Materials to Prep Giant tables Food web tables Food web label teachers desk, pass out before 2 nd activity in lab Bellwork HAVE SLATE, MARKER & ERASER ON DESK!!! 1.List all of the ingredients from the last meal you remember 2.For EVERY ingredient, describe where its energy came from (what did it eat, or how did it make its own energy?) 3. Look back in your scientific method notetakerwhat goes in each of the 3 parts of a hypothesis? (NOT if, then, as measured by) 4.What is the procedure for diSmiSSal? (hint, think about the 3 Ss) ***Review your biome poster notes from yesterday Bellwork 1. Look at the 8 levels of organization on the back of your notetaker from yesterday. Come up with your own real life version for each level (see my example below- you can use Earth ) Biosphere = Earth Ecosystem = Rainforest Community = trees, birds, and bugs in the area Population = all of the toucans Organism = a single banana tree Tissue/Organ = A panthers heart Cell = A brain cell Atom/Molecule = H2O Example! Energy Flow & Roles of Organisms (notes on lined paper) Autotrophs Autotroph = organism that makes food for itself (producer) Selffood Talk to Your Partner Based on the definition we just wrote down, what are some examples of autotrophs? Autotrophs Autotroph = organism that makes food for itself (producer) -Ex: plants & some bacteria Selffood Heterotrophs Heterotroph = organism that eats other organisms (consumers) Different food I must be a heterotroph, since I cant synthesize these! Heterotrophs Heterotroph = organism that eats other organisms (consumers) -Examples: animals, fungus, bacteria Different food Try this! (5 mins) At your lab table: Work as a group to quickly sort the cards & use arrows to show which direction energy is flowing Example: 2 Big Categories of Organisms Make a T-chart Autotrophs/ Heterotrophs/ Producers Consumers There are two types of autotrophs/producers Autotrophs 1. Phototroph : use energy from sun to make food (photosynthesis) Autotrophs 2. Chemotrophs : use energy from chemicals to make food Ex- Bacteria in deep sea vents There are many types of heterotrophs List as many types as you can Hint: A cow is one type Heterotrophs 1. Herbivores : eat ONLY plants Heterotrophs 2. Omnivores : Eat BOTH plants & animals Heterotrophs 3. Carnivores : eat ONLY meat Heterotrophs 4. Scavengers: feed on dead organisms Ex. Vultures, Shrimp, Mealworms! Heterotrophs 5. Decomposers : Absorb dead materials/waste & break them down into fertilizers for plants Ex. bacteria, mushrooms Try this! (Part 2) Add organism terms to the cards at your lab table Example: Omnivore Closure 1.On back of notes- Draw a simple food chain for your critter, with at least 5 organisms. 2.Label each organism with vocab- herbivore, phototroph, etc. 3.When finished, put together your critter & drop it off in the front basket
