We are now going to do a team activity regarding called “The World’s Ten Greatest Inventions.”
With your team, you are to complete what your team believes are the 10 greatest and must be able to support your reasoning on the lines provided on your handout.
Work cooperatively, collaboratively and creatively!
Is it important to be famous? Did Ruth Wakefield know she would be famous for her Toll House Cookie?
Michael Jordan for his patents on shoes, clothing, and fragrances?
Without Ralph Samuelson, we may not have water skis!
Thanks to Ruth Harden for creating Barbie!
The cotton gin, by Eli Whitney, is historical.
Did Margaret Knight realize that her paper bags are used around the world?
Next Steps
It is important to know that engineers often improve things or make things better. For example, we have always needed transportation. However, we are not going to hop up on a horse to get to school! We walk, take the bus, or get a ride in a car, truck or van.
Now, let’s take a look at our “Speedy Inventions” activity. Let’s read the directions together and discuss how to calculate the correct answer and then graph it correctly. We will do the first one together.
It is important to gather data and to be able to organize the data in a way that can be understood and used by others. In this activity, you are making a bar graph and then will have questions to answer about it.
HOMEWORK: Finish Speedy Inventions sheet and read the article “History of Bridge Development.” Also take time to actually meet an engineer online. See handout with the websites.
