LAB
This document summarizes a lab where a student dissected and compared the organ systems of a frog and fetal pig to those of humans. The student found that while frogs and pigs shared some organ similarities, such as liver structure, they also had differences. Notably, the frog's intestines were shorter than the pig's, and the pig had an umbilical cord while the frog did not. Through the dissection, the student learned about key organs like the heart, lungs, stomach and intestines in these species and how they function in digestion and circulation.
BIOLOGY FROG DISSECTION LAB
This document provides instructions for a frog dissection lab. It begins with terminology and safety instructions. Students are tasked with labeling the external anatomy of a frog, including identifying structures like the dorsal and ventral surfaces, limbs, eyes, tympanic membranes, and mouthparts. The internal dissection involves pinning and making cuts to expose organs. Key systems that are dissected and labeled include the digestive system (stomach, intestines, liver), urogenital system (kidneys, testes/ovaries), respiratory system (lungs), and circulatory system (heart). Questions assess understanding of anatomy like frog sex determination and organ descriptions. A list of terms to know for an exam is also provided.
Frog dissection lab answer key
The document provides instructions for dissecting a frog. It begins by describing how to determine the frog's sex by examining its forelegs. The external anatomy is then explored, labeling structures like the eyes, eardrums, nostrils, and skin coloration. Next, the internal mouth structures are located and labeled, including the tongue, teeth, and openings. The digestive, circulatory and respiratory systems are then dissected and their main organs and structures are identified and labeled in diagrams, such as the liver, stomach, intestines, lungs and heart. Finally, the urinary and reproductive systems are briefly described.
Immune system biology unit plan for the stem
This document outlines an immune system biology unit plan for a STEM school in Paterson, NJ. The plan aims to make science culturally relevant by valuing student experiences and using a deductive, multilingual approach aligned with AAAS standards. It connects scientific facts to students' real lives to help them care about learning, as the school population is overwhelmingly poor with many ELL and IDEA students.
Frog vs human
Humans and frogs share some similarities but also have key differences. Both humans and frogs will quickly remove themselves from hot water but find cold water comfortable. They also both have the ability to jump, though humans can run and jump farther than frogs. When threatened, both humans and frogs will make sounds seeking help. However, humans live on land in houses while frogs can live on land or in water. Humans are mammals with warm blood while frogs are amphibians with cold blood. Frogs also lay eggs while humans give birth. Finally, human skin is soft while frog skin is rough and scaly.
Cell Biology Lesson Plan
This lesson plan aims to teach students about the cell membrane and cell wall. It will discuss their structures, compositions, functions and histories. Students will participate in activities like a cell structure scramble game and building models of the cell membrane and cell wall. The lesson emphasizes that the cell membrane is a thin, semi-permeable bilayer that surrounds and protects the cell, while the cell wall is a tough, outer layer found in plant cells made mostly of cellulose that provides structure and prevents bursting.

Heat notes abbreviated
Fossil fuels are nonrenewable sources of energy that were formed from the remains of ancient plants and animals. They get their energy from the sun, which was originally stored by organisms that lived millions of years ago. Common examples of fossil fuels include coal, oil, and natural gas. This document also discusses temperature, thermal energy, and different temperature scales including Fahrenheit, Celsius, and Kelvin, noting that Kelvin scale defines absolute zero as the lowest possible temperature.
Energy types
Here are the steps to solve the roller coaster energy problems:
1. PE at point A = mgh = (20 kg)(10 m/s^2)(250 m) = 50,000 J
2. KE at point A = 0 J (velocity is 0 m/s at the top)
3. ME at point A = PE + KE = 50,000 J + 0 J = 50,000 J
4. KE at point B = 1/2mv^2 = 1/2(20 kg)(200 m/s)^2 = 40,000 J
5. ME at point C = ME is conserved. ME at point A was 50,000 J.

What is energy2010
1. Energy is the ability to do work or cause change. Work is done when a force causes an object to move, and is measured in Joules.
2. Kinetic energy depends on an object's mass and speed, and is calculated as KE=1/2mv^2. Potential energy depends on an object's mass and height, and is calculated as PE=mgh.
3. Mechanical energy is the total of an object's kinetic and potential energies, or ME=KE+PE. As an object moves, its kinetic energy increases as its potential energy decreases, keeping the total mechanical energy constant.
Intro to Energy
The document discusses energy and how it was used in the past compared to today. It prompts the reader to list what they know about energy and what they want to learn. It then asks the reader to define energy and provide 10 everyday ways they use energy. The document discusses how ancestors lived without modern conveniences like light bulbs, cars, and air conditioners. It prompts the reader to think about whether ancestors required energy in their daily activities. The reader is then asked to read a story about life 100 years ago and discuss differences in energy usage between the past and present. Finally, the document prompts the reader to draw an illustration showing the relationship between energy and work and explain their drawing.
Invertebrate review chart
The document discusses lower invertebrates and provides review questions about their characteristics and complexity. It asks questions about the simplest and most complex invertebrate phyla, types of symmetry, and parts of the crayfish. Review questions cover characteristics of flatworms and roundworms, differences in complexity between sponges and mollusks, common characteristics among listed groups, and types of symmetry. The document then shifts to discussing higher invertebrates and provides additional review questions comparing them to lower invertebrates.
