Paper Airplane Conclusion

8/31/2018

0 Comments

 
Picture
In class today we wrote our conclusions for the paper airplane lab. We also added our class graph to our notebooks.




These are the prompts for writing a complete conclusion:
​
  1. Address your hypothesis; what happened in the lab and did that match what you thought would happen or was your hypothesis wrong?
  2. Explain your results. Report the key pieces of data that tell us what happened.
  3. Interpret your data: Answer the scientific question based on your data
  4. Discussion: What did we learn in this lab, how could we do it differently to get better data, what other experiments could we do to continue to expand on this experiment


We ended class starting our new unit Genetics, which we will dive into fully on Tuesday.
Gold Tape Question: Who is the "Father of Genetics" and what did he study to determine the "laws of inheritance"
You must email your response to spencer.powell@d51schools.org before school starts Tuesday to earn this week's gold tape.

Paper Airplane Data Analysis

8/30/2018

Use the video below to help you make a line graph of your paper airplane data. You should graph all of your data points (do not graph the averages for this graph). Your graph should have three lines, one for each type of paper airplane. Make the X axis the "Trial Number" and the Y axis the distance.

Good luck to all students on their beginning of year NWEA test. We will take this test again at the end of the year to see how much science we've learned and how much we've improved.

Time for me to fly!

Students flew their paper airplanes today and collected distance and time data for each type of airplane for a total of four or five trials. Tuesday and Wednesday next week we are in the computer lab for NWEA testing. We will finish our lab on Thursday.

GOLD TAPE QUESTION: Every week for the rest of the year we will have a "Gold Tape Question" Students that answer the question by the next class period will earn a piece of gold tape for their notebook. Who ever has the most gold tape on their notebook at the end of the year will be honored as the Scientist of the Year! This week's question is simple. Email Mr. Powell spencer.powell@d51schools.org or send a comment through this website and explain the best part of 8th grade so far. In addition to a piece of gold tape, this weeks winners will also get a donut on Tuesday. Go for it!

Paper Airplanedemonium!

Today students began their first lab of the year. In this lab students make three different paper airplanes. Although the planes are the same size and style, they are made of three different materials; construction paper, printer paper, and notebook paper. The three different materials are all different masses which allows students to test the scientific question, "Does the mass of a paper airplane affect how far it flies?" Tomorrow we will test our planes and analyze our results. The lab sheet for this activity is attached below.

Why is Science Important?

8/22/2018

0 Comments

 
As we wrap up our beginning of the year introduction activities, the last question we pondered is "Why is science important?" After discussing our own thoughts, we watched a short clip of Dr. Neil deGrasse Tyson talking about why he thinks science is important then compared his ideas with our own. We ended class starting our first lab of the year Paper Airplanedemonium. Tomorrow we will continue our lab which we will finish on Friday.

What is Science?

8/21/2018

0 Comments

 
Today we thought about and discussed the question "What is Science?" By working individually, in small groups, and as a class, we identified a lot of things that have to do with science like experiments, chemicals, biology, and lab coats. We also watched a short clip of Dr. Richard Feynman's lecture about the scientific method and from his description created our own definition for what science is. 
Science is making a guess about the universe, testing (experimenting) that guess, then comparing the results of that test (experiment) with our original guess to see whether it holds true or not. ​

Today in class we continued setting up our lab notebooks. We tape "Plicker" cards to the backs and created a pocket in the front for our daily assignment pages. We also "Cut and Glued" our Table of contents to the first page of the notebook.

What does a scientist look like?

8/16/2018

0 Comments

 
,In class today we drew what we think a scientist looks like. And although there were a lot of safety goggles, lab coats and bubbling beakers, there were also men and women of all shapes and sizes. Science is for everyone and anyone can be a scientist. Historically a field dominated by men, science is becoming more and more inclusive everyday and in fact kids are starting to catch on. According to this sciencemag.org article, children are now drawing scientists as women at a much higher rate than  previous decades and this parallels an increase in women in the science field. Throughout this year we will study many different scientists, men and women, young and old, American, Mexican, European, Asian, African, Indegenous and more. Check out the video below about video game designer and computer scientist Lizette Titre-Montgomery as she explains how she went from being a cartoon animator to designer video games!
