Delve into the fascinating world of geology with the Starburst Rock Cycle Lab PDF, an engaging educational resource that brings the rock cycle to life. Through a series of hands-on activities, students will explore the dynamic processes that shape our planet’s crust, gaining a deeper understanding of the Earth’s geological history.
This comprehensive lab guide provides a detailed overview of the rock cycle, from the formation of igneous rocks to the weathering and erosion that create sedimentary rocks. Students will learn about the different types of rocks, their properties, and the forces that transform them over time.
Introduction
The Starburst Rock Cycle Lab is an experiment that demonstrates the rock cycle, the process by which rocks are formed, weathered, and transformed over time. The purpose of this lab is to help students understand the different types of rocks and how they are formed.
Materials Needed
The following materials are needed for the lab:
- Various types of rocks (e.g., igneous, sedimentary, metamorphic)
- Hammer
- Chisel
- Safety goggles
- Gloves
Procedures
This lab involves several steps to examine the rock cycle. Follow these steps carefully, ensuring safety precautions are adhered to.

Before beginning, ensure you have all necessary materials, including rock samples, magnifying glass, safety goggles, and gloves.
Safety Precautions
- Wear safety goggles and gloves throughout the lab.
- Handle rock samples with care, as they may have sharp edges.
- Do not ingest or inhale any rock particles.
- Dispose of waste materials properly.
Examining Rock Samples
Begin by examining the rock samples using a magnifying glass. Note their color, texture, and any visible crystals.
- Classify the rocks into igneous, sedimentary, or metamorphic based on their characteristics.
- Identify any minerals present in the rocks.
Modeling the Rock Cycle
Using the rock samples, create a model of the rock cycle. This can be done by drawing a diagram or using physical materials.
- Show the different processes involved in the rock cycle, such as weathering, erosion, deposition, and metamorphism.
- Explain how rocks can change from one type to another through these processes.
Data Collection
During the lab, data collection involves systematically recording observations and measurements to document the changes and interactions within the rock cycle.

The data collected should include:
- Observations:Qualitative descriptions of the physical characteristics of rocks, such as color, texture, and mineral composition.
- Measurements:Quantitative data, such as the size, weight, and density of rocks.
To record the data effectively, consider using:
- Field notebooks:Physical notebooks for recording observations and sketches.
- Data tables:Organized tables for recording measurements and observations.
- Photographs:Digital or physical images to document the appearance of rocks.
Data Analysis
The data collected during the lab can be analyzed using a variety of methods. One common method is to create a graph of the data. This can help to visualize the relationship between the different variables. Another method is to calculate the mean, median, and mode of the data.
This can help to summarize the data and identify any trends.
Interpreting the Results
Once the data has been analyzed, it is important to interpret the results. This can be done by comparing the results to the hypothesis. If the results support the hypothesis, then the hypothesis can be considered to be valid. If the results do not support the hypothesis, then the hypothesis can be considered to be invalid.It is also important to consider the limitations of the study when interpreting the results.
These limitations may include the sample size, the type of data collected, and the methods used to analyze the data.

Materials
- Starburst candies (original flavor)
- Toothpicks
- Water
- Ice
- Heat source (e.g., microwave, hot plate)
- Thermometer (optional)
Procedure
- Label four Starbursts with the following names: Sedimentary, Metamorphic, Igneous, and Melted.
- Place the Sedimentary Starburst in a cup of water.
- Place the Metamorphic Starburst in a cup of ice.
- Place the Igneous Starburst in a microwave or on a hot plate until it melts.
- Use a toothpick to break apart the Melted Starburst and spread it out on a flat surface.
- Allow the Melted Starburst to cool and harden.
- Observe the changes that occur to each Starburst and record your observations in the table below.
