NOVA: Design a Parachute

What it is: NOVA from PBS has an excellent interactive called Design a Parachute.  In this activity, students take on the role of head engineer in charge of designing the Mars Explorer Rover parachute.  The goal is to design a chute that will get the Mars Explorer Rover to the surface of Mars safely.  The interactive challenges students to consider trade-offs in parachute stability, strength and volume as they design the perfect chute.  As students begin the activity, they are briefed on system requirements that must be met.  Students are also asked to consider cost as they design their parachute.  Finally students design and test their chute. How to integrate the NOVA Design a Parachute interactive into the classroom: In this activity, students assume the role of engineer as they design a parachute that will slow the Mars Explorer Rover as it lands on the surface of Mars.  I like the authentic feel of this activity, students are led through the thinking process of an engineer as they consider all of the requirements the chute must meet before they begin designing. Approach this interactive as a class using an interactive whiteboard or projector-connected computer.  As a class, get “briefed” on the requirements for the parachute design.  Discuss how these requirements may impact the parachute design.  Treat this like an actual briefing and encourage discussion (all ages like to pretend!).  Before students access the interactive, ask them to sketch their thoughts about parachute design.  This lets them think through the design apart from the pre-determined categories presented in the interactive. Students can design and test their parachutes individually in a one to one computer lab setting or take turns designing and testing in a computer center lab on classroom computers. Debrief after the interactive to discuss the parameters that were the most successful and what students learned about volume, drag, strength and stability. Extend this activity by creating a mock-up of the parachute they designed online.  Find a high place on the playground or in the building where students can test these parachutes.  What did they have to adjust for an Earth bound parachute? Tips: The NOVA page has a great introduction paragraph about how engineers approach a problem.  Be sure to read it with your students!  Encourage students to learn more about the Mars Explorer Rover before designing the chute.  It may adjust their thinking!

iLearn Technology Oxford Owl Math ebooksWhat it is: Oxford Owl is the awesome site I wrote about yesterday.  They have a fantastic collection of free ebooks and accompanying activities for kids.  The site is making an appearance in today’s post because they ALSO have Oxford Owl Math for ages 3-7.  There isn’t quite the breadth of resources here that you will find on the main Oxford Owl site, but they do have some great suggestions for math activities, both online and offline, and there are some online math e-books.  The 3-5 section currently has the most e-books, online math games, activity sheets that can be printed out, and offline games to play.

How to integrate Oxford Owl Maths into the classroom:  Oxford Owl Maths has some wonderful math themed interactive ebooks that include practice with position words, counting, shapes, time, and adding/subtracting.  The ebooks make for a great introduction or review in the kindergarten and first grade classrooms.  The telling time ebook and activities are even appropriate for second grade students.  In the kids treasure box, students can collect online trophies for the games and puzzles they complete, find recipes to make in the kitchen, and download offline activities.

Oxford Owl would be a nice center activity that even the youngest students could explore independently or with a partner.  It could also be used for whole class stories with an interactive whiteboard or projector.

This is a good site to introduce parents to for at home reading, play and math practice.  If you have a classroom website, Oxford Owl is a great one to link to!

Tips: If you haven’t already, be sure to check out the Oxford Owl Literacy site.
