When You're Hot, You're Hot! When Your Not...

...go back inside!

I the course of two weeks we went from -20 F to 50 F here in southwest Minnesota! That got me and the kids thinking about temperatures. We often have "guess the temp" contests when we drive past the bank. which displays the temperature in both F and C. DJ's guess was a bit off for for F, but right on in C.

Then we wondered, "is there any temperature that is the same number in both measuring system.  That is today's challenge: Using only the formula for temp conversion, find the temperature that is the same in both Fahrenheit and Celsius.

Here is the formula: F =  C x 9/5 + 32
Or the other way around: C = (F - 32) x 5/9

This will take some 'guess and check' but you can do whatever you put your mind to.

By the way, the Robotics Expo was awesome!

Nebraska Robotics Expo & First Lego League Championship

Nebraska Robotics Expo: First Lego League Championship and Jr. First Lego League Fair

on Saturday, February 19, 2011, Strategic Air and Space Museum, Ashland, NE

We will be attending this event at the SAC Museum! YEAH! Thanks to no school on Feb. 21, we will definitely attend!!!
The boys did LEGO Robotics in 4-H and had a very fun time programming and building the bots.

While at the SAC, we will be seeing: Anakin Skywalker's Podracer exhibit. 


More about First Lego League found here from Univ. of Nebraska and 4-H:

GEAR-Tech-21 is a geo-spatial and robotics 4-H program available to middle school-aged youth throughout the United States.  Using LEGO MINDSTORMS NXT® robotics kits and handheld GPS devices, youth can experience science, engineering and technology career areas through camps, club programs and competitions.  Designed with the experiential learning model, all activities have a hands-on problem-solving focus.
GEAR-Tech-21 is an innovative curriculum that brings together robotics, GPS (Global Positioning Systems) and GIS (Geographic Information Systems). Through this program, youth will:
  • Build and program robots
  • Operate a handheld GPS receiver
  • Put your science, technology, engineering, and math skills to work
  • Explore the outdoors
  • Apply robotics, GPS, and GIS technologies to geo-tracking, navigation, and mapmaking
  • Learn about the role of information technology in natural resources and precision agriculture
  • Find out about careers in science, technology, engineering, and mathematics including robotics, GPS/GIS, natural resource management and agricultural technology
  • Complete fun challenges and have the opportunity to compete in a virtual competition with other youth across the country.
  • Prepare to compete in a FIRST LEGO League®, GEAR-Tech-21 or local competition.

The program is designed to be very flexible for groups to adapt to various schedules, interests and other constraints.  Ideally, a youth would begin GEAR-Tech-21 programming with a one-week introductory camp followed by an academic year of regular club sessions including one or more competitions.  Advanced youth would repeat the process for the second year with an advanced camp and advanced club activities.  Because of the program's flexibility, the curriculum can be adapted for classroom, after school or community club formats.
A key component to GEAR-Tech-21 is adult volunteers.  Adult volunteers lead camps, club sessions and coach teams for competitions.  They may or may not have technical expertise prior to leading a GEAR-Tech-21 group.  In addition to online leader guides for each activity, leaders have face-to-face training, online training and online leader forums to access support.
As a part of 4-H, participants can access hundreds of other experiences through additional project areas, camps and more.  By contacting your local Extension office, you can learn about other opportunities in your area.

The Super Bowl Puzzle Answer

After much discussion, and clarification (the question stated on offensive points) we have come to the conclusion that 5 is the highest score that an NFL team could NOT achieve playing offense. I am not certain that is all, but with the help of Matt, I believe this is the correct answer.

Thanks for joining the discussion.

The 'What's the Highest Score an NFL Team Could NOT Earn in the Super Bowl?' Puzzle

I am not nearly as interested in the Super Bowl as my kids.  One thing I do enjoy is trivia or number challenges. Here is a combination of the two: a football number challenge.

What is the HIGHEST score an NFL team could NOT in the Super Bowl while playing on offense (meaning no Safeties, which is a defensive score). Assume that there is NO TIME LIMIT to this game.
The only ways to score are:
• TOUCHDOWN
• FIELD GOAL
• 1-EXTRA-POINT CONVERSION (can only be earned after a touchdown)
• 2-EXTRA-POINT CONVERSION (can only be earned after a touchdown)

No Googling the answer, as I am certain someone has already worked it out. Instead, see how close you can get. I will be working on it as well, as I do not yet know the answer.

Post your answer in the COMMENTS, and I will keep them hidden for some time so everyone can try it out for themselves.

Time will tell...

Isaiah, who is in Kindergarten, is learning to tell time. He seems to be doing well, but it has reminded me of teaching "time" when I was a Kindergarten teacher.

This may take same serious reminiscing, but what do you remember about learning to tell time?
How old were you? What grade were you in?
Did you use both analog clocks and digital clocks?
What challenges did you have?

Coincidentally, I am writing a unit for teaching kids to tell time. In my opinion, some textbook companies go about it backwards and end up skipping crucial steps.

What is your experience?
I will post more when I have my Time unit closer to completion.
