Explore each of the formal compositional principles below. In some cases, several principles may be involved in the composition of the image. This is fine, but the principle you choose should be what you feel is the PREDOMINATE one in the look of the image. Submit one image for each principle below.

•What are the elements and principles used?
The elements used in this photograph are colour, form, and shape. Colour is evident as shown through the various colours the paper stars are, from pink, blue, yellow, orange, green, and red, this image displays multiple colours. Form and shape is found in the shape and “structure” of the stars. As the stars were falling at different angles, different perspectives of the star were captured. Therefore, this accentuated the form and shape of the stars. The principles used are movement, harmony and unity, proportion, and repetition. Movement is found in the direction from which the stars were falling. Although they were falling out of the hand, the stars in this photograph make it appear to be gravitating towards the hand, therefore showing movement. Harmony and unity is shown through the number of stars. All the various stars in this picture work together to accentuate other elements and principles of design, such as movement and repetition. Each star in this picture affects the picture in some way or another through how they contribute to movement or to give colour to the image. Proportion is shown through the contrast of the hand compared to the size of the stars, and finally repetition is most prominently displayed through the abundant amount of stars.
•How did you take the photograph?
I took this photograph by setting it on a table and not a tripod. I then set it on a high shutter speed of 1/1000. This was so to correspond with the requirement of a high shutter speed in order to capture a frozen motion. I then focused my hand, a distance from the camera from where I was going to drop the stars, then I released the stars.
•What difficulties did you encounter?
Some difficulties that I had encountered while taking this photograph, was getting the photograph to be in focus, and getting the stars to fall in a way that would capture the example of freeze motion. At first, the photographs wouldn’t come out in focus and were often blurry. However I learnt that I should focus the object (in this case, my hand) in a distance from the camera where I would drop them. This made my pictures become more in focus. Secondly, there was difficulty in getting the stars to fall in a way that would be appealing. Eventually, I realized I had to release the stars more slowly in order to obtain the stars suspended in different heights.
•Why is this best example?
I feel that this is the best example as it shows different heights of the falling stars, emphasizing further the fact that this photo was taken for the purposes of showing a moment in time. Additionally, this photo demonstrates several elements and principles such as colour, movement, repetition, and harmony.
•Why is this your best example of motion?
I feel that this is my best example of motion as it shows the type of motion photography I was trying to achieve the best. The picture has a definite focal point (the hand) and also has many different elements and principles used, far more than the other images. Also, I feel that this picture is more visually appealing and interesting to a viewer due to the abundance of stars that make the viewer look at all the different angles. This also adds to the complexity of the image making it more captivating and overall more attractive.
•How did your editing enhance the image?
The editing that was done enhances the image by making it brighter. This was done as so to make the image look less dull, compared to how it appeared before. This therefore changed the mood, and atmosphere of the picture by making it seem much lighter and more cheerful. Making this image brighter also helped bring out the vibrant colours of the stars even further adding to the general effect of the photograph. Also, my editing also helped removed an amputation in the corner of the photo, making it appear less distracting to the viewer.

Balance is important to this composition as the visual weight of the elements is what makes up the balance. This image focusses on the more informal aspect to balance meaning it is assymetrical.
Depth of the Fore/Mid/Background is also important as it showcases the technique of overlapping elements to parcially obscure one cactus with another which emphasises the depth.

Introduction to Geothermal Energy
1. Definition and Basic Principles of Geothermal Energy:
Geothermal energy originates from the heat within the Earth's sub-surface. It's a renewable energy form that natural processes like radioactive decay continuously generate. The Greek words "geo" (earth) and "therme" (heat) combine to form the term "geothermal", effectively translating to "Earth's heat."
We can harness and use this heat in various ways. The Earth's temperature at shallow depths remains fairly constant throughout the year, which can be utilized to heat and cool buildings with geothermal heat pumps. At greater depths, temperatures can soar to hundreds of degrees Celsius. These conditions create geothermal reservoirs, from which we can extract steam and hot water to power electricity-generating turbines.
2. History of Geothermal Energy Use:
People have been using geothermal energy since ancient times, for bathing, cooking, and heating, with hot springs serving as the source. Historians believe that the oldest known spa, a stone pool fed by a hot spring, was built on Lisan Mountain, China, in the 3rd century BC.
The early 19th century near Pisa, Italy, marked the first industrial use of geothermal energy. Here, people used steam from natural vents to extract boric acid from volcanic mud.
In 1904, the first test of a geothermal power generator took place in Larderello, Italy. This generator successfully lit four light bulbs.

It is widely accepted that there are no silver bullets or perfect solutions to our global and local sustainability challenges. The reality of developing solutions is messy, imperfect and there will be compromises and trade-offs. The more schools set an example of trialling, testing, learning and adapting, the more they will have a positive influence on the values of tomorrow’s leaders.
