Grades 68  10 (45 min) Classes
In this unit, students will use algebraic equations and expressions to make sense of what effect different masses have on the velocity and acceleration of different model rockets. They will answer the question, “How are algebraic equations used to calculate model rocket acceleration?” and will learn how to calculate altitude, velocity, and acceleration using basic algebraic equations of motion.
For their final assessment, students will create a bar graph of the average acceleration for each of the three rockets (Alpha, Generic E2X, and Viking) and reflect on the effect of the mass of the rocket on acceleration.
Standards
Common Core Standards  Math
GRADE 6
CCSS.MATH.CONTENT.6.EE.A.1
Write and evaluate numerical expressions involving wholenumber exponents.
CCSS.MATH.CONTENT.6.EE.A.2
Write, read, and evaluate expressions in which letters stand for numbers.
CCSS.MATH.CONTENT.6.EE.A.2.A
Write expressions that record operations with numbers and with letters standing for numbers.
CCSS.MATH.CONTENT.6.EE.A.2.B
Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity.
CCSS.MATH.CONTENT.6.EE.A.2.C
Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in realworld problems. Perform arithmetic operations, including those involving wholenumber exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
CCSS.MATH.CONTENT.6.EE.B.5
Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
CCSS.MATH.CONTENT.6.EE.B.6
Use variables to represent numbers and write expressions when solving a realworld or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
CCSS.MATH.CONTENT.6.EE.B.7
Solve realworld and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.
CCSS.MATH.CONTENT.6.EE.C.9
Use variables to represent two quantities in a realworld problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables and relate these to the equation.
GRADE 7
CCSS.MATH.CONTENT.7.EE.A.1
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
CCSS.MATH.CONTENT.7.EE.B.3
Solve multistep reallife and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies.
CCSS.MATH.CONTENT.7.EE.B.4
Use variables to represent quantities in a realworld or mathematical problem and construct simple equations and inequalities to solve problems by reasoning about the quantities.
CCSS.MATH.CONTENT.7.EE.B.4.A
Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.
GRADE 8
CCSS.MATH.CONTENT.8.EE.B.5
Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.
CCSS.MATH.CONTENT.8.EE.C.7
Solve linear equations in one variable.
Common Core Standards  ELA
CCSS.ELALITERACY.RST.68.3
Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
