Absolute Zero - Nova

I have found the Nova Absolute Value video an good suplement for my Thermodynamics Unit. Students really enjoy listening to the lives of the scientists involved in these experiments. After watching segments of the video I use the following follow up questions.

Conquest of Cold

Video Notes - Keep track of European and American Advancements in Cold Technology.

Assignment

1. Compare and Contrast the European Cold Advancements to the American Cold Advancements.


2. How has your life been impacted by the cold advancements? Pick one of the inventions talked about today.

Race to Absolute to Zero

Video Notes - Keep track of Dewer and Onnes

Assignment

1. Describe the set up of their experiments and how it worked to reach colder and colder temperatures.


2. Write a poem describe the race to absolute zero.


3. What does it mean to be “in a race with the goal post constantly moving?” Describe a time when you have experienced this in your own life.

I have students offer unique and thoughtful answers to these assignments. I am impressed by my students creativity and you may be too. I often give students a choice of assignments and do not assign all of the them.

Literature Review - Transformative Assessments

Transformative Assessments by W.J Popham did a wonderful job setting up what formative assessments are and why they are beneficial to the classroom. Popham says (2008) “Formative assessments is a planned process in which assessment elicited evidence of students' status is used by teachers to adjust their ongoing instructional procedures or by students to adjust their current learning tactics." (Popham, p.6) Popham insists on the idea that the formative assessment is a process meaning a way of making informed decisions about instructional procedures not just for the following year but for the current teaching moment. Popham describes formative assessments in four levels to help distinguish the different uses of formative assessments:
Level 1: Teacher use of formative assessments for use in instructional activities
Level 2: Student use of formative assessments for assessing their own learning
Level 3: Change in classroom environment with regards to classroom assessment
Level 4: School-wide adoption of formative assessments at any of the other levels
For the purpose of my research I am currently looking at Level 1 formative assessments to make a change in how I design and use formative assessments in my classroom to inform my decisions. Within this level there are four steps according to Popham: Step 1 is to "identify assessment occasions"; step 2 is to "select assessment procedures"; step 3 says “establishes adjustment triggers”; and step 4 is “makes instructional adjustments." I would like to move along in the levels but feel like I need to make one step at a time and these four steps of level 1 are enough for me to concentrate on at this time.
A favorite quote of mine from the transformative assessment was (2008) "Don't let pursuit of the instructionally perfect prevent you from reaping the rewards of the instructionally possible." (Popham, p. ix) While I feel like I have not even scratched the surface of what can be learned from formative assessment it is important to keep trying and learning to make my classroom a better learning environment.

Science Formative Assessment - Paige Keeley

Page Keeley in her book Science Formative Assessments had many ideas about the benefits of well thought-out formative assessment plans in the classroom. Keeley stresses the importance of understanding student’s knowledge and beliefs before a lesson to help students make connections to prior knowledge. Without connecting a lesson to prior knowledge the information will not stick in student’s brains beyond the unit says Keeley. Keeley says (2008), " Optimal opportunities to learn exist when science teachers are aware of the variety of different ideas students are likely to bring to their learning, see the connections between students' thinking and specific ideas targeted by state and national standards." (Keeley, p. ix)
Keeley's ideas help the teacher not only assess what the students know but ask the students to explain what they know or how they arrived at the answer. Keeley says, “the formative assessment techniques included in this book initiate the use of metacognitive skills and promote deeper student learning." (Keeley, p.5) Thus Keeley's FACTs (Formative Assessment Classroom Techniques) helps students recognize how they think about an idea and make the decision. Keeley accomplishes this deeper student thinking by asking "probing questions" that ask students to make a choice and then explain their choice or their "rule" for thinking.
The majority of Keeley's book discusses 75 practical strategies that can be used in the classroom to help promote learning as well as give the teacher formative assessment data. Keeley describes the process as " Students are learning while at the same time the teacher is gathering valuable information about their thinking that will inform instruction and provide feedback to students about their learning." (Keeley, p.3)

Conservation of Energy

Recently in Kentucky an ice storm hit closing the schools for at least a week. During this time I had time to spend with my niece and nephews sledding down the ice covered hill. We had a lot of fun but all the while I was thinking... this would be a great illustration for the conservation of energy. So my sister and I got out the video camera and we created the following video. Enjoy!

Monkey Hunter Problem and Video Hooks.

Microsoft Movie Maker

During this problem students have to predict whether the monkey or the banana was shot with the tranquilizer dot. This problem is an example in our Holt Physics textbook, however, I used the video to hook my student's interest into the problem.

To create the video I used my digital camera, a clip from discovery, and Microsoft movie maker software. This software is user friendly and does help engage the students into a lesson.

The video can be made into a DVD using a DVD writer or shown on the computer.

Chemical Bonding

Currently in Introduction to Chemistry and Physics we are studying Chemical Bonding.
We have finished day 1 objectives. This class is designed for the non-college bound students. It is a survey of Chemistry and Physics. We have studied Matter, Atoms, and the Periodic Table.


Unit Objectives
Day 1 -2. Construct and/or interpret diagrams that illustrate ionic and covalent bonding.
Day 2 -3. Predict compound formation and bond type as either ionic or covalent
Day 4. Represent the products formed with simple chemical formulas.
Day 5 - 6. Identify and test variables that affect reaction rates.
Day 7 -8. Use evidence/data from chemical reactions to predict the effect of changes in variables.
Day 9-10. Relate the chemical behavior of an element, including bonding, to its location on the periodic table.
Day 11-12. Explain the role of intermolecular or intramolecular interactions on physical properties.

Lesson Ideas:

Day 1 : Fruity Pebble Lewis Diagrams - use fruity pebbles as the electrons for metals to show the electron transfer from metals to non metals in ionic bonds.

Calling all Science Teachers!

Hello!

I am a Physics teacher in my third year of teaching High School. The purpose of this blog is to set up a place for Science teachers to communicate ideas for lessons, labs, and for the classroom. Collaboration brings about the best results for all involved. If you have any suggestions, ideas, or questions please feel free to post here.
