Ocean Acidification
If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Antacid Lesson Plan
Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Working with Moles
In this moles worksheet, students read about mass, formula mass and moles. They calculate the masses of given numbers of moles of compounds and they calculate the number of moles of given masses of compounds.
Curated OER
Formula Mass
In this formula mass worksheet, students read about molecular substances and their formula masses. They find the formula masses for six compounds using the atomic masses of its elements.

Avoiding Carbon Dioxide Emissions from Burning Fossil Fuels
High schoolers calculate stoichiometrically the amount of carbon dioxide that would be emitted from burning a mole of varios alkanes that comprise fossile fuels. If the energy released from burning a mole of these alkanes is known, then...
Curated OER
Micro-Magic With Sticky Ions
Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
Curated OER
Photosynthesis and Respiration
Eighth graders differentiate photosynthesis and respiration. In this biology lesson, 8th graders draw a diagram explaining these two processes. They answer a quiz after the lesson.
Curated OER
Unknown Element Project
Learners work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a report as...
Curated OER
Collisions Drive Reactions
In this reactions activity, students determine what must take place in order for a reaction to occur. Students complete 6 short answer questions.
Curated OER
pH and Titration
In this pH learning exercise, students review the titration procedure and the significance of the stoichiometric point. This learning exercise has 2 problems to solve.
