New satellite-derived images of vegetation confirm extremely dry conditions exist that are ripe for fires in the western United States, according to a data collaboration between NASA and the USDA Foreign Agricultural Service.
Wedding party arrangements, English/Dutch

Sea stars live in low tide areas and eat both plants and animals. On the underside of sea stars' arms are tube feet which use water and muscular forces to suction to rocks, move, and capture prey.
The Remarkable Cocklebur: Worldwide Hitchhiker and Nature's Velcro
This essay from Wayne's Word explores the hitchhiking method of seed dispersal, and how a closer look at one of these bur plants gave rise to an invention.
How Many Drops?
In this lesson and its associated activity, students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface tensions, more water can be piled on top of a penny than either of the other two liquids. However, this is not the main point of the activity. Instead, students are asked to come up with an explanation for their observations
Making Decisions: Packaging and the Environment
This activity has students redesign and justify the packaging currently used in some consumer products. Design criteria include reducing the amount of packaging material by 25%.
Floaters and Sinkers: Curricular Unit
This curricular unit introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine the densities of solid objects, including the method of water displacement to determine volumes of irregularly-shaped objects. By comparing densities of various solids to the density of water, and by considering the behavior of different solids when place
To learn how friction affects motion, students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a rubber band stretches. They experiment with a range of materials to determine which provides the least/most friction.

Monroe Doctrine. Despite a relatively easy presidency, Monroe created
much controversy during his time in the office including the beginnings of the slavery issue and battles with Spain about Florida. This is a good overview of this time and provides insight into the events that were to follow.
Clouds and Precipitation by StudyJams
Clouds are made of water vapor and dust. When the water gets too heavy, it falls back to the Earth. Clouds are named according to their shape, such as cumulous, or puffy, stratus, or blanketed, and cirrus, or high and cold. Learn more about the types of clouds with this slide show from StudyJams. Vibrant images are set to music with information written under each photo. A short, self-checking quiz is also included with this link.
The Assassination of JFK (3:37)
The course of events surrounding JFK's assassination shocked the nation and left more questions than answers. This is a good overview of the events that came after the assassination and the
The Properties of Matter - by StudyJams
Matter is anything that has mass and takes up space. That is why mass and volume are the properties of matter. There are many different kinds of matter: conductors, insulators, and magnets to name a few. Learn more about the properties of matter with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.
Gravity and Inertia - by StudyJams
Gravitational force is the constant force of attraction between the masses of two objects. The attraction between objects and the Earth is called gravity. Weight is caused by gravity: it is the measurement of gravity's force on an object's mass. Learn more about gravity and inertia with this cartoon animation from StudyJams. A short, self-checking quiz is also provided with this link.
Seasons - by StudyJams
The Earth has four seasons: summer, fall, winter, and spring, which are caused by the Earth's rotation around the sun and the way the Earth tilts on its axis. Seasons are not the same everywhere. They vary by climate and region. Learn more about the season with this slide show from StudyJams. Vibrant images are set to music while information is written under each photo. A short, self-checking quiz is also included with this link.

Brain: The Inside Story's "Your Changing Brain"
Your brain began forming before you were born, building the intricate network of neurons that help you survive in the world. Once developed, the basic structures for sensing, feeling, and thinking last a lifetime—yet your brain continues to change. The neural connections keep making adjustments with every experience and everything that you learn. The exhibition, Brain: The Inside Story, which is on view at the American Museum of Natural History from Saturday, November 20, until August 14, 201
