The summary that I have came to the myth that you all may have heard of, Caffeine dehydrates you is false. That caffeine that you put into you body does not actually dehydrate you at all, most of the drinks that you put caffeine such as dark coffee which is 95% water. Reading up on this myth says that people think that I may dry out skin and causes headaches. I found a study that used 50 male coffee drinkers who consume around 3-6 cups of coffee a day and the study lasted 3 days so they could measure there process, each day they would measure the total water mass and there plasma which analysed the caffeine confirm compliance. At the end of the texting there was no significant change in the total water mass in all 40 of the males. Drinking a significant amount of caffeine could lead to a small diuretic effect but this effect is not strong enough to counter balance the intake of the water since your body is made up of about 60% water. The study shows that actually say that is good to have a cup of coffee before a run or a work out, one so you can get more energy and two because you are still intaking water. So to come to my conclusion the myth on that caffeine dehydrates you is busted and the result is that Caffeine is fine for the water level of your body and in moderation and can help wake yo up in the morning without you having to worry about your water intake balance.
I have chosen to reflect on the mom’s apple pie jam. I chose the jam since it was all new to me on how to make and seal the jam, and that there were a lot of difficulties along the way. I really enjoyed this lab because I had a really fun group and I feel like the whole class started to talk and laugh together which was fun. The jam turned out really well which I was happy about since at the beginning I was unsure about how it was going to turn out because I forgot to peel he apple before I cut them and so I realized that I needed to still peel them when they were chopped up. My group also was unsure if the snap tops were going to snap down at all. But everything went well and the jam tasted really good. My group was really fun and really supportive when I messed up a bit, the only problem that our group had was that we would switch our tasks which kind of worked but I think for next time to just keep our tasks the same through out the making of the jam.
How did the discovery of DNA prove that Darwin’s theory of evolution was correct and how does it change the way we view evolution today and into the future?
Charles Darwin’s theory of evolution has been prove correct by looking at DNA from different animals and sees in similarities in the code of the genes. Looking at human DNA to Chimps DNA there is only a 1% difference in our DNA, but clearly we look and act different. Through looking at the genes Michael Nackman from the university of Arizona noticed that from the Pincate desert, pocket mice evolved to blend into the volcanic rock. The mice that had a mutation would have fur that went from white to black, which would let the evolved mice better off surviving where the volcanic rock was since it could blend in more easier.
For today and the future of how we see the evolution, it shows us proof that we are evolved creatures from other creatures most likely coming from fish at the beginning all makes more sense. In the video “What Darwin Never Knew” they mentioned that fish embryo and human embryo have similar features in where you can see gill like cuts near the neck, where in fish they turn into gills but in humans they disappear.
What I learnt: Pyrolysis is where a chemical change makes the coffee bean more flavorful and darker the coffee bean it has less caffeine
What I knew already: Grinding your own coffee and making it yourself makes it taste better
Questions I have: how long does it take to grow a coffee bean? Answer: It takes about 3-4 years for a newly planted coffee bean tree to grow
In my home my family and I compost as much as possible, we use the city compost for most of our food waste and we also use compost in my backyard where we make our own soil to but in our garden. When we are out of the house if there is no compost bins it can be quite hard to limit waste. At school if I see a compost bin I put most of my food waste in it but if it is not convenient for me I just toss it in the garbage.
The area that I can improve on with limiting my food waste would be… at school to not use convenience as an excuse and either go and find a compost bin or put it in a container that I had at lunch and bring it home and put it in the home compost. At home I think it would be a good idea to limit the amount of food that we put in the compost by eating left overs more and not buying big balks of food that we wont eat.
The actions that I am going to take to limit my waste will be to eat more left overs so we dont have to waste as much good food. I also want to make sure that when I am out of my house to use the community compost bins and there is not to bring it home and compost it in my home.
