Science Expo

Imagine a day where bees, lasers, horseshoe crabs, bubbles, chickens, rainbows, and beetles descend upon the school. Or perhaps you hear a loud chemistry explosion, see marshmallow peeps expand, or witness a sorting dance while words like "photosynthesis," "central limit theorem," and "bionic eye" come drifting into the halls.

This is the LB Science Expo, a day where science truly comes alive at Littlebrook. This year, on Thursday May 18, talented scientists, parents and community members will volunteer their time to wow our children for the 8th annual Science Expo.  

Please follow the links to learn more:

Many Thanks to all of the Generous Participants!

This event would not be possible without an army of volunteers! As in years past, we will need many to help the day run smoothly.  If you would like to join us in supporting the Expo, please sign up here or email Molly Jones ( Thanks!

Also, many thanks to all of last year's volunteers. We must also continuously thank Martha Friend, LB's Science Teacher, for her unwavering support and encouragement of this event each and every year.  


The LB Science Expo needs scientists, biologists, mathematicians, engineers, physicians, astronomers, chemists, geneticists, and more, as well as those who have a scientific hobby or passion to contribute! Share an activity, presentation, or simply your knowledge and enthusiasm about math or science with our students. 
Here are a few facts about how the Expo works:
  • During the Expo, students rotate from one classroom to another every 20 minutes.
  • As a presenter, you will be assigned to one classroom, and a new class will arrive to see your presentation every 20 minutes.
  • Thus, in one hour, you can present to 3 classes, and you are welcome to tell us how much time you can be available.
  • Some presenters come in the morning, others in the afternoon, and still others stay all day!
  • You are welcome to present to your children's grades, and/or any others that you feel will be appropriate for your topic. For example, some presenters target younger children (K-2) and others target older ones (3-5), whereas a few presenters can even take on a wider range.
  • Littlebrook Science Educator Martha Friend can help adjust your activity to make it appropriate to various grade levels.
  • Do you have any other questions? Please email Jenny (
  • Otherwise, to register to be a presenter, you just need to complete the following form.
