History

The Midnight Ride of Paul Revere

Paul Revere, famous American revolution patriot, is most remembered today for his night-time ride before the battles of Lexington and Concord. His famous “Midnight ride” took place on the night of April 18, 1775 – exactly 244 years ago next Thursday. William Dawes and Revere were instructed by Dr. Joseph Warren to ride from Boston to Lexington to warn John Hancock and Samuel Adams of the movements of the British Army. Today’s  resources celebrate both the man and the events of that night.

Listen My Children (MP3 audio) – FIRST UP up this a great half hour audio story about Revere’s life and influence,including the events of that fateful night, as originally dramatized on the radio program “Cavalcade of America”, in December, 1952.

Physics & Science Fair Experiments

Today we feature these neat collections of physics experiments & demonstrations for kids, from Real World Physics Problems.com. This site contains lots of interesting physics problems, complete with solutions, taken from real world applications — but today we are pointing you to the “hands-on” fun stuff:

First is a collection of fun and interesting science experiments which kids of all ages can do at home. These are fun experiments which are easy to do and don’t require a lot of time. These experiments are mostly physics based. Click here for the experiments for kids.

Then, on their Science Fair Project page, you will find several ideas for cool science fair projects for kids of all ages. These projects are particularly interesting because they have practical relevance in real life, and you can use common everyday materials to create them. Click here to view them.

Math

The Arithmetic Primer

Today we have this excellent vintage arithmetic primer by Frank Hall for grades 1 and 2, outlining two full years of concepts, lessons and examples for younger students.

From the introduction:

The Primer of Arithmetic is not made up mainly of graded miscellaneous problems. It is built on a plan. Each four-page group constitutes the larger unit of the plan. Twenty-seven presentations of this gradually changing unit make up the book. In the first eleven groups the page units are as follows:
1st page – New number facts
2nd page – Number facts applied to linear measurements
3rd page – Number facts applied to surface measurements
4th page – The “Elementary Spiral” (a problem in each of the five fundamental processes), followed by miscellaneous problems
In the remainder of the book, the 1st and 4th pages of each group are similar to the corresponding pages of the first eleven groups. The 2nd page teaches the application of primary facts to the larger numbers. The 3rd page deals with solid, surface, linear, and capacity measurements.

Great guide for introducing arithmetic to primary students!
