1.E.2.2 Compare the properties of soil samples from different places relating their capacity to retain water, nourish and support the growth of certain plants.

STRAND: EARTH SYSTEMS, STRUCTURES AND PROCESSES GRADE: 1st

Essential Standard: 1.E.2 Understand the physical properties of Earth materials that make them useful in different ways.

Clarifying Objective: 1.E.2.1 Summarize the physical properties of earth materials, including rocks, minerals, soils and water that make them useful in different ways. 1.E.2.2 Compare the properties of soil samples from different places relating their capacity to retain water, nourish and support the growth of certain plants.

1.E.2.1 What are physical properties? Begin lesson by describing one object in the classroom. Write down everything the students observe about the item; Shape, size, color, weight, texture. After you discuss the item and talk about the 5 properties place students in pairs or groups. Give them a cup of mixed shells and rocks. Have the students classify/sort them based on their physical properties. Discuss with the students how they decided to sort their objects.

1.E.2.1 What are the different properties of rocks, minerals, soil, and water? Give each student one 5x8 index card and have them fold it into 3 equal rectangles (teacher may want to prepare the cards a head of time). Draw a line down to divide the 3 columns. In rectangle 1 make a circle with the glue and use the spoon to sprinkle the clay soil on it. Then press it down so it sticks to the card. Repeat with humus and sand in the other two columns. Then have the students use their magnifying glasses to observe one soil sample at a time. As a whole class record the different properties of each soil and list it in the same column as the soil sample. Finish describing properties for all three soil samples. Ask: How big are the particles of sand? Of clay? What shape are the particles found in humus? Are they all the same? Do all the sand particles look the same?

1.E.2.1 How can you classify rocks? Take the students outside to find a special rock (this could also be assigned for homework prior to lesson). Have the students use a magnifying glass to observe their rocks physical properties. Then have the students report to their groups the properties of their rocks. Once all the students have reported ask the students to classify their rocks as a whole group. Use a piece of white paper with two circles draw on them for the students to place their rocks inside of when classifying them. Example in 1st Grade McMillan McGraw Hill Textbook page D5

1.E.2.2 What is clay, humus and sand soils capacity to retain water? Students will observe as a whole class how much water each type of soil holds. Place 1 piece of 3”x3” screen over the bottom of the funnel. Place the screen and funnel on top of 1 graduated cylinder. Then pour ½ cup of clay soil into the funnel. (a few pieces of soil may fall through and that is ok). Then fill a 2nd funnel with 50ml of water. Pour the 50 ml of water into the clay soil and observe how much water comes out. Repeat procedures with the remaining soils, cylinders, funnels and screens. Then place all 3 soil cylinders next to each other and observe which soil holds the most water and the least amount of water. How can this help or hurt plants ability to survive?
