Week 5: Source of Living Things

 


Week 5: Where Does Living Stuff Come From 


What question are we investigating?

This week we investigated the questions, "Where does living stuff come from? Where does it go?". 

What did we do in lab to investigate this question?

To begin, we started out with a whole class discussion while reviewing the ways seeds can travel and spread.  We then watched a few videos and created a class list of different ways seeds are dispersed throughout the world. Next, we went over the procedure for the activity that we were about to complete. Each group picked one of the methods of which a seed can be dispersed throughout the land. After choosing a method, each group had to prepare a physical presentation to emulate the seed dispersal. Our group chose the method of seed dispersal traveling through animals, particularly birds. We created a replication of a bird, picked up a seed through the beak to represent the bird eating the seed. We then moved to a different part of the room and dropped the seed out of the bottom of the bird to represent the bird pooping it out. 


What did we figure out?

We found out that there are several different ways seeds can be dispersed all throughout the land. Seeds can be dispersed through fires, fur from animals, being eaten by other animals such as birds, the wind, seed explosion, water and more. We learned that some plants explode and there seeds fly all over spreading them. We also figured out that fire can germinate plants and continue there growth and seed dispersal. Water and wind also play a big part, water can flood and move seeds to different locations, while the strength of the wind can blow seeds to other locations. Birds and other animals can eat, or catch seeds onto their fur and spread them miles away from the source of the plant. 


What are new or remaining question after the investigation? 

I was wondering how fire does not burn the seeds of the plants to ash, is it because the roots are still in the ground so they regrow into new plants?

  Week 4 Blog: Monarch Butterflies  What question are we investigating? This week we investigated Monarch butterflies, as well as what makes a question "good" according to the NGSS. Our class had several questions about Monarch butterflies such as, how do Monarch butterflies know where to travel, how does the super generation reproduce, and how do they travel so far.  What did we do in lab to investigate this question? We used the acronym KEWL to begin setting up our investigation. Starting with what we know, our evidence, what we want to know, and lastly what we learned. There were 5 different stations set up in the classroom to help us investigate these questions. The first was different diagrams of the butterflies life cycle, the second was parts of real Monarchs under a microscope, the third was looking at the caterpillars, the forth was analyzing the chrysalis, and lastly watching a video of the growing process and looking at learning materials.  Chrysalis Cater...

Week 13: Testing M&M's

 Week 13: Testing M&M's What are we investigating? What is fundamental? Why the colors mix?  Does the color affect the speed of the dye? How did we investigate this? This week we continued to investigate different things and learn how to use particle models of matter in order to explain phenomena. In learning how to use particle models of matter to explain different phenomena we also learned the importance of using models to help students understand concepts, and also pushing them to create their own models. When investigating the questions we had in lab we conducted several different experiments as a class. This experiment rather than being done in small groups was done as a whole class to begin with. Each table got a different color of M&M that they would be conducting the experiment on. Each student got a plate with water in it. As a class we were investigating the question of does the color affect the speed of the dye. The professor told us all when to drop the M...

Week 12: Properties of Matter

 Week 12 Properties of Matter What are we investigating?  How do properties change when objects are broken into pieces? What we did to investigate this? In this lab we explored the properties of matter, we did this by discussing what we noticed about some of the observable physical properties of these objects. We made a list on our white board that included mass, density, malleability, hardness, conductivity, and more. We had ten different objects such as crayons, wood, straws, foil, paperclips, corks, and more. Use materials such as graduated cylinders, a light bulb, and a scale we tested all of our different objects to figure out what was on our list. Each object had a small size and a big size of it that way our tests were more extensive.  We found out many things some of the data was affected by the size of the object, but others were not. We also found out which objects conducted electricity, which were dense, which was malleable, and many more. Majority of our predi...
