How to make a water clock

How to make a water clock Step 1. First, roughly measure halfway down the bottle, then carefully cut the bottle in two using the scissors. Step 2. Now, unscrew the top of the bottle and make a small hole in it using the drawing pin – ask an adult to help. Step 3. Next, turn the top half of the. Procedure Use the pushpin to make a hole in the bottom of a Styrofoam cup. Push the tip of the pin through the bottom of the cup Put a piece of masking tape straight up the side of a clear jar. Start at the bottom of the jar and make lines on the tape 1 cm apart. Fasten the Styrofoam cup to the.

Time marks most of the clocj in our busy, everyday lives. An alarm clock rings in the morning to wake us up. When the wall clock shows a. We eye the clock throughout the day to make sure we are on time and not late for some other activity.

Day and night, our watches, clocks, and cell-phone clocks help us to manage our time. But how did people keep track of time before the discovery of electricity, used in present-day watches and clocks, and before the development of gears used in pocket watches and pendulums in pendulum clocks from the s C. In ancient Egypt, the temple priests had to perform religious rituals at certain times of the day, so accurate timekeeping was necessary.

Sundials kept track of time during daylight hours and as long as the sun was out. Because accurate timekeeping during the night was also a necessity, the Egyptians developed the water clockcalled the clepsydra literally, "water thief" in Greek, in the 16th century B. A water what year did thomas jefferson became president is a device in which time is measured by the flow of water into or out of a vessel.

Since the water clock depends solely on the flow of water, it can operate at night or on days when the sun does not shine. The Greeks and Romans also wzter to depend on water clocks, and both cultures made improvements on the basic design. The latter half of watet 12th century C. Al-Jazari developed many cutting-edge devices; one of his most ot inventions was the elephant water clock. This clock was special not cloc, for accurately keeping time, but also for its amazing engineering.

Modern engineers have also worked on creating accurate water clocks. InFrench physicist and artist Bernard Gitton designed and built the cllck clock at the Children's Museum of Indianapolis.

It mke five years to perfect the design of this remarkable timepiece. The following video describes how this water clock works. In this mechanical engineering project, you will build a simple water clock — much wager than the one shown in how to make a mii puppy video! Figure 1 shows an example of a simple water clock; it tracks three hours of time. Figure 1. This image shows a possible mwke of a water clock.

Notice the upper container, the lower container, the float, and the float stick attached to the float. Three major parts make up the water clock that you will build: first an upper container from which water flows due to gravity ; second a lower container that catches the water w it flows out of the upper container; and third a "float stick" made from a cork and a wood dowel that enables a person to track time visually.

Z the water flows from the upper container to the lower container, the float stick rises. The distance the stick rises is clpck not only to the amount of water in the lower container, but also to how much time has passed; it indicates how much time has elapsed since the lower container was empty.

As the engineer in charge of mae project, your job will be to experiment and determine the best containers to use in order to create a water clock to track the passage of three hours of time. The Experimental Procedure below provides a general design to build the water clock, but you should feel free to use The Engineering Design Process to improve your own design and create a clock that appeals to you.

Figure 2. This image shows a flowerpot with some of the openings blocked with plumber's putty. Figure 3. Perform a water test on the upper container by filling it with water and making sure it does not leak after an hour. Figure 4. This image shows the float stick assembly inserted through the eyelets in the wood stake and the wood stake taped to the bottom container.

Figure 5. When you start your water howw, water should steadily drip from the upper q into the lower container, as shown in this image.

Troubleshooting Notes If you find, after any of the hourly measurements, that your water clock ran dry and thus could not track the whole three-hour time, it may be due to the upper container not being large enough, or the hole size being too large, how to keep liquid foundation from rubbing off the wood stake being too short. Stop the clock, and try to identify and fix the problem. Once you have a solution you want to try, restart the experiment at step 7b.

Since it is probably the easiest problem to test and solve, you may want to try restarting the experiment using more water in the upper container makke.

Mechanical Engineer. Mechanical Engineering Technician. Variations The change in hydrostatic pressure in the upper container as the water level decreases causes a change in the water flow mak rate. The accuracy of the clock depends on a constant water flow. How does the shape of the upper container affect the constant water flow and the accuracy of the clock?

Mxke with different container shapes. As you have seen, the accuracy of the water clock is dependent upon a constant water flow. How does the rate of water flow change over time in your water clock? Can you think of some ideas to keep the how to make easy boiled eggs level constant in the upper container? Put your ideas into action and see if the accuracy of your water clock lcock.

Head back in time with this cool science experiment!

Pour the water into the top of the bottle and then start timing. Each time a minute passes, mark a line at the water level of the bottom bottle. Mar 22,  · Making a water clock is an easy science project you can do with supplies you have around the house. It's educational and a great hands on project. This proje. Apr 28,  · Three major parts make up the water clock that you will build: (first) an upper container from which water flows due to gravity; (second) a lower container that catches the water as it flows out of the upper container; and (third) a "float stick" made from a cork and a wood dowel that enables a person to track time visually. As the water flows from the upper container to the lower container, the float stick rises.

How did people measure time before the invention of clocks or stopwatches? Well, the Ancient Greeks used a water clock called a clepsydra — and you can, too!

First, roughly measure halfway down the bottle, then carefully cut the bottle in two using the scissors. This can be tricky, so ask an adult to help.

Now, unscrew the top of the bottle and make a small hole in it using the drawing pin — ask an adult to help. Then put the lid back on the bottle. Next, turn the top half of the bottle upside down and place it inside the bottom half, so that the bottle top is facing downwards. Now, mix a few drops of the food colouring into a pint of water, and then have your stopwatch at the ready! Pour the water into the top of the bottle and then start timing. Each time a minute passes, mark a line at the water level of the bottom bottle.

Once all the water has passed into the bottom bottle, pour the water back into the top half and count off the minutes as the water pours down. Did you know…? Water clocks are thought to be one of the oldest time-measuring devices in the world — some have been found that date back to the 14th century B.
