Curated OER
Using Ion Exchange Chromatography to Separate Proteins
Students explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.
Curated OER
What is Temperature?
Students study the effects of temperature and air expansion. In this temperature lesson, students discuss temperature and participate in a role play of low energy and high energy molecules. Students then discuss their activity and...
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
Curated OER
Ozone Tag
Young scholars explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then
describe the process by which chlorine or bromine compounds can break down ozone...
Curated OER
Basic Chemistry Review
Students experiment to show their knowledge of molecules and atomic structures. In this chemistry review lesson students participate in an activity and then fill out a worksheet.
Curated OER
Pauli's Magical Water
Students predict the shape of molecules using VSEPR theory. In this chemistry lesson plan, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
Curated OER
Take a Dip: Sticky Water
Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.
Curated OER
Learning Lesson: How it is Currently Done
Students create their own ocean currents by using everyday items. They examine the constant pushing of molecules that makes us feel wind. They discuss how the water moves in the Southern Hemisphere.
Curated OER
Clean Air
Students observe gas molecules in the atmosphere absorbing the light that goes through them.
Curated OER
Passive Causal Agents and the Omnidirectional Nature of Air Pressure
Students study passive causal agents, such as air pressure, in a system. They conceptualize air pressure as passive and omnidirectional, with molecules that make up the air bouncing off surfaces with which they have contact in all...
Curated OER
Kids for Conservation Lesson 1
Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...
Curated OER
Colored H2 Balloon Explosions
Young scholars perform an experiment in which they put different types of salts in a balloon, fill it with hydrogen gas, and ignite it. The electrons in the salt molecules are excited by the heat and release energy in the form of light....
Curated OER
