Take your time with this lesson. Junior engineers read about different types of clocks and then work together to build a pendulum time-keeper. There are no hints as to how they might go about accomplishing this complex task, so you may...

Take a trip through time. A lesson resource provides instruction on the origin of current measurements for time. The text explains the different tools humans used throughout history to measure time as well as provides examples such as...

Learners determine how to find North using a watch and their shadow. In this finding North instructional activity, students go outside on a sunny day and work with their shadow and a wrist watch to find out which direction that North is....

Students measure shadows to learn about the Sun-Earth relationship. In 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...

Fourth graders discover time keeping by analyzing technological advances in history.  In this time lesson, 4th graders create and complete a KWL chart based on their research of a famous timekeeping invention, such as a sundial....

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. 

Students investigate time, how people measure it, and how it influences our lives. They complete an online Webquest, analyze various calendars, answer discussion questions, and identify references to time in a newspaper article.

You have to crack a few eggs to make a good engineer! Working in small groups, young scholars design, build, and test devices that protect an egg from breaking when dropped from a ladder.

Students 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...

Students take a medical issue and explore it, debate it, and convince others of their point of view. They improve research skills and writing skills. Students are able to define a problem, debate it, and identify which is the best...

Could you reinvent the light bulb? Scholars tap into their inner Thomas Edisons to build a light bulb prototype out of a jar and some wires. They see how long the filament wire glows in the jar (batteries not included) to measure their...

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...

Students become aware of the effects of tides on the Earth's rotation. In this tides lesson, students calculate the number of seconds lost over various periods of time.

Learners work collaboratively to predict what life would be like as an Arctic Hare. Teams go on a hunt where scholars role play an owl, white hares, and gray hares. Independently, pupils record their findings and reflect on their...

How quickly does a plant transpire? Learners explore this question through measuring water uptake with a potometer. They time the movement of a bubble a set distance to understand the motion and rate of speed.

In this tower building and budgeting worksheet, students attempt to meet the goal of building the tallest free standing structure on the smallest budget. They build the structures with straw, paper clips, and masking tape which all have...

Students discover the contributions of early astronomers and scientists. In this research skills lesson, students research electronic and print sources about Galileo Galilei, Aristarchus, Hipparchus, Claudius Ptolemy, Nicholas...

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

Tenth graders should explain some basic properties of electricity and know how electricity is produced. They should also explain the electrical components that make up electric circuits.

Students participate in an experiment that shows them how wetlands filter dirty water. They work in groups to accomplish this experiement with the help of supervisors. A bulletin board can be created to show the plants and animals that...

Working in teams, students build their own pendulum clock using everyday materials. They conduct research, design, build, test it, and share observations with the class, while learning how pendulums operate and have been used to measure...

Being able to sense time helps us do everything from waking and sleeping to knowing precisely when to catch a ball that's hurtling towards us. And we owe all these abilities to an interconnected system of timekeepers in our brains. But...

Morning glories unfurl their petals like clockwork in the early morning. A closing white waterlily signals that it's late afternoon. And moon flowers, as their name suggests, only bloom under the night sky. What gives plants this innate...

Learn about prominent Dutch mathematician and scientist, Christiaan Huygens, whose work included early telescopic studies of the rings of Saturn and the discovery of its moon Titan, the invention of the pendulum clock, and other...
