WEDNESDAY AUGUST 5, 2007

2ND GRADE HISTORY - learned about Roman roads made from cement. They also used cement to build apartments, aquaducts, sewers and public baths. Learned about how the Romans built aquaducts to bring clean water to the city and sewers to take out the dirty water. The boys were fascinated by this - if anyone has a book that shows these it would be great to show them. We talked about how people used to just throw waste water out the window - led to a long discussion of hygiene. Also, we learned about Roman numerals (how we still use them) and the Roman social structure; patricians - rich, plebeians- workers/merchants, and slaves (allowed to buy their freedom sometimes.) Great discussion about this. Made coins, built aquaduct, shops, sewer pipes and road signposts.

2ND GRADE SCIENCE - used a spring scale to measure objects in newtons. they had fun with this. Exciting discussion about the difference between weight and mass - weight is measurement of earth's gravity pulling on an objects' mass - mass is measurment of the "stuff" an object is made of. Used a trip to the moon to explain. Very fun and excited discussion about weightlessness followed. The cards they cut out would be good to keep for periodic review.

Good day! Rachelle
