WISE WORDS ABOUT LIFE-School Success

Need a little motivation in life?

Use these wise words for motivation in life and school. We all need words of encouragement and words to help motivate us. These short statements will help. 

If you don't have big dreams, big dreams can't come true. 

If you can complete these three habits consistently, Worry Less Exercise Daily Think Positive Life will move in a positive direction 

Don't just wander through Life Dream Big Make a Plan Set Goals Take Action. 

Miracle Equation, Unwavering Faith plus Extraordinary Effort 

Avoid Negative People 

Follow One Course Until Success 

If you don't ask you don't get. 

Your level of success is related to the questions you ask yourself.

Failure moves you forward 

Well done is better than well said, Ben Franklin. 

Making commitments builds hope, keeping commitments builds trust. 

I suggest you reread the list a couple of times or watch the video several times and settle on one or two statements that you can focus upon.

I have used " If you don't ask, you don't get as my yearly theme.

For example, if I don't ask my students to do great things then I probably won't get great work.

If I don't ask for a discount, then I probably won't get one.

If I don't ask myself to save money, I probably won't.

Physical Exercise for Brain Power

Learn why physical exercise is good for your brain.

What do experts say about exercise and the brain?

Wendy Suzuki Ph.D. author “ Healthy brain, happy life,”  says

“ exercise is the most transformational activity you can do for your brain.”

Dr. John J. Rate e ( Ratey) author of Spark: The Revolutionary New Science of Exercise says

“ The neurons in the brain connect to one another through “leaves” on treelike branches, and exercise causes those branches to grow and bloom new buds, thus enhancing brain function 

In addition, exercise increases your heart rate and allows your cardiovascular system to pump more oxygen to your brain. This added oxygen allows your brain to repair, regenerate, and function better.

Dr. John Ratey who has studied the impact of exercise has on learning for over a decade and has found that people who exercise before studying outperform people who do not.

Daily exercise that raises your heart rate of 20 or 30 minutes raises the level three important neurotransmitters.

Dopamine

Serotonin

Norepinephrine

Neurotransmitters are the molecules used by the nervous system to transmit messages between neurons, or neurons to muscles. Regular exercise can increase these three neurotransmitters.

In very simple terms dopamine impacts your level of motivation. Low levels of dopamine can result in low levels of motivation and high levels increase motivation.

Motivation is the key to learning new material.

Serotonin impacts your mood, anger, and depression. Low levels can lead to depression and higher levels can improve your mood which impacts your ability to learn

Norepinephrine impacts your ability to focus.

Low levels led to dull focus, and high levels sharpen your focus.

Twenty or thirty minutes of aerobic exercise has been described as a miracle growth for the brain.

So let’s apply this knowledge with a couple of suggestions to help you start brainstorming about how you can link exercise and learning.

Before your next study session gets your heart rate elevated for 20 or 30 minutes then start studying.

Take your flashcards on a brisk walk and memorize while walking

I do this all the time.

I go for an easy bike and as I ride I create the script to my next video in my mind. Ultramarathoner Dean Karnazas writes portions of his books while running and recording as he runs.

While studying take exercise breaks while you study. It could be as simple as dancing, or jumping jacks during the break.

Record your notes on your phone, put in your earbuds, go for a walk, and learn your notes.

The opportunities are endless, just combine 20 or 30 minutes of exercise with learning new material.

How to find the Protons Neutrons and Electrons of an element on the Periodic Table

How many protons, neutrons, and electrons does Boron have?

The periodic table provides a wealth of information for the elements. However, if you can't read the periodic table it is not very helpful.
Let's go over some basics found in each box of the periodic table.

You can easily fill out this chart if you know just a couple of facts.

Let's use Boron as an example.

The Atomic Number identifies the element and the number of protons.

Boron has 5 protons.

In order to find the electrons take the atomic number and subtract the charge. A neutral element will have a 0 charge. An ion will have a plus or minus charge.

The atomic mass is the average mass of isotopes of elements.

If you round this to the closest whole number if is the mass number which is a combination of protons and neutrons.

If you subtract the mass number minus the protons this will be an element's neutrons.

Boron would have 11 - 5 = 6 neutrons.

In the video, I work through each example. I find the protons, neutrons, and electrons for Silver, Potassium, Tin,  and Fluorine.

What are the different types of triangles?

A triangle is a three-sided plane figure with three sides and three angles.

The sum of the three angles always equals 180 degrees.

Up first are triangles that are classified by the length of their sides.

A Scalene triangle has three different side lengths. 

An isosceles triangle has two congruent or equal sides, and an Equilateral triangle has three congruent or equal sides.

Triangles can also be classified by their angles.

There are three angles often associated with triangles.

• Acute angles are less than 90 degrees

• Right angles are exactly 90 degrees

• Obtuse angles are greater than 90 degrees

All triangles have two acute angles and the third angle determines the type of

the triangle you have.

An acute triangle is a triangle with three angles that measure less than 90 degrees

An obtuse triangle is a triangle with one angle greater than 90 degrees.

A right triangle is a triangle with one right angle or ( 90 degrees).

Triangles are also classified by side length and angle measure.

This chart summarizes triangles classified by side length and angle measure.

A scalene triangle, remember it has three different side lengths can be acute…. right…. and an obtuse triangle.

