VanCleave's Science Fun

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.

Polymer Activity Using Beads

By

Polymer Model

A polymer is made of many monomers linked together.

monomer: A single unit; a single molecule.

The diagram represents a model of a polymer. While actual polymers can be made of thousands of monomers, the model shown has only eleven.

The monomers in the diagram are different colors and sizes of beads on a black string. The string is tied to make a polymer necklace.

Teaching Tip

Using beads and string, kids can make their own polymer models. Any and all bead sequencing should be acceptable as long as it is original. The only restriction that I suggest is –NO DUPLICATE POLYMER MODELS.

Have Fun!
I would love to see pictures of the different polymer models.
