Feeding Paramecia
Young scholars prepare a slide of Paramecium cultures and observe (through a microscope) the organism's thin transparent membrane and what happens as they "feed" them stained yeast cells. They sketch the path the ingested yeast takes as...

Transformation With A Firefly Gene
Learners understand the process of bacterial transformation through experimentation. They describe the function of two important genes of the pBestLuc plasmid. They explain how to induce competence in E. coli cells.
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.

Modelling the Human Ventilation System
Why is breathing so difficult for asthma sufferers? To find out, learners build their own lung models in the investigation (from a British website, hence the term ventilation system instead of respiratory system). Using different-sized...
Curated OER
Energy, Matter, and Organization
Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

Investigating the Method by Which the Body Defends Against Pathogens
High schoolers explore disease caused by bacteria and viruses, how they are transmitted, and how they exert their effects on their hosts. They explain how diseases, such as AIDS, are spread by exponential growth.
Curated OER
Translation and Proteins
Young scholars follow the steps of translation and identify the reactants and products of translation. They able to explain that proteins are made of amino acids which are coded for by RNA. Students are able to give examples of...

Testing Leaves for Starch: the Technique
Like good scientists, kids often want to see first-hand why things are as they are; they can do just that in the starch-testing photosynthesis activity found here. Depending on the age of your pupils, you may wish to do the investigation...
Curated OER
Extraction of DNA from White Onion
Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
MITOSIS
Tenth graders examine the process of mitosis on a laser disc. They examine mitosis in an onion utilizing the microscope.
Curated OER
Protein Synthesis Activities
Students participate in a teacher-guided activity to teach about protein synthesis. Student roles include one person as the DNA molecule, another is a single stranded sequence of complementary mRNA.
Curated OER
Ion Flow in Neurons
Student perform an experiment in which they determine the velocity of ion flow in an electrotonic potential and compare it to the velocity of action potentials. They record and analyze their results.
Curated OER
Strawberry DNA Extraction
Students explore the DNA of strawberries. In this science instructional activity, students extract the DNA of strawberries. Students complete a lab report.
Curated OER
Protein Synthesis Activities
Students compare the process of protein synthesis in an analogy. They simulate the process of protein synthesis kinesthetically using index cards and write a paragraph to explain the process.
Curated OER
Multiple Alleles
Students observe models of the ABO blood system including erythrocytes, antigens, and antibodies. They investigate the antigens that result from certain allele combinations and move antibodies to determine whether agglutination occurs...
Curated OER
When Microbes Attack
Students study how the body defends itself against the invasion of harmful microbes and how certain types of drugs can provide assistance. They design and execute their own experiments to test whether increasing the number of types of...
