We've done this project every year since we started homeschooling 11 years ago! The theme is the same but we do new and different activities every year. Last year we focused on hibernation and animal migration. This year I thought we'd mix and match with some outside activities and some science activities.
The kiddies started their week with a farm shop. Each fruit or vegetable came with a price tag per 100 grams and the kiddies had to work out the prices depending on weight. Fun + maths = learning.
Peeling pears to make...
...stewed pears.
We learnt how chlorophyll is the dominant pigment in leaves. There are other pigments in leaves but they can't be seen while the chlorophyll dominates during the summer months.
As the sun hours lessen in the Autumn the chlorophyll stops dominating and the other colours come through. The pigment carotenoid is yellow and orange.
Red pigment is called anthocyanin and is not there all year round. It is produced in the autumn if there is sufficient sunlight. That is why mild autumns produce particularly spectacular colours.
I asked the children to create their own way of explaining this science behind leaf colour.
The Boy made a green leaf canopy which opened to show yellow and orange leaves and their pigment names. He glued these in to show their permanent, if not visible, place in a leaf. The red leaves he blue-tac-ed in to show that not every autumn has enough sunlight for anthocyanin sugar production.
Monkey Girl made a lovely sliding picture to demonstrate the pigment names. Brown pigment is called tannin. This is particularly visible in oak tress.
Panda girl made a poster with pigment names and an explanation of the changing seasons.
And then we made a bug hotel.
The boy placed pebbles on the top in an 'L' shape for 'landing' to show the dragonflies where to land. Cute!
