The Science Carnival and Robot Zoo was held on Saturday, April 15th, 2017. It is the largest event of the Cambridge Science Festival, with over 15,000 visitors. Twelve of our 4th, 5th, & 6th Graders were happy to be among the participants! Birches students did a remarkable job explaining their sleep research project and presenting their carefully designed posters to visitors who stopped by our table. Ours was the largest group of elementary school students presenting at the Festival. Many young scientists do not get the opportunity to present posters at a fair like this until they are in high school or college.
