Ohm's Law V = I × R

1. Change the voltage (V) and resistance (R) sliders.
2. Watch the current on the ammeter (I = V ÷ R).
3. Notice how bright the bulb glows.

Observation: more voltage gives more current; more resistance gives less current.

Quick assessment: If V = 6 V and R = 3 Ω, what is the current?

• 0.5 A
• 2 A
• 9 A
• 18 A

Check answer

Acids and Bases – pH test

1. Choose a solution.
2. See the universal indicator colour and pH value.
3. Watch the colour of blue and red litmus paper.

Observation: litmus does not change colour in a neutral solution.

Quick assessment: Which of these is basic (alkaline)?

• Vinegar
• Lemon juice
• Soap solution
• Tomato juice

Check answer

Plant cell and animal cell

1. Click an organelle name – it lights up in the diagram.
2. Read what it does.
3. Switch between plant and animal cell to compare.

Quick assessment: Which organelle makes food by photosynthesis?

• Mitochondria
• Nucleus
• Chloroplast
• Vacuole

Check answer

Graph plotting y = ax² + bx + c

1. Change the values of a, b and c.
2. a = 0 gives a straight line; otherwise a parabola.
3. Observe the intercept and roots.

Observation: changing c moves the whole graph up or down.

Quick assessment: Where does the line y = 2x + 1 cross the y-axis?

• (0, 1)
• (1, 0)
• (0, 2)
• (2, 1)
