//Emulsion//: An emulsion is a mixture of 2 liquids that are unblendable. In an emulsion, one liquid (dispered phase) is mixed into the other liquid. An example of an emulsion is salad dressing as you can still see the vinegar in the olive oil when it is still in a the bottlle. This make salad dressing an emulsion because the two liquids are unable to fully mix together.
 * __Colloids__**.

A. Two immiscible liquids, not yet emulsified. B. An emulsion of Phase II dispersed in Phase I. C. The unstable emulsion progressively separates. D. The surfactant (purple outline around particles) positions itself on the interfaces between Phase II and Phase I, stabilizing the emulsion.

The most bending of light happens in the lens.
 * Can you trust your senses?**
 * 1. Where does the most bending of the light occur in the eye?**

The lens moves depending on what your eye is trying to focus on.
 * 2. Describe how the lens works**

We squint when we are exposed to bright light because when it is dark, our pupils get bigger to let in as much light as possible. We squint when we are exposed to bright light because then we don't need as much light to see.
 * 3. Why do we squint when exposed to bright light?**

The lens and the iris are involved in focusing.
 * 4. Which parts of the eye are involved in focusing?**

The implications of losing one eye is that it would make your brain confused because you would only have one optic nerve connecting to only one eye.
 * 5. Discuss the implications of losing one eye.**

//Discuss: Visual impairment// //Do you know anyone who wears glasses or contacts? Why? How do glass or contacts help?// I know people who are visually impaired for many different reasons. Such as, the shape of the eye ball, diseases and accidents. Glasses and contacts help by spreading light out or bringing light in. //Are there other solutions for people with visual impairments?// Other solutions for visual impairments is laser surgery.
 * Student task Two**

//-describe two visual impairments. Describe some possible solutions.// Short sighted - the light stops before it hits your retina. A solution is lenses that spreads light out. Long sighted - the light extending past the retina. Solutions could be lenses that bring light in.
 * Use the resource from the last section to find out about visual impairments**


 * Animal Senses**



Bats have a special sense called ecolocation. They use ecolocation to navigate their surroundings. They make a high frequency noise, which then echoes off objects. The brain and ears help make an image of what is their surroundings. An undeveloped sense for bats is their sight. This is probably because they live in dark places.
