Physics resources for students: part 1

Good afternoon!

Today I’ll share a few of the resources  I use to teach the fundamentals of physics. One of the most fun aspects of teaching physics is that it lends itself to so many entertaining and engaging activities and demonstrations in class. Along with chemistry, physics is probably the most hands-on science I teach; therefore, real-world demonstrations and activities are the bread and butter of my physics units. However, there are any number of situations in which hands-on demonstrations aren’t possible or feasible: a lack of funding or resources at a school, broken equipment, abstract concepts or perhaps a student is simply reviewing material at home. In these cases, animations can provide a tremendous amount of help in understanding the essentials of physics. Most of the resources I’ve listed here are collections of animations to help students learn (and teachers teach!) about physics.

Explore and enjoy! Happy learning.

Ecology resources for students: Part 1

Good afternoon!

I’m back with another set of bookmarks for students and teachers. Because I’ve taught the IB Environmental systems and societies course for several years, this set of online resources is closest to my heart. Some of these links are here simply because I think they’re cool or fun. Many may also be applicable for studying biology and chemistry as well. Let’s get to it:

Happy learning!

Chemistry resources for students: Part 1

Hello again!

As with my last post, this one is dedicated to sharing the random assortment of helpful bookmarks I’ve collected over the years. Like the first part of my bio resources, these are in no particular order, unless you consider where they fall in my browser’s drop-down menu some kind of order. Without further ado, some resources for your chemistry studies:

  • PTable.com. Hands down the best periodic table on the internet. Period.
  • Chemistry.about.com. A good, all-around general chemistry resource. They’ve updated the site format to include news and events, which may tie in nicely with MYP Criterion D: Reflecting on the impacts of science.
  • LibreTexts virtual chemistry textbooks. These are some fairly advanced materials which may be more appropriate for students in Diploma Program or AP chemistry classes. Organized around broad topics such as analytical chemistry, environmental chemistry, organic chem, and physical and theoretical chemistry.
  • IB Chemistry Web. This site appears to be meticulously maintained, and it’s closely aligned with the new IB Chemistry syllabus. Heavy on text, but a tremendous amount of resources for every part of the course.
  • PCCL Flash animations for learning chemistry. These aren’t fancy animations, but they clearly and simply demonstrate a bunch of key topics in general chemistry.
  • Molecular Workbench. Hundreds of engaging, interactive simulations in chemistry (and other subjects). Many include embedded assessments, and you can build your own simulation if you really get into it. You can spend hours with the MW.
  • Cavalcade o’ Chemistry (a.k.a. ChemFiesta). Mr Guch’s incredible chemistry page. He’s been maintaining this page since the late 1990s, and it gets better and better each year. Supremely helpful for middle school and early high school students. He also has a special section just for teachers.
  • Practical chemistry activities from the Nuffield Foundation. Over 200 activities you can do to teach or learn about chemistry. Some are virtual, but many require a science lab.
  • Behind the Scenes at MIT. As the website tagline says, “A series of two-minute videos relating concepts from textbook chemistry to current MIT research and applications in medicine, the environment, and energy.” A nice way for students to see the real-world applications of what’s happening in the lab and the classroom.
  • Off the Shelf Chemistry. A series of 18 chemistry labs for middle school and high school. Download PDF or Word versions to use in your own class/lab.
  • Chemlab.com from Truman State University. This website hosts the course materials for several university-level chemistry courses, but many of them are appropriate and applicable for high school.
  • Periodic Videos from TED-Ed. “A lesson about every single element on the periodic table.” Enough said.

Those are my Chrome chemistry bookmarks. After I’ve run through my resources for earth science, ecology, and physics, I’ll revisit all these subjects and add a second round of resources from my Firefox browser.

Biology resources for students: Part 1

Good morning!

Over the past few weeks, I’ve been updating various pages within my website, and as I work, I keep encountering all these different websites and digital resources I’ve bookmarked over the years. My bookmarks bar is organized by broad scientific subjects: astronomy,biology, chemistry, ecology, and physics. I’ve also got a folder dedicated solely to scientific games. I will share the resources in these folders in subsequent posts, organized by subject area. Once posted in the blog, I’ll then add all bookmarks to the general science pages in my website, but I thought I’d take this opportunity to share them with the broader global community as well. I have so many of these resources that I’m going to have to split the list into two parts – the bookmarks from my Chrome browser and those from Firefox.

Today: biology resources for students (and teachers!) in no particular order.

