The whole class discusses the differences between the two clocks: digital and a clock with hands. They discuss the differences between the hour hand and minute hand. Students are taught telling time to the half hour. They are introduced...

Students investigate how to tell time by observing the placement of objects in the sky. Researching on the Internet, they locate the time for sunrise and sunset, the time the full moon rises, and the difference between clock and solar...

Third graders investigate the events of geological time using a chart called a "Clock of Eras". In this geological events lesson plan, 3rd graders compare a standard clock to a geological clock. In addition, students consider periods...

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 demonstrate that the movement of the sun causes shadows which were used as the first indicators of telling time.

Students construct clocks and then learn how to read a clock face, tell time, and determine how much time has elapsed.

You can't tell by the title, but this is a functional periodic table of elements. Incorporating bright colors, lucid text, and easily operated features, this application serves as a valuable reference tool for your chemistry class.

Young scholars explore space science by completing a worksheet in class. In this astronomy lesson plan, students discuss and identify star patterns in the night sky and relate these patterns to the approximate time they appear. Young...

Students make shadow clocks. In this earth science lesson plan, students follow the provided steps to make shadow clocks out of the provided pattern and tagboard. A game, a song, a craft, and a recipe are all included with the...

Students determine how to find North using a watch and their shadow. In 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...

Whether you have your class plant seeds or begin when sprouts are visible, math skills are used here to predict and track growth over time. Straw bar graphs show plant height on a given day while the graph as a whole shows changes over...

The video clip that comprises the warm up is not available, but the related article from The New York Times and the movie trailer for Aliens of the Deep are, leaving enough material to make this a fascinating lesson on deep-sea...

How can you tell what an owl has eaten? Study the food chain and flow of energy in an ecosystem by dissecting an owl pellet and noting the bones found inside. Additionally, the lesson includes a game about consumers and producers with a...

Pupils design a calendar that displays time on Mars. They explore the differences between time on Earth and time on Mars while making the calendar.

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

What can shadows tell us about the changing season? Over several months, astronomy learners record length and position of an outdoor object's shadow, such as a flagpole. They apply the data to a growing hypothesis and note the...

Engineering design projects serve as great opportunities for collaborative problem solving. In this case, students work in small groups designing, building, and eventually testing a structure that meets a teacher-specified objective. It...

Youngsters pretend they are rocks sitting on a hill. They listen to the provided guided imagery script to conceptualize the process of how rocks change over time. They draw a diagram of what happened to them as rocks during the story. An...

Inform your elementary scientists why we experience day and night. They are provided with facts and explanation as to why the day and night cycle occur, discuss what they've learned with a partner, and are then given the task of writing...

Exactly what do groundhogs know about weather? Not as much as your science students will after completing these lessons and activities that cover everything from the earth's rotation and the creation of shadows, to cloud...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

Fifth graders examine plant and animal cells. In this plant and animal cell lesson, 5th graders define what cells are, label their parts, and describe how plant and animal cells are different. They observe cells at a number of web sites,...

Learners examine the use of satellites. In this research lesson, students discuss the history of satellites and how we use the information today. They will conduct interviews with older adults who have lived in the changing times from...

Hopefully by the time high schoolers are enrolled in your chemistry class, they are skilled with unit conversion. It does not hurt, however, to take an hour early in the school year to review this vital skill. This plan simply provides a...
