Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

In this activity, learners will explore pi and the mathematical relationships between a circle's diameter, circumference, and radius.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this environmental activity (page 6 of the PDF), learners identify household products that are recyclable and explore the different types of recyclable plastics.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this activity, learners build small animated toys that move.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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

Build your own version of the classic physics toy using simple materials.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.
