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

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...

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...

Middle schoolers explore the difference between analog and digital televisions. They examine how the technology works and the impact of television through history. They also compare older television sets to ones found today.

Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson plan, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

Digital, analog, and now binary clocks? The instructional activity teaches individuals how to interpret binary code. They use an online software program to read binary clocks.

Fifth graders investigate how chemical energy in food and batteries is potential or stored energy. They discuss how batteries function, and create a class list of different forms of energy. Students then create a lemon battery that...

Fifth graders explore and examine the basic properties of sound. In pairs, they speak through a balloon and listen to the sound vibrations, and listen to a ticking clock or watch through a variety of materials and identify the...

Students investigate time. In this investigative lesson, students run through an obstacle course using standard timers. They record the time and apply this knowledge to problems in math. Students record their predictions, and graph...

Students explore the amount of electricity used and wasted in homes and at school using kilowatt meters. In this environmental energy lesson, students compute power usage by appliances over time and identify ways in which...

Students explore time management by participating in itinerary activities. In this time telling lesson, students identify how to read a clock, how to communicate the time to others and how to plan for events in the day. Students practice...

Students explain how cell phones work. In this physics lesson, students describe the advantages and advantages of having one. They identify the different parts of a cell phone.

Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.

Students study time and how to accurately calculate it.  In this time lesson students complete a lab activity in pairs and discuss their findings. 

Sixth graders investigate time, distance and speed. In this math lesson, 6th graders convert elapsed time into hours, minutes, and seconds. They analyze a marathon to find data on elapsed time.

Learners work together to identify the accuracy of sundials. They track the position of the sun and create a shadow plot. They discover the difference between real time and clock time.

Students observe bird feeding and complete a tally and graphing activity for their observations. In this bird graphing lesson, students work in teams to observe bird feedings. Students complete a bird reporting sheet and collect data...

Students simulate the dating process with popcorn. In this geology lesson, students discuss how geologist find the age of rocks by gauging the amount of decay of radioactive elements. They have 6 bags of popcorn and each group microwaves...

Students compare and contrast a cell and a battery. In this physical science lesson, students explain how they create energy. They conduct an experiment to apply what they have learned in this lesson.

Students, in groups, identify examples of shapes around the school site. They take digital pictures of these shapes and use them to construct a class book.

Students utilize the scientific method to design a way for a balloon to be suspended between the floor and the ceiling.

Students examine the phenomenon of sounds traveling slower than light. They discover why they see things before they hear them and how to estimate the speed of sound as homework.

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...
