NEW HAVEN, Conn. (WTNH) — From the life cycle of a snowman, to the warming of the earth, New Haven public school students are heating up with science.

The 21st annual New Haven Science Fair showcased 235 projects from public school students. The two-day event, which kicked off Tuesday, filled the Yale Commons at Woolsey Hall. Nearly 7,600 students submitted work, ranging from three-year-olds in Pre-K up through 12th graders. Projects feature current events, health, technology, and the environment, to name a few.

Seventy mentors worked with the students. One-hundred seventy judges from around the community evaluate the projects.

We saw so many excited kids who were clearly proud of their projects waving at our camera. Check out the video below to see if your kid make the clip.
