Effect of Bicarbonate on Photosynthesis [AP Bio Lab 3.5] Lab Hamster 2023-10-10 | Hey bio friends! This video shows an updated version of the floating leaf disk lab I use with my AP Biology classes. The new procedure is streamlined to make teacher prep and student set up of the experiment less time consuming and easier. The data collected in this experiment has shifted to the volume of oxygen generated by leaf disks as a function of bicarbonate levels (0-4% m/v) of tested solutions. You'll never need to worry again about getting leaf disks to sink again!Here is a link to a video discussing the results of this experiment.[COMING SOON!]Photosynthesis is covered in Unit 3.5 of the AP Biology Course & Exam Description (CED).

Density of Water [AP Bio Lab 1.1] Lab Hamster 2023-09-27 | Hey bio friends! I created this tutorial video showing a lab conducted to collect data to experimentally determine the density of water. The lab also serves as an introduction to using a micropipette.In the lab, students use micropipettes to transfer water into a test tube in 200 μL (0.200 mL) increments. The mass of the water is measured after each transfer. A graduated test tube is also created in the lab that can be used for later experiments to quantify amounts of gas produced in biological reactions.Here is a link to the video which shows how the data collected in this experiment can be analyzed in Google Sheets using linear regression.youtu.be/qZnHnrlQ-IQDensity is one of the important emergent properties of water covered in Unit 1.1 of the AP Biology Course & Exam Description (CED). #apbio #apbiology #statistics

🧪Joule-Thomson Effect [an endothermic process] Lab Hamster 2023-03-23 | In this video, we explore the fascinating phenomenon of Joule-Thomson cooling that occurs when baking soda and vinegar react to produce carbon dioxide. Joule-Thomson cooling is a process in which a gas cools as it expands against a pressure difference. When baking soda and vinegar react, they release carbon dioxide gas, which expands rapidly and cools down. This reaction can be used to demonstrate the principles of thermodynamics and the Joule-Thomson effect in a simple and fun way.We will begin by showing you the materials needed to conduct this experiment, including baking soda, vinegar, a plastic bottle, and a temporal scanner. Then, we will walk you through the step-by-step process of mixing the baking soda and vinegar producing carbon dioxide gas. The expansion of the gas causes the temperature to drop!This video is perfect for science enthusiasts, students, and anyone curious about the fascinating world of thermodynamics. So sit back, relax, and join us on this cool scientific journey!SUBSCRIBE: tinyurl.com/y29j7ruq Check out my website at: mrpauller.weebly.comOther Video Experiments:Silver Tree - youtu.be/lgL-VB1r-oQReaction of Pb(NO₃)₂ + KI - youtu.be/gehTqbGsZ8wFirework Chemistry, Flame Tests! - youtu.be/5k4LojhidG0Which Metal Reacts Faster, Mg or Al? - youtu.be/tiGZlaiUYwcEnzymes in Your Spit, Salivary Amylase - goo.gl/TcLm2BSolubility of a Gas in a Liquid (Messy!) - goo.gl/ZqYkjeLab video by Noel PaullerMusic courtesy of Lofi Records: Through the Wormhole by Purrple Cat #ScienceExperiment #Chemistry #Science

Cicadas 2024, what will they sound like? Lab Hamster 2021-05-21 | 2024 will see a dual emergence of two broods of periodical cicadas! The 13 year Brook XIX and 17 year Brood XIII will both arrive this spring. It is possible the city of Springfield, IL will witness both broods emerging.The Brood X periodical cicadas emerged in May, 2021. This video includes audio of the distinct calls made by the three different species of 17 year cicadas (Magicicada septendecim, Magicicada septendecula and Magicicada cassini. The 13 year cicada species includes Magicicada tredecim, Magicicada tredecassini, Magicicada tredecula and a new species discovered in 1998 called Magicicada neotredecim. The 13 year cicadas are nearly identical to the 17 year species in all traits other than how frequently they emerge.SUBSCRIBE: tinyurl.com/y29j7ruq Image credits:Magicicada septendecim - Agricultural Research Station commons.wikimedia.org/wiki/File:Magicicada_septendecim.jpgMagicicada septendecula - Fontaine K, Cooley J, Simon C (2007)commons.wikimedia.org/wiki/File:Magicicada_septendecula_male_(Brood_IX)_-_journal.pone.0000892.g003C.pngMagicicada cassinii - Fontaine K, Cooley J, Simon C commons.wikimedia.org/wiki/File:Magicicada_cassini_female_ovipositing_-_journal.pone.0000892.g005.pngCalling song of Magicicada septendecim by Fontaine K, Cooley J, Simon C commons.wikimedia.org/wiki/File:Calling_song_of_Magicicada_septendecim_-_pone.0000892.s001.ogaCalling song of Magicicada cassini by Fontaine K, Cooley J, Simon C commons.wikimedia.org/wiki/File:Calling_song_of_Magicicada_cassini_-_pone.0000892.s002.ogaCalling song of Magicicada septendecula by Fontaine K, Cooley J, Simon C commons.wikimedia.org/wiki/File:Calling_song_of_Magicicada_septendecula_-_pone.0000892.s003.ogaA Magicicada chorus containing M. septendecim, M. cassini, and M. septendecula by Fontaine K, Cooley J, Simon C commons.wikimedia.org/wiki/File:A_Magicicada_chorus_containing_M._septendecim,_M._cassini,_and_M._septendecula_-_pone.0000892.s004.ogaWeVideo Stock Footage#Cicada #Cicadasounds
