Go with the Flow
Source Institutions
Learners draw comic-style pictures to show the water cycle. From a starting picture, one learner draws what happens to the water in the next panel, then passes the comic strip to another learner.

Chromatography Observations
Source Institutions
In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.
The Right Fit
Source Institutions
In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

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.

Cranking Bird
Source Institutions
In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

Momentos de Mixing in Math: Varias Actividades Matemáticas de 5 ó 10 Minutos
Source Institutions
Los Momentos de Mixing in Math son actividades de 5 a 10 minutos que mantienen a los chicos ocupados, aprendiendo sobre el mundo, y usando matemáticas por su cuenta.

Design a Fish
Source Institutions
In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

Constellation Chamber
Source Institutions
Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

Mirror, Mirror
Source Institutions
In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.
Build a Bridge
Source Institutions
In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

Go Fly a Kite
Source Institutions
In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

Binary Code Bracelets
Source Institutions
In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

Metallophone
Source Institutions
In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

Crystal Packin' Mama
Source Institutions
In this activity, learners investigate the basic crystal structures that metal atoms form.

Make a Friend from Soil and Seeds
Source Institutions
Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.

Spinning Tops
Source Institutions
Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

Liquid Lava Layers
Source Institutions
In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.
Mystery Jars: Make Your Own: Estimating and Counting
Source Institutions
Learners make a counting/estimating jar to exchange with friends or bring home.

Coral Polyp
Source Institutions
In this activity, learners will create their own coral polyps - the basis for a coral reef.
