Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

Convection Demonstration
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

Floating and Falling Flows
Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.
