Description: “My teacher gave me detention, I didn’t resist. Now she says it’s rude when I think like a Scientist. I had a hypothesis of why she acts insane, it’s all the bugs from her yogurt attacking her brain. It’s really more of an observation than a hunch, since everyday all she takes is a yogurt to lunch. ” “First of all, they’re not bugs!” “Ok germs then, whatever!” “They’re not germs and they can’t cross the blood brain barrier 9. Germs are harmful organisms that are single celled. Well, not viruses, they’re just DNA in a shell. Germs are pathogens 10 and we’re not talking about those, or your mites, or your mold, or why there’s zits on your nose. The vast and varied microscopic world’s all around. They’re inhabitants of you, me, the air, sea and ground. It is impossible to see it with your mirror; you would need a microscope to make it look clearer. The good news is that you are never really alone, the nearest metropolis exists on your brow bone. When you look at a square centimeter of your skin, I don’t think you could even begin to imagine, the variety of life that is residing on the only thing that you thought was yours alone. I’m talking about bacteria by the millions. In places like armpits, it’s closer to a billion. But your armpits aren’t even half as populated as your teeth, and sugar makes levels elevated. Bacteria are too small for just our eyes to see, in fact over a billion could fit into a pea. Inside of our bodies their numbers are the most high, but there’s billions of reason this doesn’t make us die. While some bacteria strains cause harm to our body, many others we need there to function properly. Like in our gut, where there’s more bacteria than the ground. Called commensal organisms, we want them around. First, they occupy empty space, so the bad ones can’t. Yogurt’s one way to increase these good inhabitants. Inside our stomachs and intestines this rule applies to the trillion plus tenants of microscopic size. Many helpful bacteria are there to kill the bad, or scrape residue from our gut like scouring pads. Others maintain and balance stomach acid levels, and acid’s vital to the function of this vessel. There are others who break down the milk sugar lactose, or who prevent mineral from forming kidney stones. They help rid our body of mutual enemies, and can breakdown our indigestible foods with ease. Certain bacteria may be cancer preventing. Some produce vitamins right where they're inhabiting, like the B vitamins and the more elusive K, which is not easily attained any other way. Bacteria may be a simple, single-celled thing, but don’t underestimate the effects they can bring. It does you no good to think about them with disgust; these bacteria aren’t an oddity, they’re a must.” Poetic Empiricist © 2015

Description: "First, we have the venus fly trap sea anemone, animal posing as flower, it waits patiently. To prey it's attractive or at least unassuming. Looking like a plant, they don't sense the danger looming. Curious creatures swim in for closer inspection, to become the anemone's next meal selection. The smallest movement or pressure will trigger the trap. The response is so sudden, it closes with a snap. Now enveloped in their venomous appendages, the captured and paralyzed prey are their hostages. If you think starfish are precious, then you've never seen, the elaborate ways of this killing machine. Their suction tube feet pry their prey's shell open a crack to shove its stomach in for an acid attack. This deadly guest, clams, scallops, and oysters can't expel, will start to dissolve them alive right in their own shell. The starfish pulls its stomach in after round one, and food goes with it to complete its digestion. Hydroids are animals who hang out and eat plankton. Colorful sea slugs will wait for their meal to be done, before they select and eat the hydroids that just ate. This is a novel 2-in-1 meal the slugs create. Steal an organism and its last meal in a bite. These slugs are gorgeous but deadly kleptoparasites. The basket star has the echinoderm charm looking like a huge starfish with curly arms, or a bundle of baby snakes in the sea. Its five arms covered in branches like a tree. Barbs cover their twisty, creepy arm branches, to entangle its prey as it advances. Enveloped in the harpoon-like tentacles, the prey's shoved in the mouth of the pentacle. If your friend's a moon snail, I hope you're not a clam. Never tell him where you live; you'll soon be in a jam. He'll show up uninvited and let himself right in. He'll stay long enough to eat, like he's your closest kin. There's no use in hiding, don't lock your shell up tight. He's got the tools to get in. You can't put up a fight. Kinda like a burgalar, he drills a tiny hole. Really like a kidnapper, cause you'll be what he stole. If that wasn't bad enough, there's a nasty enzyme, that's secreted from him mouth, employed to save some time. Finally his hole's complete, it now will spell your doom. All this time you've been waiting, closed off in your tiny room. The hole he made appears small but that is all he needs. You will be sucked through a tube, since that is how he feeds."

Description: The particular lesson should take place in late fall of first grade after students have demonstrated some familiarity with initial, medial and final sounds of words. At this point in the year, students also have a mastery of multiple vowel combinations and consonant blends that are instrumental in decoding larger words. While this introductory lesson was presented whole group, it continued with individual practice and reinforcement in small groups.
