SCIENCE EXPERIMENTS


Flying Papers.
Hold a regular sheet of
paper to your bottom lip (you may have to
play a bit to find the exact location) and
blow hard across the sheet. The sheet flies
up! This is the same reason airplanes can
fly. As you blow across the top of the sheet,
you lower the air pressure (because the air
is moving faster), and thus the pressure on
the underside of the sheet is now higher,
and higher air pressure pushes the sheet
upwards.


Kissing Balloons.
Blow up two balloons.
Attach a piece of sting to each balloon.
Have each hand hold one string so that the
balloons are at nose-level, 6" apart. Blow
hard between the balloons and watch them
move! The air pressure is lowered as you
blow between the balloons (think of the air
molecules as ping pong balls ... they balls
don't have enough time to touch the balloon
surface as they zoom by). The air
surrounding the balls that's not really
moving is now at a higher pressure, and
pushes the balloons together.

Egg in a bottle science experiment


The Egg in a Bottle experiment illustrates the effects of air pressure. Air pressure is manifested in different phenomena, so are its effects.
When it comes to weather, air pressure plays a big role too. Most of the changes in a particular place's weather are governed by air pressure.
In this experiment, you will learn more about air pressure and its behaviour by putting an egg into a bottle and taking it out again without destroying the

 Can you figure out why the egg gets sucked into the neck of the bottle?

What you need

  • 1 x hard boiled egg
  • 1 x glass bottle with a wide neck (just wide enough to sit the egg in)
  • Boiled water from the kettle
Pour boiling water into the bottle to about a third of the way up.
Place the hard boiled egg so that it sits in the neck of the bottle.

Watch and wait. You will notice the egg gets shifted by the hot air in the bottle, this is when the hot air expands and escapes a bit.
The egg will eventually get sucked into the bottle.

Why is it so?

The hot air from the hot water expands and forces its way out of the bottle, making the egg shift around.
As the air cools inside the bottle the air contracts and takes up less room. This creates lower pressure inside the bottle than outside. The greater pressure outside the bottle forces the egg into the bottle.

Hints and tips:

  • To get the egg back out of the bottle, tilt the bottle and blow air into it. Watch out though, because the egg will shoot out of the bottle!

NASA Climate Kids


NASA Logo Do a science fair project!

Test, answer, or show?

Your science fair project may do one of three things:
Cartoon line graph with two ascending lines.
  • Test an idea (or hypothesis.)
  • Answer a question.
  • Show how nature works.

Topic ideas:

These are just the beginning of ideas. Ask a parent, teacher, or other adult to help you research the topic and find out how to do a science fair project about it.
  • Measure the cloud cover in the sky.
  • Test the effect of a mild acid on sea shells. (Test lemon juice or vinegar, for example.)
  • Demonstrate how Earth's water cycle creates fresh drinking water from sea water.
  • Cartoon greenhouse with Earth inside.
  • Investigate the greenhouse effect outdoors, over one week using two thermometers, two shallow open boxes lined with soil, with one covered tightly with clear plastic wrap, and a notebook for taking temperature readings through the day and night. Or use a different, but well-controlled method of comparison.
  • Cartoon cloud with rain.
  • Make a do-it-yourself rain gauge. Measure the rainfall during one storm or over several days.
  • Make a cloud in a bottle.
  • Demonstrate why the equator is warmer than other parts of Earth (unequal heating of Earth's surface) using a flashlight, graph paper, a ruler, and masking tape.
  • Cartoon ice cube with melted water around it.
  • Compare the freezing point of fresh water with the freezing point of seawater or salt water, with varying amounts of salt.


By the way, what is science anyway?

MEDITERRANEAN DIET: IS FAST FOOD KILLING OFF SPAIN¨'S FAMED MEDITERRANEAN DIET?

https://elpais.com/elpais/2015/07/14/inenglish/1436884922_083159.html

The profusion of fast food restaurants in historical city centers along the Mediterranean – where the most popular menu item is often a dish of spaghetti swimming in a pool of industrially produced carbonara sauce – is just one of the signs that a slow but inexorable change is underway: the end of the Mediterranean diet.
This dietary change conceals a social transformation that goes far beyond food. The Mediterranean diet, once a way of life as much as a way of eating, has morphed into something that looks more like a medical recommendation than a reflection of social mores.
A June report by the United Nations Food and Agriculture Organization (FAO) and the International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM) notes that the region is shifting away from its traditional diet, and warns that the effects of this shift go beyond nutrition.
“The abandonment of traditional habits and the emergence of new lifestyles associated with socio-economic changes pose important threats to the preservation and transmission of the Mediterranean diet to future generations,” reads the report Mediterranean Food Consumption Patterns.
One of the white paper’s key messages is that “it is urgent to preserve the cultural heritage of the Mediterranean diet as an outstanding resource for sustainable development as it contributes to promoting local production and consumption, encouraging sustainable agriculture and safeguarding landscapes.”

