2. in this step of the engineering design process, you test your device
3. the rate of change of velocity per unit of time
6. in this step of the engineering design process, you create multiple solutions and then sketch one out
9. is the use of aircraft to distribute seeds to replant forests.
10. Soil made up from really small particles. It holds water the best of the three types.
12. in this step of the engineering design process you research the problem
16. the rate at which someone or something is able to move or operate.
17. Light bouncing off another object
19. in this step of the engineering design process, you make improvements to your device

1. Light being taken in and turned into heat energy
4. acronym for what plants need to survive
5. Soil made up from weathered rock
7. in this step of the engineering design process you identify criteria and constraints
8. Soil normally found near rivers or streams. It is very fertile
11. Light passing through a clear object
13. in this step of the engineering design process, you share important information about your project.
14. it is a combination of sand, silt and clay such that the beneficial properties of each are included
15. in this step of the engineering design process you repeat the process until you meet the criteria and constraints.
18. in this step of the engineering design process, you build your solution
20. Light bending and changing speeds while going through an object
