The Common Entrance exam has 2 levels. Level1 is a single 60 minute paper worth 80 marks.
Level 2 is three 60 minute papers, physics, chemistry and biology, worth 40 marks each.
Students will either take the level 1 paper or the three level 2 papers. Level 1 is a mixture of physics chemistry and biology and is a little easier then level 2.
Candidates sitting the level 2 papers will not be required to take the level 1 paper.
Talk to your science teacher if you are unsure or have any worries.
Know the terms solvent, solute, solution, soluble, insoluble and saturated.Know that when a solid dissolves in a liquid then a solution is formed.Knowhow to show the effect of different temperatures and different solutes on the rate of dissolving.Know that Ethanol and propanone are alternative solvents to water
Knowledge of filtration, distillation, evaporation and chromatography.
Be able to draw a diagram of the apparatus used
Know how to separate two solids eg chalk from salt
Knowledge of filtration to remove insoluble solids from a suspension
Simple distillation to obtain a solvent from a solution eg fresh water from blue ink or seawater. (how to prevent suck-back when distilling) Evaporation to obtain a solute from a solution Paper chromatography to separate coloured dyes.
Fractional distillation to recover ethanol from wine or beer
Limestone is made from calcium carbonate
Useful as a building material. Easily cut but weathers easilyWhen limestone is heated it decomposes forming carbon dioxide and leaving agricultural lime (calcium oxide)
Limestone reacts with hydrochloric acid to form carbon dioxide gas. Carbon dioxide dissolves in rain water making the rain acidic which attacks the limestone.
Measurement of and units for distance, mass and time.
The period of a pendulum as an example of measurement
Measurement of density Density = mass ÷ volumeunit of density = kg/m3 or g/cm3
Calculate density of solid objects (regular and irregular shape)
(use displacement of water to find volume of irregular solid)
Calculate density of liquids
That air has mass and we can calculate its density
Reflection. Angle of incidence = angle of reflectionLight changes direction when it meets a boundary Refraction .
Dispersion. How a prism disperses white light similar to a rainbow.Comparing speed of light and sound
Amplitude, volume. Frequency and pitch.
How to study of a habitat: measurement of animal or plant populations
Using a quadrat
Study of an animal and plant.
Energy flow along food chain.
Comparison between sexual and asexual reproduction
How to measure a physical factor in the environment like temperature or light intensity.
How population size is effected by predation or competition
The importance of conserving habitats
How to use a key to identify an animal or plant using its features
Environmental and inherited causes of variation
Discontinuous and continuous variation
The carbon cycle and its role in maintaining a balance between photosynthesis and respiration
Know how to carry out a CONTROLLED experiment (Carry out two experiments, changing one and not the other [the control])
Understand how to carry out a fair test and realise the importance of a fair test. (so the results can be compared with accuracy). Change only one variable (the independent variable) and measure the dependent variables. Keep all other variables the same)
Know the names on apparatus used to measure. Metre rule, stopwatch, spring balance, top pan balance, bourdon gauge, measuring cylinder, beaker
Know the units on apparatus used to take measurements
Know the names and use of apparatus used in chemistry and biology
Correct use of tables and graphs
Labelling graphs with correct units
Using the correct type of graph (line or bar graph)
Some example investigations
Showing how effective an insulation is at keeping water warm.
Showing that light intensity controls the rate of photosynthesis.
Showing how the resistance of a wire increases with length
Showing how the solubility of a solvent increases with temperature
Showing the presence of starch in a leaf,.
Measuring the speed of a ball rolling down a slope
