Students explore exercises that utilize critical thinking skills, inductive reasoning, deductive reasoning, and problem solving.

**Design Challenge
**

**Students learn how engineers collaborate to design, test and improve their ideas. Student teams have a period of 18 minutes to build the tallest free standing spaghetti structure that supports a marshmallow.**

After this activity, students understand that even weak materials can be made stronger with good design techniques and they learn the importance of team work in engineering.

This activity is meant to be an experiential introduction to the engineering design process.

"How can a lever make work easier?"

The Gifted and Talented Students in Grades 4 and 5 were introduced to the ancient Greek mathematician, Archimedes,"The Father of Experimental Science."

Although Archimedes did not invent the lever, he was the first to explain how it works. Archimedes theorized that given the right size lever and a place to stand, he could lift an object the size of the earth.

In this activity, students built a first-class lever and used it as a balance. Then, by manipulating the size of the load, effort and length of the load and effort arms, students came to understand the

"Law of Levers" and how levers can make lifting heavy objects easier.

Students were challenged to put the Law of Levers to work by lifting a load of 45 washers with the effort of just 5 washers. Students realized that the closer the load is to the fulcrum, the less effort it takes to lift the load. Through trial and error and problem solving techniques, the students realized that they needed to adjust the location of the fulcrum.
