Coin
Tosses and Probability: Invite students to describe situations in
which they have used a coin toss to decide an issue. Ask: Why did you toss
a coin in these situations? (Possible answer: It was the fairest way
to make a decision.) Why is a coin toss fair? (Each person has
a 50–50 chance of winning.)Why do you think we're talking about coin
tosses and probability? |

Materials: coin Expected
Outcome: The outcome of the coin tosses will vary. The more data, the closer
the outcome will be to the expected ratio of one “heads” to one
“tails.” Notes Complete
this as an entry in the journal (investigation) Have
students complete steps 1-2 in their journals. Answer
the first predicting questions |

that 5 in the denominator is the total number of parts that make up
100%. Use 5 coins to demonstrate
so that students can see that the total number is 5, not 8 (3+5). Show how 60% is 300%/5%. |

25%. Some students might observe that their results are similar to
Mendel’s results. Notes: Students should complete steps 1-3,
recording data in a table in thier journal. They should answer all of the
interpreting data questions in complete sentences |

Probability
Explains Genetic Crosses: Ask: How is this similar to
the outcome of a genetic cross? (The allele that each parent will pass
on to its offspring is based on probability.) What tool can be used to
predict the results of a cross? (A Punnett square, a chart that
shows all the possible combinations of alleles that can result from a genetic
cross) Refer students to Figure 7, and have student volunteers read each
step. Point out that combinations are simply pairings of the male and female
alleles from a particular row and column. Create
a Punnett Square using the Tt example from the coin cross lab for pea plant
height. Add to the paper pet
entry in the journal. |

Objectives: This
project will give students an opportunity to create a family of “paper
pets” based on phenotypes they have selected. Students will learn how traits
are passed from parent to offspring and how it is possible to predict the
outcomes of genetic crosses. After this Chapter Project, students will be
able to: •
model the inheritance of traits using a paper pet •
infer their pets’ genotypes •
predict the genotypes and phenotypes of their pets’ offspring •
communicate the results of genetic crosses in a class presentation. Determine
how much class time you want to use to introduce the project, then adjust the
class time for this activity. For more information on this project, click on
the Targeted Resources link. Punnett

Use one of the characteristics for each offsrping. there will be 1 repeat. add to the paper pet habitat for
storage. Use
this time to go around and check to make sure the pets are viable. stamp the entry. Work on
creating the paper pet poster or mobile. Mobile: on a hanger, put the two parents on
top. Hang the 6 punnett squares
and offspring off the bottom. Poster: Tape parents, punnetts and offspring
on a poster. Pets should be taped
on so that they can flap and both sides are visible. |

students not to get started on the test yet 3) Have the students write their names on
thier tests. 4) Explain that they will be answering
all of the questions directly on the test 5) Have the students look at questions 4
& 5. Explain that
"notation" means that's what they write down to describe the traits
of an organism. 6) Have the students turn to Page 3. Talk about the word bank. Not all of the words might be used. They might be used more than once or
not at all. Use them for the
following 2 sections. 7) Explain the "Modified
True/False." If the student
answers "False, then they need to correct the underlined word using
something from the word bank. 8) For questions 30-34, they need to use
complete sentences. 9) When finished, turn the test upside
