In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

In this activity, young learners use their sense of touch rather than sight to identify a mystery object in a bag. Learners take turns acting as "peekers" and "sensers" throughout the game.

In this activity, learners use what they know about probability to figure out what is in a mystery bag. Learners analyze data to guess how many of each color crayons are in the bag.

In this outdoor activity that can be combined with a hike, learners try to match a "mystery community" by shaking animals out of different trees and shrubs.
