ABOUT THE SOUND PICTURE

With mouth wide open, vibrating air coming up the throat from the vocal chords leaving the open mouth and spreading in all directions. Hi, I am Janice VanCleave, author of 50+ best-selling science experiment books for children ages 4 through high school. I taught science for 27 years and now am creating this science website.   My scream was not staged. The picture was to be of two adult cats, which I was holding. A microsecond before the camera snapped, the two cats dug their claws into my skin as they prepared to leap out of my arms. A picture like this is great for making inferences. Kids could make "guesses" as to why I am screaming. They would be drawing on facts from the photo, such as I look like I am in pain or maybe I am just pretending.

Testing the Strength of a Thigh Bone Model

By Janice VanCleave

Strength Testing of Thigh Bone ModelThe long bone in your leg, called your thigh bone, is shaped much like the bone in a chicken’s leg. Both have a hollow, cylinder-like shape, which means they are shaped like a tall soup can.This shape makes the leg bone lighter than it would be if it were solid throughout.

Discover For Yourself

The long, yet cylinder-like shape of the thigh  leg bone is strong.

Use a sheet of copy paper to make a model of a thigh bone.

1. Roll the paper into a tube, and then overlap the edges and securing with tape.

2. As shown in the photo, draw the shape of a thigh bone on the paper.

3. Test the strength of the paper thigh model  by standing the paper tube on a table, and then lay a book on top of the tube. Add more books to test the strength of the tube.

Paper Thigh Bone Supports Books

The photos shown on this page were taken by Amida, the webmaster of Unschool Me. Amida’s sons prepared the bone model and performed the strength tests using books and even a stuffed elephant.

How many books will your paper thigh bone model support?
