When is daytime

Students should be encouraged to make use of observable features of astronomy. These observations can be made during the day as well as at night. They should then be guided to develop their own questions to research and explore. In this way the research is more directed and not simply a fact finding exercise. Opportunities to make models and to manipulate the models to help students explain their ideas should be provided.

The manipulation of models also assists students to view the motion of the sun, Earth and the moon from a new perspective of an observer of the whole system as opposed to their usual perspective as an observer on a very small region on the surface of the Earth. This can be used as a starting point to challenge existing ideas and to explore new ideas. Student drawings and their associated explanations of the motion of the Earth and sun can be used to challenge their existing ideas and to help them to reflect on their understanding.

To help students move from their usual perspective of an observer on a small part of the Earth to an observer outside the Earth simulation computer programs or websites can be used.

Students could present posters or diagrams suitable for display on an overhead or data projector to help them to interpret and share new perspectives with their peers.

Students could also explore indigenous interpretations of the motion of the sun and Earth. Some useful sites are:. Our website uses a free tool to translate into other languages. Stop it, there is no need for it any longer, leave it so we have a little more light in the winter afternoons, and longer summer evenings Every year twice for a week my system is messed up until it adjusts.

This is not something we need if we ever did. Leaving it DST all the time makes most sense to me, since "standard" isn't even five months anymore. After all "standard transmission" is now called "manual", since automatic is the most common in vehicles.

Or, keep it Standard year round since that's best for our bodies. We have more efficient devices and lighting now than in the 's. Time change sucks, each direction.

We should leave the clocks alone and follow the sun. We should follow the cows, the chickens, the huskies, the lyons, the tigers, and every living things that is around. Who are we to disrupt their daily life cycle?

We should learn from them and leave as naturally as possible. Let's follow the sun and the moon instead of the clock and all electronic devices.

This ridiculous law needs to be repealed. The native Americans said it best: Only a white man would believe you could cut a foot off the top of a blanket, sew it to the bottom, and have a longer blanket. I wish DST was year round. Hate seeing it get dark at 4 in the afternoon during the winter. Love the light later.. Who wants it getting dark at 8 in the middle of summer? I think DST is awful.

Time doesn't change. Silly people change time. It makes everyone feel bad. I am always glad when clocks go back to REAL time.

I personally cannot stand DST! I absolutely hate driving home from work in the dark. Please stay with standard time! I think DST is ridiculous and we should do away with it.

Personally I'm tired of always changing the time for this. Keep the DST and don't change it again. That's not natural. Why are we always messing with nature? Standard time is the best. It suits our natural rhythm the best. Switching back n forth is not healthy for anyone. Leave it at Standard time the way it should be. The other is artificial!!!! Unfortunately, even this article continued to mistakenly encourage the idea that Daylight Saving Time gave extra hours of daylight.

There are exactly the same hours of light, only the clocks have changed, not the daylight. I do not like the change and rarely run into anyone who does!

For those who like the concept let them simple wake an hour earlier to go to work and leave the rest of us alone with a consistent time.

The total day length is the same, of course. But, they will have one less hour or one more hour of daylight at the start of each day. We hope this helps clarify. Skip to main content.

It takes 24 hours for the Earth to turn all the way around rotation. That makes one day and one night. At any moment, half of the world is in daytime and half is in nighttime.

The world is like a ball. We call the top half the Northern hemisphere and the bottom half the Southern hemisphere. The imaginary line between them is called the equator. In summer the days are longer than they are in winter. In London, the longest day is about 16 hours and 39 minutes and the shortest is 7 hours and 45 minutes. In the Southern hemisphere the seasons are the other way around. When it is summer in Europe, it is winter in Australia.

Imagine celebrating Christmas on a long, hot summer day! To help us understand where we are in the world, we also split the world into right and left halves called the Eastern hemisphere and the Western hemisphere. The world is split into time zones. Continental Europe is in the time zone to the east of Britain, so time is one hour ahead there; when it is 1pm in Britain it is 2pm in France.

On the opposite side of the world from London is the International Date Line. On one side of the line time is 12 hours behind Britain, and on the other side time is 12 hours ahead of Britain. That means that it is a different day on each side of the line. Boost Your Child's Learning Today! Trial it for FREE today. The Earth is always spinning around — sometimes from where you stand on the Earth you can see the Sun this is the daytime and sometimes the part of the Earth where you are is facing away from the Sun so it is dark this is the nighttime.

It takes 24 hours for the Earth to spin all the way around, and we call this a day. Find out more about the sun and the Earth. The sun rises from behind the Earth in the East and sinks below the Earth in the West. The time when it appears is called sunrise, and the time when it disappears is called sunset. The length of time between sunrise and sunset is called daytime.

The Earth is also split into Northern and Southern hemispheres, which are divided by an imaginary line called the equator. The North and South poles are as far from the equator as you can get.
