LEARNING EXPERIENCE Rocks Matter - Picture/People graphs ENGAGE Review the expectations of working in the outdoor classroom. Ask students to name some areas where they would be able to find rocks. What kinds of rocks might they find? (Big, little, bumpy, smooth, round, pointy, etc.) Grade Kindergarten Timeframe 45 minutes EXPLORE Materials Take students outside to look for different kinds of rocks (activity Student journals/pencils will work best if they are taken to an area with a variety of Chart paper or white stones). board/markers Ask students to choose 3 rocks that are different from one Clear packaging tape another. To avoid having students choose any that are too large, Digital camera (optional) the stones should be ones that fit into their hand and that they can hold with just two fingers. After students have each chosen three rocks, bring them back to a central location where they can share with a partner some of the different ways that they might describe their rocks (this one is smooth, but this one is rough, this one is big and this one is little, etc.) Invite students to share with the whole group some of the ways that they can describe their rocks. EXPLAIN Divide students into groups of 2 - 3. Tell them that there are many different ways that rocks can be sorted. Tell students to put all of their rocks in the middle and then have each group sort their rocks by size, making groups of big, medium and small (or just big and little). Ask students if they can think of another way to sort their rocks (by color or how they feel (texture)). Have small groups sort their rocks by color or texture. After students have done the sorting in their small groups, choose a characteristic that is relatively simple for them to distinguish (such as big, medium, and small). On a large piece of chart paper or on a white board, draw the X and Y axis of a graph. Label the X axis with the names of the different chosen categories (such as big, medium, and small) and the Y axis with “Number of Rocks”. Proceeding with one category at a time, invite students to bring those rocks to the chart paper. Using clear packaging tape, attach rocks to the chart paper above the appropriate category, creating a picture graph. ELABORATE Using the picture graph created with the rocks collected by the class, engage students in some math problems: are there more big rocks than little rocks? Which category has fewer rocks than the big rocks? How many rocks are in each category? Etc. Create a “people graph”. Go to an open area where students will have room to spread out across the ground. Ask students who have a brown rock (or some other property you identify) to line up in one line. Ask students who have a white rock to line up in another line next to the brown rock line. Ask Copyright 2014 REAL School Gardens students who have a different color of rock to form another line. Once all students are lined up in three parallel lines, ask the students to lay down “head to toe” on the ground in order to create a “people graph”. If possible, take a picture of the graph from an elevated location such as a tree cookie or boulder, piece of playground equipment, etc. Print the picture and post in the classroom and/or in each student’s science journal. EVALUATE Print the “people graph” for each student or post a copy in your classroom. Question students regarding which category has fewer, more, how many in each category, etc. OBJECTIVES Science K.5 A observe and record properties of objects, including relative size and mass, such as bigger or smaller and heavier or lighter, shape, color, and texture K.7 A observe, describe, compare, and sort rocks by size, shape, color, and texture Math K.1 A use one-to-one correspondence and language such as more than, same number as, or two less than to describe relative sizes of sets of concrete objects K.1 B use sets of concrete objects to represent quantities given in verbal or written form (through 20) K.1 C use numbers to describe how many objects are in a set (through 20) using verbal and symbolic descriptions
