What would be different about a sundial in the north pole?
A sundial in the north pole would have a steeper and shorter gnomon compared to sundials in lower latitudes. The spacing of the hour markers in a sundial in the north pole would be same; the hour lines would be 24 hours.
What is the pin of a sundial whose shadow points to the hour called?
It is called a Gnomon
How do you read time on a sun dial?
When the sundial is properly alligned, the pointy shadow works just like the hour hand on a clock.
What is the procedure for making a sundial?
In order to make a sundial, find a piece of wood that is about three feet square. Drill a hole in the center, insert a 7 inch dowel, and place the structure outside in full sunlight. At the start of every hour, mark the dowel's shadow with a tack. After you have finished, check the sundial for accuracy against a clock and make adjustments if necessary.
How does a sundial tell time?
We have days and nights on earth due to the Earth rotating around axis. Approximately over 23.6 hours our Earth makes one complete rotation and as we rotate, we rotate away from the sun (night) and back towards it (day). A sundial works by gauging the suns position in the sky relative to where we are in that 24 hour period. The sun casts shadows on the sundial in different places as it moves across our sky, indicating different times. The time piece on the sundial is called a "gnomon" and by reading where the shadow falls when the sun hits the gnomon we can estimate the time of day.

What is a sundial calendar?
A sundial is pretty much an analogue clock, except instead of hands, it uses the suns shadows to point at hour lines on its base.
What is Spaced learning and Massed learning?
Spaced learning is learning or studying information in intervals in time, such as studying for half an hour, going to eat, studying again for half an hour, cut the grass, study again for half an hour. Massed learning is studying or learning a lot of information over one big period of time, such as studying 2 chapters of a biology book for 3 or 4 hours.

How to Incorporate a Sundial In Outdoor Decor?
Since the discovery of time, sundials have fascinated humankind. Sundials enabled people to tell time in older days. Fortunately in modern times, people now have the luxury of reading time by use of clocks. Sundials have not lost their luster completely; people continue to use them in outdoor decor. Follow these steps to choose and care for a sundial in your outdoor decor. Step 1: Educate yourself on the use of a sundial. There are three main components of a sundial, the dial plate, dial centre and the gnomon. The gnomon component casts the shadow onto the sundial, giving indication of time. The dial plate or clock part of the sundial is the face of the sundial where it indicates the hours and the shadow from the gnomon is cast. Hour lines of the sundial meet at the dial centre component, at the north base point of the gnomon. As the Earth rotates and the sun moves across the horizon, the shadow is cast from the gnomon onto the dial plate. The landed shadow indicates the hour. Step 2: Consider the type of sundial. Most commonly used for gardens and parks are horizontal sundials. This sundial has a flat dial plate, aligning the locations latitude with the gnomon. Equatorial sundial plates are parallel to the equator, with the gnomon vertical to the plate. A polar sundials dial plate is placed parallel to Earth’s polar axis, where an analemmatic sundial places you as the vertical gnomon. Step 3: Choose the style of sundial. Sundials are made from many materials such as bronze, brass, marble, aluminum or cast iron. Each material must be cared for uniquely and range in price. Step 4: Set up your sundial. Sundials usually come with their own specific set-up instructions. However, all sundials need to be placed facing north with the gnomon equal to your latitude. Step 5: Provide maintenance for your sundial. Aluminum sundials are the most resilient to the elements; washing with a mild soap and thorough rinse you can keep your sundial vibrant. Brass and bronze materials should be occasionally polished with a quality metal polish to keep the metal gleaming. It can also be left to age naturally where it will begin to show a green coloring giving an antique finish. Clean your marble sundial with a mild soap and soft cloth, rinsing thoroughly. Abrasive or acidic cleaners may damage the marble stone. Fungus can be removed from the marble with a mild bleach solution and a thorough rinse. Cast iron sundials are susceptible to rusting; repaint your cast iron sundial with a rustproof metal paint to keep it looking new. Sundials are a unique outdoor decoration passed down from our ancestors. Understanding sundial components, the types of sundials, the care and maintenance of your choice of sundial will keep your outdoor garden area elegant and functional.
