Topic: Measuring Density (A) Portfolio Work Lab
Problem/Question: Will the object float or sink in water due to its density?
Introduction/Background: Matter is anything that has mass and takes up space. Mass we learned is the amount of matter in an object. There are many objects around us every day, all containing a different amount of matter. Density describes how much matter is packed in an object. Something could be really dense like over stuffing a suitcase. Or it could be just one item in a suitcase and that suit case would be much less dense. The density of water equals 1g/ml. Remember 1g/ml = 1g/cm 3. Things more dense than water sink. Things less dense then water float. You cannot change objects density even if you cut them in half! Remember we can always solve for density by using the equation:
Density (g/cm3) = Mass(g)/ Volume(cm3)
Hypothesis:
Object Name / Float or Sink? / Reason!?Object 1
Object 2
DO NOT TOUCH ANY OF THE OBJECTS AT YOUR TABLE. Of the objects at your table make a hypothesis and predict which ones will float.
In the cups below place a large X where you think it would float.
OJBECT 1 OBJECT 2
Procedure:
- Make sure you have completed your hypothesis.
- Calculate the density of the 3 objects.
FIRST FIND THE MASS
- You must first find the mass using the triple beam balance.
- Make sure all the weights on the balance are to the left, and the arrow is on the zero.
- Place your object on the center of the pan, then move the weights (making sure they click in) to zero the balance again. Then add the weight to calculate the final mass.
- Copy your results into data table 1.

Procedure:
FIND THE VOLUME
- To find the volume you must multiply the length times width times height

Asunto: Densidad que mide (b) SPANISH Trabajo de la lista
Problema/pregunta: ¿ El objeto flotará o se hundirá en el agua debido a su densidad?
Introducción/antecedentes: Materia es cualquier cosa que tiene masa y toma el espacio. La masa que aprendimos es la cantidad de materia en un objeto. Hay muchos objetos alrededor de nosotros diarios, todo conteniendo una diversa cantidad de materia. La densidad describe cuánto materia se embala en un objeto. Algo podía ser realmente denso como el excedente que rellenaba una maleta. O podría ser apenas un artículo en una maleta y esa caja del juego sería mucho menos densa. La densidad del agua iguala 1g/ml. Recuerde 1g/ml el = 1g/cm 3. Cosas más densas que fregadero del agua. Las cosas menos denso entonces riegan el flotador. ¡Usted no puede cambiar densidad de los objetos aunque que usted los corta por la mitad! Recuerde que podemos solucionar siempre para la densidad usando la ecuación:
Densidad (g/cm3) = volumen del (G) de la masa (centímetro3)

Soggetto: Densità di misurazione (B) ITALIANLavoro della cartella
Problema/domanda: L'oggetto galleggerà o si affonderà in acqua dovuto la relativa densità?
Introduzione/priorità bassa: Materia è qualche cosa che abbia massa e prenda lo spazio. La massa che abbiamo imparato è la quantità di materia in un oggetto. Ci sono molti oggetti intorno noi giornalieri, interamente contenendo una quantità differente di materia. La densità descrive quanta materia è imballata in un oggetto. Qualcosa ha potuto essere realmente densa come l'eccedenza che farcisce un suitcase. O potrebbe essere appena un articolo in un suitcase e quella cassa del vestito sarebbe molto meno densa. La densità di acqua è uguale 1g/ml. Ricordi di 1g/ml = 1g/cm 3. Cose più dense del dispersore dell'acqua. Le cose meno denso allora innaffiano il galleggiante. Non potete cambiare la densità degli oggetti anche se li tagliate a metà! Ricordi di che possiamo risolvere sempre per densità usando l'equazione:
Densità (g/cm3) = massa)/volume (centimetro (di g3)
Ipotesi:
NONNE TOCCHI C'È NE DEGLI OGGETTI ALLA VOSTRA TABELLA. Degli oggetti alla vostra tabella faccia un'ipotesi e predica quali galleggeranno.
