Beacon Street Girls, Book 13: Green Algae and Bubblegum Wars

Meet the Beacon Street Girls...They're real, they're fun-they're just like you!

Science isn't exactly Maeve's favorite subject, but she's still excited to be going to the Sally Ride Science Festival at MIT with her hunky tutor, Matt. Sure, the BSG and her annoyingly brilliant younger brother are going as well, but it's still almost kind of a date, isn't it?

The festival gives the BSG a super idea-an environmental science fair at Abigail Adams Junior High. But plans for a bubble gum factory nearby put Avery and Katani on opposite sides of an environmental issue-and Avery finds herself in a bubble gum war with the Queens of Mean!
