Learn Percent Change with this Gummy Bear Lab

Calculate Percent Change Lab

Need a fun lab that you or your students can complete in order to teach % change?
Use the Gummy Bear Lab in order to practice calculating percent change. When Gummy Bears are soaked in water overnight the gummy bear expands due to diffusion. You can use this fact to teach percent change.
Use the formula New-old/old x 100 = % Change You can calculate the % change of the width, height, mass, and even density. Here is a link to a good lab sheet Gummy Bear Lab Sheet ( Free)

Types of Galaxies in the Universe

Types of Galaxies

A galaxy is  huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Some scientists think there could be as many as one hundred billion galaxies in the universe.Galaxies have different shapes and are classified according to the Hubble classification.

There are four main classifications of galaxies

Elliptical which are featureless and spiracle.

Spiral galaxies have arms that spiral outward.

Lenticular galaxies are given the symbol S0. These galaxies consist of a bright central bulge, similar in appearance to an elliptical galaxy, surrounded by an extended, disk-like structure.

Irregular galaxies are any other galaxy.

Elliptical galaxies are classified with an E and are further classified as from E0 to E7.

E0 are the most spherical and E7 are the most elongated.

Spiral galaxies are also subdivided into two main types, regular which are classified with a S and barred spirals classified with a SB. A barred spiral galaxy has a bar shape in the center.

Our milky way galaxy is a barred shaped Galaxy.

The regular spiral galaxies are subdivided according to how tight the arms are, SA arms are tightly wrapped and SC have arms that are lose.

Barred galaxies are also subdivided, SBa have tightly woven arms SBc are lose arms.

Irregular galaxies and Lenticular Galaxies are not subdivided.

Irregular are grouped with an Irr and Lenticular Galaxies are classified with a SO.

7 Largest Moons of Saturn

Saturn has at least eighty two moons.Many of these moons look unusual and are very small.

Here is a list of the 7 largest moons of Saturn from smallest to largest.

Number 7 Mimas was discovered in 1789 by William Herschel using a forty foot telescope.  It  has a diameter 396 kilometers and is composed mostly of water ice with only a small amount of rock.
A distinctive feature of this moon is a giant impact crater 130 km across, named Herschel.
The walls of this impact crater are up to 5 km high.
 This moon along with several of the other Saturn moons has these weird crater chains.

Number 6 Enceladus is the sixth-largest moon of Saturn. It is about 500 kilometers in diameter
and is mostly covered by ice, making it one of the most reflective bodies of the Solar System.
Enceladus was discovered on August 28,1789, by William Herschel. A prominent feature are huge geysers of water on the south poles These geyser observations give evidence that this moon is geologically active

Number 5 Tethys was discovered in 1684. This moon has a diameter slightly larger than 1000 kilometers.Tethys has the lowest density of all the major moons in the Solar System, indicating that it is made of water ice with just a small amount of rock. This moon has a huge impact crater named Odysseus,that is about 400 km in diameter.

Number 4 Dione was discovered in 1684 has a diameter of about 1123 kilometers.

Number 3 Iapetus was discovered in 1671 and has a  diameter of 1470 kilometers. The low density of Iapetus indicates that it is mostly composed of ice, with only a small amount of rocky materials. One strange feature is that the leading hemisphere is dark and the trailing hemisphere is very bright.
Similar to the other Saturn moons it has large impact craters. A strange feature of Iapetus is the equatorial ridge that runs along the center.

Number 2 Rhea  has a diameter of 1527 kilometers and discovered 1672 it is made up of ¼ rock and ¾ water. In 2008, NASA announced that Rhea may have a ring system. This would mark the first discovery of rings around a moon

Number 1 Titan which has a  diameter of 5149 km It was  discovered in 1655. Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. It is the only moon known to have a dense atmosphere, and the only known body in space, other than Earth, where clear evidence of stable bodies of surface liquid the  liquid may be  methane.
