Earthquakes: When the Ground Shakes

Active learning turns abstract seismic forces into visible, memorable moments. When Year 4 students feel real shaking or map real data, abstract concepts like energy release and tectonic boundaries become concrete and personal. These hands-on activities build accurate mental models that correct common media myths about cracks and damage.

Activity 01

• Simulation Game
• 45 min · Small Groups

Simulation Game: Shake Table Challenge

Students build simple structures from straws, marshmallows, and blocks on layered jelly or sand trays. Shake the table at varying speeds to mimic magnitudes. Groups record damage levels and redesign for stability, discussing improvements.

Explain the causes of earthquakes and how they are measured.

Facilitation Tip

During the Shake Table Challenge, circulate and ask each group to predict where their structure will fail before turning on the table, then compare predictions to outcomes.

What to look for

Students complete a card with two prompts: 1. 'Name one cause of earthquakes and explain it in one sentence.' 2. 'List two safety actions to take if you feel shaking during an earthquake.'

Activity 02

• Role Play
• 30 min · Pairs

Pairs: Magnitude Effects Sort

Provide cards showing earthquake magnitudes, descriptions of shaking, and photos of structural damage. Pairs match and sequence them from mild to severe. Follow with a class chart to compare predictions against real examples.

Compare the effects of different magnitude earthquakes on structures.

Facilitation Tip

For the Magnitude Effects Sort, remind pairs to justify their placements by referencing both the Richter scale descriptors and the images of damage.

What to look for

Present students with images of two different buildings, one lightly damaged and one severely damaged after an earthquake. Ask: 'What might have caused the difference in damage? How does earthquake magnitude play a role?'

Whole Class: School Safety Plan

Brainstorm hazards and responses in a class discussion. Vote on key steps like identifying safe spots. Practice a full drill, then refine the plan into posters for the classroom.

Design an emergency plan for earthquake safety in a school setting.

Facilitation Tip

When running the School Safety Plan, assign roles such as recorder, presenter, and safety officer so every student contributes meaningfully to the final plan.

What to look for

Ask students to hold up fingers corresponding to the magnitude of an earthquake: 1 finger for minor shaking, 3 fingers for moderate shaking, 5 fingers for severe shaking. Then, ask them to demonstrate the 'drop, cover, and hold on' action.

Activity 04

• Role Play
• 35 min · Individual

Individual: Seismograph Model

Each student assembles a basic seismograph with a cup, string, marker, and paper drum. Shake the desk gently; draw wave patterns. Share sketches to identify similarities with professional seismograms.

Explain the causes of earthquakes and how they are measured.

Facilitation Tip

While students build seismograph models, emphasize precision in the pen-to-drum alignment so small shakes produce visible traces.

A few notes on teaching this unit

Start with the seismograph model to introduce waves as traces, not just invisible forces. Then move to the shake table to show how shaking, not cracks, causes collapse. Conclude with mapping to anchor causes in real geography. Avoid overemphasizing Richter numbers without tying them to observable effects, and steer clear of dramatic footage that reinforces misconceptions about gaping chasms swallowing cities.

Students will explain causes of earthquakes, measure shaking on scales, compare damage outcomes, and apply safety actions confidently. They will use evidence from simulations, maps, and models to justify their thinking in discussions and exit tasks.

Watch Out for These Misconceptions

• During the Shake Table Challenge, watch for students attributing collapses to cracks in the table or gaps opening beneath buildings.

  Ask teams to observe how columns buckle or topple without any visible surface tears, then prompt them to describe the motion that caused failure instead of focusing on cracks.

• During the Magnitude Effects Sort, watch for students assuming higher magnitudes always create proportionally larger surface cracks.

  Have students compare the Richter scale descriptors on their cards with images of damage; guide them to notice that a magnitude 7 releases ten times more energy than a 6, leading to far greater structural damage rather than longer cracks.

• During the mapping portion of the School Safety Plan activity, watch for students placing earthquake dots randomly across continents.

  Provide world maps with plate boundary outlines and ask students to trace the boundary edges before plotting quake data, making the clustering at plate edges visible and unavoidable.
