In this clock construction lesson, students use a pencil, compass, and sun clock diagram to construct a homemade sun clock. A very interesting lesson on combining images with text.

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...

In this electrical circuit activity, students answer a series of 13 open-ended questions about digital-to-analog converter circuits. They analyze schematics in order to answer the questions. This activity is printable and the answers are...

In this electrical circuit worksheet, students answer a series of 18 open-ended questions about analog to digital converter circuits. They analyze schematics in order to answer the questions. Students design and build an analog to...

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 research water clocks online, investigate how water clocks work, and construct water clock that will keep time accurately for at least two hours without human intervention.

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 examine the importance of tracking time. In this critical thinking lesson, students discuss how people and animals track time and consider the consequences if people did not have clocks or calendars.

Learners put together a potato battery that powers a digital clock. For this potato battery lesson plan, students learn the connection between energy from biomass and how we can apply it.

Students make shadow clocks. In this earth science instructional activity, 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 ...

Pupils 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 complete experiments to learn about their internal body clocks and physiological activities. In this internal body science lesson, students read "Body Clock Investigations" and complete a body temperature investigation.

Students consider familiar audio and imaging devices, researching and analyzing the differences between analog and digital versions. They then reflect on which versions of the technology provide a truer record over time.

In this electronics worksheet, students build a circuit based on schematic diagram and answer 33 problems about it. They make prediction before testing and compare it with the actual value.

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

Could you determine longitude based on measuring time? Early explorers used a longitude clock to do just that. Scholars learn about early exploration and the importance of the invention of the clock. Then pupils build their own longitude...

Students recognize the elements of an analog weather forecast.  In this weather forecasting activity, students use a website and look for trends, persistence and climatology in weather forecasting.  Students complete a...

Students explore ways to turn back the genetic clock. They explore cells and mitosis. Students participate in an activity to create a flip book that will animate the process of mitosis. They explain each stage of mitosis.

Students investigate the effects of temperature and concentration on the rate of reactions. For this "clock reaction" kinetics lesson plan, students change the concentration of one reactant and keep the second constant. An indicator is...

Students create an earth clock.  In this earth clock activity, students create a clock which serves as a timeline of the history of the earth from 4.567 billion years ago to present day.  

Young scholars explore energy production by participating in a class discussion. In this renewable energy lesson, students discuss the differences between solar, coal, wind and fossil fuel energy sources and why some are better for the...

Students investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...

Students use string, wire, weights, and a stopwatch to build pendulum clocks. In this pendulum clocks lesson plan, students use the pendulum clocks to investigate weather, climate, force, and motion.

Students identify and use the starts to tell time just as people had for thousands of years. They identify the stars that appear to rise in the east and set in the west, and that those stars near the North Pole appear to go in circles...
