This is a very nice presentation that I feel High School students would enjoy while they are learning the laws of gas. Many instructional forms were offered for the visual and kinesthesia learners with diagrams, pictures and equations.
The presentation started out with four buttons displayed that were easy to navigate. You may want to tell the students they need to explore in order from left to right since the last one (Amount of gas) is the only one that will take you on to the gas laws. This also happened on your second set of buttons - gas laws. I actually clicked Gay-Lussac's button first and could not get back to the gas laws until the caculation slide that gave me a choice to click back to gas laws or quiz. Very nice choice of colors and the organization of information and buttons.
