Elementary Science Olympiad (ESO) is the perfect complement to any K-6 science program. Support your normal classroom routine with an all-building Science Olympiad Fun Day, or bring in experts and parent volunteers to run a Science Olympiad Fun Night. If you want to develop a feeder program for your district’s middle school Science Olympiad program, run a grades 3-6 competitive tournament, just like the older kids, and with many of the same events, just scaled down to size!

Elementary Science Olympiad events take advantage of the natural curiosity of each child, and allow for in-depth hands-on experiences.  These programs are designed to utilize ordinary classroom and household supplies and materials, so your ESO event won’t break the bank!

ESO content is so wide-ranging that we encourage use in places outside of school — such as park districts, libraries, nature centers and bookstores. Set up a Science Olympiad “Don’t Bug Me” Day at the playground, catching insects and cataloging your finds. Have parent architects and engineers explain structural science with a Straw Tower Challenge. Or get a bunch of books about animals out at the library and host a big game of Science Olympiad concentration, matching stuffed animals to their scientific names or habitats. Have fun with it!  We’ve even had requests to use our ESO content for birthday parties, and we say – go for it!  Science is everywhere, and young children are fascinated by the way things work. Roll up your sleeves, crack open an ESO manual, and start planning!



2019 (Division A) Elementary Events

Circuit Wizardry – This event will challenge the pupil’s knowledge of direct current (DC) circuits using low voltage batteries. Wall socket (AC) current will not be used!

Disease Detectives – The goal of the Disease Detectives event is to have pupil’s understand connections between things they may encounter in daily life and various health problems that affect communities, risks for disease/injury, and opportunities for prevention.  The event will also help pupils to understand general categories of causes of diseases and injuries.

Elements, Compounds, Mixtures – The objective is to test the ability of the pupils to classify materials into one of the three categories.

Mystery Architecture – This event is designed to test the pupil’s ability to think on their feet.  They will be given a bag of materials to build a freestanding tower as high as they can.  The tower would be constructed to support a weight (e.g tennis ball) at its top.

Mystery Powder – A team of two contestants will be asked to identify a mixture of common white household powders.


B/C Events

Science Olympiad employs cross-cutting concepts in all of its standards-aligned events, building 21st century skill sets essential to today’s science, technology, engineering and math (STEM) workforce. There are 18 events each in Division B (JSSl) and Division C (SSS), providing a platform for students to apply and display a wide variety of talents, from design and prototyping, to technical writing, to chemistry lab skills. A team of 12 students pairs up to tackle the 18 events which are generally spaced in six 50-minute blocks across a Saturday/weekday, encouraging collaboration, teamwork and cross-training

Anatomy and Physiology

Understand the anatomy of the human body systems: cardiovascular, lymphatic and excretory.

Battery Buggy

Teams will construct a vehicle that uses electrical energy as its sole means of propulsion, quickly travels a specified distance, and stops as close as possible to the Target Point.


Teams will design and build a Boomilever meeting requirements specified in the rules supporting a minimum load and to achieve the highest structural efficiency.

Disease Detectives

Participants will use investigative skills in the scientific study of disease, injury, health and disability in populations or groups of people.

Dynamic Planet

Students will use process skills to complete tasks related to glaciers, glaciation and long-term climate change.

Road Scholar

Participants will answer interpretive questions that may use one or more state highway maps, USGS topographic maps, Internet-generated maps, a road atlas or satellite/aerial images.

Solar System

Students will demonstrate an understanding and knowledge of the geologic characteristics and evolution of the Earth’s moon and other rocky bodies of the solar system.

Write It Do It

One student will write a description of an object and how to build it, and then the other student will attempt to construct the object from this description.
