Gold Medal STEM – Friday: Let’s Race

Gold Medal STEM – Friday: Let’s Race

Swimming-a fish’s mode of transportation. We sometimes take our fish-like ability for granted. Yet, have you ever seen a mechanical swimmer? Today students were able to use their engineering skills to make mechanical swimmers and race them against each other. Students observed their work come to life and were able to further develop their problem solving skills by suggesting new ways of improving their mechanical swimmers!

Gold Medal STEM – Thursday: Egghead

Gold Medal STEM – Thursday: Egghead

Did the egg crack? Ask your students and find out how their group did! Today in class the students worked on making a helmet for an egg, so when the egg was dropped it would not crack. Students used plastic spoons, Styrofoam cups, and flexible cardboard as the harder surfaces, while others used bubble wrap cotton materials, and moldable fiberglass.  Some trials were definitely messier than others, but it was all for science!

Ask your students:

Did their egg crack?

What materials did you use?

How did you pick those materials?

Gold Medal STEM – Wednesday: What’s Your Vertical?

Gold Medal STEM – Wednesday: What’s Your Vertical?

Today, our Olympic scientists examined the math and physics behind the standing vertical jump. Students especially focused on determining the knee angle that will produce the highest jump, using a special instrument called a goniometer to measure it. Our sports scientists then used their measurements to determine a graphical relationship between force and time during the jump.

Ask your student:

What knee flexion angle did you determine was the best for vertical jumps?

What other sports might use motions similar to those in a vertical jump? (cycling, swimming, weightlifting)

 

Gold Medal STEM – Tuesday: Mechanical Swimmer: Materials Analysis

Gold Medal STEM – Tuesday: Mechanical Swimmer: Materials Analysis

Our Olympic engineers were able to analyze the necessary materials for a mechanical swimmer. Bags of materials were categorized by their characteristics and functions. Once they had an understanding of the parts, our students created poster diagrams to display their ideas about the best use of the materials. Everyone shared their analyses to the class by doing a gallery walk.

Ask your student:

What are some material categories? (Adhesives, platforms, buoyancy, support, measurement)

Which materials might have more than one application? How could they also be used?

Gold Medal STEM: Monday

The focus of one of today’s lesson was motion. However, students did not just learn what motion is, but rather how to record, measure and mathematically analyze motion. Using distance, time, and speed variables, our “Gold Medal” mathematicians developed graphs based on data they collected using a Calculator Based Ranger (CBR) and graphing calculator. Students learned which motions would cause changes in their graphs, as well as how to predict what graphs would look like based on how fast, far, or long they traveled.
