Homework for today:

Vocab (for homework, copy off of blog into your vocab section):

Phenotype - organism's observable traits (what you can see on the outside).

Genotype - individual's pair of alleles for a specific gene or group of genes that determines a trait (what's in the genes).

Dominant - version of gene that appears with only one copy of a version of a gene (an allele).

Recessive - hidden trait, that is, the genetic trait that is not observed in a heterogeneous individual.

heterozygous - an organism that has more than 1 kind of allele for a characteristic.

homozygous - an organism that has only one kind of allele for a characteristic.

Punnett Square - diagram to show the likelihood of each outcome of a breeding experiment with known parent genes for a trait. See p. D-37.
 
PLUS: if you were absent on Monday, you need to include the following Notes and Vocab from Monday's lesson:
DAte:  1/26/15
Topic: What Are Your Genes? Investigating Human Traits
Obj: TSW collect data on six human characteristics and discuss causes of human variation.
Vocab from Monday's class: 
o        Allele - a variant or version of a gene. Ex: a gene could code for a round thumb joint, or a squared off thumb joint. One is Dominant (it wins), while the other is Recessive (it loses unless its the only one).
o        Characteristic - an observable or measurable feature of an organism and may be caused by one gene or many genes. Ex: eye color.
o        Gene - A specific sequence of DNA that determines one or more traits.
o        Genetics - the study of the location and behavior of genes, their passage to offspring, and of how characteristics are inherited.
o        Heredity - traits passed down to people or other organisms from their biological parents. Ex: eye color, tongue rolling, height potential, genetic diseases, arm span.
* Inherited - The passage of traits from parent to offspring.

Cell Biology unit test is tomorrow.  Students have a study guide, and were given 2-3 class periods to use textbooks in class to answer the questions in the study guide.

Tonight, students should review the study guide to prepare for tomorrow's test.

MidTerm exam is Next Thursday, 1/22/15.  Students will be given a new study guide tomorrow to help them prepare for the Midterm exam.

Review your Self Study Guide for the Cell Bio Unit Test coming up on Friday, January 22.

Read through it at least once, being mentally aware of what each word and phrase means as you read it. 

Then self-Quiz. Ask yourself each question as you cover the answers. Mark and re-read each answer until you can answer every question without reading the Study Guide.

Do it at least 3 times between now and Friday's test.

Friday: we'll start getting ready for the Mid Term test scheduled for Thursday, Jan. 22.

HomeworK:
Periods 1, 2: Worksheet  2-3 What are the Main Cell Parts?
Period 3: Students Explain what they lerned in class today about the contents of bacteria and animal or plant cells.  Parents are asked to write a note in their student's science notebook confirming what their student discussed with them about today's science class. 
Period 4:   Worksheet 2-4 What are Other Cell Parts?
