Knal (een liedje over het ontstaan van de sterren en planeten)

# data[].attributes.body
Gisteren heeft het een hele dag geregend en het is deze week nogal bewolkt. Dat komt omdat er veel vocht in de lucht zit en er een lagedrukgebied boven ons land hangt. Dit betekent dat de deeltjes waarvan lucht gemaakt is, minder hard drukken dan normaal. Dat komt omdat er minder deeltjes zijn en omdat het koud is waardoor die deeltjes minder snel bewegen.

Wolken ontstaan doordat kleine vochtdeeltjes druppeltjes gaan vormen. Dat doen ze meestal aan minuscule stofdeeltjes die in de lucht zweven.

Nu je dit allemaal weet, kun je je eigen wolk gaan maken!

Dit heb je nodig:

•   Een doorzichtige, schone frisdrankfles met een dop

•   Een lucifer

•   Water

•   Een volwassene

DIT MOET JE DOEN:

Stap 1:

Doe een beetje water in de fles, zodat het ongeveer een centimeter diep is. Draai de dop op de fles en schud even flink, zodat er overal druppels aan de zijwand zitten. Draai de dop weer van de fles.

Stap 2:

Vraag een volwassene om de lucifer aan te steken. Blaas de lucifer uit en vang de rook in de fles. De gedoofde lucifer mag ook in de fles. Draai snel de dop erop en zorg dat de fles goed is afgesloten!

Stap 3:

Knijp zo hard je kunt in de fles. Laat hem ineens los om een wolk te maken!

(Je kunt ook een fietspomp gebruiken om druk op te bouwen, dan krijg je ook een 'dikkere' wolk)

Zo werkt het:

Eerst verspreid je het water door de fles. Daardoor kan het water alvast een beetje verdampen. Daarna doe je rook in de fles, dat zijn de stofdeeltjes waar druppeltjes aan kunnen vormen. Als je dan in de fles knijpt, gaat de luchtdruk omhoog en wordt de lucht een beetje warmer. Als je loslaat, daalt de druk ineens heel erg. Daarmee doe je hetzelfde als wat er in de natuur gebeurt en creëer je een echte wolk! Als je dan weer in de fles knijpt, gaat de wolk weg. Laat je los, dan komt 'ie weer terug, enzovoorts.

I have decided to change my Friday Favorite Pins to PINTERESTing! I have so many pins that I want to go through my own boards and repin topics. The Friday pins will be related to a topic. I will search my own boards. I am working on the Solar System and rediscovered many great pins.

Lucht is overal om ons heen. Je kunt het niet zien en toch drukt het op onze schouders. Hoe meet je dan zoiets? In deze les maken de leerlingen een barometer en houden de luchtdruk een paar dagen bij.

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!"
