Week 12

 4/17/2025


This week we talked about how properties change when objects are broken into pieces. We got to explore properties for the whole object and compare them to properties for a piece of the object. My group got to look into the properties of wood balls, paper clips, candle wax, crayons, chalk, pennies, erasers, and aluminum foil. My group found it interesting that our large piece of aluminum foil floated at first and then sank when turned to the side. It was interesting that at a different angle the material will float or sink. 

I understood why most of the objects sunk or floated, could conduct electricity or not, have the same mass, and attract a magnet or not. The property that confused me was figuring out whether the objects had the same or different volume. Our objects repeatedly got stuck in the graduated cylinder so we were not able to actually see if the volume changed. 

The experiments that we conducted in class today are all easily transferable to the elementary classroom. It would be interesting for students to collect objects from around the classroom to do this experiment like the materials we did the experiment with. Then children are doing the experiment with familiar everyday objects. By performing this experiment it makes understanding the various properties of objects easier by having a visual to pair with it!

  2/26/2025 This week in the lab I got to look into a specific biome and understand the depths of it. Our group's chosen biome was a grassland. I knew that grasslands were mostly open areas that mostly had the ideal environment for growing grass. I learned that these areas get low rainfall amounts, just enough to allow the grass to grow, not necessarily trees. There were also a large amount of animals I didn’t realize lived in the biome like raccoons and capaparas. Another thing I learned today is that you can pollinate flowers with dead bees. We used the dead bees to pollinate our fast growing flowers. In the end portion of class we talked about the amount of baby turtles that don’t make it to adulthood. I have in the past done many projects on sea turtles and their survival rates. I was aware of the many factors humans can assist with that go into turtles survival like turning off porch lights and disposing of garbage correctly. Both of these help turtles in ways to use the moonl...

5/8/2025 This week I clarified a lot of the experiments that we have investigated through the last five weeks of the semester. I connected that when a plunger is stuck to a table the particles on the outside are pushing down on the plunger. Another connection I made was when doing the balloon, baking soda, and vinegar experiment we are surrounded by air. When the balloon blows up it pushes air out of the way. When you blow up a balloon in air you are pushing air out of the way. This is called buoyancy.  It was a little confusing or maybe just mind boggling that when we shook the vinegar and baking soda a gas was produced, but the weight did not change. At the closure of lab it was made clear that there is a gas that was produced that was not there before and it doesn't affect the weight.  All the experiments that Dr. Nordine has introduced to me and assisted in conducting can be done in my future classroom. I have learned that explaining the WHY to kids is important and as an ...

4/4/2025 This week I did not necessarily learn anything super new in lab. We did an overview of information and activities that reflected on our learning from the past weeks because of the cumulative exam we took this week. Our in class activity this week incorporated natural selection and evaluation. The activity showed how evaluation is more favorable towards some traits and how it becomes more favorable in organisms over time.  The overall concept of evaluation makes sense to me, but the activity confused me. It was not clear to me that the utensils each individual in a group were given were the specific traits. After each round the utensil (organism) that picked up the least amount of beans got to pick a different utensil. I did not fully grasp the general concept of this until after the game. Looking back I now understand that natural selection is a driver for evolution because the favorable traits in an organism lead to the traits that are more commonly seen in a population....
