6 Interactive Earth Science Activities that Rock

1. crafting your seismograph at home.

Students build a simple seismograph to understand how earthquakes are recorded.

• Sturdy Shoe Box or Small Cardboard Box: This will act as the housing for the seismograph.
• Weight (e.g., a small, heavy object such as a washer or a dense rock): It serves as the mass that remains stationary during vibrations.
• String: To suspend the weight inside the box.
• Paper Roll: This will be used to record the seismic waves. A long strip of paper or a continuous paper roll that fits inside the box is ideal.
• Markers or Pens: Attached to the weight of the box, to draw the seismic waves on the paper.
• Scissors: For cutting the string and modifying the box if necessary.
• Tape and/or Glue: To secure components inside the box and attach the marker or pen to the weight.

Preparation:

• Modify the Box: Cut a small hole at one end of the shoebox – this is where the paper will feed through. If possible, create another hole on the opposite side to allow the paper to roll out smoothly.
• Suspend the Weight: Tie the string around the weight. Secure the other end of the string to the top center of the box, ensuring the weight hangs freely and can move side to side or back and forth without touching the sides of the box.
• Attach the Marker: Tape or glue the marker to the weight, positioning it so that its tip lightly touches the paper roll placed at the bottom of the box.

Sealing and Placement:

• Set Up the Paper Roll: Place the paper roll inside the box so it unwinds beneath the marker tip. The paper should smoothly feed from one hole to the other (if using two holes).
• Secure the Box: Place the box in a location where it won’t be disturbed but can still record any vibrations. This could be on a solid surface or floor.

Observation:

• Monitor Activity: Over the following days, students should check the paper for any lines or marks.
• Simulate Seismic Activity: For immediate results, gently shaking the table or floor near the seismograph can simulate seismic waves, allowing the device to record “earthquakes.”

Explanation:

This ‘DIY Seismograph’ enables students to understand how seismic waves are detected and recorded. The suspended weight remains stationary due to inertia when the box (and the Earth) moves during a seismic event. This movement is then transferred onto the paper as a trace, illustrating the vibrations caused by the seismic waves.

• Ask students to experiment with different weights and markers to see how these changes affect the sensitivity and recordings of their seismographs.
• Discuss the significance of seismographs using easy to use earthquake activity and notes and by predicting potential seismic events.

By constructing and observing their seismograph, students gain a practical understanding of how seismic activity is measured. It also helps them understand the importance of earthquake preparedness and awareness in their lives.

2. Wind Erosion Experiment Time!

• A barrier (like cardboard or plastic): To partially block the wind and create different zones of wind erosion.
• A spray bottle with water: To lightly moisten the sand, mimicking natural moisture in the soil.
• Permanent markers: To label areas of the tray and to mark the initial positions of pebbles or rocks.
• Fill the shallow tray with sand to a depth of about 2-3 inches. This represents the Earth’s surface that will be subjected to wind erosion.
• Place small pebbles or rocks at various locations on the sand surface to simulate larger landscape features.
• Use the permanent markers to label different areas of the tray, such as “High Wind Zone,” “Protected Zone,” etc., based on where you plan to position the barrier and fan.
• Lightly moisten the surface of the sand with the spray bottle. This simulates natural conditions where soil might have some moisture.

Creating Wind Erosion:

• Set up the fan on one side of the tray and the barrier on the other side, leaving enough space for the wind to pass through and over the tray.
• Turn on the fan at a low or medium setting to start the wind erosion process. Adjust the fan’s speed to see how different wind intensities affect erosion.
• Students should observe the movement of sand and pebbles over time. They will notice how the sand shifts from areas of high wind exposure to more protected areas.
• They can note the difference in erosion patterns on either side of the barrier and around the pebbles or rocks.
• Encourage students to record their observations, noting the time taken for noticeable changes in the landscape.

This experiment will demonstrate how wind erosion works, showing the transport of particles from one place to another by the force of wind. 

The areas behind barriers and around larger rocks will show less erosion due to wind protection, illustrating the concept of sheltering and the varying impacts of wind erosion on different landscapes.

• Encourage students to experiment with different landscape setups, such as changing the arrangement of rocks or the moisture level of the sand, to see how these factors influence wind erosion.
• Discuss how vegetation, natural formations, and human-made structures can impact erosion and landscape change.
• Use erosion and weathering boom cards to cover types, factors, and effects.

Through this hands-on experiment, students will gain a better understanding of wind erosion, a significant geological process. This knowledge is crucial for understanding the Earth’s changing surface and the importance of managing land to prevent excessive erosion, especially in areas prone to high winds.

• Oranges: Preferably large ones to easily represent Earth’s surface.
• Knife: To cut the orange peel into sections.
• Marker: To draw and label the tectonic plates on the orange peel.
• Carefully peel the orange in a way that the peel remains in one piece or in large sections that can be reassembled to form the whole orange shape again. This intact peel will represent the Earth’s surface.
• On the inside of the peel (the white part), use the marker to draw boundaries to represent the Earth’s tectonic plates. You can base this on real tectonic plate boundaries or create hypothetical ones for the demonstration.
• Label key plates with names to provide a more educational experience, if desired.

Reassembly:

• Reassemble the orange peel sections back into the shape of an orange. This step is crucial as it simulates the Earth’s complete surface before the tectonic plates begin to move.

Demonstration of Plate Movements:

• Divergent boundaries: Move two sections apart to show how tectonic plates diverge from each other.
• Transform boundaries: Slide two sections past one another to simulate the sliding motion at transform boundaries.
• Convergent boundaries: Push two sections towards each other, one going over or under the other, to represent plate collision and subduction.
• This tactile demonstration allows students to visually and physically grasp how tectonic plates move and interact on the Earth’s surface.

This experiment models the Earth’s lithosphere’s dynamic nature and demonstrates how plate movements shape our planet’s surface, leading to earthquakes, volcanic eruptions, and mountain formation.

• Place the white paper on a table near a sunny window. If sunlight is not available, set up a bright flashlight or an overhead projector as your light source, pointing towards the paper.
• Hold the glass prism in the path of sunlight so that the sunlight passes through one of the prism’s faces.
• Adjust the angle of the prism until light refracts (bends) through the prism and a spectrum of colors is displayed on the white paper. This spectrum is your created rainbow.
• If using an artificial light source, turn off other lights in the room for a clearer observation.
• Point the light source towards the prism. Adjust the prism in the light path until you project a spectrum onto the paper or wall.
• Observe how the white light splits into a range of colors. This dispersion occurs because different colors of light bend by different amounts when passing through the prism.
• Experiment with moving the prism closer or further from the paper to see how it affects the size and intensity of the rainbow.
• Try using water by filling a clear glass with water and repeating the experiment. Note how the water acts like a prism and compare the effect.

This experiment illustrates the principles of refraction and dispersion. Light is made up of a spectrum of colors, each with a different wavelength. When light passes through a prism (or another medium like water), these wavelengths bend at slightly different angles due to their varying speeds in the medium, spreading out to form a rainbow.

• Experiment with prisms of different shapes or materials to observe variations in the dispersion pattern.
• Use this experiment to discuss the natural formation of rainbows and how they occur when sunlight is refracted and dispersed by water droplets in the atmosphere.
