Anatomy & Physiology

Can you go with the flow? Show your knowledge of the Cardiovascular, Lymphatic, and Excretory systems.


Become a star by providing explosive answers to problems on stellar evolution in normal and starburst galaxies.


Design, construct ahead, and test a lightweight cantilever beam to support 15 kg.

Chemistry Lab

Solve lab problems using your science process skills in physical properties and acids and Bases.

Circuit Lab

Are you in the resistance? Design and construct simple circuits for a designated task; answer written questions on electricity and magnestism.

Code Busters

Become Fargo North, Decoder! Decode encrypted messages using cryptanalysis techniques and show skills with advanced ciphers by encrypting or decrypting a message.

Designer Genes

Solve problems and analyze date or diagrams using your knowledge of classical and molecular genetics and biotechnology.

Disease Detectives

Don't speak ill of people. Solve problems in disease, injury, or disability in human populations.

Dynamic Planet 

Are you cold as ice or are you hot? Solve problems related to glaciers and climate change.

Experimental Design (up to 3 students)

Given a kit of materials you must design, conduct, and report an experiment on-site.

Fermi Questions

Come up with fast, rough estimates of quantities that cannot be measured directly.


CSI Connecticut! Analyze evidence from a crime scene and identify the guilty person.


Demonstrate your knowledge of ancient life by completing tasks related to fossil identification and classifications. Use fossils to date and correlate rock units.

Geologic Mapping

Are you in the underground? Solve problems using cross sections, topographic and geologic maps. Form interpretations of subsurface structures and geohazard risks in subduction zones.


Slither your way through identification and questions on amphibians and reptiles.

Mission Possible

Design, construct ahead, calibrate, and document a Rube Goldberg device incorporating a series of steps that result in the device saying "the end".

Mousetrap Vehicle

Design, construct ahead, calibrate and document a vehicle powered by mousetraps to push a plastic cup forward to a target leave it, then reverse to its own target point.

Protein Modeling

Three parts: 1. Use home computer visualization to construct ahead a physical model of the CRISPR Cas9 protein. 2. Use on-site computer visualization to construct a protein model using provided materials. 3. Answer questions about protein structure.

Sounds of Music

Design, construct ahead, and test one device based on a 12-tone equal tempered scale. Complete a written test on the physics of sound.


Some like it hot! Design and construct ahead and test an insulated device to keep a glass of hot water hot. Answer written questions on thermodynamic concepts.

Water Quality

Design, construct ahead, and test a salinometer. Identify aquatic invertebrates and answer questions on fresh water ecology.

Write it, Do It ( 2 students required)

Don't have a failure to communicate! One student sees and describes a device; another uses that description to build the device from a parts bag.
Please note: For any event requiring students to build a device ahead of time- The students themselves must construct all devices. Coaches or parents can help with safety issue like running table saws, etc. Students must be able to demonstrate to judges that they have done the design and construction of a project. During competition, students are not allowed any outside help from parents, coaches, or spectators. 
If an event has both a constructions portion and a written test, students must try both parts to be fully participating.
