In this activity, students work in groups to apply their knowledge of intermolecular forces to identify nucleobase pairs; use a foldable paper model to mimic DNA replication, DNA transcription, and RNA translation; and decode a secret message.
When using standard thermodynamic values, the chemical reaction whereby ATP is converted to ADP is found to have a positive value for ΔG. This would imply the reaction REQUIRES energy. However, analyzing the process under physiological conditions shows that ΔG is in fact negative, as expected.
It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
Educators may be able to use these anthocyanin experiments to make a connection between the food we eat and the chemical principles that are employed to ensure that canned foodstuffs can be preserved properly.
Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
