I started a company called CrunchLabs where we build a toy together and then I teach you all the juicy physics for how it works. So if you want to learn to think like an engineer and have really fun time doing it,…
Did you know that milk can be turned into cottage cheese with the help of enzymes? This video will show you what happens to milk when you mix it with pineapple juice. How do you think the milk will change? Written instructions are available on our website at https://www.sciencebuddies.org/stem-activities/milk-curdling-enzyme?ytid=amyaYsJLjss&ytsrc=description and https://www.sciencebuddies.org/teacher-resources/lesson-plans/enzyme-milk-curdling?ytid=amyaYsJLjss&ytsrc=description

The pKa of an acid is exactly the same as the pH HALFWAY to the equivalence point!
Then, Ka = 10^-pKa and you're done. Super easy.

Science Buddies 2011 Summer Science Fellows explain the chemistry and physics of the explosion that occurs when they ignite ethanol trapped in a film canister. You can see the full science experimental procedure for this science fair project idea--and do it yourself!— in 'Getting a Bang Out of Breath Spray: Studying the Chemistry and Physics of a Small Explosion' project idea…
Set on the beautiful beaches of Hawaii, “Reefs at Risk” explores the harmful effects some sunscreen chemicals have on coral reefs, marine life and people. In order to protect this fragile ecosystem, Hawaii lawmakers pass a bill to ban the sale of sunscreens with oxybenzone and octinoxate. To learn more and download a reef safe sunscreen guide go to www.ReefsAtRisk.org
This issue is not just relevant to people living in coastal areas or visiting coral reefs; the use of these products inland…
