Spanish Mission System

As the Spanish empire spread over the southern portion of the present-day United States, the mission system was developed to facilitate colonial expansion and to pacify the Indians. Catholic priests and friars ventured into remote areas to build missions where they worked side-by-side with the Indians planting crops, hunting game, and preaching Christianity. The missionaries also taught the Indians about Spanish culture, including language, arts and crafts, and politics.

4th Piano Concerto in G Major, Op. 58 - Last Movement

Although Beethoven had performed his 4th Piano Concerto privately, in 1807, the public did not hear it until the 22nd of December, 1808. On that night they also heard four hours of new music in a cold concert hall (the heating system had failed to work properly).Â Â Â After he personally played this concerto at the December 1808 concert, Beethoven never publicly performed with an orchestra again.

In this clip, we see Murray Perahia playing the last movement of Beethoven's 4th Piano Concer

Charming Snakes- Cobras in the Dark

Cobras are one of the most poisonous snakes in the world. Their most

distinctive feature is their hooded head which they raise to intimidate

prey as it spreading their hood makes them look larger.

Cobras usually eat rodents, eggs, and frogs; but they also eat other

snakes such as rat snakes. Their venom is a neurotoxin and when injected

into prey, it paralyses the animal by shutting down the function of the

nervous system, which ultimately leads to cardiac

1 of 5_The Universe-Jupiter

A quote from the documentary: "Four hundred million miles from Earth exists a mini solar system of over 60 moons rotating around a powerful planet of gas. Its glowing colors and spots hold strange beauty, but contain violent storms and jet streams. Could one of its moons harbor life beneath its icy crust? Does our own planet owe its survival to this massive comic magnet?" This documentary is suitable for older elementary, middle school, and high school students.

How to Determine If a Graph Represents a Dilation

Students learn that when the dimensions of a figure are

increased or decreased to create a new figure that is similar to the

original figure, the transformation is called a dilation. Students are

then asked to determine whether a given transformation on a coordinate system represents a dilation. Students are also asked to graph a dilation of a given figure on a coordinate system by multiplying all of the coordinates of the vertices of the figure by a given number. E

Lead Poisoning

Once absorbed into our bodies, lead can have devastating effects on the brain and central nervous system. Learn more about lead poisoning in this short video.Â 1:32 min.

Separation of National and State Governments

The United States federal system divides power between national and state governments, both of which govern the same constituents. The powers granted to the national government in the Constitution are called delegated powers. There are three types of delegated powers: enumerated powers, implied powers, and inherent powers. (Video is narrated with slides and speeches.)

The Metric System

Learn about the relationships between units in the metric system and

how to represent quantities using different units. Estimate and measure

quantities of length, mass, and capacity, and solve measurement

problems.

What Is a Number System?

Understand the nature of the real number system, the elements and

operations that make up the system, and some of the rules that govern the operations. Examine a finite number system that follows some (but not all) of the same rules, and then compare this system to the real number system. Use a number line to classify the numbers we use, and examine how the numbers and operations relate to one another.

Number Sets, Infinity, and Zero

Continue examining the number line and the relationships among sets of numbers that make up the real number system. Explore which operations and properties hold true for each of the sets. Consider the magnitude of these infinite sets and discover that infinity comes in more than one size. Examine place value and the significance of zero in a place value system.

Place-Value Centers

First-graders develop an understanding of the numeration system by

relating counting, grouping, and place-value concepts. Activities

include measuring with Unifix cubes and using base-ten blocks. NCTM

standards: number sense and numeration, measurement, connections.

Our Nearest Neighbor: The Moon
