Is a career in Geophysics in your future? Geophysicists like STEM Gem Debbie Lawrence use math to create visual models of what lies beneath Earth’s surface. The models are used to decide where to drill for water or hydrocarbons, such as coal or natural gas. She compares her science to piecing together a puzzle or cracking a code. Watch one of the videos. Then, with your STEM Gems Tribe, discuss, explore, reflect, and act.
