How to Find a True Circle?

  • September 9

At the Texas Lodge, we studied the pavers around the flagpole. If you look closely, you may wonder – do these pavers actually make a circle? How can we determine this?

How Many People Can Fit on the Observation Deck?

  • September 9

At Camp Whispering Cedars, Girl Scouts climb a winding series of steps to reach the top of an observation deck, where they can stargaze or have meetings. We wonder how they might estimate exactly how many people could have fun stargazing sleepover party on the deck!

How Can You Enquire Like a walkSTEM Explorer -2?

  • September 9

At the Lisa K. Simmons Amphitheater, we notice interesting things and brainstorm a variety of questions grounded in our observations. This is an opportunity to practice the fascinating, easy-to-do, and important skill of noticing what's around you and brainstorming STEM-related questions grounded in your observations. This represents the most important aspect of what our Mathfinder and walkSTEM community is all about! Supplementary Activity Guides for this video to extend student learning for K-...

What is the Slope of this Staircase?

  • September 9

We explore how to use slope, the ratio of height to horizontal distance, to better understand how stairs are designed based on international building codes to keep us safe.

Welcome to the Frontiers of Flight Museum

  • September 9

Welcome to the Frontiers of Flight Museum in Dallas, located close to Love Field Airport. This museum is located in an old aircraft hangar. As we look around, we notice diverse designs of the varied aircraft in the museum.

What is the Highest Point on the Swing?

  • September 9

Scouts love visiting Camp Whispering Cedars for its amazing ropes course – great for bonding and pushing new boundaries! The course features a zip line, ropes bridge, climbing wall, and a towering three-person swing. The swing made us wonder – exactly how high is someone pulled to start the swing? In order to figure this out, we use shadows and similar triangles. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here:...

What Size is the Sports Field?

  • September 9

We visited the Staubach Sports Field to determine if other teams could use the field for a regulation sports game. We use non-standard units of measurement, like arm span, to estimate the length of the field.

What Volume of Water can the Rain Barrels Hold?

  • September 9

At the Crystal Charity Ball Exploration Center at Camp Whispering Cedars, where Girl Scouts can marvel at plants growing on the building, you might notice from the video that the roof is sloped. Gravity pulls rainwater toward the front of the building, where the water falls into the gutters. From the gutters, the water is moved to plastic rain barrels, at the corners of the building. What an amazing example of sustainability and conservation efforts at work! We consider exactly how many toilet f... CONTINUE READING

How Big is the Pool?

  • September 9

Ever look into a pool and think, “Wow – that’s a lot of water!” This thought prompted us to consider exactly how many showers one could take using water in the pool at Camp Whispering Cedars. We started by measuring the surface area and perimeter of the pool before determining volume, using the formula, Volume=(Area)(Height). You’ll be amazed at what we discovered!

How to Measure Change in Musical Pitch?

  • September 9

We love playing the xylophone at the outdoor Soundscape. It's both fun and also a great opportunity to really understand what we mean by frequency or pitch. Also, we wondered if there is a mathematical relationship between length of bars and pitch. Finally we got to explore what happens to pitch when we played xylophones made of different materials!
