Behavior

May 8, 2018

Question

Explain what stimulus stimulates motivated behaviour.

Nichole - UK (28546)

Answer

A stimulus is any object or event that elicits a sensory or behavioral response in an organism.

Motivated behavior is the influence of an individual's needs and desires both have a strong impact on the direction of their behavior. Motivation is based on your emotions and achievement-related goals. There are different forms of motivation including extrinsic, intrinsic, physiological, and achievement motivation.

Question

Hi!

My name is Eva and I am a high school tutor. I have recently started helping out at the elementary and middle schools as well. A few of the younger students have been looking for help with their science projects. While science is definitely not my strongest subject, pretty much any info is accessible on the Internet! During my web searching, I came upon your web page: https://school-for-champions.com/education/resources.htm . Your page had a lot of super helpful and interesting sites.

I am writing this email to thank you for the great stuff. This is a little random but I also wanted to let you know about this article, https://www.certstaff.com/classes/astronomy-computer-games-kids.html that had a ton of great astronomy games for kids. One of my students did his project on the solar system and I found this page while I was looking for resources for him to use. I found this particular article very interesting and a fun resource for anyone learning about space. I know my kids really liked it! I'm not sure if you're updating your page but i think this would fit right in! Either way, I wanted to thank you and tell you to keep up the good work! I hope you have a great day.

Thanks again,

Eva - USA (28545)

Answer

I'm glad the material was useful to you. I added inks to your suggested resource in the Education Resources and Science Project Resources pages.

I also have other information on Science Projects. Check it out.

Best wishes for success in your work as a tutor.

Product of Two Negative Numbers

Algebra

May 5, 2018

Question

why we take x= ab+(-a)(b)+(-a)(-b)=ab
because (-a)(-b)is already a question to proof

MANISH - India (28544)

Answer

(-a)(b) = -ab
(-a)(-b) = +ab
ab + (-ab) = 0
Thus ab+(-a)(b)+(-a)(-b)= ab

Alcohol detox and sleep resource

Thanks

April 27, 2018

Question

Hi,

I wanted to send you a quick message because I love the work you’re doing on your site for Ron Kurtus' School for Champions and it goes hand in hand with some of our current projects. We’re trying to promote awareness of sleep disorders in high-risk populations. My team has been researching the reported rates of sleep disorders in alcoholics in active addiction and recovery, and we’ve found that many alcoholics are not prepared for dealing with insomnia during and after detox.

You can read our findings here: https://www.mattressreviews.net/alcohol-detox-sleep/

We'd love your support raising awareness of sleep health. Would you help us share this important information by adding a link to your Mental Health Resources guide.

Thanks so much for your time and consideration.

All the best,

Lucy - USA (28539)

Answer

Thanks for the resource. I added it to Mental Health Resources.

Best wishes for success in your work.

Is an atom electrically neutral?

Physics

April 26, 2018

Question

An atom is said to be electrically neutral?

melody - Nigeria (28538)

Answer

It is true that an atom is electrically neutral, because it has the same number of positive (+) and negative (-) particles.

See Structure of the Atom for more information.

Using symbols

Gravity

April 23, 2018

Question

I would like to request that you use NO SYMBOLS without a legend specifying the meaning of them. One would think that all materials would use the same symbols - they don't; moreover, many of us may not have seen a physics book in 40 to 50 years. It makes it very difficult when one doesn't know what the symbols mean.

Thank you.

Mike - USA (28536)

Answer

I am surprised that has been a problem with symbols. Equations in every lesson have a legend defining the symbols. For example:

v = gt

where

-- v is the vertical velocity of the object in meters/second (m/s) or feet/second (ft/s)
-- g is the acceleration due to gravity (9.8 m/s^2 or 32 ft/s^2)
-- t is the time in seconds (s) that the object has fallen

The only pages without legends for symbols are the Overview lessons that list a number of equations. And they have links to pages with details on the formulas.

Which is better pulley to use?

Machines

April 20, 2018

Question

Dear Ron,

I was reading a lot about the 3 classes levers, and must say that the explanation in your website was the most clear and easy to understand - thank you for this! (the example also really helped).

I have question regard the efficiency of a machine which utilize class 1 lever vs. machine which utilize class 3 lever. which one is better?

For example:
Case 1 (class 1 lever):
I have a long board, where a fulcrum is located in the middle in away that it divides the board into 2 parts of even length on both sides (in other words: a seesaw). Effort arm length = load arm length.
There is a load = X, and Effort= Y.
In such case, I push with effort X on one side, and the load Y will go up on the other side.

