Lego Robotics-Team Mobots

After weeks and weeks of practice Sam's team was finally able to put all the tweaking and testing to work.  Their robot followed the line perfectly!

McLean Elementary STEM (Science Technology Engineering Math) Fair Entries

 Both boys chose topics close to their hearts. Ben wrote an entire Background article that began with the start of Ben ink (the company he founded) and how he had so many crayons to peel, he needed to find a faster method to remove the paper.  He used 14 different objects to peel the paper and we timed the results. He predicted that an item with a blade would be the most effective, and 2 of the top 5 fastest times were bladed items.
Sam chose to study the properties of acceleration based on his love of Hot wheels. Doug and Sam worked together to find out how long it took 3 different models of cars to go from 0-70 and found the rate of acceleration. Doug helped Sam build a wood model that pulled back and would launch a hot wheels car to demonstrate the acceleration
Ben won 1st place among his 2nd grade classmates. So proud of both boys.

A winter blast

After two weekends of raking leaves we needed a break.  It snowed about 3-4 inches.  The snow was awesome for a snow man.

Brotherly love with snow balls.


Sledding fun on Saturday.
