Our Homeschool Adventure Blog

Chronicling our adventures as a small homeschool family with mom and dad both as teachers

Honk if you love bikes!

NDEW Bike 1

One of the things I hope to do with this blog is to share some of the activities we are doing that cost little or no money. Homeschool curriculums can be expensive (although definitely worth it if you find just the right curriculum that matches your child) but you can also find lots of things to do and lots of materials to use that are inexpensive or free. One other activity like this that I’ve mentioned before is our use of the free state tourism guidebook magazines and the maps that often come with them as a part of our geography and math lessons. Another great resource is the website Teachers Pay Teachers (www.teacherspayteachers.com). While there are lots of resources that cost money on the site, there are lots of free ones too and their search feature works well.

Our latest free/inexpensive special school activity was a bike day. Last week, NDEW got a new bike so we decided to build a day’s lessons around this new bike, which NDEW was very excited about. Now, the new bike was definitely not free. Well, actually, I guess it kind of was! My parents sent me money for my birthday recently and I used it to buy us new bikes. You definitely wouldn’t have to get new bikes to do these lessons, however.

The day after we got the bikes, NDEW and hubby had to do a little adjusting on his so they used this opportunity of working on the bike to explore some questions. Here are a few examples:
•Talk about the different sizes of gears that the chain goes over. Why not the same size?
•Talk about what powers the front wheel.
•Have NDEW measure the circumference, radius, and diameter of his wheel. Have him calculate the circumference using the formula first (C= pi x diameter) and then actually measure it to see how close the formula is.
•Have NDEW figure out how many times his wheel would have to turn to ride a mile.
•Talk about metric and standard measurement using your tool set.
•Talk about how his brakes work (friction) and maybe even compare them to how the breaks on my bike work.
•Talk about why we use oil on certain parts of bikes.

Before they started working on the bikes, while hubby was getting his actual work-work done, we had NDEW read through some websites and watch some videos about bikes, bike history, and bike safety. Here are the links we used:
Websites:

Some videos:

http://www.youtube.com/watch?v=dStGTWZlZHY (Silly Bike Safety video-a little young for NDEW but just a couple of minutes long)
http://www.youtube.com/watch?v=162fCN9-qnY (A better, longer bike safety video)
http://www.sciencefriday.com/segment/04/15/2011/physics-of-the-riderless-bike.html (Another video from Science Friday about the physics of a rider-less bike)
http://www.open.edu/openlearn/science-maths-technology/engineering-and-technology/the-science-behind-the-bike (A series of videos about how science and technology have changed cycling)

Maybe this will inspire you to have a bike day of your own, our build a day of lessons around one of your child’s favorite activities. Have a great day!

I feel that I am entitled to my share of lightheartedness and there is nothing wrong with enjoying one’s self simply, like a boy. ~ Leo Tolstoy, In response to criticism for learning to ride a bicycle at age 67
