Suggest You - Rising Raisins and Pop Bottle Fountains - A Science Inquiry Experience - Part 1
Unlike a few eons ago these days one lawyer does not handle all legal aspects. It’s the era of specialists and lawyers too have diversified to exclusively deal with some specific aspects of law.So, what you must do when the need for legal counsel arises is to hire a lawyer who is an expert on what you need. Lawyers must be hired based on their experience and qualifications and not on their age, good looks, charm, nice office,
At this point, the experiment can go in two ways. One is for the student to suggest other items that might sink and float like raisins. What are the characteristics of these items that allow the activity? (Lightweight, not really smooth, etc.) Objects may include pieces of broken spaghetti, macaroni, straws, penny, marble, etc. Students can categorize objects that move and those
Mukhtar Mai is a shy Pakistani woman with such extraordinary courage that she was named Glamour's Woman of the Year, one of Asia's Heros by Time, and last week was honored by the United Nations. Most importantly, her unprecedented action after being raped by a gang of men in her village to settle a score against her brother, has led to the transformation of the culture of justice and education for her entire village.In 2002, a
First, the "Rising Raisins" have been in print forever, usually just as a diversion or bed time sleep inducement. For this activity it will be used to enhance observation skills as well as a spring board for a discussion of density. Feel free to adapt the activity and questions to suit the age of your students.
Though soda will work for this activity, I always use seltzer water. Soda has a tendency to get sticky upon drying while seltzer water will just evaporate with no mess. No mess, that's for me.
You will need a sealed two liter bottle of seltzer, a tall clear container, raisins, other testable items.
Ask the student to inspect the sealed bottle. What is seen? (Clear liquid) Are there any bubbles? (No) Now, open the bottle and ask what is seen and possible reasons for the occurrence. (Lots of bubbling, foaming over. Also, sound is heard. This could be caused by a reduction in pressure once the bottle is opened.) Where did the bubbles usually form? (On the bottle's walls) I wonder if bubbles need someting on which to form?
Now, pour the seltzer water into the tall clear container. No doubt, more bubbles will form on the container's wall. Show a raisin and have the student predict what will happen when it is placed in the container.
When added, the raisin will sink to the bottom. There, bubbles will form in its nooks and crannies. This will cause the raisin to float to the surface where the bubbles will pop. The raisin will sink again and the process will continue until little gas is left in the seltzer water.

Did you know that around 72% of Americans cannot qualify to buy a home the traditional way? And this number is increasing by the month. So where are you in this 72%... or can you get a loan the traditional way.You know... go to the bank and apply for a loan and walk out with a loan.These 72% are missing one or all of these requirements:1) Large Down PaymentUnless it is your first house and it fits in the

The impending divorce of Mrs. Paul McCartney, Heather Mills, from her hubby has turned ugly. As everyone knows, she was locked out of a home they shared and had to wait several hours before being able to retrieve some things. You know a divorce is going to be ugly when the little things matter.As soon as they got married the snide remarks started. People questioned a woman marrying a man roughly 25 years her senior. They've qu

As with all things in life, the quality of the preparation affects the final outcome and this is certainly true when it comes to planning and preparing a presentation.I have experimented with a number of methods over the years but I do believe that the simplest are usually the best.The Collection: Over a period of time think all round the subject and note down on a large sheet of paper or indeed several sheets,

Nokia's N series mobile phones are known for their impeccable multimedia functions and high end connectivity tools. Though all of the previous N series models were masters in functionality, seldom any serious attention given to their style quotient. Things have suddenly started to change as the 'geeky' N series mobile phones are all set to change their common perception as bulky smartphones. Their latest member – the Nokia N76
At this point, the experiment can go in two ways. One is for the student to suggest other items that might sink and float like raisins. What are the characteristics of these items that allow the activity? (Lightweight, not really smooth, etc.) Objects may include pieces of broken spaghetti, macaroni, straws, penny, marble, etc. Students can categorize objects that move and those that don't, then create possible reasons for their activity or inactivity.
Older students may be engaged with a discussion of density once they understand it fundamentally. Why did the raisin float? (It had bubbles around it.) Why didn't the bubble surrounded penny float? (Too heavy) Is the raisin's mass more or less at the top? (Same - the mass of the raisin itself remains the same just as your mass remains the same if you are on the ground or jumping into the air.) Continue questioning and move to questions about density. If we were to find the mass of the raisin and the mass of the same volume of water, which would have more mass? (Raisin - it sinks in water). If we were to find the mass of the raisin and its bubbles and the same volume of water as the raisin and bubbles which would be greater? (Water - the raisin/bubbles float because they have less mass combined as the same volume of water). And so goes it... As an inquiry questioning device to check understanding of density, the "Rising Raisin" is a winner.
Next time, we'll take the bubble formation ideas and use them in creating the "Awesome Pop Bottle Fountain." Have fun!
