RP Word Search Puzzle
In this literacy worksheet, students find the words that are related to the concepts that are the theme of the word search. New vocabulary is the focus of the puzzle.
Curated OER
DNA Extraction From Living Things
Students extract DNA from split peas. In this biology lesson, students hypothesize what DNA looks like and perform the experiment to verify their hypothesis. They explain the importance of DNA in living things.
Curated OER
What's on Your Plate?
Students demonstrate the path of food in the body. In this biology lesson, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.
Curated OER
Lost Baby
Students simulate the steps involved in creating a DNA fingerprint by the RFLP technique. They analyze RFLP patterns to determine the parentage of a missing baby.
Curated OER
Characterizing Drosophila Mutants
Learners investigate wild-type and several mutant varieties of Drosophila melanogaster, which are characterized and distinguished according to pteridine pigments. They discoverthat paper chromatography of the wild-type Drosophila results...
Curated OER
CONSTRUCTION OF A HEMOGLOBIN GENE
Students use research to see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They also understand how red blood corpuscles manufacture normal hemoglobin.
Curated OER
Why do we need Vitamin C in our diet? Or Why do we carry old inactive genes in our genome?
Pupils explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...
Curated OER
Pharmacology
In this pharmacology learning exercise, students compare excitatory and inhibitory neurotransmitters and how these work on the body. This learning exercise has 3 drawings and 13 fill in the blank questions.
Curated OER
Endocrine System
In this endocrine system worksheet, learners compare and contrast the glands associated with this body system plus review the four major classes of hormones. This worksheet has 25 fill in the blank statements.
Curated OER
Controlling the Code: Molecules at Work
In this DNA activity, students access a website to learn about how single-celled organisms function successfully. Then students pretend they are a bacterium and determine how to transport lactose across their cell membrane for food. This...
Curated OER
DNA Blueprint for Life
Students isolate DNA from different food sources. For this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
DNA Fingerprinting
Pupils experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
Curated OER
Wolf Pack in a Bottle
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
How to Conquer a Genetic Disease
Students study the details of DNA restriction analysis and how RFLP's are used to locate genes on a map of DNA.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
What Can Pseudogenes Tell Us About Common Ancestry?
Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...
Curated OER
Labs on A Chip
Students are introduced to DNA microarrays. They discuss how scientists and doctors use them and how they work. They complete a worksheet and discuss their findings.
Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
Curated OER
Insect Classification
Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.
Curated OER
DNA and RNA
Tenth graders research the history and discovery of DNA. Using their text, they label a basic DNA structure and the composition of genes. They explain how RNA and DNA differ from one other and discuss the processes of transcription and...
