SC.4.E.6.5 Investigate how technology and tools help to extend the ability of humans to observe very small things and very large things.
SC.4.E.6.1 Identify the three categories of rocks: igneous, (formed from molten rock); sedimentary (pieces of other rocks and fossilized organisms); and metamorphic (formed from heat and pressure).
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.
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.
discuss the types of investigations in which a webcam, telescope, microscope, or hand lens might be used.
research the histories of the microscope and telescope reporting on what is learned.
identify the telescope and satellite as tools that have allowed scientists to see very large things, such as the Earth, the solar system, and parts of the universe.
se technology and tools to study and investigate samples of rocks.
observe and identify examples for each of the three categories of rocks (igneous, sedimentary, and metamorphic).
construct models for each of the three categories of rocks to include major details.
explain, pictorially and in words, the different ways rocks are formed.
describe how each category of rock is formed. igneous – formed from molten rocks sedimentary – formed with other pieces of rock and fossilized organisms metamorphic – formed from heat and pressure differentiate between the three different categories of rocks based on how each is formed and/or their physical property
use manipulatives or drawings of rectangular arrays and/or array models to solve and explain multi-digit multiplication
apply an understanding of rectangular arrays and area models to connect to the partial products strategy.