Vertebrates review chart
Mammals, birds, reptiles, amphibians, and fish are the five classes of vertebrates. Mammals are warm-blooded and nurse their young, while birds are also warm-blooded but lay eggs. Reptiles, amphibians, and fish are cold-blooded and many reproduce by laying eggs, though some amphibians hatch as larvae.
Mammals notes
Birds and reptiles can be compared and contrasted using a Venn diagram. Some key differences are that birds are endothermic and have feathers for insulation, while reptiles are ectothermic and have scales. Both lay eggs but birds care for their young after hatching while most reptiles do not provide parental care.
Bird notes
Birds have adaptations for flight including feathers and hollow, lightweight bones. They lay amniotic eggs and maintain a high body temperature through endothermy, panting to cool off and eating frequently. Birds also have a four-chambered heart and double-looped circulatory system.
Reptile notes
This document discusses the characteristics and adaptations of reptiles. It notes that reptiles and amphibians both share characteristics with chordates. Reptiles have developed adaptations to live on land such as dry scales, thick skin, and amniotic eggs to prevent water loss. Their circulatory system includes a three-chambered heart and double-looped circulatory system. Reptiles are ectothermic and must rely on external heat sources to regulate their body temperature.
Reptile and bird notes
Fish and amphibians share characteristics with all chordates, such as having a notochord and dorsal nerve cord. Reptiles evolved adaptations like scales, thick skin, and amniotic eggs to prevent water loss and live on land. Reptiles have three-chambered hearts and double-looped circulatory systems, and are ectothermic, maintaining their body temperature through their surroundings. Birds further adapted for land with feathers for flight, thin hollow bones, and the ability to regulate their own high body temperatures through panting and a high metabolism.
Frog info packet
This document contains a series of slides from a frog dissection guide. It lists and numbers various external and internal structures of frogs such as the mouth parts, internal organs, and reproductive systems of male and female frogs. The slides provide labels for anatomical structures like the ventricle, auricle, liver, gallbladder, intestines, kidneys, testes, ovaries and more.
Frog dissection pictures and diagrams
Frog dissection is a common biology lab activity where students examine the internal anatomy of frogs. The purpose is for students to learn frog anatomy through direct observation of organs like the heart, lungs, stomach and intestines. This document likely contains diagrams and pictures to help guide students through the dissection process and identify internal structures.
Amphibians notes
Amphibians are vertebrates that breathe through lungs and thin, moist skin. They have a three-chambered heart and double-loop circulatory system that is more efficient than the single-loop system of fish. Amphibians go through a metamorphosis where tadpoles with tails and gills transform into adults without tails that use lungs to breathe on land. There are three main groups of amphibians: frogs and toads, salamanders, and caecilians.
Fish notes
1. Vertebrates share four key characteristics: a notochord, hollow nerve cord, pharyngeal gill pouches, and a tail.
2. Fish are the largest and simplest group of vertebrates. They are ectothermic, have fins and scales, and a lateral line.
3. Fish have a closed circulatory system with two heart chambers that pumps blood to the gills and body for gas exchange.
Crayfish conclusion
Crayfish are advanced arthropods that belong to the phylum Arthropoda. They have a segmented body adapted for movement, digestion, and survival. Their form fits their function, with organs and symmetry suited to their lifestyle in waterways.
Crayfish dissection diagrams
This document contains diagrams and descriptions of the external and internal anatomy of a crayfish. It identifies and describes key external structures like the cephalothorax, abdomen, appendages, eyes and sensory organs. Internally, it outlines the location of organs like the heart, hepatopancreas gland, stomach and nerve cord. Descriptions are provided of both male and female reproductive structures and swimming appendages.
Arthropoda & echinodermata notes
Arthropods are the most successful group of animals on Earth, making up over 75% of all animal life. They have a segmented body, jointed appendages, a hard exoskeleton that many molt to shed and grow, and undergo complete metamorphosis from egg to adult. Arthropods have bilateral symmetry, organs and systems, eat a wide variety of foods, and reproduce sexually. They are found globally in nearly all environments.
Molluska & annelida notes
The document provides information about mollusks and annelids. It notes that mollusks are one of the most diverse animal groups, have a radula and live in various habitats. Their body plans include bivalves, gastropods and cephalopods. Annelids are segmented worms that fertilize soil, have a closed circulatory system and brain, and move by creeping along using muscles.
Flatworms roundworms notes
Flatworms and cnidarians share some basic characteristics like having simple tissue organization but differ in key aspects like flatworms having bilateral symmetry and a digestive system while cnidarians do not. Some flatworms like tapeworms are parasitic and can infect humans, causing illnesses if meat or water is ingested that contains the parasite larvae. Roundworms also infect many humans and include parasites like hookworms that burrow into the skin and travel to the bloodstream, feeding on blood.
Porifera cnidariannotes
This document provides information about sponges and cnidarians. It discusses their defining characteristics, including that sponges filter feed without a digestive system, have skeletons made of spicules or spongin, and can reproduce asexually through budding. It also notes that cnidarians have radial symmetry, prey on other organisms using stinging cells called cnidocytes, and can reproduce both sexually and asexually through budding. The document compares and contrasts these two early animal phyla.
