8th Grade Life Science

Week 25

 Date Objective/ Procedure Handouts/ Labs Homework
2/28

The Periodic Table  & Balancing Equations-2 

1. Understand that atoms can neither be created or destroyed and understand that atoms can be rearranged to produce a chemical reaction- Law of Conservation of Matter

2.Determine whether the chemical reaction is a synthesis (building up), decomposition (breaking down), or replacement (rearrangement) reaction and the difference between an endothermic and exothermic reaction

3. Work in groups to balance chemical equations-Tutorial1 & Tutorial 2

NJCCCS 5.1  & 5.6

3/3

Where Does Food Come From
1. Science journal- list all the food you ate for lunch and then break down where the food came from naming the organism and whether it is a producer, consumer, or decomposer
Example- Ham & Cheese sandwich with mustard & lettuce on wheat bread
Ham- Pig (consumer)
Cheese- Milk- cow (consumer)- & Bacteria (decomposer)
Lettuce- lettuce plant (producer)
Mustard- mustard plant (producer)
Wheat bread- wheat plant (producer)

2.Read p. 14-16 in Populations and Ecosystems Resources Book- Where does food come from? to understand where the food we eat comes from and how the
Energy is passed from the Sun to Producers and Consumers

3.Use p. 33. Energy for Life- Sec 3 Content Mastery/ Reinforcement  to introduce new vocabulary: metabolism, respiration, fermentation, photosynthesis. producers, consumers

NJCCCS 5.1  & 5.6

33. Energy for Life- Sec 3 Content Mastery/ Reinforcement

3/4

Photosynthesis/ Respiration
1.
Science Journal Entry:

1.Explain what you think this means and is :
2.
CO2 + H2O --->C6H12O6 + O2
* Does this equation follow the law: Atoms cannot be created or destroyed- if not do something about it! 

2. Act out the lifecycle of a tree to better understand the birth, growth, development, reproductions, and then eventual death and decomposition starts the lifecycle again

3. Demonstrate the needs of trees/ plants and how competition alters how much of the necessities for life are available (Water, Sun, CO2) 
NJCCCS 5.1  & 5.6
