This classic and super easy fundraising idea uses nature to determine the winner. The basic concept of the breaking temps fundraiser is that you have people guess which day the temperature will hit a pre-determined degree mark. The person who guesses the correct day is the winner.
You can do this fundraiser in the summer (which day will break the 100 degree mark), or in the winter (which day will break the 10 degree mark). Obviously, you can set your temperature goal to whatever you want and whatever is appropriate for your area. This fundraising idea works great for any size club, group or organization.
You will need to start requesting submissions about 3 months prior to the time period you would expect to have a winner. If you have a lot of participants, expect multiple winners. Ask your local media outlets for help with publicity. Request donations for participation or ask local businesses to sponsor.
Add an entry form to your website where people can fill out their contact info and select the day the temperature will break your set mark. Be sure to promote heavily on all your social media channels. Also, create some fun and creative posters and flyers that you can place throughout the community.
