How tall is your Christmas tree? Or any tree for that matter?
Use this fun and super easy STEM activity to find out any tree's height without a ladder. It relies on trigonometry!
1. Get on your knees and put the top of your head on the floor.
2. Look through your legs at your tree. Can you see the tippy top?
3. If not, move away from the tree until you can.
4. Mark the spot where your head is touching the ground.It's the same distance from the tree as the tree is tall!
