Juan Martinez-Day 3-PLTW Notebook

Well today in the morning we presented our power point that we were working on yesterday.  We presented and so did every other group as well.  I believe we did well and so did every one else.  We also had to create another power point.  It was on the calculator how it was invented and what impact it had on the world.

1.      Define and differentiate invention and innovation.

 An invention is an item that an inventor came up with.  An innovation is a design that was made better than the original.  

2.      What were the major factors that contributed to past innovations of the invention that you researched?

 Innovation was one major factor.  Innovation made the calculator way easier and basic than it was before.

3.      How has the pace of development changed through the history of the design?

 The pace has maybe slowed down because the calculator has all the necessities it needs.  So, maybe someone would add something interesting to it someday

4.      What future innovations to the chosen invention do you predict?

I predict maybe a camera being added being able to scan a word or number problem on a piece of paper not having to put the numbers in with ease.
