Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Best Bubbles
Source Institutions
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
Draft Detectives
Source Institutions
In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.
Exploring Materials: Liquid Crystals
Source Institutions
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Surface Tension Icebreaker
Source Institutions
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Jem's Pykrete Challenge
Source Institutions
In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Rubber Band Thermodynamics
Source Institutions
In this demonstration, learners explore the thermal properties of rubber. Learners investigate whether a rubber band contracts or expands when heated.
Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.
What Smart Metal!
Source Institutions
In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Get It Write
Source Institutions
In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.
Submarine: Soda Cup Lander
Source Institutions
In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.
Exploring the Nanoworld with LEGO Bricks: Probing the Structure of Materials at the Nanoscale
Source Institutions
In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.
