In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this design challenge, learners will practice empathy and design thinking skills by creating an invention of the future.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

Este Web site contiene links a 12 calendarios (12 meses). Cada mes contiene actividades sobre matemáticas.
