We’ve updated this activity and thought that we should mention it again as we approach the Academy Awards. In this investigation, Brian looks at the changes in movie ticket prices over the last 30 years. Using his scatter plot (or his data) students analyze rates of change, make predictions about the future ticket costs, guesses about past costs and try to create lines of best fit. Or check out any of our other five movie themed lessons below.
Let your students play this great game online at Ghost Whisperer Crystal Ball and
- Figure out why it works.
- Construct viable arguments
- Critique the work of others
Will we have a 29th of February this year? How can you tell?
Students work with a flow chart to deduce what years are going to be leap years. They learn about the exact measurement of a solar year and how our Gregorian calendar needs to be adjusted to align our calendar with the sun’s rotation.
Let your students develop their own ideas about compounded percent change while they have the opportunity to speak about the upcoming Academy Awards show.
Worldwide box office income is compared for the top ten grossing movies of all time. Is total gross the most appropriate way to judge the popularity of a movie? How does inflation and increasing ticket prices come into play? Inflation rates are used to let students calculate how the money of 1997 compares to the money of 2013. The idea of this comparison is to encourage students to develop their own understanding of exponential growth.
This activity is accessible to students as young as 5th or 6th grade once they have become familiar with computing with exponents and percents. The activity is appropriate for middle schoolers and high schoolers as well by allowing students to generalize a formula for finding the adjusted-for-inflation earnings of any movie.
Friction, score-keeping, trajectory and weirdness are the main concepts in this activity. Curling is not a well-understood sport but the science and strategy are easily understood and enjoyed.
Let your students watch this video to get a feel for the sport before they try the activity.
Another great week!
