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.

Science Fair Projects: Botany

By Janice VanCleave

plant-progress1

Notes from Janice’s Desk

In the United States, science fair projects generally start in autumn. Even though this is not our plant growing season indoors plant projects work very well.

Botany is the study of plants. The picture shows tomato plants grown from seeds planted at different times. This is one way to compare the growth of plants. For very young learners it not only allows them to visually compare plant development, but it introduces or reinforces time sequences.

Instead of planting the seeds at different times, photographs can be taken to show the development of the plants during specific periods of time. It is important that the experiment be repeated four or more times. To do this, prepare four or more identical containers of soil and plant seeds from the same seed source in each. Make sure that you treat each container the same. Meaning that they get the same amount of light, water, etc….

For botany science fair ideas, see BOTANY.

Janice
