Daffodil Dissection

Daffodil Dissection

You will need

  • A daffodil
  • Scissors
  • Tweezers (optional)
  • Magnifying glass (optional)

How to do it

  1. Take a daffodil and carefully begin the dissection. Start with the outer parts of the daffodil: sepal, petals etc.
  2. Use a pair of scissors to cut the corona. You may also want to use tweezers to assist with the dissection.
  3. Continue to dissect the remaining parts of the daffodil, laying them out on a flat surface.
  4. Use a magnifying glass to take a closer look at each part of the daffodil.

What are we learning

A flower dissection is a great way to get children to really engage with the parts of a flower. Flowers like daffodils and lilies work particularly well for this activity. Children will enjoy discovering and labelling all the different parts of the flower and researching their purposes.

Investigate

Go on a nature walk and look at other types of flowers. What flower parts do they have in common? What are the differences?

You will need

  • A flower
  • A pestle and mortar
  • A jug of water and a teaspoon
  • Vinegar
  • Bicarbonate of Soda
  • A paint/baking tray

How to do it

  1. Drop two petals into a pestle and mortar.
  2. Add two teaspoons of water and mix until the water changes colour.
  3. Use a syringe to collect up the mixture. Then add it into three different tray wells.
  4. Add a teaspoon full of vinegar to the first tray well and mix. This is your acid indicator.
  5. Add a teaspoon of bicarbonate of soda mixed with water to the second tray well and mix. This is your base indicator.
  6. Compare the colours in each tray well. What is different about them? Why do you think this is?

What are we learning

A rose is an example of an acid-base indicator. Other flowers that you could use include tulips and pansies. When we add an acid it turns the petal mixture an orange or pink colour. When we add the base it turns the petal mixture a blue or purple colour.

Investigate

Now try this with a range of other flowers. Which ones are acid-base indicators? You could also try this activity with fruit and vegetables.
