SOMEONE ANSWER. :(((((((((( please? :(
One way is to refer to a model of the alimentary canal. Your biology lab probably has one.
One physical science (ex: chemistry, astronomy, physics, etc) and one physical science (ex: physiology, biology, human biology, etc.) One must be a lab.

You will need a small electrical multi-tester to test the switch. Set the tester to "ohms". Disconnect the wiring from the switch. Touch one of the tester leads to one side of the switch and the other lead to the other side. Your reading should be zero. Have a friend depress the brake pedal, and the needle on the meter should swing left to right. If the needle does not swing then the switch is bad. If it swings then the problem is elsewhere in the wiring. The multi-tester can be found at hardware stores, auto parts stores and department stores.
One can purchase a robin loop tester from Ebay. One can also purchase a robin loop tester from electrical shops or from electrical dealers which carry robin loop testers.
A pH tester is used to determine the acidity or alkalinity of a substance. One can purchase a pH tester online at websites including Home Depot, Amazon and Sears.
Check with the biology, geology, or engineering department of local universities. They may allow you to use one, with the supervision and assitance of a technician or lab manager, for a fee.
One can purchase a gold tester from the Jewelry Tools website, which sells a high quality and well rated tester. The tester is currently being sold for about one hundred and ninety dollars.
One could purchase a portable hardness tester at MCS Direct, and on Amazon. Another place to purchase a portable hardness tester online would be Martrow which offers free shipping in the United States.
In the lab, the precision of touch is often tested using methods like two-point discrimination, where the smallest distance between two points that can be accurately perceived by touch is measured. This typically involves using a two-point caliper or discriminator to apply stimuli of varying distances on the skin, and the participant's ability to differentiate between one or two points is assessed.
The simplest type is just two wires with a small light in the handle. Touch one lead to a ground and the other to the positive you are checking. If there is power in the contact, the light will come on. It should be around $4.
Need to know what you are testing to answer that one.