A surge in ready-to-eat food

Stall owners at the Antón Martín food market, in downtown Madrid, have already noticed the transformation.
“People don’t cook as much as they used to, and you can tell that young people buy a lot of ready meals,” explains Lorenzo, who has spent the last 16 years working at a butcher’s stall. “We sell a lot more steaks than meat for stews.”
“The Mediterranean diet involves local fresh produce that is grown nearby, which is why it’s a bit more expensive and requires more time,” explains Lluìs Serra-Majem, a nutrition expert who teaches at Las Palmas University and one of the main sponsors behind the bid that got the Mediterranean diet inscribed as an Intangible Cultural Heritage of Humanity item by Unesco in 2013.
“It’s not just the crisis that’s influencing in the decline. The problem is also a lack of knowledge: you need to know how to cook fish and vegetables, or how to shop for fresh food... All of this is a very important part of the Mediterranean diet,” says Serra-Majem, who co-authored the FAO study.
The gradual disappearance of traditional recipes – visibly happening with pulses, for instance – consumers who increasingly buy their groceries at supermarkets rather than traditional markets, and the rise of convenience food in a world where nobody has the time to cook, all underscore the profound social transition underway.
“We are living through the globalization of food,” explains Emilio Martínez Muñoz, a professor of physiology at Granada University. “These days, we no longer live on local, seasonal produce, but buy our food off the shelves of large stores containing a lot of ready-to-eat products. With the crisis, people were busier eating than wondering about what they were eating, and we are losing a lot of our food culture.”

Fewer fresh products consumed in 2014

The trend is mostly cultural, making its effects difficult to capture statistically. Yet the Agriculture Ministry’s 2014 report Food Consumption shows a decline in all products associated with the Mediterranean diet.
The study, which closely analyzes Spaniards’ eating habits, says that “the volume of fresh products that were consumed fell more (-3.3%) than other food types (-1.7%) even though the former experienced bigger price drops than the average drop for all food types.”
Between 2013 and 2014, consumers bought 3.1% fewer potatoes and fresh vegetables, and 6% fewer tomatoes. In the case of pulses, perhaps the dietary element that is disappearing the fastest from people’s tables, the drop was 6.1%.
“We observed that fruits and vegetables are falling behind in Spanish diets, which are increasingly oriented towards meat and milk products,” reads the report.
Eating habits reflect a society at a specific historical moment. The pure Mediterranean diet, born in southern Europe after World War II, represents a society with few resources where people spent their time out in the field, with no access to supermarkets, eating what grew out of the earth and leaving its preparation in the hands of women, who were mostly homemakers.
“It is the historical expression of a specific time and economic situation,” says Sandro Dernini, an FAO advisor and coordinator of the Forum on Mediterranean Food Cultures. “What’s happening right now is not a decline, it’s a much more complex situation than that.”
“We are not living the way we lived in the postwar era, we are not a poor country and people have changed the way they eat,” adds F. Xavier Medina, director of the Unesco Chair of Food, Culture and Development at Universitat Oberta de Catalunya.
“The food industry is much bigger than it was a few decades ago. It’s a cultural transformation, it’s not a crisis but a change. And now we are in the process of analyzing where our nutrition is headed,” adds Medina, who also contributed to the FAO report.

A generational change

Ramon Estruch, a doctor who chairs the Scientific Committee of the Mediterranean Diet Foundation, brings up another piece of research that confirms the trend.
“In the PREDIMED study [Prevention through a Mediterranean Diet], which included 7,447 subjects living in eight different regions, the degree of adherence to the traditional Mediterranean diet, on a scale of 14 points, was around 8.5,” he says. “Middle-aged and older Spaniards got a C+ or a B-, depending on how you look at it. But younger people scored much lower. In other words, we are losing the Mediterranean diet and are not even aware of it.”

With the crisis, people were busier eating than wondering about what they were eating, and we are losing a lot of food culture”
Emilio Martínez Muñoz, Granada University

“The key to this diet is the fact that it’s healthy food in a sustainable environment,” explains Ángel Gil, a professor at Granada University and president of the Ibero-American Nutrition Foundation. Above all, this diet is not just based on food but also on exercise.
“For many centuries, our species was not sedentary. We used to walk from one place to the next. But there’s been an enormous change: we’ve become sedentary, and that greatly reduces our energy consumption,” he continues.
Manuel Martínez, technical director at the European Institute of the Mediterranean Diet, which answers to the Andalusian government, admits there is “a growing shift away from Mediterranean diet-oriented consumer habits, and that in turn seems to be linked to a growing incidence of overweight individuals.”
“In a very broad study we are conducting on nutrition in Andalusia, we are not just analyzing how much people stick to the Mediterranean diet, but everything else that it represents as well, from the change in family structures to what children are eating, considering that the latter don’t take care to eat right unless their parents are on top of them,” he continues. “We have a lot of work ahead of us. We have to launch initiatives to encourage this diet and the consumption of local produce, but we also need to foment physical activity, which is included in the Mediterranean lifestyle. Without one of its parts, the whole does not work.”

Planets

http://beakersandbumblebees.blogspot.com.es/2010/01/toilet-paper.html?m=1
Yes! Today we used toilet paper to learn about science! How fun is that? To better understand how far from the sun each planet is we made a model. Remember kids...I am not Ms. Frizzle and can't turn our school bus in to a rocket ship and take you to the moon, therefore we have to make a model. The solar system is way to big to "see" so we have to model it! Toilet paper came in handy today for our solar system model!
The students were put into groups today and assigned two different planets. They were provided with a chart telling them how many sheets of toilet paper each planet is away from the sun. Mercury, the closest planet to the sun, was 3 sheets of toilet paper from the sun. Neptune, the farthest planet from the sun, was 224 sheets of toilet paper from the sun. The kids did quite a bit of counting today!
I was very proud of the teamwork efforts. The students seem to take every assignment seriously in Science! Even if it does involve toilet paper!
After this activity, we went back to the classroom and made bar graphs in the science notebooks!

Solar System tips-
Students need to know the following:
The Earth Rotates as it revolves around the sun
One rotation of the Earth is one day...24 hours
one revolution is a year.
the Earth revolving around the sun is also called an orbit...
gravity holds all the planets in orbit
My Very Excellent Mother Just Served Us Nachos...is a good way to help remember the order of the planets...Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
the sun is a star made up of gases

Today was "out of this world!"
