1A student wants to find out if the temperature of water affects how fast salt dissolves. Which of the following is a testable hypothesis for this investigation?
A.Salt dissolves faster in hot water than in cold water.
B.How much salt can dissolve in a cup of water?
C.Salt dissolves because water molecules pull it apart.
D.Does hot water dissolve salt?
Explanation: A hypothesis is a clear, testable prediction about the relationship between two variables. The statement that salt dissolves faster in hot water than in cold water is a testable hypothesis because it makes a direct prediction about how the temperature of water affects the rate of dissolving. The other options are questions or general explanations rather than testable predictions.
2In an experiment investigating how the amount of fertilizer affects the height of bean plants, what is the independent variable?
A.The height of the bean plants
B.The type of bean plants used
C.The amount of fertilizer added
D.The volume of water given daily
Explanation: The independent variable is the factor that the investigator intentionally changes or manipulates in an experiment. In this investigation, the amount of fertilizer is changed to observe its effect. The plant height is the dependent variable, while the type of plants and volume of water are controlled variables.
3A student measures the time it takes for a candle to burn down at different room temperatures. What is the dependent variable in this experiment?
A.The room temperature
B.The time taken for the candle to burn down
C.The size of the candle used
D.The brand of the candle
Explanation: The dependent variable is the factor that is measured or observed in response to changes in the independent variable. Here, the student measures the time it takes for the candle to burn down. The room temperature is the independent variable, and the candle size and brand are controlled variables.
4Why is it important to control variables that are not being tested in an experiment?
A.To make the experiment run faster
B.To ensure that the results are due only to the independent variable
C.To guarantee that the hypothesis is proved correct
D.To allow more than one variable to be changed at the same time
Explanation: Controlling variables ensures a fair test by keeping all factors constant except the one being investigated. This allows the researcher to be confident that any observed changes in the dependent variable are caused solely by the independent variable. Changing multiple variables at once makes it impossible to determine which one caused the effect.
5When reading the volume of a liquid in a graduated cylinder, where should a scientist's eye level be aligned?
A.At the top edge of the liquid curved upward
B.At the bottom of the meniscus at eye level
C.Slightly above the liquid level looking down
D.Slightly below the liquid level looking up
Explanation: Water curves slightly in a glass container, forming a shape called a meniscus. To get an accurate reading, your eye must be level with the bottom of this curve. Looking from above or below introduces parallax error, which leads to inaccurate measurements.
6Which of the following pieces of laboratory apparatus is most appropriate for measuring the mass of a small rock?
A.A measuring tape
B.A triple-beam balance
C.A graduated cylinder
D.A thermometer
Explanation: Mass is the measure of the amount of matter in an object, and a balance (such as a triple-beam or electronic balance) is used to measure it. A measuring tape measures length, a graduated cylinder measures liquid volume, and a thermometer measures temperature. Therefore, the balance is the correct tool.
7A student needs to measure exactly 10.0 degrees Celsius. Which laboratory apparatus must they use?
A.A Bunsen burner
B.A laboratory thermometer
C.A measuring cylinder
D.A stopwatch
Explanation: Temperature is measured in degrees Celsius (°C) using a thermometer. A Bunsen burner provides heat but does not measure temperature. Measuring cylinders measure volume, and stopwatches measure time.
8Which unit is most commonly used in the laboratory to record the volume of a liquid in a test tube?
A.Gram (g)
B.Milliliter (mL)
C.Centimeter (cm)
D.Degrees Celsius (°C)
Explanation: Volume is the amount of space occupied by a substance, and milliliters (mL) is the standard metric unit used for liquid volumes in school labs. Grams measure mass, centimeters measure length, and degrees Celsius measure temperature.
9What is the correct and safe way to smell a chemical substance in a science laboratory?
A.Place your nose directly over the container and inhale deeply.
B.Use your hand to gently wave the vapors toward your nose.
C.Ask another student to smell the chemical first.
D.Heat the chemical first so the smell becomes stronger.
Explanation: Directly inhaling chemical vapors can damage your nasal passages and lungs. The safe method is wafting, where you use your hand to gently fan the vapors toward your nose from a safe distance. Heating unknown chemicals or smelling them directly is highly dangerous.
10If a dilute acid splashes onto your skin during a laboratory experiment, what is the very first action you should take?
A.Apply a bandage to cover the area.
B.Rinse the affected skin immediately with plenty of running water.
C.Wipe the skin clean with a dry paper towel.
D.Neutralize the acid by pouring a strong base over it.
Explanation: The immediate first-aid response for any chemical splash on the skin is to flush the area with copious amounts of clean, running water for several minutes. This dilutes and washes away the chemical, preventing further damage. You must also notify your teacher immediately after starting the rinse.

About the CCSLC Integrated Science Exam

The Caribbean Certificate of Secondary Level Competence (CCSLC) Integrated Science syllabus is designed to provide secondary school students with the scientific literacy and inquiry skills needed for everyday life and further study. It covers five core modules: Working Like a Scientist, Investigating Matter, Understanding Life, Focusing on Me, and Exploring Energy. The assessment consists of a School-Based Assessment (SBA) worth 50% (composed of five module assessments) and a written external examination of 50 multiple-choice items contributing 50%. This practice exam provides 100 original questions covering the breadth of the syllabus to help candidates build confidence and mastery.

Exam sponsor: Caribbean Examinations Council (CXC). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

CCSLC Integrated Science: Suggested Study Strategy

1Review laboratory safety symbols and the scientific method; understand how to identify independent, dependent, and controlled variables in any given experiment.
2Learn to distinguish between physical and chemical changes. Remember that chemical changes produce new substances, whereas physical changes only change the state or appearance.
3Compare plant and animal cells side-by-side. Make sure you know which structures (like cell walls and chloroplasts) are only found in plant cells.
4Trace the path of food through the digestive system and air through the respiratory system. Understand the roles of key organs and how they support life.
5Practice calculating speed (distance divided by time) and work done (force times distance) to handle basic quantitative questions.
6Understand the differences between series and parallel circuits, especially how bulb brightness and current flow change when a switch is opened or closed.
