Anatomy & Physiology

Do you have skin in the game? Show your knowledge of the integumentary, Skeletal, and Muscular systems.


Develop into a star by showing your understanding of star and galaxy formation and evolution.


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

Chemistry Lab

Solve lab problems using your science process skills in aqueous solutions 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 (Up to 3 students)

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.

Detector Building

Design and build ahead, and test a digital electronic detector to measure water temperature.

Disease Detectives

Are you well? Solve problems in disease, injury, or disability in human populations.

Dynamic Planet 

Dive deep and solve problems in physical and geological oceanography.

Experimental Design (up to 3 students)

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


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, classification, adaptations and ecosystems. Use fossils to date and correlate rock units.

Geologic Mapping

Show your skills in using and drawing topographic maps and cross sections, and use them in interpreting subsurface structures and past environments.

Gravity Vehicle

Design, build ahead, calibrate, and test a vehicle launched from a ramp to reach a target as quickly and accurately as possible.


Design, build ahead, calibrate, and test a lever-based compound machine to determine the ratio between two masses.


Will you be able to crow about having the best knowledge of bird identification, anatomy, physiology and ecology?

Ping Pong Parachute

Design, build ahead, calibrate, and test two air-powered bottle rockets, to be launched indoors, that will deploy a ping pong ball with an attached parachute for maximumn time aloft.

Protein Modeling (Up to 3 students)

Three parts: 1. Use home computer visualization to construct ahead a physical model of the cytidine deaminase 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 two octace 12-tone equal tempered scale. Complete a written test on the physics of sound and music concepts.

Water Quality

Design, construct ahead, and test a salinometer. Identify aquatic invertebrates and answer questions on marine and estuary aquatic environments.

Wright Stuff

Let your dreams take flight! Design, construct, document, and test up to two rubber powered airplanes for maximum indoor flight time.

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.
