Week 23 Science DCA Review

1. At what temperature (in Celsius) does water boil?

100° Celsius

2. Can you predict the amount of rain expected over the next month by using a weather map?

NO!Maps can give the direction of fronts, the direction of wind, temperature and pressure, but it can NOT predict rainfall for a month!

3. What causes high tide and low tide?

The pull of the moon on Earth

NOTThe pull of the Earth on the moon.

4. Which day of the week will it most likely snow and why?

Day Temp. Clouds Wind

Monday 23 Clear None

Tuesday 8 Cloudy 15 mph

What is the daily rise and fall of the ocean

called?

5. What most likely caused the difference in growth between Plant A and Plant B?

Plant A(Window)

Plant B(Closet)

Week 1 4 cm 4 cm

Week 2 8 cm 4 ½ cm

Week 3 10 cm 5 cm

Plant A grew more because it received more sunlight since it was in a window.

6. If 2 students have a terrarium and one puts a cover on it and the other doesn’t, why is the terrarium with no cover always needing water and drying out?

EVAPORATION

Without the lid, the water evaporates.

During EVAPORATION

What happens when aWarm air mass meets a

cold air mass?

Stormy Weather

Name each step in the water cycle.

1.Sun = Energy Source
