25 Earth science project ideas for science exhibition

Exploring Earth science through hands-on projects can enhance understanding and spark curiosity about the natural world.

Here are 25 Earth science project ideas covering various topics such as geology, meteorology, oceanography, and environmental science:

Geology Projects

  1. Rock Identification and Classification
    • Collect and classify rocks based on their properties (igneous, sedimentary, metamorphic).
  2. Modeling Plate Tectonics
    • Create a model using clay or foam to demonstrate how tectonic plates move and interact.
  3. Volcano Eruption Simulation
    • Build a volcano model and simulate eruptions using baking soda and vinegar.
  4. Soil Erosion Experiment
    • Investigate the effects of water, wind, and vegetation on soil erosion using different soil samples.
  5. Crystal Growth
    • Grow crystals from a supersaturated solution and study their formation and structures.

Meteorology Projects

  1. Weather Station Creation
    • Build a simple weather station to measure temperature, humidity, wind speed, and precipitation.
  2. Cloud Formation Experiment
    • Simulate cloud formation in a jar using hot water, ice, and hairspray.
  3. Tornado in a Bottle
    • Create a tornado model using two connected bottles and study the vortex formation.
  4. Comparing Local Climates
    • Collect and compare weather data from different locations to study microclimates.
  5. Impact of Pollution on Rainfall pH
    • Measure the pH of rainwater in different areas and analyze the impact of pollution.

Oceanography Projects

  1. Ocean Currents Model
    • Use a tank of water, salt, and food coloring to demonstrate how temperature and salinity affect ocean currents.
  2. Salinity and Density Experiment
    • Study how varying salinity levels affect water density and buoyancy.
  3. Coral Reef Model
    • Build a model of a coral reef and discuss its ecological importance and threats.
  4. Oil Spill Cleanup Simulation
    • Simulate an oil spill and experiment with different methods of cleaning it up.
  5. Tsunami Generation and Impact
    • Create a model to show how tsunamis are generated and their impact on coastal areas.

Environmental Science Projects

  1. Air Quality Monitoring
    • Build an air quality monitor to measure particulate matter in different environments.
  2. Composting and Decomposition
    • Set up a composting project to study the decomposition process and its benefits for soil.
  3. Renewable Energy Sources Comparison
    • Construct small models of solar, wind, and hydroelectric power systems and compare their efficiency.
  4. Water Filtration System
    • Design and test a water filtration system using natural materials.
  5. Microplastics in Waterways
    • Collect water samples from local waterways and analyze them for the presence of microplastics.

Astronomy and Earth Interaction Projects

  1. Phases of the Moon Model
    • Create a model to demonstrate the phases of the moon and their causes.
  2. Solar and Lunar Eclipses
    • Use balls and a light source to simulate solar and lunar eclipses.
  3. Impact Craters
    • Experiment with different materials to create impact craters and study their characteristics.
  4. Modeling the Solar System
    • Build a scale model of the solar system and discuss the relative sizes and distances of planets.
  5. Seasons and Earth’s Tilt
    • Use a globe and a lamp to demonstrate how the tilt of Earth’s axis causes seasons.


These Earth science projects cover a broad spectrum of topics and offer engaging ways to explore the natural world.

Each project can be adapted for different educational levels and resources, making them suitable for a wide range of learning environments.
