Curriculum objectives covered
“Sort surfaces by how much friction they cause.”
“Explain how the surface under a moving object changes how far it travels.”
3-PS2-1
“Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.”
3.MD.3
“Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories.”
3.MD.B.3
“Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step how many more and how many less problems using information presented in scaled bar graphs.”
“Use how far a car rolled as evidence of how much friction a surface has.”
“Describe everyday situations where friction is useful and where it gets in the way.”
“Name ways to reduce friction.”
RI.3.1
“Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers.”
RI.3.4
“Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 topic or subject area.”
“Explain that friction is a force that slows moving things and makes heat when surfaces rub together.”
