Strengthening Rigor in STEM: Putting the R in STEM...Wait, What?

As we embark on our journey to make our children and students more critical thinkers and problem solvers, we often come upon really fun activities for students to engage in.  (Those who know me are cringing because they know how much I hate the word "fun". Fun implies that nothing is being learned, so I much prefer the word "engaging".)
Unfortunately this hazard transfers to students because the engaging activities that we're asking them to participate in really are...um, well, fun.  And that's great, but we want to make sure that we don't lose site of the goal to learn so we need to introduce our R into STEM- Rigor.

How do you Strengthen Rigor in your STEM projects?  In this series, we'll explore different ways to keep students engaged yet ensure that they are learning and stretching both in content and STEM Skills.

STEM Skills Challenge- Spacesuit Spuds

As we focus on STEM skills that can be achieved through short (or long) duration projects, we're aiming to develop skills that employers are seeking.

According to The 9 Attributes Every Employer Desperately Wants, Forbes magazine examines the skills that make a candidate great.  Among the list, some great core STEM skills like natural curiosity, uncompromising excellence, unlimited versatility, self-awareness, and creative problem solving.

This week's challenge allows students to explore the thee core STEM skills as the explore high-impact space debris by designing and building a spacesuit for their astronaut (potato) and testing its effectiveness.

STEM Skills Challenge- Crazy Catapults

Even though the STEM acronym stands for Science, Technology, Engineering and Math, there are a wide range of skills that this acronym encompasses.

Employers are quick to mention that these are the core skills that they are starting to look for in well qualified candidates. Those "soft skills" are the focus of the STEM Skills Challenges.

This week, students will work with partners to design and build a catapult that will launch mini marshmallows towards a designated target.  In this challenge, students will need to make good materials choices as they can only use three of the four materials provided.  As students experiment, they will work to build a reliable and well-designed catapult, but also establish consistency in hitting a designated target like a bulls eye.  (Teachers may also wish to use small pom poms instead of mini marshmallows.)

10 Easy STEM Projects for Engaging Students- The Brown Bag Challenge II

This Brown bag series gave me a chance to dig through my files and share some more STEM Challenge oldies-but-goodies.

In each post, I've shared different engineering design projects that are appropriate for a wide age range.  All of these activities work to prove that you don't need an endless budget to teach STEM and promote STEM principles and skills.

Here's a recap of the project ideas shared in this series:

The Brown Bag STEM Challenge II- Hot Air Balloons

This challenge takes a little more time than some others, but it is worth it to watch students build a "stock" hot air balloon then work to design their own hot air balloon that stays aloft longer.

Materials
Tissue Paper
Glue Sticks
Scissors
Copy Paper
Staplers
Hair Dryers (with "low" or "cool" setting) OR
Hot Air Popcorn Popper
Stopwatches

In this challenge, student begin by building the same hot air balloon.  I like to have teams of three for this project, simply because it is more involved and requires students to follow specific directions for this first round. I'm also a bug fan of assigning jobs, so I prefer to divide up the work like this:
  • Navigator- Reads the directions to the team
  • Surveyor- Makes any measurements and checks work
  • Manufacturer- Glues, and assembles materials
  Directions can be found all over the internet.  I personally like the Junior Balloonist plans or the directions provided by the Civil Air Patrol (who use the directions from Pitsco).

Students follow the directions to build this balloon using the directions and test it, being sure to record their "flights" using 30 seconds of hot air. Once students establish a time to beat (I usually let each team launch once and average their times to get the time to beat.)

Then, students will design their own hot air balloons striving for them to stay aloft longer.

The Brown Bag STEM Challenge II- Slingshot Gallery

Have you ever played the shooting gallery game at the carnival?  Here's a STEM twist on that carnival game for students...a slingshot gallery.

Materials
Slingshot Targets*
 Rubber Bands
Craft PomPoms
Popsicle Sticks
Tape
Other Fun Found Objects

*Download the Slingshot Targets sheet and photocopy it onto cardstock.  Students will cut the targets apart and fold them to test their slingshot designs.

For this Challenge, students are tasked with building a working slingshot that will knock down the designated targets from a distance of 60 cm (24 inches). Students can work in pairs, but I like each student to design and build their own slingshot.  It shows more ownership and also results in each student having their own data to analyze later.

