assessment
what do you know now? (p. 10):
This preliminary assessment is an assessment tool designed to gain an
understanding of students’ preexisting knowledge. It can also be used as a
benchmark upon which to assess student progress based on the objectives
stated on the previous pages.
what have you learned? (p. 11):
This post assessment can be utilized as an assessment tool following
student completion of the program and student activities. The results of
this assessment can be compared against the results of the preliminary
assessment to assess student progress.
video review (p. 12):
The video review can be used as an assessment tool or as a student activity.
There are two sections. The first part contains questions displayed during
the program. The second part consists of a five-question video quiz to be
answered at the end of the video.

investigando la herencia
Before showing the video to students ask them to write down the color of their
hair on a piece of scrap paper. Next, ask them to write down their approximate
height. And last, ask them to write down their eye color. Ask them if they have
any choice of these features. Ask them if they were born with these features or
did they do something to get these features. Explain that these are examples of
inherited characteristics.
Next, ask your students to write down something they are good at or enjoy
doing. Answers may range from playing a sport, to reading, to playing a
musical instrument. Ask them if they inherited these abilities or if they learned
to do them. Write “acquired characteristics” on the board. Explain the acquired
characteristics are things we learn how to do. We are not born with acquired
characteristics. Tell students to pay close attention to the video to learn more
about inherited characteristics, acquired characteristics, and heredity.
program viewing suggestions
The student master “video review” is provided (p. 12) for distribution to students.
You may choose to have your students complete this master while viewing the
program or do so upon its conclusion.
The program is approximately 10 to 12 minutes in length and includes a fivequestion video quiz. Answers are not provided to the video quiz in the video, but
are included in this guide on page 9. You may choose to grade student quizzes
as an assessment tool or to review the answers in class.

heredity and traits
02  Have
you ever wondered why some animals look nearly identical to their
parents?
03  For example, notice how this lamb looks a lot like its mother.
04  In many cases the same holds true with plants.
05  Young plants often look very similar to their parents.
06  You may have also noticed that some children look very much like their
parents.
07  What causes this?
08  The answer lies in heredity.
09  What is heredity?
10  What are some of the things we can learn by studying heredity?
11  And, why is heredity important?
12  During the next few minutes we are going to answer these questions,...
13  ... and others as we investigate heredity.
you 15  What’s the color of the fur of this calf?
observe 16  That’s right it’s brown.
17  The
6
heredity
acquired trait
mother of this calf also has brown fur.
18  Fur color is one example of a characteristic.
19  Another word for characteristic is trait.
20  This dog, for example, has many different traits.
21  Some of its traits include eye color,...
22  ...fur color and thickness,...
23  ... height,...
24  ... and head shape to name just a few.
25  All living things, whether they be plants or animals have many different traits.
26  In some cases traits are passed on from parents to their children, also called
offspring.
27  Heredity is the process of passing on traits from parents to offspring.

acquired traits
29  Think
about some of the things you do well.
30  Maybe you are good at playing sports.
31  Perhaps you are a very good musician.
32  Or maybe you’re an excellent reader.
33  Could
you do these things when you were born?
34  No, you could not do these things when you were born...
35  ...or even when you were a toddler.
36  Instead, you had to learn how to do these things.
37  With teaching and practice, you became better at them.
38  These learned skills are called acquired traits.
39  An acquired trait is something you learned or develop the ability to do. You
are not born with acquired traits.
40 
Graphic Transition – inherited traits
41  Think
about some of your basic physical features such as your eye color, your
height, and your hair color.
42  Did
you acquire or inherit these traits?
43  That’s right, you inherited these traits from your parents.
44  You can’t learn to make your eyes a different color...
45  ...and you can’t acquire the ability to make yourself taller or shorter.
46  Inherited traits are different from acquired traits.
47 
Graphic Transition – heredity and science
48  As
we mentioned earlier, heredity is the process of passing traits from parents
to offspring.
49  Genetics is the science of heredity.
50  Genetics has produced many things that have improved our lives.
51  For example, genetics has helped create new types of plants that produce
more food.
52  Genetics has enabled scientists to develop new medicines to prevent and cure
diseases.
53  Needless to say, the science of genetics has a big effect on our lives.

heredados
Nombre:
Un rasgo es una característica de un ser vivo. Los rasgos a menudo se
dividen en dos grupos: rasgos adquiridos y rasgos heredados.
Un rasgo adquirido es algo que aprendió a hacer. Uno no nace con rasgos
adquiridos. Entre los ejemplos de rasgos adquiridos están el aprender a
leer, o convertirse en un buen jugador de béisbol.
Los rasgos heredados son diferentes de los rasgos adquiridos. Los rasgos
heredados se transmiten de padres a crías. Los rasgos tales como el color
de ojos, la estatura y la forma de su cara son rasgos heredados.
Instrucciones: Describa cada uno de los rasgos mostrados. Luego decida si
es un rasgo adquirido o un rasgo heredado. Después explique su respuesta.
