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.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this activity, learners compare the number of letters in the names of the people in their families or group of friends.

In this activity, learners explore mammal locomotion by constructing flipbooks.

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.

Jugando a este juego de estrategia, los chicos desarrollan su entendimiento de área y perímetro. En su turno, cada jugador hace una línea entre dos punto contiguos en la cuadrícula.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

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 activity, learners work in partners to create and exchange messages written in Braille. Learners use a Braille key and thumbtacks to write their messages in Braille.

In this online puzzle game, learners need to choose a path from a starting number to a goal number. Along the path are simple operations (e.g.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

This activity was designed for blind learners, but all types of learners can use it to learn to differentiate between qualitative and quantitative observations and to practice data collection.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this physics activity, learners experiment with soap bubbles to see what variables affect their size. They explore how soap film and bubbles always seek the smallest surface area possible.
