Physical Science Overview:

This Physical Science introduction to formal science provides preparation for high school Biology, Chemistry, and Physics. Students will study topics such as air, the atmosphere, water and the hydrosphere, the structure of the earth, weather, atoms and molecules, the physics of motion, Newton’s laws, work and simple machines, electricity and magnetism, sound, light, and nuclear energy. Students will learn how to take measurements, keep experimental data, and to compose a proper technical lab report.

Melissa Lopez

Melissa Lopez went to college at Baylor University where she studied biology and chemistry. Studying science at a Christian university allowed her to appreciate both God’s work in creation and His relationship with us. After college, Melissa worked in a medical research lab studying cancer targeting; then, God called her to teach. She taught in public schools for 9 years and has been teaching at local homeschool co-op for four years. It has been amazing to watch God create so many unique educational opportunities; online teaching is another way to teach for God and connect with students.

Melissa Lopez has been married to her husband for 14 years, and they currently live just outside of Dallas, Texas. They have three boys that they are currently homeschooling, so life at the Lopez house is never boring or quiet. Melissa Lopez is a member of Lakeshore Church in Rockwall, Texas. This year Melissa Lopez is looking forward to getting to know her students and helping them be as successful as they can be.
