Bromfield Science Fair 2015

This is Melissa Mazzu with a project on pH and Tomato Plants - she's holding a tomato plant that was 'watered' with only Market Basket Lemon Juice -- it grew the best (the lemon juice had a pH of around 4)

Harvad Conservation Trust judge Kim Manning listens as Chloe Fitzgibbons explains her project, “Best Bird Feeder,” in which she studied feeder type preferences of several bird species.

Judge Nick Browse takes a break to score a project.

Meredith Greayer shows off two of her control plants. The plants used in ther experiment, “The Effects of Different Types of Ice Melt on Plant Health,” did not fare nearly as well.
