Community Earth Day Scavenger Hunt

Event Overview

This year we are celebrating Earth Day (April 22) with a weeklong Community Scavenger Hunt! The event will kick off on Saturday, April 17, with the City of Broomfield’s Earth Day celebration at the public library. Throughout each day, registered participants will see 8 or more challenges appear on the free GooseChase app on their smartphones. Each challenge will ask the participant to search online to answer a question, take a photo of themselves completing an activity, or visit different areas of Broomfield.

All challenge responses will be submitted through the GooseChase app and those completed successfully will earn the participant valuable points! Throughout the week and at the end of the game, prizes will be awarded to those participants with the highest point totals. There may also be bonus challenges to earn prizes and some random drawings. The Scavenger Hunt will conclude on Sunday, April 25, with the final challenge, a full moon bike ride through Broomfield’s open space with your family. This community game is perfect for people of all ages and ability levels and is a great way to explore Broomfield, get outside, learn something new, and support your community!

Event Details

Getting started

Read about the Community Earth Day Scavenger Hunt between April 3rd and April 14th at Register for a game starting 6am on Wednesday April 14th. You may join anytime! The game challenges will launch on Saturday, April 17 and run through Sunday, April 25th, so register before April 17th to play all week!

The link above accesses the Scavenger Hunt instructions, game rules, details, and prize information. The instructions will direct you to download the free GooseChase app to your smartphone and register by either creating a GooseChase account or opt to play as a guest. Participants may join as an individual (13 and older) or a family.

Next you will choose and enter a game code, which are provided at the bottom of the instruction page. We offer different game codes so different groups of people (like neighbors) could all play in the same game. A single game can have up to 40 participants, but all games will offer the same questions at the same times. Once you have chosen your game, create or select a player profile and you are ready to begin!

Playing the Game

All challenges that appear in GooseChase will contain the instructions you need to follow to earn points. The challenges will help you learn about Earth Day topics and help you explore Broomfield! Stay tuned to GooseChase as you never know when the next challenge will pop up.  Some challenges may even have time limits on them, while many will last all week. You can even earn extra points for impressing the judges behind the scenes so be creative, appropriate, and have fun with your posts!  Of course, you could also lose points if they aren’t pleased with your efforts. Join us for some online fun! 

Safety is a priority, so please be safe while participating, practice social distancing, and have fun in a positive way! Negative posts will not be tolerated and participants will unfortunately be removed if they appear. Please keep the game fun and family friendly! 


Prizes will be awarded to top point earners across all games (participants will be competing within their game but also against other people in other games). To collect your prize you will have to complete a form with a link launched INSIDE GooseChase during the week. Prizes will be distributed after the game has concluded. A full list of prizes to come.
