This lesson will help children relate the concepts of past, present and future to their own lives. This lesson will be 45 minutes and include discussions, book reading and coloring. The children will learn the vocabulary words: time, yesterday, today and tomorrow. They will be able to relate this to personal experiences in their own lives. Materials:CalendarWhite board, white board markersHoughton Mifflin Social Studies Teacher Edition Level K My WorldWorksheets for all 15 studentsPencils and crayonsBig Ideas / Essential Questions:What is the difference between last year, this year and next year?Can you describe some of these differences using examples from your own life? 

In this activity, students will practice talking about time and movies. They will learn how to read the clock in Arabic, recommend a movie based on someone's preferences, and understand schedules.Can-Do Statements:I can understand the time when announced or shown to me.I can identify movies with the times they take place on a schedule.I can recommend a movie for someone according to his/her preference.

The CyberSquad must construct a clock of sorts in order to keep track of the amount of time they have to rescue Dr. Marbles in this video segment from Cyberchase.

Students will practice telling the time from visual and verbal cues. They will also practice responding to situations with separable prefix verbs.

Students investigate the accuracy of sundials and the discrepancy that lies between "real time" and "clock time." They track the position of the sun during the course of a relatively short period of time as they make a shadow plot, a horizontal sundial, and a diptych sundial. (The activity may be abridged to include only one or two of the different sundials, instead of all three.)

Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.

Students learn various topics associated with the circle through studying a clock. Topics include reading analog time, understanding the concept of rotation (clockwise vs. counter-clockwise), and identifying right angles and straight angles within circles. Many young students have difficulty telling time in analog format, especially with fewer analog clocks in use (compared to digital clocks). This includes the ability to convert time written in words to a number format, for example, making the connection between "quarter of an hour" to 15 minutes. Students also find it difficult to convert "quarter of an hour" to the number of degrees in a circle. This activity incorporates a LEGO® MINDSTORMS® NXT robot to help students distinguish and visualize the differences in clockwise vs. counter-clockwise rotation and right vs. straight angles, while learning how to tell time on an analog clock. To promote team learning and increase engagement, students work in teams to program and control the robot.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts. Escapements are found in mechanical clocks, such as those driven by a pendulum or a spring. Learners will build the wrapping form of escapement said to be used in a fifteenth-century German clock.

Students experientially learn about the characteristics of a simple physics phenomenon the pendulum by riding on playground swings. They use pendulum terms and a timer to experiment with swing variables. They extend their knowledge by following the steps of the engineering design process to design timekeeping devices powered by human swinging.

This lesson includes a video which is an introductory video to telling time on a digital clock to 5 minutes. It goes over these vocabulary terms: short hand and long hand, the minute hand and hour hand, half past, o'clock, quarter after, and skip count.There are three worksheets each a little harder than the last. The video includes a song which will help students remember how to tell time.

Students further their understanding of the engineering design process while combining mechanical engineering and bioengineering to create assistive devices. During this extended activity (seven class periods), students are given a fictional client statement and required to follow the steps of the engineering design process (EDP) to design a new wristwatch face for a visually impaired student at their school. Student groups share their designs with the class through design presentations. A successful design meets all of the student-generated design requirements, including the development of a new method of representing time that does not require the sense of sight. Through this activity, students design, construct and iterate classroom prototypes of their watch designs.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Cryptochrome proteins help organisms from plants to insects to mammals set their biological clocks to the rising and setting of the sun. But while the often photoreceptive N-terminal domain is highly conserved a distinctive C-terminal tail diverges and is a distinctive feature of cryptochrome (CRY) proteins in organisms ranging from plants to insects to mammals. Growing evidence suggests that this intrinsically disordered C-terminal tail binds reversibly with the N-terminal domain modulating the feedback loop that generates a circadian oscillation of gene expression with a period of approximately 24 hours. In humans, the intrinsically disordered tail of the protein CRY1 was recently linked to circadian timekeeping and delayed-phase sleep disorder or “night owl” behavior. Further studies examining the role played by CRY1’s tail could help researchers understand how intrinsically disordered regions in proteins affect circadian timing and how that timing runs out of sync with the environment..."