In addition to establishing a required distance to "fling" from, I like to also require other parameters based on age group (Everyone must use at least 4 different supplies.) or based on available supplies to increase the difficulty (Everyone must use a paper cup in their design.) Adjusting these parameters allows me to differentiate the challenge, even within the same classroom.

So, what did we learn?

Thinkrolls

Thinkrolls is a super fun and unique educational mobile app (iOS/Android) designed for kids 3-8 yrs old.  This app helps students develop cognitive thinking and spatial ability by rolling a ball through a maze while trying to solve puzzles and collect O's.  This game is divided up by chapter and as a student progresses the game will get more complex as skills build upon each other in different areas of a Science such as: gravity, speed, friction, etc.

I highly recommend checking out Thinkrolls by clicking here!!!

*The game will be released this Thursday Oct 16th.

Below is a brief demo video...

The Brown Bag STEM Challenge II- Lilypad Launch

In this challenge, students are asked to design a mechanism that will hold a lilypad and help a "frog" jump up into your hand!

Materials
Plastic Eggs
Frog Patterns
Transparent Tape
Paint Stirrers (Wooden Rulers or similar)
Empty Water bottles
Other found items

Students work in pairs to construct a mechanism that will launch their plastic frog to a height tall enough that a student can catch it.  Students first construct their frogs by cutting out the pattern and taping it to the front and back of the egg.  They should bend down the frog legs so that the frog sits on the lilypad.

Using the supplied materials, students can construct their mechanism.  Most students design a sort of see-saw/catapult contraption using the ruler or the paint stirrer, but the items provided by the teacher may frame the challenge differently.

So, what did we learn?

STEM Skills Challenge- Gumdrop Bridge

Employers today are looking for students who have learned how to think and how to problem-solve.  With the adoption of Common Core State Standards (CCSS) and the Next Generation Science Standards (NGSS), we are getting closer to making that a reality, but so many states and districts are still focused on standardized testing (which- surprise-  did not make the list of qualities that employers are looking for in qualified candidates.)

This series focuses on those skills as well as the other "soft-skills" that aren't necessarily spelled our in the curriculum, but make students well-rounded problem solvers.

This week's challenge is the Gumdrop Bridge.  In  this challenge, students work in teams to design and build a bridge that will span 10 inches.  Sounds like a pretty easy challenge, but as students start experimenting with their materials of gum drops and toothpicks, they will find that there is more there than beats the eye.

This fun little challenge encourages students to work on team building, collaboration and communication skills- more of those soft skills- that help students become successful in a workplace environment.

The Brown Bag STEM Challenge II- Marble Madness

Students are used to challenges that ask them to do something the fastest, but how about the slowest?  In this scenario, students are challenged to create a marble run where the marble that reaches the end in the slowest time wins.

Materials
Marbles
Bathroom Cups (3 oz)
Sentence Strips
Foam Board (20x30)
Tape
Other Found Objects

This challenge is a great way to get kids thinking more deeply because the challenge is to complete the course the slowest.  Each team must create a course for their marble using piece of 20 x 30 foam board.  Students can use any found items that you provide, but I like to make sure to include sentence strips because they are thicker than regular paper and can easily be folded into marble tracks. I also like to provide some fun items like bathroom cups, cotton balls, cardboard tubes and paperclips to make creating the course more fun.

So, what did we learn?

STEM Skills Challenge Series

What if STEM stood for something different? As you know, the actual acronym stands for Science, Technology, Engineering, Math, but aside from content, the concept encompasses many more essential skills like: problem solving, critical thinking, team-building, self-esteem, self-motivation and more.

At a recent symposium in the Seattle area, business leaders were surveyed regarding the skills, attitudes, attributes, and aspirations that they feel are the most important to the success of students in the future. Among the results?
  • Critical thinking, learning, and analytical problem solving
  • Communication
  • Adaptability
  • Collaboration and teamwork
  • Self-direction and self-awareness
  • Technical skills and computer literacy
  • Fundamentals of education including math, science, and English
  • Creativity
  • Cultural competence and global awareness
  • Emotional intelligence
This series on STEM Skills Challenges will harness the power of STEM challenges and focus on these essential success skills that our students need to be effective in the STEM workforce.
