Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

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.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.

Learners examine what happens when a tube spins in two directions at once. They push on a cardboard tube causing it to spin along its length while at the same time turning from end-to-end.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.
