Did you know that February 12th is Charles Darwin's
birthday, now known as "Darwin Day"? Charles Darwin was a naturalist, geologist, and biologist. As one of the fathers of evolutionary theory, he is a historical figure worth celebrating in science class.
Darwin Day is a great
opportunity to thank Darwin for his contributions to science and
learn through some great adaptation and natural selection activities.
When the science lessons are over, celebrate Darwin Day with a party!

Who Was Charles Darwin?
Charles Darwin is known for summing up
evidence for the theory of evolution and developing the theory of
natural selection through his travels on the HMS Beagle. His book, On the Origin of Species, shaped modern biology
and evolutionary theory. Some of Darwin's most interesting work, and
what I believe to be the best introduction point for children, was on
the diversity of species, particularly the adaptations of island
finches.

Darwin observed the finches on the Galapagos islands and found that their beaks varied due to the different types of food and environments on each island. Variation is not only seen in bird beaks around the world, but across bird species.

Student Activities: Bird Beak Adaptations
A wonderful hands-on way to engage students in the idea of adaptation is to have them model how these various bird beaks work. There are many activities where this is
explored.
In general, the idea is that you provide your class with
various items that will serve as "beaks", straws,
nutcracker, ladle, chopsticks, etc. The students try to forage for
food items with these different beaks.
You may provide things like
gummy worms in soil, goldfish in water, sunflower seeds to crack,
etc. You can get creative with this, keeping in mind you want to
model something fairly realistic to nature. Many of the items you use
can easily be found around the house.
I love this Bird Beaks Lab from Wild Earth Lab, it provides everything you need to make this a hands-on lesson in the classroom or at home.
You can find a similar activity in the fifth lesson of this Feathered Friends download (free!) from the Cornell Lab.
The Bird Beak Buffet is also a similar activity suggested for ages 11-18.
Throw a Darwin Day Party!
Wouldn't it be fun to throw a Darwin
party after you explore adaptation science? Here are just a few fun
ideas for you!
- Read the book, Who Was Charles Darwin?
- Give out Darwin stickers as party favors!
- Decorate with life size Darwin decals and cardboard cut-outs!
- Have a talented actor come portray Darwin and answer student's questions.
- Combine your Valentine's and Darwin celebrations by handing out some famous scientist valentines including Charles Darwin.
- Visit a local museum that is holding a Darwin Day celebration! Search for events here.
