1 GRADE 1 WHAT DOES IT MATTER? Unit Summary: Students will observe and explore changes in physical properties by large and small, slow and fast processes. Also classify matter by properties. Length of Unit: Critical Questions: What are the properties of different objects? How can you change water? How can we change the properties of different materials? What is the most important liquid? Ohio Standards Connections: Standard(s): Physical Science, Scientific Ways of Knowing, Scientific Inquiry Benchmark(s): K2PSA A. Discover that many objects are made of parts that have different characteristics. Describe these characteristics and recognize ways an object may change. K2SIB B. Design and conduct a simple investigation to explore a question. K2SIC C. Gather and communicate information from careful observations and simple investigation through a variety of methods. K2SKA A. Recognize that there are different ways to carry out scientific investigations. Realize that investigations can be repeated under the same conditions with similar results and may have different explanations. Indicator(s): 1SK1 1. Discover that when a science investigation is done the same way multiple times, one can expect to get very similar results each time it is performed. 1SK2 2. Demonstrate good explanations based on evidence from investigations and observations. 1SK3 3. Explain that everybody can do science, invent things and have scientific ideas no matter where they live. 1SI1 1. Ask "what happens when" questions. 1SI2 2. Explore and pursue student generated "what happens when" questions. 1SI3 3. Use appropriate safety procedures when completing scientific investigations. What Does It Matter?

2 1SI4 4. Work in a small group to complete an investigation and then share findings with others. 1SI5 5. Create individual conclusions about group findings. 1SI6 6. Use appropriate tools and simple equipment/instruments to safely gather scientific data (e.g., magnifiers, timers and simple balances and other appropriate tools). 1SI7 7. Make estimates to compare familiar lengths, weights and time intervals. 1SI8 8. Use oral, written and pictorial representation to communicate work. 1SI9 9. Describe things as accurately as possible and compare with the observations of others. 1PS1 1. Classify objects according to the materials they are made of and their physical properties. 1PS2 2. Investigate that water can change from liquid to solid or solid to liquid. 1PS3 3. Explore and observe that things can be done to materials to change their properties (e.g., heating, freezing, mixing, cutting, wetting, dissolving, bending and exposing to light). 1PS4 4. Explore changes that greatly change the properties of an object (e.g., burning paper) and changes that leave the properties largely unchanged (e.g., tearing paper). PreAssessment: Create and chart student lead list of Anything. Ask students to try to sort items into 3 groups. You then sort them into the groups of solid and liquid (poss. gas). Have them guess why you put things where you did. Scoring Guidelines: Ongoing Assessment: Journaling PostAssessment/Summative Assessment: Draw 4 uses of water. Scoring Guidelines: Instructional Procedures: Provide a variety of materials for students to sort. They report/share why they chose those groups. Make Slime/Oobleck 1 teaspoon white school glue, 1 teaspoon liquid starch, food coloring, waxed paper, timer mix ingredients on waxed paper with a spoon. Stir until a substance forms. Let it stand for 34 minutes. Roll and knead for 1 minute. See Indicator 1PS3 for ideas Read Alouds Can you change water? Put ice cube on a plate. It is a solid. Can you change it? Try List properties of Matter bendable, not bendable, float, sink, hard, soft, round, square, smooth, rough, small, thick, sticky, living, nonliving, round, tall Children create lists of Solids, Liquids (poss. Gas) found in classroom or school. What Does It Matter? Trumbull County Educational Service Center Page 2

3 Venn DiagramSolids Liquids (they both have a certain size) Make ice cream and ice cubes Dissove salt/sugar into water. Wet a sponge and dry it out. Too much sunlight = sun burn Solar dough see Brice Harris for further info. Call him, he ll help! Ice Balls Experiment put equal amounts of water into the balloons so they are each about 3 inches in diameter. Let out any air before you tie them off and put them into the freezer. The next day cut away the balloon, with scissors, and examine the ice inside. Do you think the ice balls will float or sink in water? Fill the bowl with water to see. Sprinkle salt on an ice ball, and discover what happens. Sprinkle sugar on another, and compare the results. Go into a dark room or closet, and shine a light through one of the ice balls. Observe what happens. *What s happeningwhen water freezes, it expands nad air pockets form, making it less dense that the liquid water. That s why it floats instead of sinking to the bottom. Salt causes ice to melt, but sugar doesn t. That s why we sprinkle salt on icy sidewalks in the winter. The ice reflects light in every direction, so the whole ball glows when you shine the flashlight directly on it. Name that Liquid guessing game What liquid.. makes our cars go, smells very nice, white that comes from cows, thick and sticky and goes on pancakes? Burn a candle hard and soft wax = solid to liquid Melting chocolate chips/melting chips and then pour it over small cups of icecream and it freezes into a solid again. Melt crayons. Make ice cream or popcorn. Whisk egg whites into foam/fluff. Make caramel apples by melting caramel or stretching the caramel blocks. Find Solids with these Properties= solid that breaks when dropped, solid that bounces, that is thick, that is thin, that you cannot bend, that heavy, that is green Change paper by ripping, burning, wetting, cutting and discussing.

4 Burn wood, light craftstick/balsa wood/wooden match Cooking scrambled eggs. Washing dishes vs. dissolving koolaid Read Snowballs ask and list other things that can melt. Collect snow in winter and let it melt. Try to change an ice cube.

5 Homework Options and Home Connections: List ways to save water at home. How can you get the salt out of pepper? Mix ½ cup salt and 1 teaspoon pepper The challenge is to separate the two. Test your ideas. There is no right answer. Picking pepper out is slow and tedious. Dissolving the salt in water and straining the solution through a cloth is more efficient.

6 Matter can be touched or held. Have ice on hand. Various tools/objects on hand if you do Can you change water? Literature Connections: Snowballs Lois Ehler The Snowy Day Jack E.

Branley Solids, Liquids and GasesStates of Matter and How They Change Scholastic What Floats? What Sinks? Margie Burton, Cathy French, Tammy Jones Topic Relationship to other grades; Pulls from, Pushes to:. KPS3 3. Describe and sort objects by one or more properties (e.g., size, color and shape). 4PS1 1. Identify characteristics of a simple physical change (e.g., heating or cooling can change water from one state to another and the change is reversible). 4PS2 2. Identify characteristics of a simple chemical change. When a new material is made by combining two or more materials, it has chemical properties that are different from the original materials (e.g., burning paper, vinegar and baking soda). 4PS3 3. Describe objects by the properties of the materials from which they are made and that these properties can be used to separate or sort a group of objects (e.g., paper, glass, plastic and metal). 4PS4 4. Explain that matter has different states (e.g., solid, liquid and gas) and that each state has distinct physical properties.
