SCIENCE REVISION CARDS For KS3 and Common Entrance I recommend printing the following pages onto card and cutting them into 4 equal pieces. They will then fit into a file box for revision purposes. Many children put the cards that they need to learn in a small photo album which is easy to carry around. Parents enjoy these cards as they can use them to test their children s knowledge of a subject.
Relights a glowing splint Soluble ---------can dissolve Insoluble -------can not dissolve Saturated ------nothing more can dissolve Suspension------some bits do not dissolve Lit splint Squeak Squeaky pop (eg muddy water) Turns lime water cloudy ph Scale Metal Hydroxide + Hydrogen STRONG ACID NEUTRAL STRONG ALKALI Metal Oxide Salt + Hydrogen HYDROCHLORIC ACID produces CHLORIDE SALTS SULFURIC ACID SULFATE SALTS NITRIC ACID NITRATE SALTS
--- Movement --- Respiration --- Sensitivity --- Nutrition --- Excretion --- Reproduction ---Growth Getting rid of waste products Anther holds pollen Found in every cell Smaller than chloroplasts & nucleus

Turns food into Energy Self-pollination- pollen transferred from Stamen to stigma on same plant Wind pollination insect pollination Pollen sticky stigma ovary becomes fruit Sun Rain CO 2 Energy WOW Warmth, Oxygen Water explosion animals birds wind Strong Shiny Heat Electricity Alarm m Metals make a ringing sound when hit- they are SONOROUS Conductor Oxides formed when metals react with oxygen Malleable/ Ductile Easy to shape Metals are elements & in Periodic Table VERY REACTIVE FAIRLY REACTIVE NOT VERY REACTIVE NOT AT ALL REACTIVE Professor POTASSIUM Smith SODIUM Called CALCIUM Me MAGNESIUM A ALUMINIUM Zombie ZINC I IRON Left LEAD Class COPPER Sucking SILVER Gum GOLD
BAA Energy cannot be made or destroyed, only transferred Sound Heat Electrical Elastic (mechanical potential) Potential (gravitational potential) Chemical Movement Light Nuclear P S C M A Z I L C S G A metal higher in the series will displace a less reactive metal from its compound eg: Potassium + Copper Sulphate Potassium Sulphate + Copper Magnesium + Copper Oxide Magnesium Oxide + Copper BUT Sodium Oxide + Copper NO CHANGE PROTEIN CARBOHYDRATE FATS Balanced Forces = no movement Unbalanced forces= change of speed/ direction VITAMINS MINERALS Calcium teeth/bones Iron blood WATER 75% of our body. FIBRE FORCES MAKE OBJECTS: Speed up Slow down Change direction Turn Change shape eg twisting Air resistance
ee ee ee ee ee FREQUENCY (Hertz- Hz) lots of vibrations per second= high frequency a high pitch sound few vibrations per second= low frequency - low pitch sound. Mooo NOTE: BASES are the OXIDES & HYDROXIDES of metals Sulfuric Acid SULFATE salt Hydrochloric Acid CHLORIDE salt Nitric Acid NITRATE salt AMPLITUDE (Amps) A tall wave is a loud sound A short wave is a soft sound Atom Element Mixture Compound When 2 or more different atoms join together they form compounds LAW OF REFLECTION LAW OF REFRACTION Angle of Incidence= Light going to a more dense Angle of Reflection medium bends to the normal Light leaving it bends away from the normal Atom Element
Battery/cell Bulb Switch Ammeter WHITE CELLS Kill invading microbes PLASMA- liquid containing salt, sugar, proteins PLATELETS-form clots to stop bleeding Variable resistor Voltmeter Motor Smallest part of an element. Lots of the same atoms make an element. When atoms join together they form molecules A substance only made up of one type of atom A substance made up of two or more elements A mixture of different elements or compounds (can be separated) PARTICLES Tightly packed In fixed position Packed closely Move around (in liquid) Far apart Move around quickly (anywhere)
