The huge variety of fruit and vegetables that you find in the supermarket doesn’t just turn up there by chance. They have to be carefully grown and looked after. People who grow plants for people to eat are called farmers.

We will:

Watch and observe:
Children will be given opportunities to watch and observe plants and vegetables grow. They will plant their own seeds either in pots or the school grounds. Children will observe trees and plants growing in their local environment if possible this might be during forest school lessons, in the school garden/ vegetable patch or walks and trips to the park and woodlands depending on the school facilities. Children may use magnifying glasses to examine the parts of flowers closely.

Diagrams, photographs and drawing:
Children will draw and label plants including trees and plants. Children may keep charts, graphs and records of plant growth.

Experiments:
Children will plan and carry out investigations and experiments for example they might plan a fair test to determine if a plant needs water to grow.

Video clips/books/images:
Children may watch video clips to teach them about plants and research using the internet and book for example they might research pollination.

Photographs, charts, classification grids:
Children will use pictures and classification charts to identify different flowers, trees and plants.

After May half term: ROCKS

What are igneous, sedimentary and metamorphic rocks?

Rocks are made up of different minerals and form the Earth’s crust (outer layer). Different combinations of minerals form rocks; minerals are made of elements.

There are 3 different types of rocks; igneous, sedimentary and metamorphic.

Igneous rock is formed when magma or lava from volcanoes cools. Examples include basalt and granite. Most igneous rock is very hard. Some of the most spectacular rock formations on our planet are made of igneous rock; in Britain we see granite shapes called tors in south-western locations like Bodmin Moor, Dartmoor and Land's End.

Sedimentary rocks are formed over millions of years when sediments (tiny pieces of rocks and animal skeletons) are pressed together at the bottom of seas and rivers. Examples include sandstone, coal and chalk. Some sedimentary rocks contain fossils (bones or shells of living things that were buried long ago and have turned to stone).

Metamorphic rocks are formed when other rocks are changed due to heat or pressure. Examples include slate and marble. Metamorphic rocks are very hard but can be damaged by acids like acid rain (on buildings) or even lemon juice (on worktops!).

Fossils are created when plants or animals are trapped within rocks. 

Soils are made from rocks and organic matter.

We will be:

  • Comparing Children might observe and compare rock or soil samples in the classroom and look at rocks used in local buildings and gravestones. They may use magnifying glasses or a microscope to look closely at rocks to find crystals, grains and fossils. 
  • Classifying Children may be asked to classify rocks (or soils), usually working in a small group. They will be provided with a sample of rocks and a classification key to help them work out which rock is which.
  • Investigations They may investigate (plan and carry out a fair test) what happens to rocks when they are rubbed together or if they absorb water.
  • Purpose and use They will discuss and consider the use of different rocks; for example, slate is useful for roof tiles and chalk for drawing with. Children may be given a matching activity where they are asked to suggest the best rock for a specific purpose.
