- 14. The dustpan is an example of an inclined plane. The inclined plane of the dustpan allows the dirt to go into the pan easier. If the dustpan wasn’t and inclined plane it would be harder to get the dust into the pan. Back to Test Your Knowledge
- 15. The scissors are an example of 2 different simple machines. They are a lever and 2 wedges. They are a lever because the fulcrum is where the 2 arms connect and the levers are the silver parts. It is also has 2 wedges. Both of the cutting surfaces are two inclined planes put together to form a sharp edge. Back to Test Your Knowledge
- 16. This cart is an example of a wheel and axle. The wheel and axle of this cart allows the user to get the boxes from one place to another. If you look between the front wheels you can see the bar that is the axle. Back to Test Your Knowledge

- 25. Home • The purpose of this PowerPoint is to inform 3rd grade students about simple and compound machine. The content is meant to inform students in a simple, yet creative way. The information being presented is put into small chunks with videos to add to the educational experience. • I feel that the biggest challenge I faced while doing this assignment was time. I procrastinated, again, and found this assignment to be more time consuming than I had anticipated. However, I am very proud of the work that I have accomplished. • I found my biggest success to be that I incorporated a lot of the tools that I had learn throughout the semester. I used photo editing, made my own pictures, used audio and video, and was able to make an educational and interactive PowerPoint that I will be able to use in the future.
