How fast do tulips grow? This is the question students in Salem, New Hampshire have investigated for several springs. Roller coaster temperatures in the spring gives them the opportunity to collect some interesting data.

“Our tulips grew 2 cm per day during 70°F temps, but they grew less than 1 cm per day when the snow was on the ground. The past few days have been close to 70°F and we have bloom! We’ve learned a lot about how abiotic factors like temperature and precipitation impact living things like our Red Emperors. Thanks to Journey North, we have a great investigation that helps make our school look great too!” - 2017, Mark Huebner
