Use trigonometry to determine whether solar eclipses on earth can be perfect.
Make an accurate diagram of the solar system and explore the concept of a grand conjunction.
Make your own pinhole camera for safe observation of the sun, and find out how it works.
The third installment in our series on the shape of astronomical systems, this article explores galaxies and the universe beyond our solar system.
This article explores ths history of theories about the shape of our planet. It is the first in a series of articles looking at the significance of geometric shapes in the history of astronomy.
Making a scale model of the solar system
The second in a series of articles on visualising and modelling shapes in the history of astronomy.
Mathematics has always been a powerful tool for studying, measuring and calculating the movements of the planets, and this article gives several examples.
How does the time of dawn and dusk vary? What about the Moon, how does that change from night to night? Is the Sun always the same? Gather data to help you explore these questions.
Mathematics has allowed us now to measure lots of things about eclipses and so calculate exactly when they will happen, where they can be seen from, and what they will look like.
