2. What happens to the coloured water around the crystal when the heating begins?
When the water is heated it rises.
3. What happens to the coloured water near the surface of the water?
The coloured water near the surface begins to move in a circle in the Pyrex dish. It sinks in the part that is not being warmed by the burner..
Assignment 7:
(Groupwork)
When a see breeze is caused by convection, your group should be able to work out how a land breeze occurs. Make sketches and write your explanation here.
How does a land breeze occur?
During the night the land cools more quickly than the sea. The sea stays warm longer than the land. The warm air above the sea rises. Cooler air from the land blows towards the sea
Assignment 8:
1. What happens when you place the pane of glass in front of the heater?
Immediately you feel less heat.
(The heater / source of heat is not warm enough. Glass obstructs radiated heat from the heater, just like wood or cardboard)
Assignment 9:
1. Does your hand immediately feel the heat?
Yes
2. How does the heat reach your hand?
Through radiation.
3. Does the glass of the bulb prevent radiance?
No, because the radiation from a very warm (white hot) object can penetrate glass.
Explanation: Water conducts electricity and if you touch an electrical appliance while you are standing on the ground the current flows through your body to the ground. This can cause a fatal shock.

4. MATERIALS CAN TRANSFER HEAT
If you hold a teaspoon in boiling water it feels warm when you touch it. Heat has thus been transferred from the water to the teaspoon. (This transfer of heat will not happen if both substances are the same temperature.)
Transfer of heat takes place in three ways: Conduction, convection and radiation.
4.1 Conduction:
This is the transfer of heat from one part of a substance to another, while each part remains in its place.
Conduction takes place in solids.
Most metals are good conductors of heat.
Non-metals such as glass, wood, rubber, paper, plastic and asbestos are poor conductors of heat.
Solids do not all conduct heat equally well.
Interesting uses of poor conductors:
Handles of pans, irons, etc. are made of wood or plastic or other poor conductors. This keeps ones hand from getting burnt.
Clothes (wool, cotton), the furs of animals, feathers, are all poor conductors of heat.
A glass table top and table mats of wood, cork, cotton or plastic protect shiny wooden table tops from being marked by warm pots.
Cold meat and cold drink can be kept cold on a long journey by wrapping them in newspaper or a woollen blanket. Paper and wool are poor conductors.
Ice can be kept for a long time in sawdust or wrapped in a towel.
Houses with thatched roofs are warm on cold days and cool on hot days.
House with flat roofs are insulated with a layer of glass fibre above the ceiling.
Eskimos build houses of snow to protect themselves from the cold.
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child

child interact with other kids under doc supervision.
play therapy.
speech therapy.
Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game.
string and beads game.
the more you interact with the child the more effective

results you'll get..
please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
