Surface tension

What is surface tension and how are we able to lower surface tension?

Good Job

I would like to say that I'm very proud of all of you that went to science fair yesterday. Mr. Jung filled me in last night and great job to everyone. On today's topic. Give me a little high light for your element and what are the properties ect... Have a great weekend everyone..

So how is everything going? How did science fair go? Just on update would be great!!

Article

Who is your Science Guy? Give a little preview of this guy and what he did.

Properties

How are compound, molecules, elements, and particles able to change from one state of matter to the next?

Dalton's Law

What is Dalton's Law of Partial Pressures and give an example of how you would be able to use this law?

Diffusion and effusion

What is diffusion and effusion and what law did they help to inspire?

Pressure

Your Idea

How are you sell stoichiometry to the class? Why is your idea the best?

Gases

Who was the man that develop the model for studying gases? What is the model, and what does it do?

Labs the past two days

Reflect on the labs that we have had in the past two days and how they have affected your comprehension of the material?

Question

When finding our limiting reactant why do we always convert grams into moles? Why are we not able to go from grams of a substance to grams of another substance?

Today's Lab

What was the reaction that occurred in today's lab? How does this experiment relate to observing a limiting reactant? What was your limiting reactant?

Steps

What are the steps for determining the percent yield if you are given the mass of the two reactants?

WHY

Why do we need to find the limiting and excess reactants and how do they differ from the actual and theoretical yields?

Air Bags

How do air bags work and how are they used to prevent car accidents?

Its Over

Looking back on last night what was something that you could have done differently which may have had a different outcome for your project. Also what was the coolest project that you saw which was not your own?
