Please use only one font style in a slide.Though this is nice, it is not appropriate for a scientific presentation.

Watch out for portions of the text that have poor contrast with your background. All it takes is a little layout adjustment. Please see suggested changes in the next slide.

Please revise your outline so it flows smoothly. Discuss “Behavior” after “Mass.”

Introduction

• JUPITER is the fifth planet from the sun• Largest planet within the solar system• Considered as a Gas giant containing 90%

hydrogen and 10% helium

• Mass: one-thousand that of the sun but is two and a half times the mass of all the planets in our solar system

• Also classified to be a Jovian or also known as outer planet together with Saturn, Uranus, and Neptune

Too many words. Please remove unnecessary words. For example, the first bullet point can just be: “5th planet.”

Structure & internal structure

• Composed primarily of gaseous and liquid matter

• Considered as the largest planet----having a diameter of 142,984km at its equator

• Density: 1.326g/cm3• Outer layer is composed of molecular

hydrogen• Surrounding layer is composed of metallic

hydrogenhttp://4.bp.blogspot.com/-3EVjPHiDhgo/T25xOr8PZ0I/AAAAAAAAAK8/6e3Vl1A5u78/s1600/jupiter.jpg

Portions of the text are not contrasting with the background. For this, you may want to use a text box with a solid fill but with a transparency reduced to 60%. (More comments in next slide)

Another problem with the slide is that the main picture (the cut-out diagram) is not emphasized. Please see suggested changes in the next slide.

What is the difference between your 4th and 5th bullet points? Outer layer versus surrounding layer? Please clarify this- it will confuse your audience.

Behavior

• The average distance between Jupiter and the sun is 778 million km

• The distance from Jupiter and the sun varies by 75 million km between perihelion and aphelion

• Completes an orbit every 11.86 years• Jupiter’s elliptical orbit is inclined 1.31

degrees compared to earth• Does not experience seasonal

changes:small axial tilt (3.13)• Fastest of all the planets, completing its

axis in less than 10 hours

Another way of increasing contrast between text and background is to apply “outlines.” See the difference between this slide and the next.

Again the inset picture (smaller one) clashes or competes for attention with the background. When showing other pictures, it is better to use a plain background.

Composition

• Jupiter’s atmosphere is composed of about 88-92%hydrogen and 8-12%helium by percent volume or fraction of gas molecules

• The atmosphere contains trace amounts of methane, water vapor, ammonia, and silicon based compounds

• There are also some traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine, and sulfur

• Through infrared and UV measurements, trace amounts of benzene and other hydrocarbons have been found

• The outermost layer of the atmosphere contains crystals or also called frozen ammonia

The inset picture has been scaled wrongly. Perhaps you stretched the side nodes instead of the corner ones? Also, there is too much text in this slide.

Another problem with the slide is that you went back to composition (structure) when you were already discussing behavior. This gives the presentation a disorderly feel because you jump back and forth from topic to topic instead of following a smooth outline.

The layout needs to be improved. Also, be careful of chemical formulas- watch out for proper subscripts and superscripts.

Mass

http://www.naturalnavigator.com/wp-content/uploads/2010/09/Moon-Jupiter-cloud-and-trees.jpg

Moons of Jupiter

• Was discovered by the great scientist Galileo Galilei and Simon Marius

• Lo, callisto, ganymede,and europa are the four moons of jupiter

• for every four orbits that Io makes around Jupiter, Europa makes exactly two orbits and Ganymede makes exactly one

• This resonance causes the gravitational effects of the three large moons to distort their orbits into elliptical shapes, since each moon receives an extra tug from its neighbors at the same point in every orbit it makes.

This font style is too fancy for a technical presentation. There are too many words in this slide.
