## Sea simulation

In junior high school maths, there are usually questions about measuring the angle of depression and/or distance using trigonometry. Common examples could be like "Find the angle of depression from a lighthouse beacon 112 m above the sea level to a boat that is at a horizontal distance of 1.5 km from the lighthouse". A picture (not to scale) may be given as the one on the right. But then, what if the scenario is in 3D?

## A boat with a sail

A classic boat has a main body (hull) and a mast with a main sail. Using the build-in primative objects, there could be some possible boats contructed. In this blog, I used three objects: a SNOUT for the hull, a CYLINDER for the mast, and a 2D PIE for the sail. Of course these objects are scaled and textured with materials and images to be looking like (I hope ) .

## Quartz Molecule

All matter in the world is compounded from basic units of measurements called atoms. Atoms are made up of protons and neutrons, making the nucleus in the centre and electrons, which are much lighter in rings around it. Elements are substances made from only one type of atom, although when different atoms combine, they form compounds, or molecules. In a compound the atoms are being held together with chemical bonds. In this blog, I will be talking about the structure and characteristics of the molecule quartz.

## Sulphuric Acid

Sulphuric acid is a pungent-ethereal, colourless to slightly yellow viscous liquid that is soluble in water at all concentrations. It is highly corrosive, dense and oily and one of the most important of all chemical, prepared industrially by the reaction of water (H2O) with sulphur trioxide (SO3). In different concentrations, the acid is used to manufacture fertilisers, pigments, dyes and detergents as well as in petroleum refining and metallurgical processes. Its most common use is in lead-acid storage batteries. In this blog, there will be a detailed analysis of the use of sulphuric acid, its bonds and characteristics.

Introduction

## Sulfur atom by Grace Dowdle

In this blog post, I will be informing readers about the composition, structure and characteristics of a chosen atom, sulfur, and I will display the 3D model that myself and my partner created.

## NaCl Lattice Blog Entry FINAL (Ryan Gray ASC091C)

By Ryan Gray ASC091C

This model is of a salt crystal lattice, with the chemical formula NaCl. Its different properties allow it to have many uses in society, including as a preservative, flavouring and currency. Salt demonstrates ionic bonding and its structure makes it interesting to model, because the crystal lattice can continue on forever and doesn't have a specific number of atoms like water does, with each water molecule consisting of one oxygen and two hydrogen atoms. For the purposes of this project, I limited my model to a 3x3x3 cube so it could be easily seen. The distance between the atoms was also expanded to allow the bonds to be more clearly viewed.

## Ethane Molecule

Ethane is a compound that is a byproduct of petroleum processing, and can then be processed to create plastics and ethanol. It is a versatile chemical, and it is also found on other planets, not just Earth. This discovery has scientists interested in Ethane. Ethane’s chemical formula is C2H6 as shown in the diagram below. This blog will discuss the properties, composition, characteristics, and structure of ethane, as well as the uses of ethane, and compounds derived from ethane, as ethane is mainly converted into other molecules.
