True or False: When you hold an ice cube, the "coldness" moves into your hand.

. Why do metals feel hotter or colder than wood?
Metals are excellent Conductors. They transfer heat energy much more easily and quickly than wood does.
You want to keep a popsicle from melting in your backpack. Based on the "Insulators" section of your guide, should you wrap it in aluminum foil or a thick wool
sock Choice: A thick wool Sock
Write a clear experimental protocol for Experiment 1, so that it is repeatable and produces
valid and reliable results. Your answer should include a control, multiple trials,
and clear, specific steps for other scientists to repeat.
Explain how the nervous system worked to sense, process, and respond to stimuli in Lindsey's scenario. In your explanation, include the input the peripheral nervous
system receives and the output the central nervous system initiates. Lindsey sees the Squirrel. She uses the sense of sight to receive this input and sends it as a signal through
Sensory neurons to her brain. Her brain processes the information and initiates muscular movement of her arms and hands to pick up and use the camera. 10. Match the manner of spread with each illness presented in Chart 1.

In which direction does thermal energy always travel?
From Warn
. Why is the upstairs of a house usually warmer than the basement?
Because of convection, Warm air is less dense then cool air, which Causes the warm are to rise and the cool air to sink.
Explain Why (using the word "conductor" or "insulator"):
Wool is a great insulator because it traps air, which is a poor Conductor of heat. This slows down the transfer of thermal energy from the outside air into the cold popsicle, keeping it frozen longer. (Aluminum foil is a metal and acts as a conductor).
This microorganism causes strep throat. It can multiply without a host. It can be treated with antibiotics. It is so small, you would need to view it through a microscope at school.
What type of disease agent is this microorganism?
a. Virus
b. Fungus
c. Bacteria
d. This microorganism is not a disease agent.
A patient comes to you with complaints of pain, tingling, and numbness in her left foot.
The patient has no problems with movement. Brain scans, CSF, and EMG tests were all normal.
Nerve conduction velocity tests were abnormal.
Scenario: You place a hot boiled egg into a bowl of cold water. Describe the energy transfer:
Energy moves from the Egg to the Water.
The Blanket Myth: Why won't a blanket make a plastic doll feel warm?
. Blankets don't generate heat; they only trap heat from a worm source.
. Many cases of patients with similar symptoms are being admitted to a local emergency room. It is believed that these patients are sick from a foodborne illness outbreak caused by a bacterial disease agent that leads to problems with the nervous system. How would an ER doctor, a neurologist, a microbiologist, and an epidemiologist work together to help these patients and prevent future cases?
ER Doc & neurologist work to diagnose and treat the patient. Microbiologists would confirm the presence of bacteria ar Cletermine the best antibiotic to use. The Epidemiologist would investigate patterns to identify the Sarce of outbreak and prevent further illness.
What functions might be affected in a patient with a tumor in the occipital lobe?
a. Behavior and personality, such as planning, initiated movements, social and
emotional processing, and attention.
b. Sensing touch, spatial processing, language, and memory.
Visual perception and some forms of visual short-term memory.
This information leads you to believe the problem is in the peripheral nervous system. Given the choices below, which structure is the most likely location of the problem?
a Sensory neurons
b. Motor neurons
c. Brain
d. Spinal cord

The Equilibrium Test: You leave a metal plate and a plastic plate in a freezer overnight.
Which one is at a lower temperature? Neither; they're the same temperature Why does the metal feel colder? It's a better conductor and moves heat Away hand faster than plastic does. from your
A group of students performed an experiment to see whether running in place for two minutes or being in a hot room would increase body temperature.
They had five students sit in a chair for two minutes and then measured their body temperature.
They had the same five students run in place for two minutes in a hot room and then measured their body temperature after running.
They repeated the experiment three
Given the attack rates shown in Table 1, which food item is the most likely source of the illness that's causing several students to get sick?
a Sausage
b. Butter
c. Milk
d. Juice

. What was wrong with Experiment 1?
a. They didn't include a control group.
b. They didn't include multiple trials.
C. They included more than one independent variables.
They should've only had one test subject.
. A patient comes to you with complaints of intense headaches on the left side of his head just behind his eye. He also tells you that lately he has had trouble concentrating and feels unusually angry and confused. You ordered a variety of diagnostic tests and have the following results:
Patient's speech, hearing, and vision appear normal.
Patient's ability to perform memory tasks is less than expected for his age.
Patient's ability to control movement and balance appear normal.
Several students came to the office with stomach aches and vomiting a few hours after a pancake breakfast. A foodborne illness was suspected for the outbreak, and students were interviewed about the food they ate earlier that day.
