Sample Year 10 Science questions

These sample questions are visible on the page before login. They show Year 10 genetics, evolution evidence, particle models, force diagrams, Earth systems, and inquiry graphs before opening the demo.

Year 10 Science Genetics and inheritance hard inheritance diagram

1. The diagram shows a pair of chromosomes before a cell divides to make gametes. Which statement best explains why each gamete receives one allele for the trait?

Choices

The allele pair separates during meiosis.
Both alleles move into every gamete.
The DNA code changes into a new allele.
Chromosomes stop carrying genes in gametes

Explanation:

Homologous chromosomes separate in meiosis, so each gamete receives one chromosome from the pair and therefore one allele for the trait.

Year 10 Science Evolution evidence hard selection graph

2. A population has light and dark beetles. The graph shows the percentage of dark beetles after several generations in a polluted habitat. Which conclusion is best supported by the trend?

Choices

Dark beetles became more common because they had a survival advantage.
Light beetles became more common in every generation.
The beetle population stopped reproducing after generation 2.
The graph proves every dark beetle survived.

Explanation:

The line rises from 20% to 68%, so dark beetles increased. In this habitat, the data supports selection favouring dark beetles rather than an equal random change.

Year 10 Science Chemical reactions hard particle model

3. The particle model shows methane reacting with oxygen to form carbon dioxide and water. Which statement shows conservation of atoms?

Choices

The same numbers of C, H and O atoms appear before and after the reaction.
The products contain fewer oxygen atoms than the reactants.
Atoms are destroyed when the flame releases energy.
The carbon atom turns into hydrogen atoms.

Explanation:

A balanced reaction rearranges atoms. CH4 + 2O2 forms CO2 + 2H2O, so there is 1 C, 4 H and 4 O on each side.

Year 10 Science Motion and forces hard force diagram

4. A trolley is pushed to the right. The force diagram shows a 12 N push to the right and 5 N friction to the left. What is the net force on the trolley?

Choices

7 N to the right
17 N to the right
7 N to the left
5 N to the left

Explanation:

Opposing forces subtract: 12 N - 5 N = 7 N. The larger force points right, so the net force is 7 N to the right.

Year 10 Science Earth systems hard systems diagram

5. The flow diagram shows increased greenhouse gases leading to greater heat trapping and warmer ocean surface water. Which link best explains why coral bleaching risk increases?

Choices

Warmer water stresses coral and causes algae loss.
Greenhouse gases directly turn coral white without heat stress.
Cooler water always increases bleaching risk.
Bleaching risk is unrelated to ocean temperature.

Explanation:

The model links higher greenhouse gases to heat trapping and warmer water. Coral bleaching risk rises because heat stress can cause corals to lose the algae they depend on.

Year 10 Science Science inquiry hard inquiry graph

6. Students tested how nitrate concentration affected algal cell density. The bar chart shows density at 0, 5, 10 and 15 mg/L nitrate. Which concentration gave the highest algal density?

Choices

10 mg/L
0 mg/L
5 mg/L
15 mg/L

Explanation:

The tallest bar is at 10 mg/L. The 15 mg/L bar is lower, so more nitrate did not keep increasing growth in this dataset.

For parents comparing Year 10 Science support

Year 10 science practice should help students connect visual evidence to concepts: inheritance, natural selection, conservation of atoms, net force, climate systems, and inquiry data. These examples preview that visual reasoning before the no-login Year 10 Science demo.
