Champions Build Marshmallow Towers!

Using just 50 toothpicks and 25 small marshallows, students were given two challenges:

1. How tall of a stucture could they build?
2. Could they build a structure with at least a three inch base that could support a standard box of Crayons?

Students were given 20 minutes to enginer their structures. They were able to build some very inpressive (and tall) sturctures. The highest was ten inches!

Most were able to build their stucture in a way to support a box of crayons.

Our last step was reflecting on what what we learned today in a short refelction essay.

Well done Champions!

Champions Build Extension Grabbers!

Today students were given two rulers, two feet of tape, two feet of string, 2 rubber bands, and a paper clip. The challenge was to engineer an extender that could pick up a few items from two feet away. The items were a pencil and a full box of crayons.

First we had a VTS discussion after looking at some images of "extension grabbers" and how they can be helpful in everyday life. Next, students were given the materials and time to engineer, test, and modify. Most students were able to meet the challenge. Once they were successful, they were encouraged to add another ruler for a further reach. One student was able to successfully reach from four feet away (4 rulers) with her extender.

Our last step was to reflect on what we learned in a short essay.
Well done Champions!
