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.

Click Beetles

By Janice VanCleave

Notes from Janice’s Desk

This morning, while trying to retrieve a kitten hiding under the couch, I discovered a click beetle. This find changed my plans for the day. With kitten outdoors and beetle in a jar I proceeding to my office to start the beetle’s photo shoot. Surprisingly the beetle was relatively still as I snapped its picture from different angles. But during the transfer from the paper to the jar the beetle clicked and the chase began but the beetle got away.  I not only lost the beetle, but lost all the pictures of it because I had forgotten to put the memory card in the camera. But alas, I found a short video on YouTube. In fact the beetle in the video has luminescent spots. How cool is that!! Now you can see what happens when a click beetle clicks. To learn more about this funny bug as well as fun activities, see CLICK BEETLE.
