In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Tabloid Science
Source Institutions
In this activity, learners analyze a fictionalized report of life on Mars, based on a real NASA satellite photo, and explore how to separate scientific fact from fiction.
Crayfish Investigations
Source Institutions
This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.
Fish Wheels
Source Institutions
In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur
Edible Glass
Source Institutions
In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).
Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
