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...

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

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...

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...

After a discussion of chemical reactions and electricity, scholars break into groups and follow a scripted activity to discover if fruit can power a clock. After a concluding discussion, the class a presented with a challenge.

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.

How can a robot measure the length of something when we don't know how far the camera is from the object? The lesson explains the concept of perspective and many others. Scholars apply this knowledge to judge the length of fish and the...

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 review the concepts of the branch of science known as astronomy. They discuss stars and constellations and then view the night sky using a portable digital planetarium projector. They identify a variety of constellations using a...

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...

Young scholars 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...

Learners 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. For 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.  For this time lesson students complete a lab activity in pairs and discuss their findings. 

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 work in groups to build a robot. In this robotics lesson, students create an electronic robot and program it to follow directions. They create an obstacle course for the robot to follow and test its performance. 

Students read a story called New Bulbs Provide More Light, Save Energyand answer vocabulary and comprehension questions about it. In this current events energy saving light bulb lesson plan, students respond to literature by answering...

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...

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

Students determine their respiratory rate and explore the factors that affect breathing rate.

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.
