Inspiring Future Women in Science — live Q&A

On Thursday, February 11, 2021, a dynamic group of four women working in various fields of science took students’ questions in a live online session. The program was designed for high school students who are interested in science and want to learn more about careers in related fields. Although this event was part of Perimeter Institute’s International Day of Women and Girls in Science activities, high school students of all genders were welcome to participate. Watch the 60-minute session.

Jessica Schaub

Jessica Schaub
Master of Science Student in Oceanography,
University of British Columbia

Education: HBSc Oceanography & Biology,
University of British Columbia

Jessica grew up in rural northern Alberta but has always been drawn to ocean sciences. After graduating high school, 17-year old Jessica made the difficult decision to move to Vancouver after being accepted to the University of British Columbia. Navigating academia as a first-generation university student was challenging, but incredibly rewarding. Jessica graduated with a combined honors degree in Oceanography and Biology in 2018 and developed a passion for jellyfish research. Now as a graduate student, Jessica is dedicated to addressing barriers for under-represented groups in academia, including women and Indigenous peoples. Her outreach is directed by the challenges she experienced as an undergraduate student in the hopes that she can improve experiences for future students.

Perimeter Institute seeks to involve a diverse group of STEM mentors in this annual event supporting the UN's International Day of Women and Girls in Science. If you are interested in sharing your story at a future event, please contact us at [email protected].

What is it like to be a woman in physics?

Perimeter students, researchers, and staff share their experiences in celebration of the International Day of Women and Girls in Science. Read their stories here.

Forces of nature poster series

Illustration of portraits of women's faces

Women have been historically under-represented in physics; progress is happening, but there is much work to be done. Part of making positive change includes celebrating the contributions women have made to science, especially those women overlooked in their time.

That’s why Perimeter Institute has created the free “Forces of Nature” poster series. In February 2021, the collection grew with the addition of Rosalind Franklin, Bibha Chowdhuri, and Hedy Lamarr. Download your posters here!

Escape the forces of nature museum

Collage of illustrations of famous women's faces

In this free online escape room activity, you are accidentally locked in the Forces of Nature Museum after it closes, and will need to solve a series of challenges to escape! The puzzles require logic and creativity; advanced mathematical skills are not required but the youngest members of your household might prefer these colouring pages instead. When you escape you’ll unlock new Forces of Nature posters. Begin your adventure here.
