Dear (recipient's name),
Thank you so much for your generous donation to my fundraising campaign supporting Science-A-Thon 2019!
Your contribution to this year's partner charities makes a huge difference for girls and women pursuing careers in science, technology, engineering, and math (STEM!). The Earth Science Women's Network, Girls Who Code, and the Society of Women Engineers use this money to profile women in science, provide critical infrastructure, support skills workshops, expand job-finding resources, and encourage college students to pursue STEM.
By donating to these amazing organizations, you are making science a better place for all and helping early career scientists in many ways.
