Balloon Expansion

Balloon Expansion

Balloon Expansion

  1. Stretch the opening of the balloon around the open end of the bottle.
  2. Set the bottle on the hot plate.
  3. Give the bottle and balloon apparatus a few moments to get warm. This may take a while, but you won't want to take your eyes off of the balloon.
  4. Once the bottle is warm, what happens to the balloon? Wow! It's filling with air. But how?

How does it work?

So what made the balloon begin to fill with air? We could be wrong here, but we're pretty sure that there isn't a tiny person in there blowing as hard as he can. Instead, you are seeing the expansion of air. Unlike water, which expands when it is cooled, air expands when it is heated. Since the bottle was full of air when you stretched the balloon over it, it only had one place to go when it began expanding… into the balloon!

WHAT IS PROJECT ;;;;;;;;;;;;;;;;;;;

9th grade science fair projects

How to Present Yourself

Science fair projects require a decent level of presentation. You may be asked by your teacher to orally present your project in front of the whole class. Your presentation must be short yet complete. Explaining your project to your class may be the most difficult thing you will ever have to do. You off course would want to do a great job, so you will require a lot of practice.

Actors and speakers always record their acts or speeches on a tape or a video recorder and look at it or listen to it so as to evaluate their performances. You could probably do the same as science fair projects may require a similar effort. Seeing yourself present your project on video could be the biggest eye opener. Moreover, it could teach you tons of things you can improvise on.

Think about this: Your project is all ready and your display looks great too. Then the judge asks you a couple of questions, and you are dumbstruck because you are too nervous, or these questions never crossed your mind before. You wouldn’t want this to happen, would you? Yes, a well presented display speaks volumes about your project, but in the end it all depends on how you answer the questions and convince the judge that you know what you are doing, and that the work was done by you.

Invite your friends over for some snacks and encourage them to ask you any question that crosses their minds. Try to answer the questions in a scientific way. If you cannot answer the question, you must never exhibit ignorance or try to ‘wing it’ or guess it. Rather, honestly mention that you never came across the answer during your project research, and skillfully offer another piece of convincing information. The bottom line is that you must present yourself before the judges with confidence and zeal.

Your display gives the first impression about your science project, but your appearance gives the first impression about the person behind the project. A well dressed person naturally sends out positive vibes and enables you to introduce yourself and your project well. Your appearance may very well set the mood for the rest of the analysis.

What the Judges Are Looking For
All science fair projects have judging formats that are similar, but it will do you well if you are aware of the fact that judges start by giving each project average marks. The marks are subsequently added or subtracted from that point on.

You will be in a position to receive better points if you can:

1. Objectives of the Project
* Present unique ideas
* State the problem in an understandable way
* Pinpoint the variables and use controls
* Help the judges to relate to the problem
2. Project Skills
* Know your equipment
* Be acquainted with what has to be done to arrive at the stated result
* Conduct the experiment on your own
3. Collection of Data
* Maintain a full-fledged journal
* Finish the project within the stipulated time limit
* Repeat the experiment in order to verify the verify the end result
* Present results that can be easily measured
4. Interpretation of data
* Represent data in the form of tables, charts and graphs
* Interpret data by using research
* Collect sufficient information to reach a conclusion
* Make your conclusion purely based on the data collected
5. Presentation of science fair projects(oral, written, display)
* Create a report the is complete and includes all necessary facts
* Answer questions correctly
* Use the display to support your oral presentation
* Verify conclusions based on experimentation results
* Summarize all facts learned
* Present a display that reflects your originality and creativity
* Present an appealing display

Some dos and don’ts at Science Fairs:

* Always bring some reading material along since you never know how long the judge or judges will take to arrive.
* Introduce yourself to your fellow presenters. Be sociable and polite.
* Enquire about your fellow presenters’ projects. Brief them about your project if they would be interested.
* Have fun.
* Be silent and don’t distract or disturb your fellow presenters.
* Remember that you represent your school. So your attitude and actions will definitely affect the way they think about your school.

A great resource for science project ideas, as well as how to do them, is the science project blog. Definitely worth bookmarking.

Be sure to look for my other articles on science projects. Now go get going!

PROJECT TYAR KARTANA VIDYARTHYACHE SAMPURN DGANYAN APEKSHAIT AAHE

Today was the school science fair. I have had a very busy week (I really need to learn to skill of saying no!) and just didn't realise that it was on this afternoon. Fortunately one of my friends left a message for me on my mobile this morning.

I was the first parent to arrive so I got to see the whole class waiting behind their science projects.


They got to show us their volcanoes in action. It was an impressive show!



Mia was the team leader for this volcano. Suited her bossiness perfectly.




Then she read me a science experiment where she had planted a bean seed.


And then I raced down to Charlie's class for the last few minutes. Fortunately he wasn't too stressed about me being there or not. We did some of the same experiments that Mia did when she was in Primary. You can see that here.



PROJECT 2

THE SCIENCE FAIR IS HERE!!!


The SCIENCE FAIR is finally here! PARENTS can come view all of the Haywood Science Projects tonight 4/28 from 5:30 to 7:30. There will be FREE ICE CREAM!

Our class tested 4 different types of insulation. Check out these pictures of us working on the project....

Solar Energy Science Projects
What variables can be used in a science project about solar energy?

I am helping my daughter with her science fair project and she has decided to go with alternative energy. From that she decided she wanted to build a model solar home or car and show how using solar energy would help decrease pollution. Her science teacher has told her to make sure she uses more than one variable..Now we are lost..What variables can be used with this type of project? Any help will be greatly appreciated…

For solar I’d use:

# of hours each day of sun (only shine the light so long)
% of transmission of sun , simulating clouds (use filters)
Angle of the sun to the panels, this affects efficency, that’s why some are made to move, perpendicular is best
Timing of use of electricty on non critical use items that could be delayed until sunny (clothes washing, dishwasher…..)
Difference between using a battery storage system and not. Using a battery will enable use in non-sunny times and store excess electricty as well that might go unused without it
