2. Essential Concepts Soil Matrix Soil Diagram Then you may complete the anticipation guide on the essential concepts.

3. Plants need soil to grow. What else do you know about soil? Circle Map

4. Share your ideas with the class. more What are some different types of soil? Soil

25. Different soils have different colors.

26. Look at the colors of humus, sand, and clay. What kind of soil has each color? loam sand clay reveal

27. Different soils have different textures.

28. Match each type of soil to its texture. humus sand clay gritty smooth medium

29. Some soils drain more quickly or more slowly than others.

30. Which soil drains more quickly? More slowly? drains quickly drains slowly clay sand loam

31. Match the plants to the soil they grow best in. Different kinds of plants grow best in different kinds of soil.

32. sand humus

33. Let's Review!

34. Soil is... found on the ground dirty brown plants need it worms live in it has rocks and pebbles in it

35. sand loam

36. Let's Make Some QUALITATIVE Observations! ClayHumus SandSilt What does it feel like? What does it look like? What does it smell like?

37. Type of SoilLooks Like:Feels like: ______________Color: White or tan Texture: Can easily see grains Rough ______________Color: Dark brown or black Texture: Has some clumps, can see some grains Smooth ______________Color: Red Texture: Clumps together easily, cannot see individual grains Very soft and smooth Use your observations to complete this chart in your journals.

39. You're the scientist today! Get ready to get down and dirty!

40. Can Soil Hold Water?

42. Objective: Hypothesis: Materials: Data: Let's prepare for our investigation! To determine how well different soils hold water. You decide! Filters, Graduated cylinder, cups, water, sand, humus, clay, calculator Put your calculations and observations here!

43. Our Procedures 1.Put a coffee filter in an empty cup, and overlap the sides of the filter over the cup sides 2.Put 1 ounce of soil inside the coffee filter. 3.Measure 30 mL of water with the graduated cylinder. 4.Pour the water over the soil. 5.Measure the water that drains through the filter with the graduated cylinder. 6.Subtract the amount from 30 mL to find out how much water their soil held. 7.Put this amount in a chart on the board created by the teacher. 8.Copy the chart in their journal and fill in the information as groups report to the board. 9.Find the average with a calculator. (Add all the numbers in one column and divide by the number of numbers you added together.) Example: 100+90+80=270, Then 270/3=90. So my average is 90. 10.Analyze the results.

44. SandHumusClay Group One Group Two Group Three Average: Can Soil Hold Water? (Remember to subtract the amount of water that drained through the soil from 30 mL to find out how many milliliters your soil held.) Conclusion:

45. Reflection Question: Two geraniums are planted in two different types of soil (humus and clay). Tell how the geraniums will change after two weeks in each soils. Which will have a better chance of survival? Why?
