Transcript of FIRST GRADE LESSON PLAN : PHYSICAL PROPERTIES OF EARTH MATERIALS

PHYSICAL PROPERTIES OF EARTH'S MATERIALS
"LAYERS OF SOIL" WHAT WE WILL BE MAKING
WHAT ARE SOME OF EARTHS MATERIALS?
* Earth materials are solid rocks and soils, water, and minerals. The materials have different properties which make them useful for different purposes,such as buildings, fuels,and food
SOILS: Part of Earth's Materials
Soils have properties of color and texture, capacity to hold water and grow plants. The three major types of soil are clay,sand, and silt/loam.
PHYSICAL PROPERTIES OF WATER
At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water so its referred to as the universal solvent. Because of this, water in nature and in use is rarely pure.
PHYSICAL PROPERTIES OF ROCKS/MINERALS
Minerals and rocks are identified by examining their physical properties. Such as, cleavage and fracture, hardness, lust and streak.
DEFINITIONS//VOCAB
Streak:the color of a mineral when it is crushed to a powder.
Luster: a description of the way a mineral surface looks when light reflects off of the surface.Cleavage and fracture:descriptions of how a mineral breaks into pieces.
O Horizon= humus
A horizon= topsoil
B Horizon= subsoil
C Horizon= weathered bedrock
There is a bottom layer called the R Horizon and that is unweathered bedrock
Who's Ready For a Lab?!
Let's make layers of the soil with edible items! Follow the teacher's directions please!
Let's Discuss the Lab!
Hint: Humus, A horizon, B horizon, C horizon, R horizon
What does each layer of candy/food represent?
