As learners play this challenging strategy game, they build understanding of area and perimeter. On each turn, a player draws a line between two dots next to each other on the grid.

This strategy game has simple rules but can be a challenge. Players start with an empty hexagonal grid. On each turn, a player initials one empty hexagon on the grid.

As learners play this game, they develop logic, geometry, and spatial visualization skills. Players start out with an empty hexagonal grid.

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

In this activity, learners use tangrams ( 7-piece puzzle tiles) to assemble a variety of shapes. Tangrams are ideal for improving spatial reasoning and geometry properties.

In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this art/science/math activity, young learners are introduced to the concept of symmetry in nature.

In this activity, learners use their hands as tools for indirect measurement.

In this activity, learners cutout a set of shape finder templates to explore shapes in the world around them.

In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

In this activity, learners discover what buoyancy is and determine the characteristics that make an object buoyant. Learners design, build, test, and evaluate boats made from a variety of materials.
