COOP & Field Trip Options 🌍

Our current class list can be booked by individuals, groups or Homeschool coops. Our classes include:

1. Rock cutting & Polishing "Lapidary" (1st Thursday, September 3rd)

• Our most popular class shows Young Explorers how to tumble, polish rocks and includes rock cutting demonstrations. everyone choses rock to work and keep, however bring your own treasures if you always wanted to prepare them.
• For Junior Scientists, they learn how to tumble, polish and cut rocks!
• Rockhounds get the full experience, and their class is an evening class and lasts about 2 hours. They will learn how to use a slab saw, trim saw, reciprocating flat lap, and how to tumble.

2. Dinosaurs & Fossils (1st Thursday, October 1st)

Students will:

• Explore fossil types (molds, casts, body fossils and carbon fossils).
• Learn how layers deposit in rivers/oceans and how fossils are preserved through lithification and cementation.
• Run three experiments:
  1. Create fossil molds.
  2. Observe sedimentary layer stratification through particle settling velocity.
  3. Watch mineral crystallization sped up for easy observation.
• Mine for fossils using the sluice! everyone keeps what they find and each age group gets more advanced instruction with rock hounds getting college level insight!

3. Identifying Rocks (1st Thursday, November 5th)

Students will:

• Use magnifying glasses to observe rock grains and textures.
• Relate observations to the three major rock groups.
• Practice critical skills: gravity, buoyancy, observation, deductive reasoning, and identification of igneous, metamorphic, and sedimentary rocks, a rock vs. mineral, atoms, bonds, density, hardness, and streak testing.
• Again, instruction gets more advanced for older age groups and includes fluorescence and mohs hardness testing (college level skills for geologists!)

3. Compasses and Map Making (1st Thursday, December 3rd)

During this class, everyone will learn how to use a compass and link direction to a map. Each person will also learn to measure distance while walking. We will demonstrate a baseline and show everyone how walking a grid works. These skills will be critical for the meteorite hunt field trip.
