In this activity you can find out how to make your own Alka-Seltzer lava lamp. How will changing the temperature of the ingredients change the behavior of the colorful blobs in your laval lamp?
Make an Atom Lesson.
This activity is a guided discovery where students make chemical mixtures using sodium, learn about the Periodic Table, view salt under a microscope, and have a final result of bath salts for the bathtub
This video from KET traces the energy transformations that occur when coal is burned to produce electricity. Some of the mechanical processes are also described.
In this activity the temperature of a reaction is monitored for different concentrations of reactants.
This is a lab designed to allow students to create and collect gas through a simple acid-metal reaction.
This pathway introduces the units scientists use when making measurements and how to judge and express the meaning and level of confidence in a measurement.
In this adapted ZOOM video segment, cast members get hands-on in the recycling process by using old newspapers to make new paper.
This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.
This Chemistry experiment investigates physical changes, solutions, supersaturated solutions, and states of matter.
In this video segment adapted from ZOOM, cast members make a seismometer and experiment with different ways to make it register movement.
This video adapted from NASA explains how a magnetometer determines magnetic fields around planets.
This activity will take complex molecules and polyatomic ions the students have learned and construct them out of marshmallows and redhots. This develops understanding in VESPR structures and hybrid molecules.
This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas. Based on an activity presented by Olaf Runquist, Professor, Hamline University.
Two astronauts aboard the International Space Station (ISS) describe mass and weight and the differences between the two in this video from NASA’s Teaching From Space initiative.
Chemistry is often defined as the science of matter and how it changes. This pathway introduces the composition of matter and the physical and chemical changes it can undergo.
This activity is an inside lab experiment where the students combine primary colored liquids correctly to create a rainbow.
This activity is an inquiry lesson where students learn how to accurately read a thermometer and then set up an investigation to compare the temperatures of different materials or locations.
What can you do with chemistry skills? A lot of things, it turns out! Learn about the diversity of careers available to people interested in chemistry.
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
This video segment adapted from Discovering Women profiles Fermilab physicist and Harvard professor Melissa Franklin.
