Bile is the substance secreted by the gall bladder to aid the break down of fats into an emulsion. Bile is not an enzyme. It only causes the fat to emulsify. In this experiment, you will use soap to break up the oil. In this experiment, you will observe the emulsification of fat in milk. This is a model of how bile emulsifies fat in your digestive system. The soap is used in place of bile.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
