This interactive resource takes students on a journey of discovery in the energy and mining world. Oresome world contains five games or modules: Coal, Energy, Gas, Low emissions and Mining, and within each of these there are several facilities to explore, such as the Underground mining site, Hydroelectric power station, ...

• TLF-IDL5819

Measure the pH as you gradually add an acid to a base, or vice versa. Predict the change in pH when you mix acids and bases. Notice that the pH drops or rises quickly when the neutralisation point is almost reached. Remember, all acids and bases including the dilute solutions used in this object, can be harmful and should ...

This is a set of student digital activities about states of matter, the particle model and simple chemical equations. It contains a rich array of interactive activities, film clips and notebook questions to assist learning, and is part of a comprehensive curriculum resource that covers Chemical sciences content descriptions ...

• TLF-IDL5818

Measure the pH as you gradually add an acid to a base, and vice versa. Learn how to change pH up or down. Adjust the pH in a swimming pool to ensure the water is safe for people to swim in. For example, return the pH to a suitable level after heavy rain. Remember, all acids and bases including the dilute solutions used ...

• TLF-IDM016610

This resource contains a materials and instruction list and brief explanation for students about the process of burning both ends of a balancing candle. This activity is most likely to be done as a teacher demonstration for safety and classroom management reasons, particularly at primary school level.

• TLF-IDM015807

Why are some metals prized more for jewellery than others? Listen to presenter Bernie Hobbs explain the chemical reaction that affects the look and durability of metals. Using the periodic table and some dazzling computer graphics, Bernie demonstrates why 'oxygen-proof, low-reactivity, transition metals' such as gold keep ...

• TLF-IDM019627

Take a look at cells, and some of their components, starting from the very beginning of life on Earth. Speculate on the origin of the molecules of life and investigate how they combine to create the structure and function of cells.

• TLF-IDM016389

This resource contains a materials and instruction list and brief explanation for students about the process of relighting a candle. This activity is most likely to be done as a teacher demonstration for safety and classroom management reasons, particularly at primary school level. Do this experiment to learn how a candle ...

Some magic tricks, such as disappearing ink or candles that won't blow out, can be explained by chemistry. In this clip, three classroom chemistry experiments demonstrate that some familiar magic tricks rely on acid-base chemical reactions, and the properties and behaviour of gases. Watch closely if you've ever wanted to ...
