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.

Scientific Method:Cleaning Kitchen

By Janice VanCleave

teach-young1Notes from Janice’s Desk

I’d like kids to use the scientific method instead of just defining it and listing its steps. The scientific method is a valuable life-skill tool that is used in solving everyday problems. It is especially useful in emergencies.  For example, I got a call from a local TV reporter that she and her recording crew would be at my house in about 30 minutes. I had misunderstood and was expecting her to call and schedule a time for the interview. OOPS!! I was in my sweat pants–hair a mess and no make-up. I figured I could get myself ready but my house was not in order. It was PANIC TIME!!!

Problem: How do I make myself and the house presentable for an evening video on TV in 30 minutes?

Hypothesis: I could hardly thing much less come up with a plan. But my husband was very clear headed and if I could make myself presentable, he could take care of the house. Basically his hypothesis was that if we divided the chores we could get though on time. Must admit that I wasn’t sure about him completing his part. He much prefers plowing or building something. But I had no choice.

Experiment–Investigation–This part was the actual processes done to test the hypothesis. In other words, what was done and did we finish on time?

Results: I was pleased with how I looked and the rooms visible to the TV reporter and crew never looked better. Now how did he get the dishes done and everything so clean? I forgot to tell you that we wash our dishes in the sink–no dishwasher.

His secret cleaning method involved cleaning off surfaces by putting things in the bedroom and closing the door. Surfaces were quickly wiped leaving only a few items for display. Floors–we have tile so he quickly swept the rooms. But what about the kitchen? His solution was to put all the dishes in his pick-up truck, and then drive it out to the barn. Wipe off the counters and voila’ —the kitchen is sparkling clean!!

Conclusion: First, I need to make sure that I understand when and where interviews will be made. Second, I have a great husband who can pull my fat out of the fire in emergencies. YEA!!!!  This is not the first time he saved me, but it is one of his more creative rescues. He has had a bit of practice– We are celebrating our 50th wedding anniversary today–Aug. 29, 2009.

FYI: The interview went well and the video made looked great on the evening news.

For more information about using the scientific method, see OBSERVATIONS.
