What should the results section include? The results is perhaps the most important part of the paper. In fact, when I was taught how to read a scientific paper, my professor encouraged me to start with the results and discussion. The results section should show the answer to the purpose and main question of the … Continue reading Science Fair: Writing your Results
The development of student use of graphs and tables is a skill that takes practice, and many students do not have the opportunity to carefully consider their appropriate use. January is the time in my class when students working on independent research projects are finalizing their data and preparing it for their papers and displays. … Continue reading Science Fair: Presenting Data
Its the time of year where my weekends start to be taken up with Science Fair. But as a teacher - its really nearly a year-round endeavor. Science Fair for me starts in May. May is when I find out what students signed up for my course for the following year, the students who I … Continue reading Mentoring Many Independent Research Projects – aka, “Doing Science Fair”
In the last decade, interactive notebooks have exploded in popularity. I tried them with my students, and I loved them. The majority of my students did not.Why?I was doing all the work. The students were still just talking notes or doing worksheet style activities. Just in this thing called an "interactive notebook". The students pointed … Continue reading Lab Notebooks: the grown up interactive notebook
This is the first year I don't have a "big" thing to do. The last few years have been overshadowed by earning a degree, completing Ohio's RESA (I passed!) and just getting used to being a working mom. That's why I've been a little absent from my blog. Tomorrow is the start of my school … Continue reading The start of the school year. But not really.
Scientists solve problems as a community - science fair projects should not be done by students in isolation.
It's a simple question: what is the relationship between mass and volume?DensitySome students immeadiately said, "Density!" So, I asked them to describe density in terms of particles, and they couldn't.There was a whole day of collecting data. A bunch of plastic blocks, mass on a triple-beam balance and cubic centimeters. Aha! As the volume increases, … Continue reading Density, proportional reasoning, and misconceptions
Activity to investigate the relationship between cubic centimeters and milliliters. Students carefully (or not so carefully) calculate the base area for their container, fill it to various heights (depths) of water, and measure the volume of water in the container. One group of students recalled a prior teacher told them that one centimeter cubed equalled … Continue reading Modeling and volume, with precision and accuracy
A brief story about teacher evaluations I am in the state of Ohio, so some of this is about to be a little Ohio-centric, because its what I know. The purpose of evaluations of teachers in the state of Ohio is: To improve instruction by facilitating professional growth and development To identify needs for staff … Continue reading Teacher Evaluations – and what you can do for teachers you care about
As a graduate student, I was assigned the TA job for an introductory course in geology. I really like physical geology - its the course where you get to look at all sorts of rocks and minerals, learn about specific gravity (a favorite of mine) and other physical characteristics, and maybe some introductory geology. Sounds … Continue reading Course Design – The value of online lab course materials (college version)
