Since the earliest times, humankind has had a close association with clay. From use as a building material, in pottery, for treating human digestive ailments to a multitude of industrial uses ...
Water in the Earth system is influencing all aspects of life on Earth. Pathways, storage, transfers and transformations have an effect on the global climate and human welfare. Within this ...
Use this timeline to explore how humans have relied on fossil fuels in the past and how we are looking for, and using, new energy sources. 200,000 BC – Fire used Records of the first controlled ...
Energy comes from many sources, and to describe these sources we use two terms: renewable and non-renewable. Non-renewable energy resources cannot be replaced – once they are used up, they will ...
Solar energy is transformed into other energy forms for our use on Earth – energy for food (chemical energy), electrical energy and heat energy. Food Solar energy (sunlight) is crucial for our ...
A water catchment is an area of land and the water that collects and moves through it. A catchment is often bordered by hills or mountains. The water enters via precipitation (rain or snow) and ...
This animated video demonstrates the formation of hydrocarbons over millions of years in the depths of the Earth. Oil and gas forms in sedimentary ocean basins. Dead plankton (organic plant and ...
In pre-human times, almost all of New Zealand was covered in forest, with the exception of high mountain areas. Māori settlers began to clear forest, and by the time the first Europeans arrived ...
Renewable energy is fuel that comes from a source that can be replenished in a short amount of time. This includes solar, wind, water, geothermal power and bioenergy. While renewable energy ...
Bioplastics are plastic materials that are derived from biological materials. Currently, petrochemical-based plastics make up 99% of the plastics market. However, production of bioplastics is ...
Mussels are filter feeders. They draw in seawater and filter out phytoplankton and sediments, cleaning the water as they go. This 25-second video is a before and after display of murky seawater ...
This interactive highlights the critical role temperature plays in the world of ceramics.
Bioceramics are ceramic materials specially developed for use as medical and dental implants. They are usually used to replace hard tissue in the body like bone and teeth. Common bioceramics are ...
Rivers and Us is a Waikato Regional Council (WRC) initiative to help teachers, students and communities investigate the water in their local area. It explores how people use water and the effects ...
Discover information and hands-on activities about the water cycle.
It is important for students to understand how a specific task and idea fits within and contributes to their learning in the longer term and across a whole sequence of tasks. Learning may be ...
Scientists generally agree that the amount of water on Earth is finite, and that the water cycle constantly recycles water through the Earth’s systems. But how long does this take? How long does ...
This timeline provides a look at some of the historical aspects in finding out the age of the Earth. Find about more the developments in how geologists find out the ages of rocks and fossils ...
Composite materials (composites) are made when two or more materials with different properties are combined to produce a new material. The physical and chemical properties of each of the ...
