What are simple machines? How do we combine simple machines to complete complicated tasks? We have read about a potato chip factory, and we are now producing systems to get our potatoes from the truck up to the work floor using the least amount of effort. What? Least amount of effort? Not only low effort, but no mashed potatoes!
Important words include:
Newtons, lever, pulley, effort, load, and fulcrum.
Homework:
All students should have brought home a full page explanation of the Rube Goldberg home project. It is due May 4. This is a building experience, and many families join in the fun. The scoring rubric is on the back.
Would you like to spend some quality time in the science classroom? After simple machines, we will be studying everything birds. We need adults to work with small groups to put together booths for our Bird Expo that takes place at the end of May. It will require 3 days in the classroom and attendance at the expo. If you are interested, please email Ms Hill.
Rube Goldberg Lives on!
Design your own Rube Goldberg machine!
-Find a simple task that you do every day
-Design at least five steps to complete the task
You have many options in completing this task! (CHOOSE ONE!)
All projects must include written, step- by- step instructions. You must use numbered steps. You also must have capital letters, punctuation, and correct spelling. Have someone proof your written work before you hand it in!
Be creative! Have fun!
You must have at least five steps. You may choose to work in groups of up to four students. Add 3-4 new steps for each student in your group. You need to label your parts. The machine needs to complete one simple task. You need to use more than dominoes! Dominos can be used in only one step. Use color.
DO YOUR BEST! USE YOUR SMARTS!

I was unable to copy the rubric in the grid. The 0-4 are vertical instead of horizontal. Grade level expectations: 3
Scoring rubric for ’Rube Goldberg’ Project
0 1 2 3 4
Steps in machine
Not present
Attempted, are not all working or usable
Has 5 working steps (+3-4 for each group member)
Same as 2 with increased # of steps or complexity
Includes all of 3 and goes well above and beyond requirements for project.
Labeling of steps
Not present
Some labels, not covering every step or some labels incorrect
Each step labeled, no errors
Same as 2 + color used and shows small details
Exceptional quality in labeling and their placement. Includes all of 3.
Presentation
Not present
Some labeling, does not show steps clearly
All requirements and shows steps clearly, has minimum requirements completed
Machine is carefully completed, is easy to follow and
is presented clearly
All of 3 and is exceptionally above what a 5th grader is expected to do. Exceptional work in all areas
Step by step instructions
Not present
Has information but is incomplete or not in correct order
Has complete information, errors in numbering or description of steps, spelling or grammar
Steps are clearly written with no errors, includes description
All of three+ steps use exceptional description allowing someone to follow without seeing machine
Rubric grades show progress on specific skills. Letter grades are based on rubric but include teacher appraisal of the finished project. There is a 10% drop in grade for late projects.
Are you falling behind in your homework? Do not rush to get something done- you may forget important information. Instead, set aside some time to really concentrate on your assignments. You will be glad you did!

Rube Goldberg Lives on!
Design your own Rube Goldberg machine!
-Find a simple task that you do every day
-Design at least five steps to complete the task
You have many options in completing this task! (CHOOSE ONE!)
- Create a detailed drawing of your machine. Include labels for all of your materials, and detailed labeling explaining how the machine works. You must use medium size poster paper or tag board. Include your instructions on the back of your board. You may not use computer-generated pictures.
- Create a large Machine and use video or pictures to show your machine working.
- Build the machine and present it to the class. Ask parents first before building something that you will need help in transporting.
All projects must include written, step- by- step instructions. You must use numbered steps. You also must have capital letters, punctuation, and correct spelling. Have someone proof your written work before you hand it in!