Case 2 (class 3 lever):
I have long board based on a fulcrum with a bearing on one side, and I pull the load up (maybe with a small cable in the end)
There is a load = X, and Effort= Y.
Effort arm length = load arm length.

In which case it will be easier to lift the load X up, assuming I would like to reach the same height in both cases?

Thank you!

Al - USA (28532)

Answer

I'm glad the material was useful to you.

Machine efficiency concerns losses due to friction, heat, etc. In the case of a lever, there is very little friction, so its efficiency should be 100%.

Usually, it is easier to push down on a lever, because you can use gravity to help you. However, pulling up on the load with a cable or even using a pulley could work better for you.

I hope that helps.

Experiments in static electricity

Static Electricity

April 19, 2018

Question

Hi! Thanks for your great page. I am working with two 5th graders on a science fair project on static electricity. They have built an electroscope and are hoping to determine differences in the charge imparted from different pets to a balloon. I'm trying to help them establish a hypothesis. First we have to determine if their device is even sensitive enough to determine differences in different materials, but assuming it is, knowing the reason for the differing effect of rabbit and cat fur may help them come up with a hypothesis. Some theories we have come up with are: density of fur leads to a greater surface area, i.e. More hairs per square inch= more electrons to lose; PH, i.e. Could different diets, etc cause one animal's fur to have a higher PH and therefore be less static-y? Finally, texture: this probably goes along with surface area, but maybe softer or courser fur plays a role?
Thanks so much!
Jenn

Jennifer - USA (28530)

Answer

That sounds like a good project.

Check out information in Static Electricity Experiments and Causing a Balloon to Stick to Things.

An electroscope can detect static electrical charges, but it probably is not good to compare small differences. The leaves will separate, but can you compare how much? But it is worth trying.

In Electrical Attraction of a Comb, there is mention of the differences in different types of hair.

I hope these ideas help, and best withes for success in your group's experiments.

Confusion on centrifugal force

Physics

April 17, 2018

Question

Summary
A centrifugal force is the outward inertial force on an object moving along a curved path. An object will move in a curved path provided some force is preventing it from moving in a straight line, which is the centripetal force.

The above is incorrect. An object moving along a curved path "EXERTS" a centrifugal force, it is not subject to such a force. An object moves along a curved path because it is subject to a centripetal force, if it was also subject to a centrifugal force, which is what you are saying, these two forces would cancel each other out.

Frank - UK (28523)

Answer

Thanks for your comments. I updated the summary of Centrifugal Force to try to clarify things.

A centrifugal force is the outward inertial force on an object moving along a curved path. An object will move in a curved path provided some force is preventing it from moving in a straight line, which is the centripetal force.

Since for every force, there is an opposite and equal force, the opposite of the centripetal force is the centrifugal force.

Finding the density of an object

Physics

April 15, 2018

Question

1. An object with the volume of 150 cubic centimetre has a percentage of volume submerged of 60% when immerse into water. What is the density of the object?

Request!!!!!!
can I get books of supplement material which have enough questions on densities, relative densities etc

Denis - Tanzania (28520)

Answer

If 60% is submerged in the water, that means that the volume of water displaced is 150 * 0.6 = 90 cc. Since the density of water is 1, the mass of 90 cc of water is 90 g.

Thus, the mass of the object is the mass of the displace water 90 g divided by 0.6 equals 150 g.

The density of the object is its mass divided by its volume or 150/90 = 1.67.

That seems to be a round-about way, but I hope it explains the subject.
Also refer to: Density of Matter and Factors Affecting Density of Matter.

Best wishes for success in your studies.

Best way to instill good character

Character

April 14, 2018

Question

Hi Mr Ron,Stumbled on this website while searching for good character traits.My question is there are many good characters available.What's the best way to instill a particular character?And what's the best way to do it so that it is ingrained into one's personality.Is self discipline considered a good character?Thanks Mr Ron Kurtus.Looking forward to your reply.

Ivan - Malaysia (28518)

Answer

Sorry for the delay in answering you.

Character can be divided into three classes. Personal character is related to your attitudes toward doing tasks, like how hard you work and doing a good job. Social character relates to your attitudes toward other people and their property. Honesty and kindness are good social traits. Group-based traits relate to following the rules of your group or society.

Self-discipline is a positive personal character trait. It allows you to finish what you start and to avoid negative activities.

Realizing the benefits you can get from having good character helps to ingrain it in your attitudes. Acknowledging a good deed or good job helps to reinforce that trait.

I hope that helps. Best wishes for success in having good character.
