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!

What it is: Count Us In is a fun basic math skill site with 15 interactive games that teach kids basic math skills. These include counting, patterning, counting, ordinal numbers, representing number with words, addition, subtraction, sorting and grouping, time, numbers, chance, halves, length, and volume. The flash based games can be played online or downloaded to a Mac or PC for offline play.

How to integrate Count Us In into the classroom:
These are great games to teach kids basic math concepts. The site is good for individual use in a computer lab, or center group use in a classroom setting. Students can work at their own level, going onto the next game after they have mastered one. The games can be used to help teach concepts or as review and practice for math skills. The site is best for k-1 students or struggling math students in second grade. The site is also perfect for an interactive whiteboard. Call students up to the board to interact with the games individually or split your class into teams to play the games.

Tips: Visit the “other activities” section of the Count Us In website for some great teacher resources including well thought out activities to use with the games on the website.

Cyberchase

What it is: Cyberchase is a website aimed at teaching kids that math is everywhere, that everyone can be good at it, and that math can be fun. The Cyberchase website is based on the PBS TV show, teachers can view episode guides, video clips, and character descriptions. The website has two main sections for math enhancement, games and quests. Games include interactive math games and puzzles. Quests are interactive games that allow students to create their own cyber characters and go on cyber quests. Math topics include measurement, patterns, deductive reasoning, saving, spending, budgeting, making hard problems easier, growth by doubling, inverse operations, decimals, negative numbers, combinations, place value, elapsed time, angle measurement, linear measurement, timekeeping, area, volume, bar graphs, equivalent fractions, fractions, data clusters, probability, algebraic thinking, perimeter/area relationship, patterns in music, scale and size, patterns, codes, functions, estimation, counter examples, logic, point of view, using models, 2d and 3d geometry, navigation, symmetry, navigation, proportional thinking, circles, and percents.

How to integrate Cyberchase into the classroom: Cyberchase is an incredible website! With the number of math topics, there is a game to fit every curriculum. The games are fun, interactive and teach critical thinking skills. Students experience math when they use the games and quests. This site really makes math come alive! Use this site to introduce new math concepts (students probably won’t realize that they have learned a new math concept until you dissect it for them afterwards!) The site would also be great to reinforce math concepts that have already be learned. The games and quests make an excellent practice field. Games could be used with the whole class and a projector cart (be ready for a lot of volunteers on this one!) Or individually as a math center or all at once in the computer lab setting.

Tips: Visit the Cyberchase teachers page for lesson plans using the Cyberchase games. This is an outstanding math resource! Even your most resistant math students will love this site!
