Nuts are shelled by soaking in water (salt water, probably) for 24 hours, then the nuts are boiled for 5 minutes. The boiling softens the shell, and makes cracking (by hand or machine) much easier. Nuts that are to be sold as blanched or sliced nuts, may be boiled again, before blanching and/or slicing.
A parsec is an astronomical unit of measurement that is equivalent to 3.26 light years distance, or the distance photons will travel in vacuum over the period of 3.26 years.
A parsec is a unit of light-years. A parsec equals approximately 3.3 light-years. (Keep in mind that a light-year is the distance light travels in one year â 9.5 trillion km â and that light travels 300,000 km per second!) Teacher Notes and Hints Prior to lesson â¢ Discuss and review measuring length or distance.
