Determination of the percentage of Acetic Acid in Vinegar
Students determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...
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
Plant And Animal Cells
Students identify parts of plant and animal cells and describe the functions of each part. They distinguish between plant and animal cells. After a lecture/demo, students perform experiments which help them construct models of plant and...
Curated OER
Sea Floor Spreading
High schoolers recreate sea-floor spreading and the pattern of magnetic stripes that are created by different configurations of plate boundaries. They see how transform faults work.
Curated OER
How Can We Observe Genetic Variation Within a Species?
Students observe intra-species variation by completing standard microbial streaking procedures. They collect data from which they draw observations and complete a worksheet.
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
How Can We Determine the Concentration of an Unknown Solution?
High schoolers participate in experiments to help them determine the concentration of an unknown solution. They graph a standard curve and plotting the relationship between the concentration and the amount of light needed. They discuss...
Curated OER
Mini-Molar Concentration of HCI
High schoolers work together to create mini-molar concentrations of HCI. They record and analyze their data for specific results. They answer discussion questions to complete the lesson plan.
Curated OER
Enzymatic Reaction
Students explore the effect enzymes have on reactions. They demonstrate the process of enzymatic reaction by making cheese. after experimentation, they answer a series of questions.
Curated OER
Iron Filings
Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...
Curated OER
An Introduction To Material Sciences
Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...
Curated OER
Physiology Activity Perception and Behavior
Students conduct an experiment to determine a fly's ability to detect sugar, its behavioral response, how a previous experience may alter the response, if a fly can be tricked, and how human sensitivity compares to a fly.
Curated OER
Periodic Table & Its Trends-Day 1
Students are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...
Curated OER
Transmission of Disease
Students provide names of viral diseases that they would possibly like to be infected with today; listing them on the Smart Board. They then come to an agreement about what virus to use and use beakers of fluids to simulate how viruses...
