Weather and the Water Cycle
1. List the three parts of the water cycle: evaporation, condensation, and
precipitation
2. What does it mean if there is a low barometer reading? What about a high
barometer reading? low barometer reading means cloudy and damp weather;
high barometer reading means dry and clear weather
3. What does an anemometer measure? What would a high anemometer reading
mean? measures windspeed; means windy weather or strong winds
4. How does a meteorologist make a weather forecast? by measuring temperature,
precipitation, air pressure, and wind over a large area
5. Mrs. Wilson used a can of root beer to make a root beer float. What should she do
with the can when she’s finished? take the can to be replaces
6. Name two ways people can help the environment. not littering, planting trees to
replace the ones that are cut down
7. What is a sea breeze? a wind that blows from water to land; this is caused
because the land heats faster than water.
8. True or False: When a tornado touches down, the safest place to be is in a shed.
9. Describe evaporation: the process of water becoming water vapor
10. True or False: During the day, land heats faster than water.
11. Los Angeles, California is near the Pacific Ocean and Chicago, Illinois is not near
any ocean. Why does Los Angeles have about the same temperature year round,
but Chicago has very cold winters, and hot summers? the distance of each city
from an ocean
12. Label the following instruments and then write what they measure:
Wind vane
measures wind
direction
Barometer
measures air
pressure
Anemometer
measures wind
speed
Thermometer
measures
temperature
13. Label the parts of the water cycle:
A: Evaporation
B: Condensation
C: Precipitation
Living Things
14. Explain the process of pollination and why it’s important for the reproduction of
plants. Pollination is the movement of pollen from stamen to pistil. The pollen must
be moved from the stamen to the pistil for fertilization to occur.
15. How do the following parts of a plant help during photosynthesis?



Stem: hold the leaves up to the sunlight and carry sugar to other plant parts
Roots: take in the water and nutrients needed to make food and stores
extra sugar and it anchors the plant to the ground
Leaves: absorb energy from the sunlight and take in carbon dioxide and
stores extra sugar
16. True or False: Flowering plants reproduce by creating and spreading pinecones.
17. A lion is a carnivore. Which animal would compete with a lion for food?
A. Gazelle
B. Giraffe
C. Cheetah
D. grass
18. Some plants, like ferns, do not produce flowers, so they reproduce using spores.
19. Cheetahs live in the African grasslands, and eat meat. Which of following
adaptations does not help a cheetah get its food?
A. soft fur
B. strong hind legs
C. Large teeth
D. sharp claws
20. Name an animal that changes in environment to improve its habitat: a beaver
building a dam
21. Explain how the following body parts help the body:


Heart: moves blood through the body
Lungs: take oxygen in from the environment
22. Food chains are driven by the power of the sunlight.
23. The food chain transfers energy in this order: sunlight  producers herbivores 
carnivores
24. Look at the picture below:
What would happen if the insects died
out? More mice would die.
25. What do the arrows in the food chain picture above represent? The flow of
energy
26. Madisyn saw an animal while camping with her family. The animal is a vertebrate,
lives on land, and is not a mammal. What could the animal that Madisyn saw be?
A. rabbit
B. trout
C. owl
D. fox
27. Some frogs are brightly colored to warn predators not to eat them. What warning
could their bright colors be? It’s bright colors warns predators that it could be
poisonous.
28. Many animals that live in hot climates are nocturnal. Why is this? They are
nocturnal because it is easier to keep their body temperatures cooler because it
is cooler at night.
29. Name two living things in a forest ecosystem:
1. trees
2. foxes
30. Name two nonliving things in a forest ecosystem:
1. soil
2. rocks
31. Fennec foxes live in the sandy Sahara Desert and other parts of North Africa. They
are cream colored with black tipped tails. They forage for plants but also eat
rodents, eggs, reptiles, and insects.
Name two adaptations that allow the fennec fox to survive in its habitat, and how those
adaptations help.
1. The fennec fox’s cream colored coat allows it to blend in with the sand making it
difficult to be seen by other animals.
2. The fennec fox’s feet allow it to dig holes to protect himself/hide and to keep
cool in the desert heat.
3. The fennec fox’s ears allow him to hear from far away to help him find food or be
aware of danger.
