Students discover time keeping by reading clocks.  In this time-telling instructional activity, students read the story Hickory Dickory Dock, and discuss the measurements of time we use.  Students complete worksheets in which...

First, second, and third graders explore elapsed time through estimation and prediction. They work with a partner to estimate how long it will take to perform various tasks. One person uses a stop watch to time his or her partner...

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

Learners review telling time to the hour and half hour on an analog clock. In this time lesson, the students learn how to determine the time in each of the 4 standard time zones.

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...

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

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...

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...

Discover an inverse variation pattern. A simple lesson plan design allows learners to explore a nonlinear pattern. Scholars analyze a distance, speed, and time relationship through tables and graphs. Eventually, they write an equation to...

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...

The distinctive attire of royalty, working class, and peasants of the Victorian era conveys much about the conditions of the time. Learn more about why people dressed as they did, and how their fashion changed during the 64-year reign of...

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...

Students make sensible estimates and check the reasonableness of the answers. Students write and solve problems involving decimal multiplication and division. Students perform calculations with time.

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,...

Middle schoolers place a pencil perpendicular to the ground and trace its shadow between 11:30 AM and 12:30 PM. They measure the length of the shadow, periodically over several hours, in either English or Metric units. Using the data,...

Students create a shadow clock. In this time lesson, students make their own shadow clock or sundial from tag board. They place it on the ground and check it every hour to mark where the shadow lies.

Students read an article about robots and social behavior. As a class, they write down new vocabulary words they are unfamilar with in the article. In groups, they discover what all the words have in commom and identify the type of...

Young scholars turn on a flashlight and leave it on until the energy is used up (12-36) hours. They estimate or preduct how long they think the energy in the batteries will last. They then estimate how long a birthday candle will burn,...

Sixth graders identify the parts of a flower, and tell the difference between monocots and dicots. They group plant by leaf types and characteristics placing the information in table form on the computer.

Middle schoolers practice estimating distance traveled while walking. Also can be used to introduce backpacking/hiking or as a daily warm-up. Measure the blacktop/cafeteria/playground, then determine how many times around make a mile.

Fourth graders graph the number of daylight hors throughout the year and examine why day length varies. They discover that seasonal changes and latitude on Earth affect the number of hours of daylight in each day. Students listen to...
