We now offer the Cool It! card game in our Science Store. Cool It! is the new card game from UCS that teaches kids about the choices we have when it comes to climate change.

Creating Elements up to Iron

When the temperature in the core of a star reaches 100 million degrees Kelvin fusion of Helium into Carbon occurs. Oxygen is also formed from fusion of Carbon and Helium together when the temperature is this high.

When it gets even hotter in the core of the star other elements can be formed. These elements are Neon, Sodium, Magnesium, Sulfur, Silicon, Nickel, Cobalt and Iron. Have you ever heard of any of these elements? (hint: Sodium is found is something you eat...).
