Here are our 2023 BECE Integrated Science Questions with answers for students to study with. We challenge you to go through all the questions and master them.
Ten integrated science questions with short answers:
- What is the difference between an element and a compound? Answer: An element is a substance made up of only one type of atom, while a compound is a substance made up of two or more different types of atoms chemically bonded together.
- What is the process of photosynthesis? Answer: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll and release oxygen as a by-product.
- What is the function of the mitochondria in a cell? Answer: The mitochondria are the “powerhouses” of the cell, responsible for generating energy in the form of ATP through cellular respiration.
- What is the difference between a solid, liquid, and gas? Answer: A solid has a fixed shape and volume, a liquid has a fixed volume but no fixed shape, and a gas has neither a fixed shape nor a fixed volume.
- What is the difference between an acid and a base? Answer: Acids are substances that release hydrogen ions (H+) in water, while bases are substances that release hydroxide ions (OH-) in water.
- What is the difference between a renewable and non-renewable resource? Answer: Renewable resources can be replenished naturally over time, such as wind or solar power, while non-renewable resources cannot be replenished, such as fossil fuels.
- What is the function of white blood cells in the body? Answer: White blood cells are part of the immune system and help to fight infections and diseases by recognizing and destroying harmful pathogens.
- What is the difference between a physical and a chemical change? Answer: A physical change is a change in the physical properties of a substance, such as its shape or state of matter, while a chemical change is a change in the chemical composition of a substance, such as the formation of a new substance.
- What is the difference between a prokaryotic and eukaryotic cell? Answer: Prokaryotic cells are smaller and simpler in structure, lacking a true nucleus or membrane-bound organelles, while eukaryotic cells are larger and more complex, containing a nucleus and various organelles.
- What is the difference between weather and climate? Answer: Weather refers to the short-term conditions of the atmosphere, such as temperature and precipitation, while climate refers to the long-term patterns of weather in a particular region.
Ten integrated science calculation questions with short answers:
- What is the formula for calculating density? Answer: Density = Mass / Volume
- What is the equation for calculating force? Answer: Force = Mass x Acceleration
- If a car travels at a speed of 60 km/h for 2 hours, how far does it travel? Answer: Distance = Speed x Time Distance = 60 km/h x 2 hours = 120 km
- What is the formula for calculating work? Answer: Work = Force x Distance
- If a student travels a distance of 10 km in 2 hours, what is their average speed? Answer: Average speed = Distance / Time Average speed = 10 km / 2 hours = 5 km/h
- What is the equation for calculating power? Answer: Power = Work / Time
- If a bicycle wheel has a diameter of 60 cm, what is its circumference? Answer: Circumference = π x Diameter Circumference = π x 60 cm = 188.5 cm
- If a container holds 500 mL of water, what is its volume in liters? Answer: 1 liter = 1000 mL, so the volume is 0.5 liters.
- What is the equation for calculating kinetic energy? Answer: Kinetic energy = (1/2) x Mass x Velocity^2
- If a ball has a mass of 0.5 kg and is dropped from a height of 10 meters, what is its potential energy just before it hits the ground? Answer: Potential energy = Mass x Gravity x Height Potential energy = 0.5 kg x 9.8 m/s^2 x 10 m = 49 J.
Ten true or false integrated science calculation questions with short answers:
- True or False: The pH scale ranges from 0 to 14, with a pH of 7 being neutral. Answer: True.
- True or False: The density of an object is affected by its volume. Answer: True.
- True or False: A force can be defined as the rate of change of an object’s velocity. Answer: False. A force can be defined as an influence that causes an object to undergo a change in motion, but it is not necessarily the rate of change of velocity.
- True or False: The formula for calculating power is Work / Time. Answer: True.
- True or False: The net force acting on an object is equal to its mass multiplied by its velocity. Answer: False. The net force acting on an object is equal to its mass multiplied by its acceleration.
