The Brown Bag STEM Challenge II- Derby Cars

For this week, I thought we’d explore the use of derby cars to teach STEM.  Not the pinewood kind that the boy scouts make, but a variation of that using a clothespin as the car body.  In this challenge, students will each build their own derby car, but will work with a partner for support.  Students are challenged to design the derby car that will complete the “track” the fastest.

Students can build their cars using any of the materials.  Generally, students will place the front axle in the hole at the front of the clothespin and the second in the back somewhere, securing it with tape.  However, there is no rule that the clothespin must be the body.  Students can construct their derby car however they like. So, on your mark, get set, create!

So, what did we learn?
Next Generation Science Standards: Developing and Using Models, Planning and Carrying Out Investigation, Obtaining, evaluating, and communicating information ; CCC- Scale, Proportion and Quantity Cause and Effect

CCSS Math: Operations and Algebraic Thinking, Measurement and Data, Expressions and Equations

The Brown Bag Challenge II- Pringle Pod

I always thought that the Egg Drop was a really cool project.  You know, the one where you design a protective pod for a raw egg and then drop it from a balcony to see if it worked?

Fantastic…until you factor in the children and well, the actual raw eggs.  Then it all goes downhill rather fast.
So I’ve been thinking of ways to modify this activity so that it is more sanitary and less messy. Voila! Pringle Pod.

Following their criteria and constraints, students work in pairs or teams to construct a protective pod for their pringle.  The criteria for success is the same as the Egg Drop- that the pringle will not break.  Great challenge…with a lot less mess!

So, what did we learn?

The Brown Bag STEM Challenge II- Perfect Parachutes

What could be more fun than designing the Perfect Parachute? In this STEM challenge, students will work to design the parachute that stays aloft the longest.

In this challenge, students will need to keep their cargo  aloft the longest, so be sure to provide a surplus of materials to support multiple parachutes per student or pair. I also like to provide different types of paper, string, and tape so that students can learn about how weight and other different characteristics affect a parachute.

Once students have finished a design they should test it and collect data.   Safety takes priority, so I don’t allow them to stand on anything but their own two feet to test. As a result, I specify that they test from the height of 48″ (which is about how far my students can reach without standing on anything).

So, what did we learn?

The Brown Bag STEM Challenge II- Paper Rockets

This week’s activity is a low-budget, fun way to launch rockets with students.  This challenge stresses data collecting, data analysis and is a good way for students to experiment with controls and variables.  No launcher is actually used, so it can be done in any space.

Students work in pairs to design, build, and “fly” straw rockets.  Students wrap a strip of paper around a pencil, overlapping it as they go.  Once students have completed their rocket bodies, additional paper can be used to design fins for it.

This versatile activity is great for a wide range of age groups because students can experiment with many facets of the rocket such as the fins and fuselage.
