3D model of LTBN results using LEGO blocks3D Model on Display at Bittersweet

Students built a model of the results of the Let There Be Night experiment using over 35,000 LEGO blocks to represent the ideal night sky. From that 3D map, over 12,000 blocks had to be removed to represent the night sky lost to light pollution, according to over 3,400 student observations. The 3D model is displayed at Bittersweet Elementary School, right, November 9-13, 2009.

Bittersweet Team Student Team Takes on Roles

Students representing Bittersweet have been meeting at the PHM Planetarium to prepare for the community-wide experiment. Here they are shown in front of a poster announcing Let There Be Night. They have several roles, including coordinating the LEGO drive, addressing Earth Hour, and measuring the sky glow from school grounds with hand-held Sky Quality Meters (SQMs).


Orion at the Entrance

Bittersweet Elementary School students designed their own images of Orion from the stars of the constellation. The student art shown here was on display in the front entrance.

Punchout of Orion

Teacher Jenny McCarthy has been very supportive of Let There Be Night. She designed a punchout of Orion for an overhead projector (the less expernsive kind) and shared her idea with Mr. Klinger. She then enlisted the support of Bittersweet parents, who made copies of the punchout for each of 11 PHM elementary schools.

The drawings by the kids show there are different ways of seeing things--like Galileo with his improved telescope. But first we have to look up.

Here are links to some great drawings by kids depicting Orion, with more images at

Bittersweet School Teacher In-ServiceTeachers Prepare

The support of teachers is paramount to the success of this community-wide science experiment. Bittersweet teachers prepared for Let There Be Night on September 29, 2008, at the first of two in-service meetings. Here, teacher Jenny McCarthy introduces the Orion punchout and other optional activities to her colleagues
