9.  **flower:** A flower is the part of a plant that makes seeds.
10. **force:** Force is a push or pull used to put something in motion.
11. **fossil:** A fossil is what is left of a living thing from the past.
12. **friction:** Friction is a force that slows down moving things.
13. **fruit:** A fruit is the part of a plant that keeps seeds safe.
14. **fuel:** Fuel is something that gives off heat when it burns.
15. **geologist:** A geologist is a scientist who studies rocks and puts them into groups.
16. **germinate:** When a seed germinates, it begins to grow.
17. **gravity:** Gravity is a force that pulls things toward Earth.
18. **hardness:** When you describe a rock's hardness, you describe how tough it is.
