How is the flight of these animals the same?
How is their flight different?
![Page 4: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/4.jpg)
How do you think moths and
butterflies fly?

Let’s compare bird flight with butterfly flight

Bird bones are hollow. This helps them to be light enough for flight. Bird wings are made up of bones, muscles, skin,
and feathers.
Butterfly wings are solid. They have veins. Butterfly wings are made up of
veins and chiton (the butterfly “scales”).
![Page 9: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/9.jpg)

Butterfly wings are solid. They have veins. Butterfly wings are made up of

If butterflies do not have muscles in their wings, how do they move their wings?
![Page 10: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/10.jpg)
They contract their bodies! - Bees, butterflies, moths, flies, and wasps contract their bodies in order to fly.
- Squeeze your body as tight as you can. Then, release! Can you feel that movement? That is you contracting your body.
- When insects contract their bodies (using muscles), the movement on their exoskeltons makes their wings flap.
- Flapping wings = flight!

Butterflies are symmetrical. You can see their symmetry in the shapes of their bodies and in the patterns on their bodies.
What is symmetry?
![Page 18: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/18.jpg)
The most common type of symmetry is line or mirror symmetry. A picture that can be folded in such a way that one-half of it is an exact reflection is said to have line symmetry.

The two parts of the original pictures are mirror images of each other and are said to be congruent. Congruent means that both parts have the same shape and the same size.

Everyone should now
have 2 copies of
their colored,
symmetrical butterflies
![Page 46: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/46.jpg)
Cut-out the butterfly wings.
![Page 47: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/47.jpg)
Put the sticks in the squishy ball
Get glue ready
![Page 48: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/48.jpg)
Coat both sides of one of the sticks with school
glue
![Page 49: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/49.jpg)
Stick on one of the wings
![Page 50: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/50.jpg)
Cover the back of the wing with
school glue
![Page 51: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/51.jpg)
Find the matching wing, and stick it to
the back of the wing on
the stick.
You now have one
completed wing.
![Page 52: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/52.jpg)
Repeat previous steps and finish the
second wing
![Page 53: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/53.jpg)
If you have any “extra”
white showing on your wings; trim it with the scissors.
![Page 54: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/54.jpg)
You now have 2 totally finished wings!
Your work should look
something like this
![Page 55: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/55.jpg)
Poke two holes in-between
your wings with either a sharp pencil (student) or X-Acto blade
(teacher)
![Page 56: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/56.jpg)
Stick a pipe cleaner in
each hole to make
antennae for your butterfly
![Page 57: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/57.jpg)
Using your scrap paper,
cut two small circles.
![Page 58: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/58.jpg)
Use the black
sharpie to turn the
circles into eyes
![Page 59: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/59.jpg)
Glue the eyes to the squishy ball
![Page 60: How do butterflies flap their wings presentation](https://reader038.fdocuments.us/reader038/viewer/2022103010/5871080e1a28abac6d8b4589/html5/thumbnails/60.jpg)
Use the sharpie to
draw a smile (optional) on your butterfly
