Natural resources can be classified as renewable and nonrenewable resources. Natural resources can be classified as renewable or nonrenewable
A renewable resource can be replaced at the same rate in which the resource is used
Common renewable resources used to produce energy include,
Solar, like these solar panels converting solar energy into electricity. A nonrenewable resource is a resource that forms at a rate that is much slower than the rate that it is formed. Coal is an example. It takes millions of years to create coal and once it is used up it is no longer available
You can use CON to remember three popular nonrenewable resources.
This stands for
Coal
Oil
Natural Gas

I cover four types of friction. Static, fluid, kinetic, and rolling.
Static friction in which two surfaces are not moving past each other.
Sliding or Kinetic friction where 2 surfaces slide past one another.
Rolling friction between a rolling object and surface it rolls on.
Fluid friction is friction that occurs when objects move across or through a fluid.

You may have to wear glasses. How do they work? When you are farsighted ( hyperopia) objects far away are clear but object close appear blurry. This type of problem can be fixed with a convex lens. A concave lens is used to fix the opposite problem created when you are nearsighted.

As the moon rotates around the earth it travels through phases.
The alignment of the sun, earth, and moon create the phases.
I use an orrery to explain the moon's alignment during,
new moon, waxing crescent, ist quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent, and back to new moon.
The sidereal period is 27.3 and the moon is measured against stars.
The synodic period is 29.5 days and the moon is measured against the sun.

Layers of the Earth based on chemical composition and physical properties
Earth can be divided into three layers based on chemical composition: the crust, the mantle,
and the core.
Earth is also divided into layers based on physical
properties, such as whether the layer is solid or liquid.
The five physical layers are the lithosphere, asthenosphere,
mesosphere, outer core, and inner core.

A simple test to see if a number is prime or composite. All you do is find the square root of the number. Next, find all the prime numbers of this number. If none of these prime numbers are a factor of the number then the number is prime.

Kingdom Animalia Characteristics-Animal Kingdom
The kingdom Animalia comprises of most of the organisms we face daily. Your pet dog belongs to the kingdom, along with snakes, frogs, cats, and humans.
There is a huge variety of creatures in this kingdom, but animals have these common characteristics.
All animals are eukaryotes this means the have a nucleus and membrane-bound organelles.
All animals are multicellular
All are heterotrophs
No cell wall
Two major categories.
Vertebrates which have a backbone and invertebrates that do not.
Invertebrates don't have a backbone or spine.
They include your sponges, cnidarians,several types of worms, mollusks, arthropods, echinoderms starfish,sea cucumber,sea urchins
Most of the animals on the planet are invertebrates.
Vertebrates have a backbone. Examples include,
Lancelets,lampreys,various kinds fish,amphibians,reptiles,birds, and mammals.
Animals are found on every continent and also have adaptations that help them survive.

Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion.
In this video, I focus on three ways heat can be transferred,
Conduction, Convection, and Radiation.
Conduction involves direct contact between objects and usually occurs among solids.

Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source.

Radiation occurs without objects touching and occurs in space.
For example, the energy of the sun warms objects on Earth due to radiation.

I show several examples or demonstrations for each type of heat transfer.

Quantitative Data vs Qualitative Data

Additional Information on Qualitative vs Quantitative Data
https://moomoomath.com/qualita....tive-vs-quantitative

Data can be divided into two groups called quantitative and qualitative data
Quantitative data is numerical
Qualitative Data id descriptive data
Let’s look at examples of both
Examples of quantitative data would be
The number of pets, time of day, the temperature outside
Quantitative data can be graphed
If you count or measure, you are collecting quantitative data
There are two types of quantitative data, discrete and continuous
Discrete data is usually data you can count and continuous data is usually data you measure. I have a separate video on these two types of data.
Qualitative is descriptive or observations and uses words
For example, the color of a house, smell of a sock, texture of a shirt
Quantitative or Qualitative
Consider a cat
Quantitative Data would be the cat has 4 legs and weighs 10 pounds
Qualitative data would be the cat is yellow, and has soft fur
A bookshelf
Quantitative would be you have 50 books and is 150 centimeters tall.
Qualitative data would be it is multi-color and has a smooth texture
