by:  Norm Barstow

The first practical design of the hovercraft was completed in the late 1950’s by British engineer, Sir Christopher Cockerell.  Since then, the continued development of this invention has been ongoing, and currently, the hovercraft is being used commercially, by the military, and for personal use.  Teachers have been constructing versions of the hovercraft using balloons, film canisters and flat materials in classrooms for years.

Gro-Beast Alligators


Jill BrownBy : Jill Brown

Each year I purchase the Gro-Beast Alligators from Educational Innovations for my Fourth Grade class.  These growing alligators start at about three inches long and grow to over a foot long when placed in water!  From this one item, I have developed lesson plans that incorporate Math, Science, Reading, Social Studies, Writing, Technology, and Language Arts!Gro-Beast Alligator

Observation is the first action taken by learners to acquire new information about an organism; therefore, the first thing my students do is observe their polymer alligator.  The students in the picture below are in the process of measuring the length, weight, circumference, and area of their polymer alligators. Students in my class also trace their alligators on graph paper then they calculate the area of each and eventually compare the area of their small (dehydrated) alligator to that of their fully grown alligator. (Math & Writing & Language).  These measurements are compiled into a line graph for each student’s crocodile which aids students in making predictions about the rate of future growth of their growing reptile.  Read the rest of this entry »
