What We Do

Engaging Contests

Download our activities to conduct with your students and upload the results to compare your class\’s scores to the scores of classes globally.

Aligned Content

Our activities include pertinent supplemental curriculum material that is aligned to National Standards.

Emphasis on Team

Your assessment scores are greatly affected by how well the team members work together, instilling in your students the value of teamwork.

Where We Are

STEM Playground began as a small pilot program for 10 schools but has grown over 500% in the last two years.

Students will investigate how to slow an object’s speed as it travels down a ramp.

Bounce the Light

Students will bounce light off of mirrors to hit a target.

Tennis Ball Tower

Students teams will all use the same materials to build a tower that is both tall and strong.

Students will build and test a hovercraft.

Spelling Bee of Science

Students will better learn science vocabulary words, including their spelling.

Students will design and build a bridge that can hold a cup of marbles without breaking or collapsing.

Teams will design, build, and test a boat.

Follow the Leader!

Each team will have a “Leader” and a “Follower.” The Leaders will examine a paper airplane and write a set of directions for constructing it. The Followers will follow the written instructions to reconstruct the object.

Soaring the Solar System

Teams will successfully identify and label as many solar system-based objects as possible in a 15-minute time frame.

Teams will successfully identify and label as many organelles in an animal cell as possible in a 15-minute time frame.

Teams will construct a rubber band-powered catapult and launch different-sized marshmallows at a stationary target.

Let's Get Elemental

Teams will successfully identify and label as many elements from the Periodic Table as possible within a 15-minute time frame.

Northrop Grumman Aircraft

Teams will construct a paper plane and then test it for distance.

The Sky is Falling

Teams will have 20 minutes to design and construct a parachute that will slow the descent of a golf ball as much as possible when dropped from a pre-determined height.

Teams will design and build paper darts and then test the darts by launching them from drinking straws.

School of Rocks

Teams will successfully identify and label as many rocks as possible within a 15-minute time frame.

Cloudy With a Chance of Science

Teams will successfully identify and label as many types of clouds as possible in a 15-minute time frame.

How We Align to Standards

STEM Playground designed its STEM activities and supporting curriculum material around you and your students, NOT Common Core standards. However, we understand the need for those of you in Common Core-participating states to meet English Language Arts and Math standards, even as you teach science.

So STEM Playground asked educational publisher Longbourn Editorial to correlate our current curriculum material to both Common Core and Next Generation Science Standards.

How Our Competition Works

STEM Playground\’s activities are designed to be completed by teams of two students and will have measurable results which you can compare with other classes globally, nationally, or even within your own community or school.

While you can compare results from just one activity, you can also compete in the cumulative League Challenge by completing all 12 designated League Challenge activities.
