Sample NGSA Science Practice Questions

Try these sample questions to test your NGSA Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which type of teeth is primarily used for biting and cutting food into smaller pieces?
A.Canines
B.Incisors
C.Molars
D.Premolars
Explanation: Incisors are the chisel-shaped teeth at the front of the mouth used for biting and cutting food. Humans have eight incisors in total, four at the top and four at the bottom.
2Which organ is the main pump responsible for circulating blood throughout the human body?
A.Lungs
B.Heart
C.Kidneys
D.Liver
Explanation: The heart is the muscular organ that pumps blood through the blood vessels of the circulatory system. It provides oxygen and nutrients to the body while assisting in the removal of metabolic wastes.
3Which organ removes carbon dioxide, a waste product of respiration, from the body?
A.Kidneys
B.Skin
C.Lungs
D.Large intestine
Explanation: The lungs are excretory organs that remove carbon dioxide and water vapor from the body when we exhale. Carbon dioxide is produced during cellular respiration and must be removed to maintain blood balance.
4How many sets of teeth do humans naturally grow during their lifetime?
A.One set
B.Two sets
C.Three sets
D.Four sets
Explanation: Humans naturally grow two sets of teeth in their lifetime: temporary (milk) teeth and permanent teeth. The milk teeth are replaced by permanent teeth during childhood and adolescence.
5Which part of the skin is responsible for producing sweat to help cool the body?
A.Sweat glands
B.Hair follicles
C.Blood capillaries
D.Pores
Explanation: Sweat glands produce sweat, which is carried to the skin surface via ducts. As the sweat evaporates from the skin, it absorbs heat energy, thereby cooling the body down.
6Which food group is primary source of energy for the human body to perform daily activities?
A.Proteins
B.Vitamins
C.Carbohydrates
D.Minerals
Explanation: Carbohydrates are the body's main energy source, broken down into glucose to fuel cells, tissues, and organs. Starchy foods like cassava, sweet potatoes, and rice are rich in carbohydrates.
7What is the main function of blood capillaries in the human circulatory system?
A.To pump blood to the lungs
B.To prevent backflow of blood
C.To exchange gases and nutrients between blood and body cells
D.To carry blood away from the heart under high pressure
Explanation: Blood capillaries are tiny, thin-walled blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and wastes takes place between the blood and the surrounding body tissues.
8Which type of teeth is pointed and used primarily for ripping and tearing tough food like meat?
A.Incisors
B.Premolars
C.Canines
D.Molars
Explanation: Canines are the pointed, sharp teeth located next to the incisors. They are adapted for tearing food apart, which is why carnivores have very prominent canine teeth.
9How do the kidneys perform their function in the human excretory system?
A.They produce bile to break down fats
B.They filter waste products from the blood to form urine
C.They exchange oxygen and carbon dioxide
D.They release sweat to regulate body temperature
Explanation: The kidneys act as filters that remove urea, excess salts, and water from the bloodstream. This filtered waste forms urine, which is transported to the bladder and excreted from the body.
10What effect does regular exercise have on the human heart?
A.It decreases the volume of blood in the body
B.It strengthens the heart muscle and improves blood circulation
C.It weakens blood vessels
D.It stops the heart from beating too fast during stress
Explanation: Regular physical exercise strengthens the cardiac muscle, allowing the heart to pump blood more efficiently with each beat. This improves circulation and overall cardiovascular health.

About the NGSA Science Exam

The National Grade Six Assessment (NGSA) Science Exam is Guyana's national examination for Grade 6 pupils, used to determine placement into secondary schools. Administered by the Ministry of Education's National Centre for Educational Resource Development (NCERD), the assessment evaluates primary school students on the consolidated Science curriculum. The exam features a 40-question multiple-choice Paper 1 and a constructed-response Paper 2. This 100-question practice bank is designed to mirror the style and content of the official NGSA Science Paper 1, testing students across plant/animal biology, human systems, matter, space, weather, energy, forces, and simple machines, with detailed answer explanations.

Assessment

The Science exam is split into two papers: Paper 1 is a 40-item multiple-choice paper, and Paper 2 is a written paper requiring structured/constructed answers. Marks from both papers are combined and scaled for ranking.

Time Limit

Paper 1 allows approximately 1 hour and 10 minutes (70 minutes) of writing time. Paper 2 allows 45 to 60 minutes.

Passing Score

There is no fixed pass mark. Pupils' combined scaled marks across all four subjects are ranked nationally to determine placement in national, regional, or community secondary schools.

Exam Fee

There is no examination fee. The NGSA is a national public assessment administered free of charge to registered Grade Six pupils. (Ministry of Education, Guyana (National Centre for Educational Resource Development))

NGSA Science Study Tips from Top Performers

1Study diagram labels carefully, as the NGSA often asks students to identify parts of the human heart, respiratory system, flower, seed, or electrical circuits.
2Understand the functions of different teeth (incisors, canines, molars) and seed parts (testa, cotyledon, radicle, plumule) rather than just memorising the names.
3For simple machines, practice identifying the positions of the fulcrum, load, and effort to quickly classify levers as first, second, or third class.
4Learn the difference between chemical and physical changes: physical changes are usually reversible (like melting ice), while chemical changes form new substances and are irreversible (like burning wood).
5Read through Guyana Ministry of Education 'Consolidated study notes' and consolidated curriculum guides for Science to make summary notes.

Frequently Asked Questions

What is the format of the NGSA Science Exam?
