Thursday I posted about this great book we discovered at the library, Dinosaur Discovery. (I meant to post this on Friday, but got caught up in making a really fun LEGO/dinosaur party come together for Cutie Pie’s 6th birthday…sorry!) This great book contains a lot of dinosaur information that we haven’t come across in other books about dinosaurs, or perhaps just not in such a simple and attractive way. As I shared yesterday, this book also contains some really neat experiments! (Simple enough to do with a preschooler on up!)
Sweet Pea, Cutie Pie and I tried the ‘Standing Up to Force’ experiment about skeletons being built “to take the forces pushing and pulling against them, without breaking.” The experiment describes sitting on a table because it has legs positioned strategically to support the force of the tabletop pushing down on it. The bones in dinosaurs are no different.
Quite simply, take two toilet paper rolls, stand one up in its end. Carefully set one book at a time on the roll that’s standing up, balancing them with your hand if necessary. How many can it hold before collapsing?
Now take the other roll and set it on its side. Stack the books on it one at a time, holding the bottom book to keep it in place. How many can this one hold?
What is the difference between the two?
Can you figure out how dinosaur bones are similar to the toilet paper roll standing up?
See, isn’t this so simple and fun? For more really fun experiments check out the book!
|According to Cutie Pie the T-Rex rules the roll|
