WILD FLOWER IDENTIFICATION GUIDE (ID GUIDE) Awesome Science Teacher Resources. Make a leaf skeleton. Remove leaf tissue to see a beautiful "skeleton" of veins! This project can be done with a variety of fresh leaves in the spring, summer, or fall. (Adult supervision recommended.) Pin It What You Need: Leaves (choose large leaves that are colorful, not dried out)Sodium carbonate (washing soda)Metal potForceps or tweezersPaintbrush What You Do: Measure 4 ¼ teaspoons of sodium carbonate (or weigh out 20 g with a balance) into the pot.Dissolve the sodium carbonate in a half liter (a little more than 2 cups) of water.Heat the mixture on the stove.
What Happened: The part of the leaf you can see now is a complex pattern of hollow veins making up the leaf's skeleton. Hands-on Activities for Teaching Biology to High School or Middle School Students. By Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts.
Many of our activities are explicitly aligned with the Next Generation Science Standards, as indicated by (NGSS) in the descriptions below and the links to the right. Additional information is provided in Summary Tables and in the Teacher Preparation Notes for these activities. To accommodate limited budgets, most of our activities can be carried out with minimum equipment and expense for supplies. Additional resources for teaching biology are available at More Minds on Activities for Teaching Biology. Read More Intro and Biological Molecules Is Yeast Alive?

Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas. But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Your family pet, Fido the dog Your little sister's big toe Bugs you caught in the yard Step 1: Blender Insanity! Put in a blender: 1/2 cup of split peas (100ml) 1/8 teaspoon table salt (less than 1ml) 1 cup cold water (200ml) Blend on high for 15 seconds.
The blender separates the pea cells from each other, so you now have a really thin pea-cell soup. Step 2: Soapy Peas Pour your thin pea-cell soup through a strainer into another container (like a measuring cup). Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix. Let the mixture sit for 5-10 minutes. Pour the mixture into test tubes or other small glass containers, each about 1/3 full. Why am I adding detergent? Cornell University - Institute for Biology Teachers. Adventures in Field Botany / Illustrated-Glossary. Leaf Morphology: Phyllode/ Cladode: modifyed stems that act as leaves. Ensiform: leaves sharp edges, taper into a slender point (fern) Stellate: hairs come up like fingers.
Looks like cluster of hair. Peltate: "petiole joins to the center" in leaves. With hair, at the end of each single hair, a flat, round, part is attached. Glossary of Terms: WHORLED - more than two (2) opposite leaves. OPPOSITE - leaf nodes are on opposite sides of twig. ALTERNATE - leaf nodes alternate in pattern along branch. DECUSSATE - Arranged on a stem in opposite pairs at right angles to those above or below, resulting in vertical rows of leaves.
PALMATE - consisting of leaflets or lobes radiating from the base of the leaf. CAPSULE - a hollow dry fruit with 3+ locules (chambers) Dehiscent = splits open to release the seed. Indehiscent: remaining closed, do not split open at maturity. Capsule Types- Dehiscent: Capsule breaks to release fruit Indehiscent: This is a drupe, no hard capsule that is made to split open Root Index. What Animals See! Infographic. Seaquence. Discover Life. 6 Animals with Immunities Humans Would Kill For. AS HUMANS, WE OFTEN SEE OURSELVES AS THE FOREFRONT OF EVOLUTIONARY DEVELOPMENT. After all, we have consciousness, global communication, and pizza with cheese in the crust. But there are some animals with abilities so amazing you have to wonder if we aren’t the ones who are a bit behind in the evolutionary race. 1. The Naked Mole Rat The naked mole rat is a burrowing creature from East Africa. These critters are the only known mammals who can’t contract the big C.
To study the effects, scientists injected buck naked mole rats with cancer. From the looks of it, another danger they won’t have to worry about is over-adoption. What makes this extra-bizarre is the fact that humans share one of these two genes, but the human version of the gene does nothing to inhibit cancer. That’s not the only freaky thing about the naked mole rat. 2. Mandrill monkeys are baboon-like creatures that enjoy African rainforests.

This page describes the science behind Foldit and how your playing can help. What is a protein? Proteins are the workhorses in every cell of every living thing. Your body is made up of trillions of cells, of all different kinds: muscle cells, brain cells, blood cells, and more.
Inside those cells, proteins are allowing your body to do what it does: break down food to power your muscles, send signals through your brain that control the body, and transport nutrients through your blood. What are amino acids? What shape will a protein fold into? Why is shape important? What do proteins do? Proteins are present in all living things, even plants, bacteria, and viruses. Photosystem I is a collection of proteins in plants that captures sunlight for photosynthesis.Luciferase catalyzes the chemical reaction that makes fireflies glow.Hemagglutinin helps the influenza virus invade our cells. 25 Most Beautiful Animals Photography on StumbleUpon. Don't Feed the Plants! Everyone should be familiar with the genus Dionea or "Venus Fly Trap" above, but the vegetative world is home to plenty stranger, and while perhaps not as adrenaline-pumping as Crustaceans or as gruesome as Amphibians, plants provide food, shelter and oxygen for the entire kingdom Animalia, so they certainly deserve the spotlight once in a while, and their weirdness does not disappoint.
Rather unremarkable in appearance from above, these tiny aquatic plants are actually carnivorous, and display one of the most sophisticated mechanisms (carnivorous or otherwise) in the entire known plant kingdom. The "bladders" of the plant's namesake are thousands of tiny, sac-like pods which hang from submerged branches, each equipped with a hinged "door" and membranous seal held shut by a delicate equilibrium of pressure. At the slightest touch by some tiny insect, crustacean or even protozoa, the seal is broken and the bladder floods with water, sucking in the prey for digestion.
