Standard(s) Taught

SC.4.P.10.1
Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.
SC.4.P.10.2
Investigate and describe that energy has the ability to cause motion or create change.
SC.4.P.10.3
Investigate and explain that sound is produced by vibrating objects and that pitch depends on how fast or slow the object vibrates.

MAFS.4.NF.1.1
Explain why a fraction is equivalent to a fraction by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size.

MAFS.4.NF2.3
Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
b. Decompose a fraction into a sum of fractions with the same denominator in more than one way,
recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.

Learning Targets and Learning Criteria

Students will:
•explain that the speed of an object is determined by the distance it travels within a unit of time.
•investigate and compare the speeds of different objects by measuring the distance each object travels during a set amount of time using tools and technology.
•investigate and compare the speeds of different objects by measuring the amount of time it takes each object to travel a set amount of distance using tools and technology.
•display obtained speeds in chart, table, and graph format.

demonstrate with concrete and visual models that adding fractions referring to the same size whole is joining parts of the wholes.
• demonstrate with concrete and visual models that subtracting fractions referring to the same size whole is separating parts of the wholes
