Repeat steps 2 - 5 a few times (repeat 3-4 times for more accurate results).

Note the time on the stopwatch and reset.

Wait until the Sun has moved to just outside the circle you drew.

Trace around the image of the Sun on the screen.

Angle the solar reflector so that Sun is reflected onto the screen.

If it does move you will have to start all over again!screen up and make sure it cannot move during the experiment - if it does move you will have to start all over again. Stand it up and make sure it is stable and will not move during the experiment. If you don’t have a tripod, put plasticine/playdough on the floor in an L-shape (as demonstrated in the photograph below) and embed the block on it so that the mirror is at about a 40-degree angle (facing the Sun).

Tape the mirror to the tripod, so that the mirror faces up. Ensure that the hole is over your mirror, covering up nearly all of the reflective surface. Tape the paper with the hole to the front of your mirror. All you need are some household items and about 20 minutes on a sunny day.Ĭut a small hole in the centre of the piece of thick paper. By measuring how fast the Sun moves you can work out how big the Sun appears in the sky. The Sun moves across the sky at a constant rate because of the rotation of the Earth. The speed the Sun travels at is:ģ60 degrees / 24hours = 360 deg/(24圆0) minutes = 0.25 deg per minute = 0.00416 degrees per second or 1/240 degs per second Instructions It takes 24 hours for the Sun to travel 360 degrees, all the way around the sky and return to the same position it was in the previous day. However, many people do not possess an accurate idea of the scale of the Sun relative to the Earth.

Our lives are dominated by the movement of the Earth relative to the Sun, we use these movements to measure time: one day is the length of a full rotation of the Earth on its own axis and one year is a full orbit of the Earth around the Sun. The Sun is the centre of our Solar System, provided all of the light and heat needed to support all living things on our planet.

A pencil or marker pen which will write on the screen.

Something to use as a screen (a big sheet of white paper with a cardboard backing will do).

A tripod or a lump of Plasticine or playdough.

A piece of thick paper to cover your mirror.

Students will develop an understanding of the scale of the Sun compared to the Earth and the Moon.įor this activity you will need the following apparatus:.

Students will learn how to measure the movement of the Sun across the sky and use their results to calculate the angular and physical size of the Sun.

Students will understand the fixed speed of the Sun as it appears to travel across our sky.

GoalsĬarry out your own experiment and use your results to calculate the diameter of our closest star the Sun. All you need are some household items and about 20 minutes on a sunny day. In this activity you will measure how fast the Sun moves to caclulate how big the Sun appears in the sky.
