Week 15- Balloon Blow Up

  

 Week 15- Balloon Blow Up

 Learning This Week:

This week during lab we designed our own investigation based on the NGSS PE 5-PS1-2 that discusses the change in weight in mass when a substance changes its state of matter. We were tasked to develop an activity for 5th grade students to perform to meet this PE. We designed the question, "why does a balloon inflate when mixing baking soda and vinegar?" We wanted students to perform two different experiments, one with mixing baking soda and vinegar in a bottle without a balloon and then one with a balloon. They would measure the initial weight, final weight, and then find a change in their results. We noticed a large change in the bottle that did not have a balloon and almost no change in the bottle with the balloon. This allows students to realize that the CO2 is being released from the baking soda and vinegar and that is what is causing the balloon to inflate.

Application to Future Teaching: 

This weeks learning allowed us to have the freedom to design whatever experiment we wanted to make the performance expectation we were given. I liked having the flexibility to work with my table group on designing an investigation on our own. We struggled initially with coming up with a question that would interest students, but once we figured that out the rest moved seamlessly. I think that this would be a good experiment to give to students at the 5th grade level to investigate changes in matter.

Questions for Further Study

1.) What other investigations could we perform to meet this same PE?

2.) Does distilled or white vinegar cause a different reaction than undistilled or rice vinegar?

    Hi Bailie! I really enjoyed your blog post this week! I also liked having the flexibility to do our our experiment and having the freedom to learn based on how we wanted to!

    Hi Bailie! I enjoyed your photos for your blog this week. My group and I did something similar but has to alter some parts due to some gases being released from our experiment. Great work!

    Hi Bailie!
    I really liked your explanation as to why when you put a balloon over the flask it inflates and the weight barely changes at all, but when you do not have the balloon over the container of the mixture carbon dioxide escapes and changes the weight. I also agree that this would be a good experiment for 5th-grade students and something that would be very engaging.

    Hey Bailie! I loved the way your group choose to create your learning activity. The balloon shows students a great observation of how the chemical reaction produces gas. Great work!

    I find it so interesting that you got the balloon so big! Even when we added more baking soda, our balloon seemed to be able the same size. Was there something that you did differently? What ratio of baking soda and vinegar did you use? Lovely work!

    Hey Bailie! Holy moly, look at that balloon go. Your group demonstrated the chemical reaction very well, and I agree that this is a great way to teach kids about the conservation of particle weight.

Week 10- Rock Cycle

      Week 10: Rock Cycle Learning in Lab : This week in lab we looked closer at what constitutes as a rock and how the three different rock types are created. We started with a formative assessment where we were given a list of items and had to determine if they were considered a rock, and why we thought that. After completing the assessment, we learned that a rock is naturally made, therefore items like a gravestone or marble statue are not considered rocks since they were make by humans. Limestone, cooled lava, and sediments are considered rocks because they are made through natural processes. We then experimented with the rock cycle by creating the three different types of rock, sedimentary, igneous, and metamorphic. Sedimentary is when materials are cemented and tightly packed together. We created this by cheese grating three different colors of starburst, then compacting them together into a little ball to represent the small minerals combined together. For our igne...

Week 6: Intro to Earth Science

    Week 6: Intro to Earth Science Initial Thoughts : 1. How do the phases of the moon occur? I think that the phases of the moon occur because the Earth is orbiting the sun constantly, as the Earth orbits it block part of the sun from shining on the moon. When the Earth covers more of the sun, then there is a smaller part of the moon showing at night, but when the Earth covers less of the sun or none at all, it is a full moon.  2. What causes the seasons? The sun is closer to either the Northern Hemisphere or the Southern Hemisphere. In the summer we are closer to the sun in the Northern Hemisphere so it is hotter, whereas in the winter we are further away from the sun so the weather is colder.  3. what causes a lunar eclipse?  I think a lunar eclipse is when the moon goes in front of the sun? Learning in Lab : This week during lab we did hands on discovery over each of these questions. We used a lightbulb, and two balls to see what position the Earth and moon ...

Week 8: Timeline of our Universe

Image
    Week 8: Timeline of Our Universe Learning in Lab : This week during lab we listened to six different presentations that cover the timeline of our universe. We started with the origin of the universe, which was my presentation, and we described that our universe was created at one single point called the Big Bang. During the Big Bang, Cosmic Microwave Background Radiation was left behind and protons and electrons combined to from hydrogen atoms. We understand today that space is continuously expanding. Then, we learned about the lifecycle of stars as they go from a nebula to a protostar, to the main sequence and transition into either a high mass or low mass star. Our sun is considered a low mass star. The more mass something has, the greater gravitational pull they have. Then, we learned about galaxies and how there are billions of galaxies out in space. Galaxies have several different shapes such as spiral, elliptical, and irregular. Our galaxy is spiral and our sun is pl...
