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

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this math lesson, learners extend their understanding of basic probability concepts as they learn to name all of the possible outcomes of an event as well as ways to express the likelihood of such

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

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

In this math lesson, learners make wallets or purses and then participate in a variety of money-related activities. First, learners make their own paper money and paper wallets or purses.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

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.
