Traveling Otters

 Welcome to a new post. This is for Unit 2 of the STEAM class Population. This class focused on adaptation and evolution. We discussed how animals have adapted over time to be better suited for their environment. We talked about mutations and watched a video of bacteria traveling through antibiotic by developing mutations to pass through them. In this class the central tendencies in math became important and was used more frequently up to the Action Project. Like in the last unit there was another dissection. This time we dissected an owl pellet or owl regurgitation. In my dissection I found three skulls of what looked like rodents and some other bones as well. This dissection did not smell as bad as the worm. For the AP I chose to look at the North American river otter. With these amazing mammals I tried to predict what they would be like in at least 500 years and made a data set from ten river otters. One important aspect from this AP is our group of animals being transported to a different environment they are used to. So the ten river otters I thought looked up for the challenge went on a virtual trip to the El Yunque rainforest in Puerto Rico. The slideshow consists of everything required in the AP and enjoy. 



I hope you liked the slideshow I created talking about the river otters. We did go over some of this in class such as who is most or least likely to survive and I changed a couple after looking at it a second time. Doing this in class was very fun because we were all together and made it into a small story that played out in front of us. I think all otters are pretty amazing creatures. Their abilities like closing their noses and ears when underwater are really crazy and the movement is interesting given the long body. I can't remember what animal I was going to observe more before the otter but it might have been ferrets. This AP was cool to work on even if we had a shorter amount of time than usual. This is the end of the Fall term so we were trying to get everything that needed to be done fast to get started on the AP. We still made it work though and this class was great and even better with our very fun and cool teacher. Thank you for looking at this post I hope to see you in the next term.

Diddley Bows: One-stringed guitars

Welcome back to my blog. This post is for the second Action Project of the STEAM class: Light, Sound, and Time. This unit, sound, was all about how sound is made and what happens for humans or animals to perceive it. Sound travels as a longitudinal wave and is explained as vibrations coming from a source that we perceive to be sound. To start, we examined how the human ear worked and our range of audible frequencies compared to infrasound and ultrasound which humans can’t hear. We then looked at the speed of sound and how it changes based on the medium it travels through. Following the understanding of how sound travels, we investigated traveling faster than the speed of sound or breaking the sound barrier and also the Doppler Effect. Lastly, we looked at stringed instruments like guitars and found how they make sounds. We also had one Field Experience at Guitar Center to look at the guitars and other instruments there. For this Action Project, the task is to create a diddley bow which...

What is your Carbon Footprint?

This is the last Action Project of the Fuel class for STEAM. This unit focused on chemical reactions, carbon emissions, and inequalities. This unit was very short compared to the other two but still enough time to learn everything we needed to get to. When working on the chemical reactions we talked about how certain molecules reacted to from something else. The main molecules we worked with were oxygen (O2), carbon dioxide (CO2), and water (H2O). Since the unit was only a couple weeks long there was not much time for Field Experiences so the only one that we had was going to a water cooling facility in downtown Chicago. Here we learned about how this plant cools down water for nearby buildings by using ice. I thought this FE was really cool and it was interesting to hear about the projects that they did and how they got them done. A lot of their work when connecting their water to the buildings involves large pipes underground which can be a difficulty when in a busy city. One of thei...

The Drinking Bird Clock

Welcome back to my blog. This post is for the third Action Project of the STEAM class Light, Sound, and Time. This unit, Time, has been all about how we perceive time and what it actually is. We first questioned when time originated and why we believe time began directly after the Big Bang. Then, we looked at older methods of telling time such as using the position of the sun for a sundial. We also looked at longitude and latitude and how we determine our position because of it. For determining latitude, you can use the North Star if you are in the Northern Hemisphere or a sextant which is a device that uses mirrors to find the angle of the sun to the horizon. For determining longitude, you can use time zones and Greenwich Mean Time (GMT). To continue our examination of time-telling devices, we spent time studying pendulums and the Foucault pendulum which is a pendulum that can rotate 360 degrees and show how the Earth will rotate beneath it if it were at the North Pole. For Field Expe...
