The time before written records is called prehistory. Even though there aren't written records there is still information about the world from long ago. Using a chemistry process called carbon dating, scientists can calculate the age of ancient remains of plants, animals, and even humans! In this one-time class you will learn about chemistry basics, draw an atom, and listen and discuss as I explain how chemistry helps us learn about ancient history! The lesson will involve: ~ Watching a slideshow to see basics of chemistry and carbon dating ~ Listening as I explain how the science of carbon dating works ~ Drawing a diagram of an atom and a diagram explaining carbon dating ~ Writing a couple of notes about chemistry vocabulary words (optional) ~ Discussing the uses of carbon dating
學習目標
Learners will know the parts of an atom, what "nuclear" means in chemistry, and be able to explain what atoms have to do with calculating ages of things using carbon dating.
其他詳情
父母的引導和規範
I will briefly refer to the use of carbon dating to determine the age of ancient human remains. I do not include any pictures or specific examples of ancient remains, but if learners ask I will provide information about some famous finds.

I specialize in finding fun twists to standard curriculum to help my students build critical thinking skills as well as scientific knowledge. By adding a new twist to a familiar topic we can expand our thinking to include new possibilities. I have taught science to homeschool students for the last 16 years and during that time I have developed many teaching techniques and hands-on projects to help students explore concepts in new and exciting ways.評論
