Feb 29-March 4, 2016

6th grade-  This week we are studying the sun and moon.  We will learn about the appearance of the moon in relation to the sun and the Earth.  We will make a flip book of moon phases.  We will learn about lunar and solar eclipses.  We will study tides and the affect the moon has on them.

7th grade-  Ms. Jacobson’s class- Monday we will review and Tuesday we have the Genetics test.  Wednesday we will learn more about DNA and RNA. Thursday we extract DNA ourselves in a lab. Friday we will learn about genetic mutations.

Ms. Sussman’s class- Monday we will go over some of the study guide and DR and learn about selective breeding.  Tuesday and Wednesday we will work on Dragon Genetics.  Thursday is the test. I will have a study session on Thursday morning.  Friday we will finish and turn in Dragon Genetics.

Feb 22-26, 2016

6th grade-  On Monday we finished Weather Chart Project for two Cities.  On Tuesday, we reviewed Atmosphere.  Wednesday, we checked the study guides and played Kahoot and Socrative as a review.  Thursday is the Weather and Atmosphere Test.  On Friday we start the Planets unit.

Weather Study Guide 2014 shorter

7th Grade -In Mrs. Jacobson’s class, we are working on a Genetics project due Friday.  Wednesday we learned about Meiosis, or division of sex cells.  Thursday we will learn about Selective Breeding, sex-linked disorders, and genetic counseling.  Friday we will have presentations of Genetic Projects and start DNA unit.  Test Tuesday, March 1 on Genetics.

In Mrs. Sussman’s class- Monday we had a 50/50 chance lab. Tuesday we learned about Gregor Mendel and his studies with pea plants.  Wednesday we learned about heredity, alleles, and Punnett Squares.  We started a Sponge Bob Genetic worksheet.  Thursday we will look at genetic traits in ourselves.  Friday we will play Genetics with a Smile.  Test on Genetics-  March 8

Feb 8-12

6th grade-

All week we will work on an Adopt-A-City weather project in class with ipads.

 

7th grade-

Ms. Sussman’s class- Monday and Tuesday we will research frogs, and Wednesday we will dissect them!  Thursday and Friday we start Genetics and Heredity by learning about sexual and asexual reproduction.

Ms. Jacobson’s class- We are starting Genetics and Heredity. We learn about Gregor Mendel on Monday and Tuesday.  Wednesday we start Punnett Squares and learn about recessive and dominant traits.

Genetics Vocabulary

Vocabulary

Allele – one of the alternative forms of a gene that governs a characteristic, such as hair color

Gene – one set of instructions for an inherited trait

Chromosome – A threadlike linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information.

DNA – A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.

Genotype – The genetic makeup of an organism; also the combination of genes for one or more specific traits

Heredity – The genetic transmission of characteristics from parent to offspring.

Heterozygous – Having different alleles

Homozygous – Having two of the same

Inheritance – The passing of traits from parents to offspring.

Mitosis – process of cell division that form two new nuclei, each of which has the same number of chromosomes

Meiosis – process of cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells

Phenotype – The observable physical (or biochemical) characteristics of an organism, as determined by both genetic makeup and environmental influences

Probability – Measures the likelihood that something specific will occur

Punnett Square – A diagram that is used to predict an outcome of a particular cross or breeding experiment

Trait – A genetically determined characteristic or condition

Selective Breeding– the human practice of breeding animals or plants to have certain desired traits

Asexual Reproductionreproduction that does not involve the union of sex cells and in which  one parent produces offspring that are genetically identical to the parent

Interphase – The first stage of the cell cycle in which the cell grows and makes copies of chromosomes and organelles

Prophase – The first stage of mitosis and meiosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.

Metaphase – The stage of mitosis and meiosis during which the chromosomes are aligned along the metaphase plate.

Anaphase – The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle.

Telophase – The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.

Cytokinesis – The division of the cytoplasm of a cell following the division of the nucleus; marks the end of the cell cycle

Sex Chromosomes – Either of a pair of chromosomes, usually designated X or Y, that combine to determine the sex and sex-linked characteristics of an individual, with XX resulting in a female and XY in a male in mammals.

Sexual Reproductionreproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents

Homologous Chromosome – chromosomes that have the same sequence of genes and the same structure

(AC) trisomy – The condition of having three copies of a given chromosome in each somatic cell rather than the normal number of two.

(AC) karyotype – The characterization of the chromosomal complement of an individual or a species, including number, form, and size of the chromosomes.

(AC) genetic isolation – The absence of genetic exchange between populations or species as a result of geographic separation or of mechanisms that prevent reproduction.

(AC) selective pressure – Any cause that reduces reproductive success in a proportion of a population.

 

Feb 1-5, 2016

6th grade

We are learning about weather and wind.  We will have an open book quiz on Thursday.

7th grade

Ms. Jacobson’s class

We are working on a Body Systems Project on Monday and Tuesday.  Urinary System questions are due Monday and we are having a quiz on Tuesday.  Wednesday we are watching a virtual frog dissection lab, and Thursday we are dissecting our own frogs! We are also starting Genetics and will look at genetic traits in us–such as hairline, tongue-rolling, and ear lobes.

Ms. Sussman’s class 

We are finishing Body Systems and creating paper dolls showing one system.  We will review all body systems and have a test on Thursday. Friday we start Genetics
