SCIENCE REVISION CARDS For KS3 and Common Entrance

Transcription

1 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.

2 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

3 --- Movement --- Respiration --- Sensitivity --- Nutrition --- Excretion --- Reproduction ---Growth Getting rid of waste products Anther holds pollen Found in every cell Smaller than chloroplasts & nucleus

4 DISTANCE SPEED TIME FORCE PRESSURE AREA X Dad Speeded Today P F A Fat People Allowed Separates dyes MOMENT FORCE DISTANCE m=moment of force (turning effect) F M D My Fat Daddy MASS DENSITY VOLUME D M V Massive Dead Vampire Separates liquids from solids that are soluble Separates liquids with different boiling points Moment = Force X Distance from pivot 3 x 4 =12 4 x 3 = (RUST) 3K 4K This will balance 5 x 2 = 10 2 x 6 = To absorb any water 2K 6K This will NOT balance

5 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

6 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

7 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

8 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)
