The Physics of Angry Birds Space explained



 

Angry Birds Space is the newest version of the extremely popular game and it is as fun and addicting as the other versions.

I have always thought that games made an excellent learning tool when done right, with the right support by the teacher. Many video games teach students actual content knowledge, but most of them teach critical thinking and problem solving techniques. Research has shown that video games are effective as learning tools and many companies are working on educational video games. But, other video games can be used educationally also.

I love Angry Birds. I've have played, and solved, every version of the game and every level. It's one of those games you can't put down. I've played on my old Palm Pre+, my HP TouchPad, my Droid Incredible 2, and even on Chrome. My students and I are always talking about the new levels and how to solve them. I also use it in my Physics class to allow students to have fun while investigating forces, motion, momentum, angles and projectile motion. They have to analyze the problem and think through solutions. They learn and have fun.

Each time someone talks about using Angry Birds as an educational tool, there is someone else talking about it's errors or inaccuracies. It's actually built using a very good and accurate physics engine, so it is a great educational tool. But, Angry Birds Space has a whole new part to it - variable gravity fields. While some have said that it is inaccurate, I think it is just being creative. There are bubbles around the space objects that have different gravitational and frictional effects. They are not true examples of how gravity works around an object, but are fun and different and can be used as an educational tool.



Rhett Allain, a writer at Wired Magazine, has analyzed the physics of Angry Birds Space and "has now calculated the forces that act within the bubble-like region outside asteroids. After going through the first level, Allain found a constant force that acts as a sort of gravitational pull, along with a constant frictional force that pulls in the opposite direction as the bird's velocity. The birds are launched at a similar speed as on Earth (25 m/s in space as opposed to 23 m/s), but Allain suspects they get a slight speed boost as they enter the "air" around the asteroid. You can go ahead and read the source to see his work, which includes both calculations of the birds' potential energy and scripted models that mimic the motion of a red bird in orbit."

National Wildlife Federation resources for Educators


National Wildlife Federation

The National Wildlife Federation (NWF) has some great resources for educators on their web site. There is a news section, wildlife animal information and resources, environment and global climate change resources, and much more.


Bald Eagle

They have wildlife cameras that you can view, such as the Eagle Cam, an incredible Wildlife Library with information about different animals and species, and Wild Places where you can virtually visit and explore some great wild parts of America.

There are outdoor activity guides and things to do outside, Wildlife news reports, and Global Climate Change resources.

Kids Banner

The Kids Page is well done also, explaining topics with children in mind, animations, videos, explanations, and even mobile apps.


The NWF also offers free webinars on a variety of topics.


This is a great resource for teachers and students to use when studying wildlife, nature, and the environment.






Google Art Project Expanded to over 30,000 images and 46 museums


The Google Art Project is a great resource for students and educators that I reviewed last year. It was originally a small collection of artwork from museums set up as a virtual art museum, where you could take virtual tours and even create your own "collections of art." It has now been expanded to include paintings, sculpture, street art and photographs from 151 museums in 40 countries.

The original Art Project was 17 museums, in 9 countries, with 1,000 images, mainly paintings. The new expansion brings the Art Project up to over 30,000 hi-res images and even Street View images for 46 museums from around the world.

Here are some of the new features:
  • Using completely new tools, called Explore and Discover, you can find artworks by period, artist or type of artwork, displaying works from different museums around the world.
  • Google+ and Hangouts are integrated on the site, enabling you to create even more engaging personal galleries.
  • Street View images are now displayed in finer quality. A specially designed Street View “trolley” took 360-degree images of the interior of selected galleries which were then stitched together, enabling smooth navigation of more than 385 rooms within the museums. You can also explore the gallery interiors directly from withinStreet View in Google Maps.
  • We now have 46 artworks available with our “gigapixel” photo capturing technology, photographed in extraordinary detail using super high resolution so you can study details of the brushwork and patina that would be impossible to see with the naked eye.
  • An enhanced My Gallery feature lets you select any of the 30,000 artworks—along with your favorite details—to build your own personalized gallery. You can add comments to each painting and share the whole collection with friends and family. (It’s an ideal tool for students.) 
Here is a video on how to use the Art Project site:

For more information and future developments, follow the Art Project on Google+

This is a great resource for students and educators. Image being able to view such incredible works of arts and museums right from your classroom without the hassle and cost of airfare, TSA security, buses, cabbies, and the like! There is even an Education section on the site.

Summary of new teacher tips, urban schools issues, technology resources




This past Saturday I spoke with the pre-service science teachers in Connecticut's Alternate Route to Certification program about new teacher tips, urban schools issues, and technology resources.

Here is the handout I gave them as we chatted.



ARC-A-Palooza 2012
David Andrade, M.S. Ed

New teacher stuff

  • ask for help
  • lots of resources online - lesson plans, classroom management, activities, new teacher help
  • remember what you have learned here
  • be organized!!!  (Evernote, Google Docs, Google Calendar)
  • take advantage of professional development opportunities and find some outside of district
  • join a professional society (NSTA, AAPT, etc)
  • use Projects in your classroom
  • Have a backup plan and be creative

Resources, Links and Articles to read:
 
Urban/low income schools
Student issues
not all students think school is importantno support at home (hmwk, etc)
no parents, too many kids, no parental involvementpoverty, drugs, violence (HS kids work to pay bills)
work part time jobs to help pay billsno ride to school
issues at home - absences, tardytake care of siblings
no computer/internet at homecultural beliefs are different
high turnover of students (pregnancy, crime, drugs)move a lot - change schools
English as Second LanguageReading comprehension


School Issues:
high teacher/admin turnover and burnoutlarge classes
limited funds and resourceshard to change things due to lack of resources
lots of new teacherslots of new initiatives to fix (don't work)


Things to do to help and support urban students:
give students time to do work in schoolmake  your classroom available after school
create a safe haven in your classroombe sensitive to issues they face
remember cultural/socio-economic issuesconnect learning to THEIR lives and experiences
look for grants (www.donorschoose.orgcreate a PLN for ideas and resources (see below)
connect with business, colleges, and other schoolsEnthusiasm is contagious! Engage & Excite them.
translation (Google translate)differentiate and individualize






What advice do you have for new teachers, teachers going to urban districts?

Student scholarship of $3000 available from Shmoop and Zinch

 


Shmoop, a site that provides resources and information to help "make learning and writing more fun and relevant", and Zinch, a site with college admissions and search help for students, are offering a $3000 scholarship for US students. Students simple enter by competing an online form. The deadline to enter is May 31st. 

While $3000 may not seem like much with tuition costs for some colleges averaging over $50,000 a year, any thing helps!

PicMonkey - free online photo editing


PicMonkey is a service I learned about from Dave Kapuler that is an easy to use, free, online photo editing service.

PicMonkey is very easy to use. Simply upload or drag and drop a photo onto the site and edit away.

It was created by some former Picnik engineers and is a great resource, touting itself as faster and more powerful than Picnik. And, Picnik is shutting down, so this is a great replacement.

You can crop, rotate, add effects, add borders and text, and manipulate photos with some very powerful and useful editing tools, all online.
