The Boxes Go Mobile
Source Institutions
Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.
Geometry and Spatial Relations: Mirror, Mirror
Source Institutions
In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.
Measurement: How Many Noses Are in Your Arm?
Source Institutions
In this math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.
Buckets of Popcorn
Source Institutions
In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.
Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.
Now or Later: The "Recency/Primary" Effect
Source Institutions
In this activity (18th on the page), learners conduct an experiment to examine memory.
Carbon Sequestration
Source Institutions
In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra
Step Into Cyberspace
Source Institutions
In this activity, learners discover that they can modify a regular piece of paper so that it's large enough for them to walk through!
Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.
Graph Dance
Source Institutions
In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.
Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.
Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.
Crazy Shapes
Source Institutions
In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.
Scaling Cubes
Source Institutions
In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.
Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
Calendarios para cualquier año
Source Institutions
Este Web site contiene links a 12 calendarios (12 meses). Cada mes contiene actividades sobre matemáticas.
Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?
My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
