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.

In this activity (14th activity on the page) about the sense of touch, learners examine if it is easier or harder to identify an object if they move their hands over it.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

In this number puzzle/trick, learner #1 thinks of a number between 1 and 63. Learner #2 shows learner #1 six cards and asks them whether the cards contain their number.

In this activity (13th on the page), learners complete a simple illusion trick to see through their own hand.

In this activity, learners create an origami model of DNA, demonstrating its double helix structure.

In this activity, learners will write a secret message that only their friends will be able to read.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.

In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

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

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

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.

In this activity, learners will explore their center of gravity.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.
