|Title of Presentation or Activity
|Break it Down-Weathering and Erosion
||This lesson plan allows students to learn about the processes of weathering and erosion and how those processes shape the landscape.
|Bridge Building! Testing Structural Stability of Bridges
||In this activity, groups of students will use visual aids of bridges around the world and their creativity to build various bridges of spaghetti and marshmallows. Each group will then test the strengths of their bridges to come to conclusions on the characteristics of strong and stable bridges.
The Activity Plan is found in the StructuralStabilityActivityPlan.doc file. Two worksheet files are provided, both are the same sheet, just in different programs (Word and Excel). The 4th file is a set of bridge pictures for use in the activity.
|Bridges - how and why they work
||The purpose of this lesson is for students to learn basic workings of three simple bridges: beam, suspension, and truss. In a hands-on lab project, students will use their knowledge of these bridges to create similar structures out of the every-day items they are provided. The students will then have to label the direction of the forces working on the bridges on a separate worksheet.
||Take the most timeless classroom taboo and turn it into a hands-on activity to explore the scientific method and a possible introduction to the use of balances. Bubblegum on the market (not sugar free) can consist of up to 75% sugar. The sugar provides the short-lived flavors of bubblegum, and disappearance of the flavors is a result of sugar being dissolved in your mouth. Comparing the mass of gum before and after being chewed will clearly demonstrate how much of a single piece of gum is actually sugar.
|Building a Cell
||This activity is designed to introduce students to the differences between prokaryotic and eukaryotic cells.
