Does gold really boil? Learn what temperature gold boils at and more using an animated activity about the properties of matter. Scientists learn about the properties of matter including examples of physical properties, the effect changes...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

"I don't want change; I want swiss!" As Willy Loman bemoans in Arthur Miller's Death of A Salesman, accepting change can be a real challenge. The aim of this session is to encourage class members to see the naturalness and...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Is it really that big of a deal if the global climate undergoes a little change? Young environmentalists consider this very question as they discuss in small groups the impact of different climate change scenarios on their lives,...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

Learning to embrace the opportunities and challenges change presents is the focus of the exercises and activities in this fifth session of a 10-lesson course on Social, Physical, Emotional, Cognitive and Spiritual (SPECS) health....
