Density and the Ocean

Overview

ESR has developed a fun, engaging, hands-on exhibit that explains density and its importance in the ocean.

The exhibit has been designed to be used at elementary and middle school (1rst – 8th grade) science fairs, STEM events, and festivals.

Equipment and personnel time is supported by ESR and the National Science Foundation (NSF).

ESR is committed to providing outreach to our community in a variety of ways, from adult lectures to school talks and STEM events. For more information, contact our Outreach Coordinator, Susan Howard.

Density & the Ocean Exhibit

Exhibit Description

ESR’s exhibit focuses on the concept of density and the ocean by providing several hands-on activities which explore the properties of density. Participants get to:

  • Compare objects of the same volume but different weight.
  • Play the “Sink or Float” guessing game: compares the density of solid objects to water using an aquarium.
  • Observe the different densities of liquids in a density tower.
  • Experiment with cold/salty water and warm/fresh water using beakers, colored water and pipettes to see the density differences.
  • Discuss how density is important in the ocean.

Event List

ESR first started participating in outreach events with this exhibit in 2013. Since then, requests for our participation has grown through word of mouth. A School event usually draw 200 – 300 hundred people. Large festivals have drawn more than 600 -700 people. We look forward to continuing our participation in local community events.
