In this simulator you are able to move the little stickman on the surface of the earth (upper right) and upon deciding on a latitude, then watch how the rays of the sun change angles throughout the year. If it might make more sense to grade one students, this also allows for comparisons of how many light rays are hitting the same area. In the picture to the left, (which is simulating mid-February) there are five rays hitting the surface. When the date is moved to the end of June (our favourite time of year) there are now eleven rays hitting the surface. One can also return to a given date (like mid-February), and upon moving the latitude of the stickman,  we see twelve rays hitting the same area. This may help students to understand the different seasons at different time of the year, and why locations like Australia are having their winters when we have our summers.

Stellarium is an incredible simulator that will help you to show your students the difference in where the sun rises and sets throughout the year, and the difference in duration of sunlight throughout the year. This will really help in students grasping why we even have seasons. As an example, in the image to the left, the date is set to the winter solstice, and the sun is rising in the north-west at 9:00 in the morning. Contrasting this, when the date is set to the summer solstice, the sun is rising in the north-east at 5:00 in the morning. This really helps to illustrate the differences in the sun's height in the sky and its duration that it is visible in the different seasons.
