7 TH GRADE UNIT 6 LIVING SYSTEMS PROJECT By Mr Forrest 01/23/2017

LESSON 1: FORCE AND ENERGY IN LIVING SYSTEMS PGS. 328 -339 ENERGY TRANSFORMATION FORCE WORK

ENERGY PG. 330 • IS THE ABILITY TO CAUSE CHANGE TO A SYSTEM. • AN ORGANISM IS ONE TYPE OF SYSTEM. • FOR IT TO REMAIN ALIVE, CHANGES MUST OCCUR INSIDE AN ORGANISM EVERY SECOND OF ITS LIFE. • SUBSTANCES ARE BROKEN DOWN, BUILT UP, AND MOVED INSIDE AN ORGANISM'S BODY. • IF THE ORGANISM IS A SINGLE CELL, ALL OF THESE CHEMICAL REACTIONS OCCUR IN THAT ONE CELL. • IN SHORT, ALL ORGANISMS NEED ENERGY TO LIVE!

ENERGY TRANSFORMATION PG. 334 TAKES PLACE WHEN ENERGY CHANGES FROM ONE FORM INTO ANOTHER. NOT ALL FORMS OF ENERGY ARE DIRECTLY USEFUL TO ORGANISMS SO THEY MUST BE TRANSFORMED INTO A USEFUL FORM. FOR EXAMPLE, ORGANISMS SUCH AS PLANTS CANNOT STORE THE SUN'S LIGHT ENERGY IN THEIR CELL'S FOR LATER USE. IN PHOTOSYNTHESIS, THEY TRANSFORM THE LIGHT ENERGY INTO CHEMICAL ENERGY, WHICH THEY CAN STORE IN THEIR CELLS. ENERGY TRANSFORMATIONS ARE NOT COMPLETELY EFFICIENT. THIS MEANS THAT SOME OF THE ENERGY IN A TRANSFORMATION IS LOST TO THE ENVIRONMENT AS HEAT OR SOUND. SOME ENERGY IS RELEASED AS HEAT DURING NORMAL BODY FUNCTIONS SUCH AS DIGESTION AND MOVEMENT. ENERGY RELEASED AS HEAT HELPS MAINTAIN BODY TEMPERATURE.

ENERGY TRANSFORMATION PG. 334

FORCE PG. 335 IS A PUSH OR PULL EXERTED ON AN OBJECT THAT CAUSES THE OBJECT TO START MOVING, STOP MOVING, OR CHANGE DIRECTION.

FORCE PG. 335 PUSHING A FRIEND ON A SWING CAUSES THE FRIEND TO MOVE AWAY FROM YOU EXERTED A FORCE TO PUSH THE FRIEND AWAY. HOWEVER, IF EQUAL FORCE ACTS IN THE OPPOSITE DIRECTION ON AN OBJECT, IT WILL NOT MOVE(ENERGY CANCELS OUT). FORCES ARE ESSENTIAL TO LIFE PROCESSES. FORCES ACT ON AND INSIDE EVERY ORGANISM. FOR EXAMPLE, BLOOD IS PUSHED AROUND THE BODY BY A PUMPING HEART. TINY PROTEIN STRUCTURES INSIDE MUSCLE CELLS PULL ON ONE ANOTHER TO SHORTEN, OR CONTRACT, THE MUSCLE AND CAUSE MOVEMENT. CELLS EXCHANGE SUBSTANCES WITH ONE ANOTHER AND THEIR SURROUNDINGS BY MOVING MOLECULES. THE MOVEMENT OF MOLECULES ACROSS CELL MEMBRANES REQUIRES FORCE. MAIN FORCES: ON LIVING THINGS: GRAVITY AND PRESSURE.

FORCE PG. 335

WORK PG. 336 IS THE TRANSFER OF ENERGY TO AN OBJECT, CAUSED BY USING A FORCE TO MOVE AN OBJECT IN THE DIRECTION OF THAT FORCE.

VOCABULARY 6. HERBIVORE PG. 345 • Define, describe a consumer in your animals environment and provide 1 picture. • 1. An organism that only eats plants to get energy. • 2. A cow is a herbivore.

VOCABULARY 7. CARNIVORE PG. 345 • Define, describe a consumer in your animals environment and provide 1 picture. • 1. An organism that eats other animals to gain its energy. • 2. A killer whale is a carnivore.

VOCABULARY 8. OMNIVORE PG. 345 • Define, describe a consumer in your animals environment and provide 1 picture. • 1. An organism that eats both other plants and animals for energy. • 2. A bear is an omnivore.

VOCABULARY 9. FOOD CHAIN PG. 347 • Define, describe a consumer in your animals environment and provide 1 picture. • 1. The path of energy transfer from producers to consumers. • 2. Below is an example of a food chain.

VOCABULARY 10. FOOD WEB PG. 348 • Define, describe a consumer in your animals environment and provide 1 picture. • 1. Shows the feeding relationships of many different organisms in an ecosystem (a bunch of different food chains interacting). • 2. Below is an example of a food web.

LESSON 3: ENERGY AND MATTER IN ECOSYSTEMS PGS. 354 -365 • • 1. Energy 2. Matter 3. Law of conservation of energy 4. law of conservation of matter 5. energy pyramid 6. Water Cycle 7. Nitrogen Cycle 8. Carbon Cycle

VOCABULARY 1. MATTER PG. 356 • Define, describe a consumer in your animals environment and provide 1 picture. • 1. Matter is anything has mass and takes up space.

VOCABULARY 2. ENERGY PG. 356 • Define, describe a consumer in your animals environment and provide 1 picture. • 1.
