Sunflower seed growing lesson
In this lesson you will get to see what happens under the soil when a sunflower seed germinates. You’ll learn the parts of a sunflower plant and find extra resources for sunflower-themed learning, including free printables!
You will need:
:: sunflower seeds
:: magnifying glass
:: a glass or clear plastic pots
:: cotton wool, tissue or soil
Sunflower seed observation
Let’s begin by using our senses to investigate our seeds.
Take a good, close look at them – you can use your sunflower journal to draw your seeds and make some notes.
What shape is your seed?
What colour is it?
Does it have any markings on it?
Does it smell?
What does it feel like? Is it smooth or textured?
Can you peel off the outer casing of your seed and have a look inside?
Can you think of any seeds that you like to eat?
How are seeds like animal embryos? What are the differences between the two?
How to plant your seeds
To start your experiment, decide what you want to use as your ‘soil’ and use it to fill a glass or clear plastic pot.
For the best view, you can use cotton wool, scrunched up tissue or kitchen paper. This won’t give your little plant sufficient nutrients to develop into a strong plant, but it is a great way to get a good view of a few seeds as they germinate.
If you want to plant your seedlings and grow them on, it’s best to use soil or compost.
Whatever you decide to use, dampen it down with a little water, and pop your seeds inside. Place the seeds at the edge of the pot so you can get a good view of them as they began to grow.
Germination is the process by which a plant grows from a seed.
A seedling is a young plant grown from a seed.
Charting your seeds progress
Decide what you would like to measure. Here are some ideas:
:: how long does it take for something to start growing?
:: how long is it before there is a leaf?
:: how long before there is a flower?
:: how long before there is something to eat?
You could ask everyone to guess the answers to each question and record their predictions in your Sunflower Journal.
Graphing your results
You can record your seeds progress in a number of ways, depending on how detailed you would like to be.
:: You can keep a photo or sketch journal, making a picture of each new development and a note of the day it happens.
:: You can draw out a simple number line and count along the days, making note of germination, first leaf etc. as you go along. This is good for younger children who simply want to count.
:: Older children can draw a tally chart, or a bar graph to compare a several seeds alongside each other. You can also make a graph with a x-axis showing the number of days and a y-axis showing the height of your plant.
:: Make a sunflower height chart to track who’s taller: you or your plant?
The parts of a sunflower plant
When the seeds begin to grow you can take photos and draw pictures of what you see and there’s lots of opportunity for discussion too.
You can follow germination, when the seed first starts to grow. Then the appearance of roots and the stem. The first leaves are called cotyledon, with the true leaves coming a little later.
I wonder what all the parts of the plant are called?
I wonder why a seed need roots and leaves?
I wonder how the seed knows how put the root at the bottom and the leaf at the top?
I wonder what happens if you turn a seed upside down when the root has just begun to grow?
I wonder what happens when you turn the plant around so it’s facing the window from a different side?
And watch how these sunflower seeds, from Temponaut Timelapse, emerge from the soil and dance.
Join the NurtureStore Sunflower Club :: free resources for your children!
Let’s connect our children to nature all spring and summer long with an engaging curriculum all based around sunflowers.
My Sunflower Club programme is free to join and will give you six complete units of lesson plans, activity ideas and printables that you can use with your children to:
:: grow sunflowers together and watch the natural cycle of the year from seed, to plant, to flower, to seed
:: see math and science in action with hands-on practical activities and observations
:: create sunflower art inspired by your own plants and works by Vincent Van Gogh and Georgia O’Keefe
:: learn about bees and the vital role they play on our planet
:: wonder at the patterns that occur in nature, learning about symmetry and Fibonacci
:: write your own sunflower poems and make a unique Sunflower Journal
:: harvest your own seeds at the end of the year, using them for recipes and to create your own sustainable garden, year after year
:: NurtureStore Supporters get extra bonus printables all through the spring and summer!
Gardening :: Environmentalism :: Science :: Math :: Art :: Fun!
