Sponges and towels absorb water. TRUE or FALSE?
TRUE. They "soak up" water!
100
When water is dropped onto a penny, it becomes _______. A: absorbed OR B: a dome
B. Water domes on pennies.
100
The smaller the water drop, the faster it'll slide down a slope. TRUE or FALSE
FALSE. Big water drops move faster down a slope. Small water drops move slow down a slope.
100
When you find the mass of an object, you find how tall it is. TRUE or FALSE?
FALSE. The Mass is finding the weight of an object.
100
Most of Earth is covered in ________ water. A: Fresh Water (drinking) B: Salt Water (ocean)
B. Salt Water

Water beads on waxy surfaces. TRUE or FALSE?
TRUE. Water will bead up on waxy surfaces, like wax paper or a car.
200
Water Insects can "walk on water" because they don't break the water's surface tension. TRUE or FALSE?
TRUE. If they did break the surface tension, they wouldn't be "walking on water"!
200
What makes water run down a slope faster? A. How tall/steep it is OR B. How heavy it is
A. The taller the slope, the faster water will run down it!
200
1 g = 1 mL (grams are how the mass is measured and mL is how the volume is measured) TRUE or FALSE?
TRUE. 1 g = 1 mL (QUIZ: 4 g = ? mL, 56 mL = ? g)
200
Living Materials absorb water and dead materials tend to repel water. TRUE or FALSE?
FALSE. Living materials REPEL water & dead materials ABSORB water!
300
Rainboots do NOT have a waterproof surface. TRUE or FALSE?
FALSE. Rainboots DO have a waterproof surface. That's why we wear them when it's raining... so we don't get our feet wet. They REPEL water!
300
Definition of Surface Tension: surface tension is when water can be seen on top of something. TRUE or FALSE?
FALSE. Surface Tension is when water molecules stick together (like Red Rover) to create a strong surface.
300
What is the name of the force that makes water run down a slope? A: air/oxygen OR B: gravity
B. Gravity pushes everything down!
300
A Sponge can absorb _______ its own weight. A: 10 times B: 100 times
A. Sponges can absorb 10 times its own weight. When we did our experiment, our sponges weighed about 3g. They were able to absorb around 30g of water. 3x10=30 :)
300
Is water an Earth Material? A: YES or B: NO
A. Water IS an Earth Material. We can get it from the Earth. It is NOT man-made.

**DAILY DOUBLE** Miss Appleby has two cats. What are their names???
Pee-Wee and Kovu :)

In the Paper Clip experiment video, how was it able to float? A: the paper towel was pushed down around the edges, so it didn't break the surface tension of the water around the paper clip OR B: the paper clip floated on its own
A. The paper clip was too heavy to float on the surface, so the paper towel had to be gently pushed down so the surface tension didn't break around the paper clip!

You and your family are camping. You plan on fishing, so you want to camp near the water. It's supposed to rain at night. When it rains, the river floods at the bottom of the mountain. If you were to choose where to pitch your tent, would you want to be A: at the bottom of the mountain OR B: towards the top of the mountain.
B. Towards the top of the mountain will have the highest slope and it won't flood.
400
What is the MOST important thing to check before you start weighing objects? A: You have cups to hold items OR B: You zero your balance.
B. YOU MUST zero your balance before weighing items. Otherwise, you won't have the correct mass.

Water can be found underground and used to be filtered into water bottles. TRUE or FALSE?
TRUE. Remember Miss Appleby's drawing explanation?? :)
