Changes that form new materials for Kids
(scroll this section to read all)



Another great Science topic to learn about is 'Changes that form new materials'. Many chemical changes including baking, burning or oxidisation of materials are usually irreversible which means the change is permanently made. Another example is the reaction of acid (e.g. vinegar / acetic acid) on bicarbonate of soda which gives off carbon dioxide. See our links below for a great fun video experiment on this.

Learning all about changes that form new materials can really help you understand how things work and is useful to all manner of careers including chemistry careers, engineering careers, becoming a chef, working in textiles and even becoming an inventor! Spencer Silver invented the glue for Sticky Notes which have become a household and business hit so a good knowledge of how things can be changed is a great business asset. And it's fun!

Of course it is vitally important to follow all Safety Rules and consult a responsible adult before doing any cooking, baking or lab-type experiments or reactions. These changes can be dangerous if not done properly and you need to fully understand all of the safety hazards and take any necessary precautions before carrying them out.

Once you understand the basics of 'Changes that form new materials', you should be able to:

  • Understand more about oxidation
  • Understand more about reversible and irreversible changes
  • Have a good idea about how to separate mixtures
  • Understand the difference between elements, compounds and mixtures
  • Understand more about corrosion and rusting, what causes it and some methods of preventing rusting and corrosion

Obviously there are lots of chemical equations and calculations that could be shown with much of this topic and some of the more common ones are discussed! But early on in your science career is it good enough to know how these new materials are formed and whether they are reversible or irreversible.

For information on material properties, see our article here on 'EVERYDAY MATERIALS, PROPERTIES, USES & REVERSIBLE CHANGE'.

For information on Gases, Liquids and Solids , see our article here on 'STATES OF MATTER'.

We have put together a great collection of games, notes and activities that can really help you learn whilst having fun and playing. Play the games, try the activities and have a go at the Quizzes. Before you know it, you'll have a great idea how new materials might be formed.

There are 3 levels to play. In the Medium Level game you must help Max prepare food in the kitchen like making dough square, making pizza dough large and thin, making orange juice from an orange, choosing the correct ingredient for ketchup, making pasta twirly and making dough long like French bread. In the Hard Level you must help Max....Read More

 


"Changes in Materials" Game ages 7 - 11

"Changes in Materials" Game

You need to use your knowledge of materials and reversible and irreversible changes and stop SKUL's agent from vaporizing Beg Ben in London using the Crystal of St. Helena. You need to find the Crystal by using one of 6 tools (air blower, sieve, solvent spray, fire tool, freeze tool and magnifying glass) to change the various items in....Read More

 


"All Rusted Up" Video Animation ages 7 - 11

"All Rusted Up" Video Animation

First sign up for a free account then watch this fun animated video about a girl's bike which has corroded and rusted up. This happened because she left her bike outside exposed to the elements all winter and the metals reacted with the moisture and oxygen in the air to produce rust. Her father....Read More

 


"How Stuff Changes" Video ages 7 - 11

"How Stuff Changes" Video

Watch this video showing how new materials are made from non-irreversible changes, for example chemical reactions or burning. The first part of the video shows the Dessehra Hindu Festival where fire is used to produce non-reversible chemical changes by burning the ten-headed King Ravan (with fireworks included!). The second part of the....Read More

 


"Muffins with Smarties on Top" Cooking Game ages 9 - 12

"Muffins with Smarties on Top" Cooking Game

Have a go at this great game where you can bake and "eat" beautiful vanilla and chocolate muffins! Your ingredients include butter, sugar, two eggs, flour, sugar, cocoa powder, milk and golden syrup. There is also, of course, smarties or other chocolate candy treats! This cooking game lets you observe....Read More

 


"Reversible and Irreversible Changes" Game ages 10 - 11

"Reversible and Irreversible Changes" Game

Put everyday substances (such as a raw egg, ice, sugar, sand, salt, coffee and flour) into a beaker of water, mix, try to dissolve and see if it can be reversed by heating, cooling or....Read More

 


"Acids, Bases and Metals" Activity ages 11 - 14

"Acids, Bases and Metals" Activity

In this interactive animation activity, you learn about acids, bases, the neutralising reactions between them pH. Also the use of litmus papers and universal indicator are described. The pH scale runs from 0 - 14 where zero is very acidic and 14 is very alkaline. A pH of 7 indicates a neutral solution. It is important to understand that....Read More

 


"Chemical and Material Behaviour" Activity ages 11 - 14

"Chemical and Material Behaviour" Activity

In this interactive animation activity you are shown how you can make new materials. For example heating the elements iron and sulphur (sulfur) produces a completely new compound called iron sulphide (iron sulfide). Fusing hydrogen and oxygen atoms releases lots of energy in an exothermic reaction creating water. Then learn about....Read More

 


"Chemical Reactions" Revision Notes ages 11 - 16

"Chemical Reactions" Revision Notes

The notes explain how chemical reactions between elements form compounds (which are elements bonded together by sharing or transferring electrons). Covalent Bonds are formed when atoms share a pair of electrons. Ionic bonds are formed when atoms gain or lose electrons and an ionic bond is the attractive force between particles of an....Read More

 


"Reaction Action Combustion and Gasification" Game with cool sounds ages 11 - 16

"Reaction Action Combustion and Gasification" Game with cool sounds

You need to register for this free game and then when you start it, various reactions are happening in the lab. You must capture the products of combustion with the correct sponge without making too much waste. Hydrogen and oxygen are combined at the beginning to make water, then methane is burnt to produce water, carbon dioxide and....Read More
