Help change the world

It costs a lot to bring high-quality CaveSim education to kids around the United States. Many schools need help affording our programs, and some cannot pay anything to have CaveSim come to their campus. It also costs a lot to produce our high-quality online educational content, and we need your help launching our second mobile cave project.

When you make a purchase on this page, you get to specify what we use the funds for. In case you’re curious about the needs that we have, there’s a wish list below.

Our wish list:

Funds to support schools that need help affording CaveSim programs.
Replacement pulleys for the CaveSim tower. Approximate cost: $150 for 5 pulleys.
Diesel pickup truck for transporting the new mobile cave. This will allow us to use both the old cave and the new cave simultaneously with two teams of educators. Approximate cost: $30,000. Current progress toward goal: $0
Honda 2200 watt generator for running CaveSim at remote locations like state parks that don't have available power. Cost: $1099.

Make a tax-deductible contribution to the Cave Research Foundation
We understand that tax considerations are an important part of charitable giving. That's why we've partnered with the Cave Research Foundation (CRF), which has a special fund specifically for supporting CaveSim programs at schools that need financial assistance. Nearly all of your donation goes right to supporting these schools in need (CRF does take a small amount - 1% or less - to pay for web hosting, insurance, and other organizational costs).
There are several easy ways to support CaveSim through CRF:

1) Checks can be mailed to:
CRF Treasurer
6304 Kaybro St.
Laurel, MD 20707

2) If you prefer PayPal, visit the CRF site to make a payment. Be sure to select "Education outreach fund (CaveSim)."

3) If you would like to give through your employer or financial institution (such as Fidelity), you can connect with the CRF treasurer via the form below. Setup is quick and easy.
