Sea Level: On The Rise
Source Institutions
Learners will understand the relationship between climate change and sea-level rise.

Electrolysis
Source Institutions
Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

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.

Four of the States of Matter
Source Institutions
This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

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.

Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Currently Working
Source Institutions
Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.

Surface Area
Source Institutions
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
