How to do a Lego Engineering Project for Second Grade

Here's a beginner Lego engineering project that's fun enough to do at home, and aligned to NGSS standards for school.

"That's so cool. I have to tell Mom!" Over hearing that phrase makes any winter break project a winner on its own, but this LEGO engineering project was also super easy and covers NGSS standard k-2ETS1-2

"Develop a simple sketch, drawing, or physical model to illustrate how the shape of an objec helps it function as needed to solve a given problem."

To do this Lego Engineering project you will need

About 20 Legos
rubber bands 
other office supplies (optional)
cotton ball (optional)

Disclaimer: Always be sure to monitor flying objects to prevent injury.  Fast  moving Legos could hurt someone.

Step 1 of your Lego engineering project

  Tell your students to build a sling shot that launches a single Lego, or if you want to be a little safer in a large group, a cotton ball.

You could really assign any LEGO contraption, but sling shots are fun. Check out our launcher.

Step 2 of your Lego Engineering Project

Ask your students to, "draw a picture that explains how their Lego launcher works, and label every important part."

Here's a beginner Lego engineering project that's fun enough to do at home, and aligned to NGSS standards for school.

That's it. You're done! However, your students may need a little longer to play, like my child did.  I just hope he always wants to tell me about it.

  1. What a fun LEGO engineering activity!

  2. We are sooo building LEGO Launchers this weekend!! Thanks for this awesome idea!!!

  3. My son is a bit young for this but I LOVE IT! It is so simple but a great way to start learning how to record observation.

  4. So fun! My son would love the Lego launcher!

  5. What an awesome engineering project. I love the video. Pinned!

  6. That sounds like fun! Launching anything is usually a hit around here! :)


I can't wait to hear what you have to say! Thanks for sharing.
