 Hey, everybody We're back We're back to finish our second half of the chemistry content in our biology course We can look at this like dude. Awesome. We are already halfway finished with our chemistry Or we can think about it like wait a minute if we have only one more lecture of chemistry How are we gonna get it all covered? I'm in the second part of that equation wondering. Oh, man I'm gonna start recording this video lecture for you and If you look at the little menu that's right down here. We have eight Topics in today's lecture that are very very dense So we're gonna start out talking about water. I brought oh, I brought my friend the the water bear to Hang out with us in this introduction because I love that guy that guy requires water to survive as do all of us as We learned in the last lecture. He can be Frozen down to almost absolute zero in that state. I'm sure he's pretty Dried out because otherwise, I don't know. I think he might pop But we're gonna learn about water and how all like we can't survive without it and The fact that water like water is weird. So yes, we're gonna have an entire section just on water Related to water we're gonna talk about solutions and how we calculate concentrations of different solutions and why that matters then a very important Discussion about pH and we're gonna do a little activity in the middle around pH that I'm kind of excited to see what you think of it and we're gonna wrap it up with a Section of little clip on each of the four big bio molecules That's the part probably where I feel like oh man, can we fit all our bio molecules in on top of a robust conversation about Solutions and water and pH and I think we can do it because all of those pieces tied up together Get us into get us ready for what we need to go into the cell Which is our next topic and that's where we finally are dealing with things that actually are alive Okay, so let's get started. Let's go see what kind of environment Let's learn about the environment Where our friend the water bear or moss piglet if you prefer lives
