Scale Models

Science Fair Project Idea

Scientific Method

Many industries rely on scale models to develop new products and designs. Architects, industrial designers, artists, clothing designers, and car manufacturers all use scale models. Each model is built to a scale that relates the actual object to the model through a ratio. Can you determine a formula for constructing a scale model? You can use your formula to make a model of your house, school, neighborhood, or town (CUBE, 2002). You can make scale models of the Wright Brothers aircraft… Read more

Scentsational Memories

STEM Activity

Did you know that approximately 2 million people in the United States have no sense of smell? Lack of smell is a disorder known as anosmia, and can be caused by damage to the nerves that transmit information from your nose to your brain.
