The student will be able to identify the physical properties of rocks and minerals and categorize like properties by the end of the lesson. The student will be able to distinguish between rocks and minerals by the end of the lesson. Anticipatory Set: The students will take a pre-lab survey. I will ask the students to respond to my statements with a thumbs up if they agree or a thumbs down if they disagree. I will keep a tally on the board of the pre-lab survey results. These are the questions I will ask: If you pick a rock up off the ground, it is probably older than dinosaurs. (TRUE) Expected response: False Some rocks are formed in volcanoes. (TRUE) Expected response: True Some rocks float in water. (TRUE) Expected response: False When two minerals are pushed together they form a rock. (TRUE) Expected response: True Overtime, water can shape rocks. (TRUE) Expected response: False Patrick Star lives under a rock. (TRUE) Expected response: True This will get the students to start thinking about rocks as they actively participate. Input: Before the students divide into lab groups, I will demonstrate what the students should be thinking when examining rocks. I will demonstrate what each student will do with their six different rocks or minerals. I will use a piece of pumice as my example. I will show each student the rock and let each student feel the rock. I will draw on the board the square resembling the square on their paper. I will write these characteristics next to my square: color, size, texture, shape, weight, and rock or mineral. I will draw a picture and write “pumice” in my square. I will write and say aloud the physical characteristics I notice. I will say this as I write: “The color is light tan. The size is about the size of a lemon. The texture is course and looks like a dry sponge. The pumice looks like a brain in shape. It is very light weight. It is a rock not a mineral. I know this because it is not shaped like a crystal.” “Minerals are shaped like crystals. Rocks are two or more minerals pushed together. Sometimes we can look at rocks and see that they have layers. This is an easy way to tell if it is a rock or a mineral.” Before I tell the students that this is what they will be doing, I will show them a cool characteristic about pumice. I will put the pumice into a cup filled with water and I will show them that pumice floats. I will tell the students that this is what I want them to do with each rock in their lab. I will break the students into groups of four. There will be five groups. Each group will be given five rocks and one mineral. The rocks and mineral will be labeled by name. I will use these rocks: granite, gneiss, limestone, shale, and pyrite. I will use the mineral quartz. Each student will fill out their lab charts during the lab. Each student will draw each of the six rocks or mineral per group and write the name on the square on the lab paper. The student will write the characteristics they notice next to the square. The characteristics the students will look for are: color, size, texture, shape, weight. Then the student will circle on the lab sheet if it is a rock or a mineral. Modifications for students with exceptionalities: Vision impaired: The vision impaired students can still participate in this lab. Students should receive assistance from other students when forming color descriptions. Vision impaired students will receive the following rocks and minerals: Pyrite, Quartz, Limestone, and Granite. Students will use other senses to help them distinguish between the rocks such as feeling, and scent. I expect the student to define the texture of the rocks and minerals as smooth or rough. I expect the student to relate the shape of the rocks and minerals to another relatable object. The student can feel the points and edges of the rocks and minerals. The student can smell the rocks and minerals and notice some differences. The pyrite will smell of metal. The limestone will smell of dirt and dust. Some rocks and minerals will have no scent and that should be noted as well. The vision impaired students should be able to identify a texture or scent characteristic distinguishing each of their four rocks or minerals. This is how the student will be assessed. ADHD students: This lesson plan addresses some of the needs of ADHD students in its original form. The lesson has the children move around the room while working on short assignments. The objectives are simple and clear. ADHD students will receive extra time to finish assignment. The material in the lesson plan (the drawing worksheet, the summation worksheet, and the journal prompt) will be broken into mini assignments for the ADHD students instead of a packet. This will help the students feel less overwhelmed. As I walk around the room and listen to discussion, I will pay particular close attention to the groups with ADHD students. I will help their discussions but suggesting ideas to keep ideas flowing. When the students are engaged in an active discussion, the ADHD students will pay better attention. Guided Practice: The students will discuss the characteristics of the rocks and mineral in the lab groups together. They will use different terms to describe the rocks and mineral. This will help them build on the characteristics describing the rocks and mineral. I will walk around the room and listen to the descriptions. I will ask the students these questions to help get them thinking: Which rock has visible layers? How can you tell? Expected response and further discussion: Gneiss and Granite; You can see that there is more than one color so it is minerals pushed together. You can see the layers. Which one is the mineral? How do you know? Expected response and further discussion: Quartz, some may say Pyrite; Quartz is the only mineral in the room. You can tell by the crystal shape. Pyrite is not a mineral because you can see the smashed rock material around the smooth gold components. Which one(s) have you seen before? Where? Expected response and further discussion: Limestone makes up gravel roads, Granite looks like some countertops, and Shale looks like a chalkboard, Which one seems like you could break it? Why? Expected response and further discussion: The Limestone and the Shale; they are flatter and seem more fragile. Some corners break off easily. Student conversation: I expect to hear students describe the rocks. I expect to hear students talk about when and where they have seen the rocks and minerals before. I expect to hear some students talk about a movie which may have feature pyrite as fool’s gold or quartz as a magical stone. I expect the students to think about the limestone as gravel in their driveway or on a playground. I expect to hear some students think about shale as limestone. I expect some students to talk about the floating pumice and ask if other rocks float. I expect some students to talk about other rocks and minerals they have encountered but are not included in the lab. When listening for descriptions I should expect to hear the following from the students: Color: Grey, black, clear, gold, pink specks, black specks, black stripes, etc. Size: Students should compare the rock to something of a similar size such as a lemon, a strawberry, a pencil tip, etc. Texture: Rough, course, smooth, etc. Shape: Round, flat, cube, etc. Weight: Students should compare the weight to something similar in weight such as a lime, a cracker, a pencil, etc. When students are classifying the item as rock or a mineral I should expect to hear the following descriptions: Rock: Rough, multi-colored, layers, odd shape, etc. Mineral: Crystal shape, smooth, one color, etc. Independent Practice: I will give a worksheet for students to complete in class. Once students are finished, I will ask them about the answers on the worksheet. The first part of the worksheet will be matching. I will use the same rocks as in the lab but I will find pictures that have different shapes. The students will match the name of the rock to the picture. They may use their lab sheet for notes. The second part of the worksheet will be labeling pictures as “Rock” or “Mineral”. Students can look at more than one type of mineral. They will be easily identified because they will all have a crystal shape. When we go over the worksheet in class I will ask the students how they knew the answer individually as they answer my questions. Assessment: The assessment for this lab will be a journal. This will be my writing prompt: Pretend you are a geologist on a mission to build a rock and mineral collection for a new museum opening in your town. You are searching for rocks and minerals but they all have to be different. Write about some rocks and minerals that you are familiar with and their characteristics that make them different. Make sure you say which are rocks and which are minerals. This journal will identify the following objectives: Distinguish between rocks and minerals. Identify physical characteristics of rocks. Identify physical characteristics of minerals. KEY Match the name of the rock to the picture of the rock. A. B. C. D. E.
