SC.4.E.6.2 Identify the physical properties of common earth‐forming minerals, including hardness, color, luster, cleavage, and streak color, and recognize the role of minerals in the formation of rocks
SC.4.E.6.4 Describe the basic differences between physical weathering (breaking down of rock by wind, water, ice, temperature change, and plants) and erosion (movement of rock by gravity, wind, water, and ice)
SC.4.E.6.3 Recognize that humans need resources found on Earth and that these are either renewable or nonrenewable.
SC.4.E.6.6 Identify resources available in Florida (water, phosphate, oil, limestone, silicon, wind, and solar energy)
MAFS.4.NBT.2.5 Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
identify the physical properties of common earth-forming minerals, including hardness, color, luster, cleavage, and streak color
investigate and record the physical properties of minerals using technology and tools when appropriate (for hardness you may use a glass plate or other minerals; for streak color you may use a streak plate or unglazed tile).
explain that investigations of minerals do not always follow the scientific method but do involve the use of observations and evidence.
compare observations made by other classmates explaining any differences in data.
compare minerals based on physical properties.
explain the role of minerals (clay, quartz, feldspar, calcite, talc, pyrite, graphite, and mica) and their importance in rock formation (i.e.: 2 or more minerals make up a rock).
observe and record evidence of physical weathering in nature (e.g., plant roots growing up through a sidewalk, cement cracking from temperature changes).
describe causes of physical weathering occurs (wind, water, ice, temperature change, and plants).
investigate the processes of physical weathering (breaking down a rock) using a model.
observe and record evidence of erosion in a science notebook.
describe causes of erosion (gravity, wind, water, and ice).
investigate the processes of erosion (movement of rock) using a model.
discuss the cause/effect relationships for erosion and weathering.
provide examples of how physical weathering and the erosion processes change Earth’s surface (constructive and destructive)
use manipulatives or drawings of rectangular arrays and/or array models to solve and explain multi-digit multiplication problems
apply an understanding of rectangular arrays and area models to connect to the partial products strategy.
