  • Rapeseed (Brassica napus subsp. napus), also known as rape and oilseed rape and canola, is a bright-yellow flowering member of the family Brassicaceae (mustard or cabbage family), cultivated mainly for its oil-rich seed, which naturally contains appreciable amounts of mildly toxic erucic acid.[2] The term “canola” denotes a group of rapeseed cultivars that were bred to have very low levels of erucic acid and which are especially prized for use as human and animal food. Rapeseed is the third-largest source of vegetable oil and the second-largest source of protein meal in the world.[3][4]

    We call it Sunflower Oil

    We call it Rapeseed Oil

    Not Rape Seed Oil











  • This is part of common core math

    Making Tens (and Hundreds): Composing and decomposing: Students learn to break down numbers to make friendly numbers like 10 or 100, which are easier to add. Example: To add 8 + 5, they might see that 8 needs 2 to make 10. They could take 2 from the 5, leaving 3. Then, they add 8 + 2 = 10, and 10 + 3 = 13.

  • Insulation on the dishwasher is mostly for noise and stopping moisture or heat from damaging surrounding cabinets.

    The dishwasher is using new water or heating water. It is not designed to keep the same water hot for an hour plus.

    The whole back of the dishwasher is a tiny piece of plastic. Not insulated at all. Some fancy ones now put a little insulation on back.

    But the idea isn’t to keep heat trapped to wash dishes, but to keep heat from being released and damaging things.
