Assessing Students – STEM Projects

STEM Exit Ticket

STEM projects are GREAT…but it’s hard to track how much my students are really learning!!

So here’s my solution:
1. Exit Ticket Assessment
2. Grading Rubric
3. Student Score Chart

The Exit Ticket contains four basic questions that can go with almost any STEM lab. The answers to these questions will help you assess your students’ level of involvement and understanding of the concepts addressed. It also gives an idea of which labs are effective and which are not and maybe what could be done different next time.

The Grading Rubric gives a common standard to score these assessments on. It makes grading a ton easier.

The Student Score Chart helps keep all that data organized!!

You can check it out here, in my TpT Store! It’s only a dollar…like something awesome on the shelf at Dollar Tree…only it’s way better and you don’t have to drive…just click the link below!!

Have a great time with STEM!!


Jumping Bugs Activity!!


We are having abnormally awesome weather for February here in the Midwest United States. I took advantage of this nice weather to have some science fun outside with my kids! What could be more fun than watching bugs jump?

Here is the list of activities you will need, materials listed below are per group (3-4 students):

• 2-3 film canisters with lids (either 1 per student or 1 per group). I buy these on ebay • Tape (scotch or masking)
• 2-3 scissors
• Beaker or cup with water in it
• 2-4 “Alka-seltzer” tablets (meaning 1-2 packets)…. (I don’t buy the name brand tablets)
• markers, crayons or colored pencils
• 1 Meter stick (for you the teacher to use)
• “Bugs sheet” pdf (pre-cut)
• Student instructions Sheet
* A few towels to help clean up the area when finished*


In this video I explain how to run the activity and explain the science behind it.

First, my kids colored and cut out their bugs! This is a chance to make it a “STEAM” activity. They loved this part. They folded along the dotted line and taped it to the bottom of the film canister. Some younger children will need help with that part.


Next you pour water into the film canister and add the tablet.


Close it up and place it with the cap down. You’ll need to do do this pretty quickly!! Again, the younger kids will need help with this.


Wait for it…wait for it…and then…POP!!!


Kids can use their worksheets to follow along with the instructions, record data and improve their results. This worksheet, materials list, teacher instructions sheet and grading rubric and teacher instruction video are available in a single pdf file FOR FREE in my TpT store. Here’s the link:


Try it with your students and let me know how they do! Thanks for visiting my blog and reading this post 🙂 STEM is always a great to engage and bring learning to life!

STEM Career Spotlight: Software Developer

software developer STEM

Question #1: How much will I make?? The median salary for this job is $100,690 per year!

Problem Solving! It seems that every STEM job requires a good deal of problem solving ability. A Software Developer career is no exception! They analyze what users need, create solutions and continue to improve and redesign, especially when problems come about in the design process!! People in this profession also need to be able to communicate clearly and think creatively.

“A software developer is a person concerned with facets of the software development process, including the research, design, programming, and testing of computer software.” -Wikipedia

When you’re programming and testing computer software, it is super important to be detail oriented as well. Multi-tasking is a huge part of this job and they need to be able to focus on a number of details all at once.

To become a software engineer you need a solid education—usually a bachelor’s degree in either computer science or math. It’s also important to have some sort of internship during college.

What I Wish I Knew When I Started My Career as a Software Developer


United States Bureau of Labor

Occupational Outlood Handbook



STEAM is the combination of Science, Technology, Engineering and Math with ART. When I first heard about adding the art component to STEM, I thought, “seriously, what does art have to do with it?”.  Are we just trying to be “politically correct” by including art so it doesn’t feel “left out”? I know that sounds barbaric, but being truly honest, that’s really what first came to my mind.

After sifting through several articles…including art is, indeed, a great idea. It draws out those awesomely creative right-brained kids out of their apprehension towards science and math. These kids are invaluable in the STEM fields—they are innovators and creators, dreamers who think up amazing ideas and plans.

With a little inspiration, these kids can go on to become the next Leonardo Da Vinci or Steve Jobs. Da Vinci combined art and science. He “believed art, was indisputably connected with science and nature”* and came up with extremely unique and innovative ideas. Steve Jobs seriously tapped in to that “Right” side of his brain, working with left-brained colleagues (most prominently, co-founder, Steve Wozniak) to visualize and market some of the most influential devices of our day (ever heard of the “iphone”?).

My point is, Steve Jobs wasn’t involved in the actual developing of products—he wasn’t a programmer or software developer—he didn’t know much about technology—BUT he knew how to work WITH people who were developers and tech genius’s. We need to teach right and left brain kids the skill of working together!

Involving the “artsy” kids in STEM brings a whole different dimension to not only what THEY can become, but also the mark they can leave on our world.
