8th Grade Life Science

Week 31

 Date Objective/ Procedure Handouts/ Labs Homework
4/15 Population Dynamics-1

1. Review data acquired by ecologists working at Mono Lake and determine the biotic and abiotic factors that affect population size

2. Watch a video that discusses the abiotic  factors in an ecosystem: water, temperature, air, soil, sun, weather, and the cycles in nature to understand the effects for the biotic members and take notes in an organized chart

3. Analyze graphs of data from Mono Lake to determine how the ecosystem changes when the abiotic and biotic factors change

NJCCCS 5.1  & 5.5

 

 

 

41 Cycles in Nature/ Energy Flow

Read text p.728-737  41. Cycles in Nature/ Energy Flow
Prepare for Test: Terrestrial, Aquatic Mini ecosystems, Mono Lake food web and analysis, Cycles in Nature- binder p.36-41 notes

4/16 Ecosystems Review

1. Analyze graphs of data from Mono Lake to determine how the ecosystem changes when the abiotic and biotic factors change

2.Go over:  39. Reinforcement: Living Earth/Interactions within communities & 40. Overview: The Nonliving Environment/ Abiotic Factors  to understand the dynamics of populations and communities within an ecosystem

3. Reading: Populations and Ecosystems: Limiting Factors p. 22-24 Answer Think Questions in Science Journal

4/17

Ecosystems Evaluation

1. Demonstrate knowledge on a test: Terrestrial, Aquatic Mini ecosystems, Mono Lake food web and analysis, cycles in nature, populations, communities, ecosystems

2. Demonstrate knowledge on an evaluation: niche, habitat, symbiosis, individual, population, community, ecosystem, abiotic factors

3.  Use multimedia simulation (open for directions) to determine the transfer of genetic information during the breeding of Larkeys and the traits that result: Foss Populations & Ecosystems Website

NJCCCS 5.1  & 5.5

4/18

Intro to Genetics

1. Understand that a genotype is  an organisms particular combination of paired alleles while the phenotype represents the expressed trait

2. Understand that genotypes can be heterozygous or homozygous and that 1 dominant allele means that the dominant trait will be expressed

3. Participate in an activity to show the probability of the expression of different traits and determine the genotypes and phenotypes of the individuals by using Punnett Squares to determine the genotypes and phenotypes of offspring

NJCCCS 5.1  & 5.5 

23.Easter Egg Genetics

42Overview Heredity/ Genetics

Journal: What is your definition of genetics?

 

Punnett Square- Exit Bb X Bb

Read text p.124-147 42.Overview Heredity/ Genetics

4/19

Genetics Terminology

1.Add vocabulary: Populations and Ecosystems Vocabulary 15-17  to understand the terms associated with genetics: cell, nucleus, chromosomes, allele, gene, genotype, phenotype, dominant, recessive, egg & sperm, punnett squares- Genetics 101 Videos- Crash Course

2.  Look at four of their features to determine what trait they have: little fingers straight or bent, earlobes attached or not, hairline forms a widow's peak or not, and tongue can curl or not.

3.Study a population of larkeys, a make-believe animal, to analyze their traits by reading " A Larkey Yammer"- p. 56-57 Populations and Ecosystems Resources Book-Practice decoding the genotype of a larkey to discover what traits it has.- Draw & Name

NJCCCS 5.1  & 5.5

 43. Genetics Vocabulary
