Test Review


Physical Properties Test Review

1)      When would a science student need to wear safety goggles?  At all times in the lab

2)      Elizabeth was heating a beaker of water on a hot plate. What pieces of safety equipment should she be using? Safety goggles, gloves, apron,

3)      What state of matter takes the shape of its container? liquid

4)      John is building a simple electrical circuit that can be used for light energy. What materials will John need? A metal conductor, battery, light bulb

5)      A circuit is constructed using a 6-volt battery, copper wires, and a bell. Another circuit is constructed using a 9-volt battery, string, and a bell. The first circuit produced a sound. Why did the other circuit not produce a sound? The second one did not have a conductor to allow the electrical energy to pass through it.


6)      Draw a complete and working electrical circuit.

7)      A magnet has been dipped into each substance. Which substance is most likely coffee?

 The coffee is the magnet that has nothing on it

8)      How would you separate a mixture of iron fillings and pepper? By using a magnet

9)      Where would you place a thermometer when measuring the temperature of a solution? Inside the solution

10)  A student plans to boil water in an experiment. The student gets all the needed safety equipment from the teacher.  Lists all the tools the student needs to measure the boiling point of water? Thermometer

11)  What is likely to happen when a pot of water begins to boil on a stove top? The water begins to heat up and bubbles begin to form filled with the gas form of water.  Steam then rises out of the pot of water showing the transformation of water as a liquid into water as a gas.

12)  What is the freezing point of water in Celsius? degrees

13)  When using a thermometer do we use the Celsius or Fahrenheit? Celsius

14)  If a ball is floating in a cup of water does it have a higher or lower density than the water? It has a lower density than the water because it is floating.

15)  A piece of copper is placed on a hot plate for one minute. When the copper is picked up with tweezers, the copper is as hot as the hot plate. The copper is said be a ________. Conductor

16)  Which of the following are good electrical conductors (penny, rubber band, shoelace, or wooden toothpick)? Only the penny is because it is the only metal.

17)  A student examines a bar made of an unknown material. The material is shiny, hard, and feels cool to the touch. The student discovers that the bar conducts electricity. What is the bar most likely made of? Metal

18)  Why is a toaster's electrical cord covered in plastic? So it can insulate the electrical conductor inside of the wire allowing you to touch the cord without getting shocked.

19)  Do gas molecules have definite shapes or do they move around freely?  They move very freely

20)  List some examples of liquid turning into solids? Water to ice, liquid cement into solid cement

21)  Draw a model of how liquid molecules would look like in a container.

22)  Understand how this picture shows a solid, liquid and gas.  The solid is the ice cubes in the drink, the liquid is the actual fluid you would drink and the gas is the bubbles floating to the top of the cup.

At what point on the diagram does water change from a liquid into a gas?  
 

23)  What is typically happening when a solid is changing to a gas?  Is heat added to the solid or is heat removed from the solid?  Heat is typically being added to the solid

24)  Some girls are using a curling iron to fix their hair. It is very hot when plugged in for a while. If you wanted to protect your skin, what action should you choose when picking it up? You should pick up the plastic portion of the curling iron so you will be holding the insulated portion and not the conduction part.

25)  On question #22, do the upward arrows represent an upward increase in temperature or decrease in temperature?  Increase in temperature

4.     What is the adaptations cactus has made in order to survive its harsh conditions?  (Spikes, store water, waxy surface, adapted roots, etc)
5.     Define dominant allele. A dominant allele is an allele where its phenotype will always be represented when the allele for that gene is present.
6.     Define recessive allele. A recessive allele can be masked by a dominant allele when a dominant and recessive allele are present for the same gene.
7.     What is the difference between a dominant and recessive allele when crossed? The dominant trait will show up in the phenotype. Dominant allele in capitalized.
8.     What is heterozygous? One dominant allele and a recessive allele.
9.     What is homozygous?  Two of the same alleles.
10. What is a punnett square used for? To predict the probability of the traits of the offspring.
11. Complete an example of a punnett square when a male with brown eyes - BB is crossed with a female with blue eyes - bb. What is the ratio of the offspring?  100% Brown Eyes
12.  What is a genotype? Give an example. The combination of alleles Ex: Bb
13. What is a phenotype? Give an example.  The trait that will be expressed based on the 2 alleles – 1 from each parent. Ex: Purple Flowers
14. What would cause a species to survive changing environmental conditions and be able to pass their genes on to their offspring?  A species that could adapt to the new environment.
15. What are chromosomes? Cellular structures that are made of DNA that carry information that controls inherited characteristics.
16. Where is DNA located? Chromosomes in the nucleus
17. Who is known as the “father of genetics?” Gregor Mendel
18. How many genes do offspring receive for each trait? 2… One from each parent.
19. What happens when you get a fever? What temperatures would be considered a fever? You sweat.  Anything over the normal 98.6 would be a fever.
20. What is homeostasis? The process by which an organisms internal environment is kept stable during changes in its external environment?
21. What is a behavioral adaptation? Give an example.
Behavioral adaption is the things animals do to survive. Like bird calls or migrating are forms of adapting. When certain species are born they have to watch their parents or others surrounding them to understand what they have to do to survive. They have to learn to cope with the weather, enemies, and environment in a "suvival of the fittest" way.
22.What is a structural adaptation? Give an example.
Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear.
23. What kind of adaptations might an animal have in response to living in a dry, hot climate like the desert? It would avoid being active at night and conserve it’s energy for being active at night.
24. What kind of adaptations might an animal have to survive cold climates? Two layers of fur, inner layer insulates, outer layer sheds moisture and protects from wind
25. Why would an animal mimic the defense mechanism of a similar species? The other organism may be poisonous so by mimicking the defense mechanism of the other similar species it can evade predators.
26. How does homeostasis work with your circulatory system? It helps by increasing the blood flow in your body
27. Describe 4 different beak shapes birds have adapted to get nutrients from its environment.
a.     Crushing beak for hard seeds
b.      Crushing beak for plants, fruit buds, or leaves
c.      Probing beaks for insects in holes
d.     Stabbing beak for cactus parts and insects
28. What combination of genotypes would express a dominant trait? A recessive trait?
a.     Genotype express dominant trait – (any letter will work as long as both are capital or one letter is capital and the other is lowercase) BB or Bb
b.     Genotype express recessive trait – (any letter will work as long as both are lowercase) bb
29. Define asexual reproduction.
a.     Asexual reproduction – an exact copy of a single parent.
30. Define sexual reproduction.
a.     Sexual reproduction – causes genetic variation from the two parents.
31. What is the difference in the offspring of asexual and sexual reproduction?
a.     Asexual – offspring are an exact copy of parents.
b.     Sexual – a mixture of both parents.
32. What is the definition of selective breeding? What is an example?
a.     Selective breeding – the process of breeding plants and animals for particular traits; synonymous with artificial selection.
b.     Examples: different colored carrots, variegated ears of maize, charolais cattle produce more red meat and less fat, Chihuahuas and Great Danes are bred for size.
