### What You Need

You can make orbs and domes just out of paper! They’ll look cool, and they’re a way to learn geometry — math!

**Materials**:

- Colored construction paper
- Tape/Glue
- Scissors
- Ruler

**Basic Dome Procedure:**

- Cut out 20 circles all of the same exact size and shape (the bigger your circles, the bigger your dome will be).
- Cut a triangle that will fit all three of its corners into one of your circles.
- Set your triangle cut out on top of each circle cut out, and trace the lines of the triangle.
- Put the triangle to the side, and fold your circle along the lines of your traced triangle (making “flaps”).
- Use glue to connect the side flap of one circle, to the side flap of another circle. Make the edges of each circle meet exactly with the other circle.
- Do step 5 with three more circles. It will now look like a dome-shaped object.
- Now connect 5 more circle, so that your object will start to look ball shaped.
- Glue all loose edges together to complete your dome.

**Harder Dome Procedure:**

- Get one piece of paper (the larger the paper, the bigger your orb will be, and the smaller the paper the smaller your orb will be).
- Fold the paper in half.
- Unfold your paper, and take one of the folded sides, and fold just that piece in half.
- Unfold your paper, and fold the top corner of your paper into a little triangle that lines up with the crease in the paper you just made in step 3!
- Keep this corner folded, and then re-fold that same corner so that it lines up with the crease again.
- Do steps 1-5 on the other side of your paper now, except instead of using the top corner, use the bottom one.
- Fold each half of the paper into the center (keep your little triangles folded in still!).
- Take the lower right corner, and fold it up so that it meets the center.
- Do the same thing as step 8 but with the opposite corner.
- Take each flap you just folded (steps 8 and 9), and put them under the folds that are already there (they are underneath, but they are there).
- Flip your paper over, and fold each point into the center.

It should end up looking like below.

[image goes here] - Do this with 30 more pieces of paper!
- Grap two pieces of paper and place one end into the other.
- Take one more piece of paper and place its end into step 13. This is called a peak now.
- Keep making peaks, and attach them to each other and soon enough…
