# GPM Core Observatory Paper Model

This activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together... (View More)

# Estimating Planar Areas Using Analogue Methods

This math problem determines the areas of simple and complex planar figures using measurement of mass and proportional constructs. Materials are inexpensive or easily found (poster board, scissors, ruler, sharp pencil, right angle), but also... (View More)

# Teaching Radicals in Less Than Five Minutes

This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More)

# The Fall of the Ruler

This activity shows how an ordinary ruler can measure human reaction time (RT). Learners will convert a standard ruler into a time ruler (relating time and distance) and measure each others RT. They will also calculate means and variances and the RT... (View More)

# Modulus in Real Life

In this example, a computer scientist describes how the remainder in integer division has utility in pattern recognition and in computer programming. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples... (View More)

# There's Air in There!

In this demonstration, a soda bottle, paper and straws are used to show learners that air has mass and takes up space. The activity is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and... (View More)
