Seasonal Disease Outbreaks

Science Fair Project Idea

Scientific Method

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

Seasons Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

Seawater Science: Model Ocean Currents in Your Kitchen

STEM Activity

Have you ever wondered what causes ocean currents? Ocean currents have profound effects on the climates of the continents, especially those regions bordering on the ocean. For example, it’s thought that the Gulf Stream (a warm current around the North Atlantic Ocean) makes northwest Europe much warmer than it would otherwise likely be. In this science activity, you will model the behavior of these “rivers” of hot and cold water within the ocean to find out how temperature… Read more
