Warm ups 1

#1 – 8/7/15  The _____________ is the part of the scientific method where scientists make an educated guess, and they do an ______________ to test it.  Hypothesis, experiment

#2 – 8/10/15  ______________ is the amount of matter (stuff) an object is made of and ______________ is the amount of space it takes up.  Mass, volume

#3 – 8/11/15  What is the best unit for measuring the density of a solid object?  g/cm 3

#4 – 8/12/15  Which is more dense, 30 mL of water or 300 mL of water?  They have the SAME DENSITY ! 1g/mL  Explanation: 1 mL of water has a mass of 1 gram. If you increase the amount to 30mL then the mass will increase to 30g.

#5 – 8/13/15  What is the density of a box that is 10cm by 4cm by 5cm and has a mass of 400g? Will it sink or float?  10 x 4 x 5 = 200 cm 3  400 g / 200 cm 3 = 2 g/cm 3  It will sink because its density is greater than the density of water (1g/cm 3 )

#6 – 8/14/15  Draw a picture of 2 different boxes with the same volume but different densities.

#7 – 8/17/15  Write a sentence using these words: mineral, elements. Use page 66 for help.

#8 – 8/18/2015  Explain why coal is NOT a mineral.

#9 – 8/27/15  Explain the difference between the texture and composition of a rock. Use pages for help.

#10 – 8/28/15  Jose and Lilah notice that the granite sample that have is 40% feldspar, 35% quartz, 20% mica, and 5% hornblende. Which property of the rock is this?

#11 – 8/31/15  What do scientists call an extrusive igneous rock that cools so fast that gas bubbles were trapped inside and left holes in the rock?  vesicular

#12 – 9/1/15  Sedimentary rocks are made from fragments of __________, __________, and _________ rocks because rocks are constantly recycled.
