In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.

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.

In this math lesson, learners compare pattern blocks to visually understand halves, thirds, and sixths.

In this activity, learners play a game similar to Tic-Tac-Toe. In this version, learners try NOT to get three-in-a-row. The player who gets three-in-a-row first loses!

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 observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this fun math activity (page 1 of the pdf), learners exercise the creative part of their brain by trying to describe a number without mentioning the actual number (for instance, the number 12 could

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

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.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners will first learn the basics of galaxy classification and grouping.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.
