KS2 - Year 3 - Plants

Room for growthFree! 

Outstanding Science Year 3 - Plants | OS3A003

Children grow 1, 4, 9 and 16 onion sets in 4 different pots. They make observational drawings and measure the height of the plants over 4 weeks. They use their measurements to complete a line graph showing the growth of all plants.

  • 3a2: explore the requirements of plants for life and growth (air, light, water, nutrients from soil, and room to grow) and how they vary from plant to plant
I can investigate how competition for resources affects plant growth.

Plant anatomy 

Outstanding Science Year 3 - Plants | OS3A001

Children look at 9 images of food plants. They identify the different parts, including roots, tuber, stem, bulb, trunk, branch, leaf, flower, and fruit. They discuss which part of the plant we normally eat.

  • 3a1: identify and describe the functions of different parts of flowering plants: roots, stem/trunk, leaves and flowers
  • lks2w8: identifying differences, similarities or changes related to simple scientific ideas and processes
I can identify the main parts of different flowering plants.

Plant Functions 

Outstanding Science Year 3 - Plants | OS3A002

Children label a diagram of a flowering plant. They explain the function of the flower, stem, leaves and roots. Children can cut and paste descriptions or write their own.

  • 3a1: identify and describe the functions of different parts of flowering plants: roots, stem/trunk, leaves and flowers
I can explain the functions of the different parts of a flowering plant.

The needs of different plants 

Outstanding Science Year 3 - Plants | OS3A004

Over the course of 4 weeks, children compare the growth of a tomato plant, a cactus plant, and cress when grown in sand rather than compost. They identify the variable, make a series of observational drawings and explain what happened.

  • 3a2: explore the requirements of plants for life and growth (air, light, water, nutrients from soil, and room to grow) and how they vary from plant to plant
I can investigate the needs of different plants.

Water transport in plants 

Outstanding Science Year 3 - Plants | OS3A005

Children predict and measure how long it takes for coloured liquid takes to rise up the stem of a carnation flower and colour its petals.They make a drawing of the flower at the start and end of the investigation and predict what would happen if the flower had a shorter stem.

  • 3a3: investigate the way in which water is transported within plants
I can investigate how water is transported in plants.

Life cycle of a flowering plant 

Outstanding Science Year 3 - Plants | OS3A006

Children read about the 4 stages in the life cycle of a flowering plant - germination, growth, flowering, and fertilisation/seed production. They create a life cycle diagram, cutting and pasting descriptions and pictures or writing and drawing their own.

  • 3a4: explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal.
I can describe the life cycle of a flowering plant.

Pollination methods 

Outstanding Science Year 3 - Plants | OS3A007

Children learn how pollination is vital to flowering plant reproduction. They read about insect pollination and create their own process description by either cutting and pasting descriptions or writing in their own words.

  • 3a4: explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal.
I can explain different methods of pollination in flowering plants.

Seed dispersal methods 

Outstanding Science Year 3 - Plants | OS3A008

Children learn about different seed disperal methods eveolved by plants including dispersal by gravity, by wind, by water, and by animals. They examine 6 different images of fruits and seeds and try to explain how they might be dispersed.

  • 3a4: explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal.
I can explain different methods of seed dispersal in flowering plants.
