Students examine how a rate is calculated from two points. Using battery operated cars, pairs of students measure time and distance. Afterward, they use this data to calculate the rate. Students then plot four ordered pairs and discover...

Students determine how to find North using a watch and their shadow. For this finding North lesson, students go outside on a sunny day and work with their shadow and a wrist watch to find out which direction that North is. They examine...

Students measure shadows to learn about the Sun-Earth relationship. For this astronomy lesson, students create a shadow stick of a Pokemon character and record measurements of its shadow in a data chart. Follow-up discussions guide...

Students study trees and their growth.  In this investigative lesson plan students work in groups to reconstruct a 50 year climatic history using a simulated tree ring. 

Young scholars examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an...

Young geographers collect samples of different kinds of soil to match to the soil terms in Barry Rudner's rhyming book Filet of Soil: dirt, mud, dust, soot, etc. They start a glossary for the project on index cards or large sheets...

Learners demonstrate basic construction skills by building a free standing structure. They compute the cost of the structure.

Students investigate how to create a free standing structure. In this mathematics lesson, small groups of students demonstate how to build the tallest structure while spending the least amount of money on materials.
