Today was all about DNA. We completed our first round of genetics notes as well as watched the video below about what is DNA and what does it do. Tomorrow we start NWEA testing, which we will finish Thursday. Friday we will continue exploring genetics.
In class today students took a short test over what we've done in class so far. Then we drew diagrams showing the levels of organization in an organism. Starting with the body of an organism going down to single alleles, this diagram shows increasing complexity in living creatures.
Today students graphed their paper airplane data and completed their lab questions. Tomorrow they will write their lab conclusion and begin their new unit, Genetics.
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.
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.
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!
We also watched a short clip of Dr. Neil deGrasse Tysontalking about why he thinks science is important then compared his ideas with our own.
