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!

Solar Car Racing: Try Engineering

What it is: Solar Car Racing is a great game and challenge from Try Engineering.  On the Solar Car Racing games students will virtually design and race a solar car.  Students begin by choosing the components for their car that will optimize the performance.  Next they test out their car in a desert and on a racetrack environment to find out how it performs.  Students can observe the performance and then modify their design based on feedback and race again.

How to integrate the Solar Car Racing game into the classroom: Try Engineering has some really fantastic interactive games for students.  I like Solar Car Racing because it goes beyond just building and testing, and encourages students to learn from their mistakes to modify their design.  Too often games created for students have a defined end point that doesn’t encourage students to continue tinkering and experimenting.  Solar Car Racing would make a good “experiment” center on classroom computers.  Students can stop by the “lab” area as they are learning about solar energy to test out the principles they are learning.

Ideally, students would each have access to the site.  This would allow each student to create and test a solar car design.  Let students discuss observations of what designs work best and why.  Students can “sell” their solar car design to each other. Expand this activity by asking students to create a sales brochure for their solar car.  Students can include researched information about solar cars, tout unique elements of their design and practice persuasive writing and design.

If students don’t have access to their own computers, make this a class activity using a projector-connected computer or interactive whiteboard.  Give each student the opportunity to tweak and test the design, discussing adjustments and possible outcomes as a class.

If you have the resources, perfect the solar car design using the Solar Car Racing game and follow-up by creating an actual working model size version.

Tips: Be sure to check out the fantastic list of related links at the bottom of the Try Engineering Solar Car Racing page.

Science

What it is: Macmillan-McGraw Hill Science is the online student addition of the textbooks. Students is grades kindergarten through six can click on the book that matches their grade level. Here students can watch video clips, play vocabulary games, take animated summary quizzes, read e-journals, and more.

How to integrate Macmillan-McGraw Hill Science into the classroom: Even if your school does not use the Macmillan-McGraw Hill Science textbooks, this site is a wonderful supplement to any science curriculum. The fun interactive environment is sure to be a hit with students. The vocabulary review games would be fun to play as a whole class with the projector (split students into teams) or individually. You might also offer this site to students for homework help or for test review at home.

Tips: Click on the OSE button at the bottom of the screen for the Online Student edition of the text box. Below the OSE button are login names and passwords for various grade levels.