An isosceles triangle, remember 2 equal sides, can also be acute…., right…., and obtuse triangle.

An equilateral triangle can only be acute because in order to have three sides that are equal the angle measure must be 60 degrees.

Mitochondria are found in?

Mitochondria are amazing and cool. They are found in plants... animals,....fungi,.....protists, and any other eukaryotic cell.

They can quickly change shape and move around the cell when needed.

When the cell needs more energy, the mitochondria can reproduce by growing larger and then dividing. For example, say you want to get in shape. As you exercise more the mitochondria in your muscles will increase in number and navigate to the edges of the cell, which allows these muscle cells to have more energy. If the cell needs less energy, some mitochondria will die or become inactive.

Mitochondria are very similar to some bacteria. For this reason, some scientists think that they originally were bacteria that were absorbed by more complex cells. This theory is called endosymbiosis.

 During cellular respiration with the help of oxygen, the mitochondria produce 25 ATP Compare this to only 3 ATP produced during glycolysis in the cytoplasm. Thus the title “ The powerhouse of the cell.”

So why is this a big deal?

In order to do something like running which requires a large amount of energy,

ATP is required, but how does this ATP help?

To carry out life processes, ATP is continuously broken down into ADP, like a rechargeable battery, and releases a huge amount of energy which is used by the cell in several metabolic processes as well as in building macromolecules such as proteins.

ATP is critical for the contraction of muscles. ATP supplies the energy to move the contractile muscle proteins.

ATP is essential for certain pumps like the sodium-potassium pumps and calcium pumps. The sodium-potassium pump ensures that our cells have the correct amount of sodium and potassium which is essential to stay alive

 The adenosine from ATP is a building block of RNA and is directly added to RNA molecules. During Transcription DNA is copied to mRNA, which carries the information needed to make proteins 

So next time you may do anything requiring energy like mountain biking,

You can thank the amazing and cool mitochondria, the powerhouse of the cell

Soil Horizons Explained

Soil  Profile and Horizons Explained

Soil is all around us Soil is essential. You walk on grass rooted in the soil and eat food grown in soil.
Plants and trees need soil to grow but
What is soil composed of

If you look at a chart of soil you will see that Soil is made up of,

45%  minerals
5%    organic matter like decaying plants and animals
25%  water
24%  air

You can also study soil by looking at the soil profile and the soil horizon
A vertical layer of soil that shows all of the different layers is the soil profile.
Much like your profile on Facebook tells others all about you The profile tells others all about the soil

A soil horizon is each individual layer of the profile. Each layer has different physical properties.

Learn the difference between soil profile and the soil horizons.

The soil horizons are the horizontal layers of the soil. The layers are o a e b c r. 

O horizon also called litter is composed of dead leaves, twigs, sticks, fallen trees The O horizon is thin in some soils, thick in others, and not present at all in others.

A horizon also called topsoil Contains rich organic matter along with some minerals. This layer contains decomposers. The decomposers perform the task of breaking down plants and animals. The remains of these plants and animals create a mixture called humus which is a dark, organic material that forms in soil when plant and animal matter decays.

E horizon also is known as the Eluviated layer as water moves down the soil substances are removed and pulled out in this layer resulting in a concentration of sand and silt particles composed of quartz or other resistant materials This layer may be missing in some soils.

B horizon Subsoil Lighter in color, many times reddish or brownish in color because it has less humus it is a zone of accumulation where materials like clay collects from the movement of water downward

C horizon Parent material this layer contains much of the material that the soil was originally made from. It will contain rock fragments. Weathering breaks down this parent rock into smaller and smaller pieces of rock This layer is most often light in color.

R bedrock  A mass of rock such as granite, basalt, quartzite, limestone, or sandstone that forms the parent material for some soils.

Landforms created by Erosion.

Erosion is the process by which sediment and other materials are moved from one place to another. There are four main agents of erosion, wind, water, ice, and waves.

Deposition is the geological process in which sediments, soil, and rocks are added to a landform or landmass.

Erosion and deposition have taken place throughout Earth’s history and have created a variety of landforms.

What landforms have been created by erosion?

Canyons and valleys pause

Canyons and valleys are created by the flow of water. As the water moves, it erodes rock and sediment from the streambed.

The steeper the river or stream the greater the erosion force. 

Erosion and deposition can form a flat area called a floodplain

When a stream empties into a body of water such as the ocean, an estuary, a lake, or reservoir. It’s current slows and sediment is deposited. A fan-shaped pattern is formed called a delta that can be created. 

An alluvial fan is created when the stream flows onto land. They are sometimes associated with flash floods. These fans typically form in mountain regions where there is a rapid change in slope from high to a gradual slope. When the land flattens out the flow of water loses energy and deposits sediment in a fan shape.

A meander is a bend in a river. The faster-moving water on the outside cuts into the bank. On the inside of the curve, water moves more slowly and deposits sediment. Sometimes a stream may cut a new channel that bypasses the meander. This cutoff meander may form a lake called an oxbow lake.

Groundwater can also be an agent of erosion

The groundwater dissolves and carries rock away and may create a cave.

If the roof of the cave collapses it may create a sinkhole.

The world's largest sinkhole. A sinkhole in Egypt is considered the largest in the world. It measures a staggering 80 kilometers long and 120 kilometers wide. Yes, that is kilometers not meters.
