Curated OER
Animal Organs and the Study of Reproduction, Embryology and Cancer
Students examine organs from dogs and cats to study reproduction, embryology, and the identification of cancer. They record their observations at both the gross and microscopic levels. They present their information to the class.
Curated OER
Flower Power
Students explore the parts of flowers and how they reproduce. They dissect flowers and observe the reproductive organs. Students observe anthers and ovaries of Tiger Lilies under a microscope. They investigate how insects and other...
Curated OER
Seed Types
Students dissect seeds. In this seed dissection instructional activity, students discover the anatomy of seeds. After dissecting seeds, students hypothesize and design the perfect seed to survive in a dry forest.
Curated OER
Pollinators and Wildflowers
Learners explore how plants depend on pollinators to reproduce. In this pollination lesson students dissect a local flower and collect and identify pollinating insects.
Curated OER
Plant Pollination
Students investigate methods of pollination for various flowers. In this plant biology lesson, students learn the parts of a flower and form a hypothesis about the method of pollination for the flower. They determine the validity of...
Curated OER
Plant Pollution
Students study the different parts of a flower and their functions. For this pollination lesson students study a flower under a microscope.
Curated OER
Elegant Embryology
Students observe embryogenesis in action through early stages of development of eggs. They observe cultures with dissecting and compound microscopes. They draw their egg, record any details and observe for changes. They compare their...
Curated OER
Exploring Food with Senses
Students explore properties of fruits and vegetables using their five senses. In this sensory activity lesson, students study fruit and vegetables through a microscope, using their sense of touch as they are blindfolded, and with their...
Curated OER
Wacky Water Critters
Students visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each organism...
Curated OER
Science: Bees: An Interdisciplinary Approach
Students investigate the world of bees and describe their characteristics. by identifying the bees' parts, they demonstrate how these parts function. In the lab, students dissect bees and view the various parts under microscopes. ...
Curated OER
Polytene Chromosomes from Salivary Glands
High schoolers use this laboratory procedure to outline the mechanism by which salivary glands are removed and prepared so that the polytene chromosomes may be observed.Drosophila virilis is used instead of Drosophila melanogaster...
Curated OER
Honey Bee Anatomy and Identification
High schoolers examine and dissect a worker honey bee to analyze the structures and functions of honey bees. They draw the structures they see and compare/contrast them to drawings or electron micrographs.
Curated OER
Fish Parasite Survey
Students survey and dissect as many fish as possible. They count nematodes, cestodes and crustaceans on the fish, fill out autopsy reports, and transfer data to a chalkboard data table. Students graph the results of the entire class...
Curated OER
Are Fruits And Vegetables Really Made of Cells?
Learners design and carry out an exercise to determine if a given fruit or vegetable is composed of cells. They dissect out sections of the fruit or vegetable, prepare stained slides, and make observations under a compound microscope.
Curated OER
Signs of Change: Tree Rings
Students identify and experiment with dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their...
Chymist
Determination of the Volume of CO2 in Pop Rocks
Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.
Curated OER
Root Caps and the Effect on Gravity Sensing
Students conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.
Curated OER
Flour Beetle
Learners observe the life cycle of the common flour beetle and make observations of its life stages. They also design and implement an investigation on food preference for the beetle and record data over a period of several months....
Curated OER
Dissolved Oxygen in an Aquatic Ecosystem
Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.
Curated OER
Invertebrate Diversity
Students observe different animals with bilateral symmetry. In this biology lesson, students compare how these animals move. They discuss the evolutionary history of observed animals.
Curated OER
Biological Concepts
Students perform a transection of a redworm. They discuss spinal cord injuries in humans. Students compare the ability of the redworm to regenerate the ventral nerve cord with the inability of humans to repair damage to the dorsal nerve...
Curated OER
Temperature Affects The Heart Rate
Learners relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature at...
Curated OER
Alfalfa Butterfly/Caterpillar Lifecycle Investigation
Students collect and record data. They model specimens. Students identify sex of butterflies. They analyze data. Students make conclusions based on collected data. They compare and contrast the different groups of insects such as...
Texas State University
Earth: Deposition and Lithification
Geology geniuses analyze sediment samples with a hand lens and sort according to physical characteristics. They also learn about the processes of cementation, compaction, and lithification within the rock cycle. The lesson plan is...
