Lesson 1: Rock Detectives (The Three Types of Rocks)

Materials: 3 slices of different colored bread, peanut butter or jam, small chocolate chips, a heavy book, a collection of real rocks (smooth, bumpy, and sparkly), magnifying glass.

Learning Objectives

• Identify that rocks come in different shapes, sizes, and colors.
• Understand that there are three main ways rocks are made (Igneous, Sedimentary, Metamorphic).

1. Introduction (The Hook)

Talking Point: "Did you know the ground beneath your feet is like a giant history book? Every rock has a story! Today, we are going to be Rock Detectives. We’re going to find out how rocks are 'born' using a special snack!"

2. Body (I Do, We Do, You Do)

I Do (The Story of Three): Explain the types using simple analogies.

• Igneous: "Fire Rocks" made from hot lava that cools down.
• Sedimentary: "Sandwich Rocks" made from layers of sand and mud pressed together.
• Metamorphic: "Change Rocks" that get squished and heated until they look different.

We Do (The Rock Sandwich): Let’s build a Sedimentary rock!

• Take a slice of bread (mud), spread jam (sand), add chocolate chips (pebbles), and another slice of bread.
• Press down with your hand. This is pressure.
• Now, use the heavy book to squish it even more. Tell the students: "You just turned your 'Sedimentary' sandwich into a 'Metamorphic' sandwich because of the pressure!"

You Do (Sorting Mission): Give the students a pile of real rocks. Ask them to sort them into three piles based on what they see: "Layered/Crumbly," "Glassy/Holey," and "Sparkly/Hard."

3. Conclusion & Assessment

Recap: Ask, "Which rock is made from fire?" and "Which rock has layers?"
Success Criteria: The student can correctly group rocks by their physical appearance and name one way a rock is formed.

Differentiation

• ASD Support: Use a "First/Then" board (First we build the sandwich, Then we sort the rocks). Provide a sensory bin with sand and rocks for tactile exploration.
• Advanced: Ask the student to draw a picture of a volcano (Igneous) and a riverbed (Sedimentary).

Lesson 2: The Sparkle Squad (Minerals vs. Rocks)

Materials: A chocolate chip cookie, a plain cracker, a magnifying glass, a piece of white unglazed ceramic tile (or the back of a bathroom tile), several different rocks.

Learning Objectives

• Distinguish between a rock (a mix) and a mineral (one single ingredient).
• Perform a "Streak Test" to identify mineral colors.

1. Introduction (The Hook)

Talking Point: "If a rock was a cookie, the minerals would be the flour, the sugar, and the chocolate chips! Today, we are going to look for the secret ingredients inside our rocks."

2. Body (I Do, We Do, You Do)

I Do (The Cookie Comparison): Show the chocolate chip cookie. "Is this just one thing? No! It’s a mix. That’s like a rock. Now look at the sugar crystal. It’s just one thing. That’s a mineral!"

We Do (The Magnifying Search): Use magnifying glasses to look closely at rocks. Ask: "Do you see different colors? Do you see bits of sparkle? Those are the minerals (the ingredients) hiding inside!"

You Do (The Streak Test): Explain that minerals have a "secret color."

• Take a rock and rub it across the white tile like a crayon.
• Does the color of the powder (the streak) match the rock? Sometimes a gold-colored rock leaves a black streak!
• Have the students "draw" with three different rocks and record the colors they see.

3. Conclusion & Assessment

Recap: "Are minerals the ingredients or the whole cookie?"
Success Criteria: The student can explain that minerals are what make up rocks and successfully complete a streak test.

Differentiation

• ASD Support: Provide a visual checklist of the steps for the Streak Test. If the sound of the rock scratching the tile is bothersome, offer noise-canceling headphones.
• Advanced: Have the student use a "Mineral Identification" chart to guess the names of the minerals based on their streak color.

Lesson 3: The Gemstone Journey (Hardness & Value)

Materials: A piece of chalk, a penny, a steel nail, a smooth river rock, photos of a diamond and a ruby, "Gemstone" stickers or plastic beads.

Learning Objectives

• Understand that some minerals are called "Gems" because they are rare and beautiful.
• Learn about "Hardness" using the Mohs Scale (simplified).

1. Introduction (The Hook)

Talking Point: "If you found a treasure chest, what would be inside? Shiny gems! But how do we know if a gem is super strong or soft like butter? Let's test their muscles!"

2. Body (I Do, We Do, You Do)

I Do (Hard vs. Soft): Explain that scientists use a "Scratch Test" to see how hard a rock is. A Diamond is the king of hardness—nothing can scratch it but another diamond!

We Do (The Scratch Test Lab):

• Try to scratch the chalk with your fingernail. Did it leave a mark? (Yes, chalk is soft).
• Try to scratch the river rock with your fingernail. Did it work? (No).
• Try to scratch the river rock with the penny, then the nail. Which one was stronger?

You Do (Gem Sorting & Design):

• Show pictures of "Raw" gems (how they look in the dirt) vs. "Polished" gems (how they look in rings).
• Activity: Give the students "dull" rocks and have them "polish" them by washing them in soapy water and then applying a little vegetable oil with a cloth to make them shine like gems.

3. Conclusion & Assessment

Recap: "Which is harder: a diamond or a piece of chalk? How do we know?"
Success Criteria: The student can rank three objects from softest to hardest based on the scratch test.

Differentiation

• ASD Support: Use a clear "Hard" bucket and "Soft" bucket for sorting. Focus on the tactile feel of the smooth "polished" rock vs. the rough "raw" rock.
• Advanced: Introduce the numbers 1-10 (Mohs Scale) and have the student assign numbers to their tested objects.

Lesson 4: Fossil Finders & Rock Stars (Real World Uses)

Materials: Play-dough or clay, small plastic dinosaurs or shells, a pebble, a piece of graphite (pencil lead), a small mirror.

Learning Objectives

• Understand how fossils are formed in sedimentary rock.
• Identify ways we use rocks and minerals in our daily lives (pencils, buildings, jewelry).

1. Introduction (The Hook)

Talking Point: "Rocks are not just for sitting on the ground. They are Rock Stars! They are in your pockets, your pencils, and even in your walls. They also keep secrets from millions of years ago!"

2. Body (I Do, We Do, You Do)

I Do (The Fossil Secret): Explain that sometimes a plant or animal gets trapped in "Sandwich Rock" (Sedimentary) and leaves a print behind. That’s a fossil!

We Do (Making Fossils):

• Flatten a piece of play-dough.
• Press a plastic dinosaur or shell into it firmly.
• Carefully lift it up. "Look! You just made a fossil mold!"

You Do (The Rock Hunt): Go on a "Rock Use Hunt" around the house or classroom.

• Find a pencil (Graphite/Mineral).
• Find a sidewalk or brick wall (Rock/Stone).
• Find a piece of jewelry (Gemstone).
• Find a mirror or window (Glass is made from sand/minerals!).

3. Conclusion & Assessment

Recap: "Name one thing in this room that is made from a rock or mineral."
Success Criteria: The student can explain that a fossil is a print in a rock and identify at least two real-world uses for rocks.

Differentiation

• ASD Support: Provide a "Scavenger Hunt" sheet with pictures of the items they need to find (pencil, ring, window) to reduce anxiety during the hunt.
• Advanced: Create a "Rock Museum" display where the student labels their play-dough fossils and their rock collection from the past 4 weeks.
