Product Description
This is a 4-5 day center. The resource is 4 worksheets (some 2-sided) that contain explicit instructions on what to complete at each center. In addition to the worksheets you will need 4 tubs with the following materials.

Center 1 - Famous Structures Internet Scavenger Hunt.
Expectation 3.2
For this center students will need access to computers or iPads and a basic understanding on how to google for information.

Center 2 - Natural or Man Made?
Expectation 3.2,
In this center students read about the difference between natural and man made structures and then decide together if the listed structures are natural or man made. For the second part of the activity they will need magazines to cut up, scissors, glue and either chart paper or bristol board.

Center 3 - Increasing Stability.
Expectation 2.1, 2.6, 2.3
Here, the students are guided through an experiment where they are encouraged to try increasing the stability of a paper tube. I usually put dried beans (or rice), elastics, tissue paper, scissors and glue in a bin with the sheets and the paper tubes (paper towel or toilet paper). For this center they would need a basic familiarity with the scientific method.

Center 4 - Material Properties
Expectation 3.5,
This center requires you to put any 3 objects into a bin. Last year I put in a diaper, a winter boot and a child's metal spinning top. I tried to pick objects with different materials. The students work with the idea that different materials have different properties, and that some properties are better suited to an object than others.

What I do is I put everything in the tubs the day before and photocopy the sheets. I put the sheets into a big envelope and toss them in the bin that goes with the sheets. Then I make the groups up. The day I intro the centers, I review center/group work expectations and post them for reference during the week.
I then read through each center with the class and explain briefly the task. Then I divide them up and they get started. Usually I spend so much time on establishing the set up the first day that we need a whole other class (the next day) to get through the first center.

The kids honestly love these. I usually walk around and chat with them and help them if they're feeling stuck, but usually I find they're so engaged I don't need to do much.
