Kids Are Born Scientists

Here is a list of questions that people frequently answer incorrectly. Learning and understanding the correct answers to these questions is an enjoyable process-you and your children might be amazed.

Where do trees get their mass from?
How long does it take for the Earth to orbit the Sun? 
Which falls faster, a medicine ball or a basketball?
Can your sense of touch be reliably used to determine which of two objects is colder?
Is the Earth closer to the Sun during January or July?
Is the Moon's gravitational pull on the Earth greater, equal or less than the Earth's gravitational pull on the Moon?
How old is the Earth?

Where do trees get their mass from is answered here- if you're lucky you will learn something new and be amazed by the answer.

Whenever possible you should allow your child to figure things out for themselves. You should avoid just giving them the answers.

Is the Moon's gravitational pull on the Earth greater, equal or less than the Earth's gravitational pull on the Moon? Newton's Third Law provides the answer-for every action, there is an equal and opposite reaction.
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

Thank you, Chris.

Very nice, Chris, thank you for sharing!

Thanks Skylark and Tamsyn.

Science can be difficult to teach to children because much of reality is counter intuitive.  I guess that we need to identify the misconceptions that our children hold before we can adequately teach these basic concepts. Misconceptions are barriers to understanding and interfere with subsequent learning. I am attempting to cover fundamental concepts with these videos. 
Here is an example of a common misconception-young children frequently hear their parents say that the sun is rising or setting, leading them to conclude that the sun orbits the earth. Children naturally form mental models of the world based on their observations. Rejecting these intuitive mental frameworks can be difficult for young children. As parents you will need to identity misconceptions and then help your child to reconstruct their conceptual frame work.

You might find this counter intuitive-

The Inverse Square Law is very easy to understand and is encountered in several areas of science. A child who is aware of this law will find it easier to understand Newton’s law of gravitational attraction.

Nice Thanks chris. Karma to you!
Scientific general knowledge and scientific spelling were the only areas school thought I could work on with my kiddo. We have started reading science books but I think some background knowledge will make the reading more enjoyable. So thank you!

[Chris1]

Hi Mandabplus3,

Glad that you have found these videos useful. Heat and temperature are also frequently misunderstood by children. If you take two identical glasses of water and added ice to one of the glasses, that glass will have the greater heat. This is because you have added material to that glass.

Heat and temperature are different things;
 •Temperature is related to how fast the atoms within a substance are moving.
 •Heat is a measure of how many atoms there are in a substance multiplied by how much energy each atom possesses.

Things can be at the same temperature and have different amounts of heat.

Hope that you enjoy these videos-

"State certification for teaching science might well include making sure that new teachers are aware of the common student misconceptions that they will encounter, as well as being proficient in the underlying science," American humorist-philosopher Will Rogers observed: It ain't what they don't know that gives them trouble, it's what they know that ain't so."

Harvard graduates explain the seasons. http://youtu.be/p0wk4qG2mIg

[Chris1]

The Harvard graduates were unable to answer the question about the seasons because of a misconception about how the Earth orbits the Sun.

Like all planets in our solar system, the Earth is in an elliptical orbit around our Sun. In the Earth's case, its orbit is nearly circular, so that the difference between Earth's farthest point from the Sun and its closest point is very small.

How old is the Earth?
