68. Try this: Leaning towers.

Author

McRae, Mike

Subjects
*SCIENTIFIC experimentation, *OPTICAL illusions, *DIGITAL cameras, *TALL buildings, *PHOTOGRAPHY
Abstract

The article describes an experiment related to creating an illusion of a leaning tower using a digital camera. A list of materials is provided, specific procedures and practical applications. It is explained that the brain has something to do with interpreting one of two identical pictures as leaning more than the other.

71. Try this! Burping bugs.

Author

McRae, Mike

Subjects
*SCIENTIFIC experimentation, *PHYSIOLOGICAL effects of temperature, *CARBON dioxide, *YEAST, *MICROBIAL respiration
Abstract

The article presents a science experiment that demonstrates the impact of temperature on the amount of gas produced by a microbe-like yeast. The materials needed and the step-by-step procedure in implementing the experiment are detailed. It explains the process of aerobic respiration, production of carbon dioxide gas and production of energy in yeast. The role of temperature in the function of yeasts and bacteria and its implications for food preservation are also explained.
