Instant Ice
Source Institutions
In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.
Science of Sunblock
Source Institutions
This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl
Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
Colorful Electrophoresis
Source Institutions
In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.
Seas in Motion
Source Institutions
In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.
Optical Morpher
Source Institutions
In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.
Temperature vs. Height: Soda Geyser Series #6
Source Institutions
In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.
Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.
Half Full or Half Empty
Source Institutions
In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.
No-Slip Grip
Source Institutions
In this physical sciences activity, learners explore friction. Learners investigate the factors that affect the force required to move an object.
Wandering Wands
Source Institutions
In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.
Dispenser Designs
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.
Hoop Glider
Source Institutions
In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.
Temperature Tactics
Source Institutions
In this activity, learners explore the devices used over time to measure changes in temperature.
Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
Piezoelectric One-Way Remote
Source Institutions
In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.
Balancing Act
Source Institutions
In this activity, learners will explore their center of gravity.
A Question of Balance
Source Institutions
In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.
Drawing Board
Source Institutions
The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.
Can You Copperplate?
Source Institutions
In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.
