Everyday Materials, Properties, Uses, Reversible change for Kids
(scroll this section to read all)
This Science topic is all about materials that you come across in your everyday life. You will learn about their properties and the uses they are put to largely because of those unique properties. In addition reversible changes are looked at too as well as the differences between chemical and physical changes.
This scientific information is useful to know about so that you can make sense of why certain materials are used for specific duties and this can help in general life as well as in variety of occupations including engineering, chemistry and even inventions.
Always follow Safety Rules and consult a responsible adult before attempting any sort of experimentation, testing or cooking etc. All safety hazards should be fully understood and any necessary precautions put in place beforehand.
Once you understand the basics of 'Everyday materials,Properties and Uses', you should be able to:
- Group materials together based on properties gathered from fair tests (e.g. magnetism, hardness, electrical conductivity, thermal conductivity, solubility etc.)
- Understand about particles at an atom and element level
- Conservation of mass during changes
- Understand more about dissolving of some materials and recovery from the solution.
- Understand about reversible changes (e.g melting, evaporating, dissolving and filtering)
- Understand about filtration and separation of solids from liquids
- Propose suitable materials to solve a particular problem
For information on Gases, Liquids and Solids , see our article here on 'STATES OF MATTER'.
For information on formation of new materials , see our article here on 'CHANGES THAT FORM NEW MATERIALS'.
If you want to learn more about properties, take a look of some of the great resources we have put together below including games, quizzes, videos and revision notes.
Put everyday objects (such as a biscuit, a saucepan, a newspaper, a sugar cube, a rain hat, a cutting (chopping) board, a plastic bag and a scarf) into a testing machine and see if they are waterproof or bendy by clicking on the levers. Once you have finished see if you can sort the objects into groups (waterproof & bendy, waterproof &....Read More
There are 3 levels to play. In the "Medium Level" game you must help Max to sort the objects in the shipwreck. Collect the shiny objects and objects with certain properties (in particular ones that float, objects you can see through, smooth objects and soft objects). In the "Hard Level" you must help Max collect objects made from certain....Read More
There are 3 levels to play. In the Medium Level game you must help Molly to see which objects will dissolve in her cauldron of water (sugar cube, book of spells, salt, pumpkin and crystal ball). In the Hard Level you must help Molly make a magic potion by predicting which of three possible objects will dissolve in water. In the Really....Read More
Group all the objects by grabbing each one on the conveyor belt and placing it into 'Wood', 'Glass', 'Metal' or 'Rubber'. Objects include a door, a knife, a magnet, a window, a balloon, a tyre, a spoon and an elastic band. Then you are asked to think about why the objects are made in their respective materials and also which two groups....Read More
Put everyday materials (such as metal, paper, fabric, rubber, glass and plastic) into a testing machine and see if they are waterproof, transparent, flexible or strong by clicking on the levers. Once you have finished, go to the workshop and see if you can decide which are the best materials to make a car tyre (tire), saucepan, towel,....Read More
The dangerous Androvax wants to destroy the Earth after rebuilding his spaceship which has crash landed on Earth. Trick him into building his spaceship out of the wrong materials. First test all your materials (wood, glass, plastic, metal and wool) with various tools (mallet, drill, hose and torch) to see what properties they all have.....Read More
Select 5 balls from the 9 available (baseball, basketball, bouncy ball, football, golf ball, handball, squash ball, table tennis ball and tennis ball). Read up on their material properties (for example a golf ball is made from a variety of plastics with a soft compressible core and a tough casing) then, choose a height to drop them all....Read More
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
Help the Scan Bot search the house to find everyday materials. The Scan Bot must find all of the wooden objects, all of the metal objects, all of the glass objects and all of....Read More
This activity goes through some basic information about atoms and elements. It explains that everything you see is made from atoms and a number of atoms make an element. Elements are listed in the periodic tables are either metals or non-metals. Metals tend to sink, conduct electricity and tend to be solids whereas non-metals tend to....Read More
Start off with Silicon, Iron and Carbon as raw materials. Choose one to modify and select two of the following: heat it, beat it or treat it. Then click the start button to see what the machine makes. Then watch informative videos and read interactive notes about the topic. For example if you choose iron to heat and beat then there is....Read More
Use the Universal Comparison Device to compare the materials used in a Formula 1 Racing Car to those in a normal Household Car. You can strip down the layers of the car and compare one easily to the other. For example, the brake pads in a formula 1 car are made from a carbon-carbon composite material (graphite fibres/fibers in a carbon....Read More
Play this electronic version of Top Trumps but with a twist. These cards are all about different types of woods. Each wood has lots of properties and you can play either against a friend or against a computerised opponent. Wood Properties you can choose include density, bending strength, shear strength, stiffness, strength to weight,....Read More
Strip down a camera and look at each component part and see what it is made of. Parts to check out are the Lens Cap, Lens Casing, Lens, Camera Body, Pentaprism, Wind on mechanism, Mirror, Eyepiece, Shutter and the Film.
