Katy Rock Shop now offers an Earth Science🌍 Class Series! There are 3 classes that occur on the first 3 Thursdays of the month. Each Thursday features 1 class, repeated 3 times a day.

Class 1: 11-12pm

Class 2: 3-4pm

Class 3: 4:30-5:30pm

PLEASE pay for your kiddos/group here prior to the event. In the notes, at the time of payment please include your kiddos names, their ages, and the date of the class and your prefered class time. Seats are limited, so book early!

We encourage you to share the class with your friends or in your Facebook groups for your party to get discounted classes.

• 1 child = $20
• 2-5 kids = 5% off
• 6-10 kids = 10% off
• 11-15 kids = 15% off
• 16-25 kids = 20% off

We currently offer 3 Earth Science 🌍 classes for fall semester 2025 and have 25 seats available per class.

1. The Rock Cycle on 1st Thursday

The miners will learn how to use a magnifying glass, 🔍 observe a rock’s grains, feel texture differences and relate all their observations to the three major rock groups. Critical skills subjects include: gravity, buoyancy, observation, deduction reasoning, & identification of igneous, metamorphic & sedimentary rocks.

2. Hardness Testing with the Moh’s Scale on 2nd Thursday

Learn about the Moh’s Hardness test and Streak testing and how to apply the critical skills and to identify the tricky ones using these techniques to test rocks safely at home or in the field! Critical skills include rock vs. mineral, atoms, bonds, density, hardness, streak, observation and deductive reasoning.

Kiddos review the rock cycle, gravity, buoyancy, atoms, bonds, density, and how these influence hardness.

3 Fossils and Lithification on 3rd Thursday!

During the Fossils & Lithification class, the kiddos will learn about fossil types (molds, casts), about how layers deposit in rivers and oceans, and how fossils get preserved through the process of lithification and cementation.

The class will involve running 3 experiments and of course each person gets to mine for fossils with the Sluice!

The first experiment will be creating fossil molds, the second will be how sedimentary layers become stratified from particle settling velocity, and the third will be mineral crystallization, sped up for kids to observe the process!

We encourage you to start with the Rock Cycle, as those skills are used in subsequent classes.