  • The Cell: Basic Unit of Structure and Function by McGraw-Hill. Animations, quizzes, flashcards, and other resources aligned with their Human Anatomy textbook. Links to other chapters can be found in the sidebar.
  • Bioman Biology. Interactive biology games on a variety of topics, including physiology, cells, ecology, genetics, evolution, DNA, respiration, and photosynthesis.
  • Carbon cycle animation from the University of Alberta, Canada. A simple but comprehensive flow chart (system diagram) of the global carbon cycle.
  •  InstaGrok interactive concept maps. Pre-made concept maps showing links between a whole bunch of topics in general biology. Click on a term to see links to other biology topics, facts, websites, videos, images, or add your own notes.
  • Cells Alive! This site has been around for years. Good, easy-to-understand interactive cell models.
  •  DNA video from NotCot.org. A beautiful 3 minute animation explaining DNA for BBC Knowledge from Territory.
  • John Kimball’s online biology textbook. This guy has been teaching biology for decades, and he’s amassed an incredible amount of resources on his site around every conceivable topic in biology. It’s kind of an old-school site, but it’s thorough.
  • Learn.Genetics at the University of Utah, USA. I use the tutorials from this site extensively in my genetics and evolution units.
  • Bozeman Science biology playlist on YouTube. 76 videos! 76! This playlist contains videos that could be useful in AP Biology, IB Biology, Biology, and other life sciences, all from the amazing Paul Andersen.
  • Mitosis World Home at University of North Carolina, USA. An aggregate of several other biology resources.
  • Discover Biology animations from W.W. Norton & Co. High-quality animations that can be viewed straight through, step-by-step, or narrated.
  • Interactive transpiration animation from ScienceMag. Adjust plant parameters and environmental conditions to see different effects on the movement of water through plants. With some creativity, you could run a virtual lab from this animation.
  • Understanding Evolution at the University of California – Berkeley. Densely packed with information and thoroughly researched. I use this site as a main reference for my evolution units. The site has been around a long time and is showing its age, but it’s still highly useful.
  • Sex determination video at TED-Ed. One of many useful resources from the TED people. Includes a review quiz and discussion questions.
  • Biology for Life. A great website from Gretel von Bargen at Skyline High School in Washington state, USA. It follows the new IB Biology syllabus. Also linked to her Twitter feed. I use this site a ton.
  • Bioknowledgy. Probably my favorite site for IB Biology. Chris Paine in Shanghai has created an extensive library of resources and materials aligned with the new IB Biology syllabus. Includes presentations, videos, and guided revision questions, among other resources. Awesome!

I hope that’s a good start for now. If you find any helpful resources you think I’ve missed, please send them my way in the comments, and I’ll add them to the second batch.

Cheers!

Genius Hour is Back!

Good morning! It’s been a long time since I contributed anything to this blog apart from some tweet links, but I have good reason to return: My grade 10 students have finished the latest iteration of their Genius Hour projects. They  chose between biology and physics and were given 20% of all lessons to work on a topic of personal interest. Below, you will find a selection of some of the work I’ve received.

The Value of Experiential and Outdoor Education

Good afternoon.

I just returned to Dar es Salaam from our school’s Extended Studies Program (ESP) – a “week without walls” – in Amani Nature Reserve of the East Usambara Mountains of Tanzania. The 8th-grade students who accompanied me got to experience one of my favorite parts of this country, a location rich with endemic plant and reptile species, as well as a climate and geography radically different from the hot, steamy coastal zone where we live.

During our time in Amani, we encountered quite a few unique creatures and plants, including forest cobras, Fischer’s chameleon, the Usambara 3-horned chameleon, pygmy chameleons, black-and-white colobus monkeys, 20 species of African violets, army ants, the pregnancy-test frog (really!), tree frogs, colossus crickets, swallowtail butterflies, forest moths, damselflies and dragonflies, trumpeting hornbills, the African fever-tree, and a lot more tree species than I can possibly remember. We also studied craters on the moon and watched Jupiter and its 4 Galilean moons climb across the night sky while we were in camp.

Apart from my personal interest in biodiversity, mountains, astronomy, and forests, there is real value in taking students ‘out there’ to see and experience a part of the world they might not otherwise visit. These kids live fairly posh lifestyles here in Dar, and putting them in tents for a week really stretches some of them. They develop a greater appreciation for the ease and comfort of home, and they confront – briefly – firsthand the challenges of living off the land in tropical Africa.

They also get to do things we can’t do in a classroom: feel the way a chameleon grips your skin as it climbs up your arm, observe the dark bands in Jupiter’s atmosphere, try to decipher the code of flashing firefly lights in pitch darkness, listen to owls call across a primary forest, chase frogs as they try to escape into chilly ponds and streams, and feel the microclimate changes in light, temperature, and humidity between tropical forest and farmland. Adding these first-hand sensory inputs reinforces classroom lessons and clarifies what may be highly abstract concepts for a lot of students who spend most of their days indoors. Plus, they’re just plain fun most of the time (apart from the army ants).

Science History Rap Battles

Good morning.

Yesterday I posted a video made by one of my students about the sustainability of food resources because I thought it was a good example of what students can create when given creative latitude in the classroom. Then one of my fellow science teachers mentioned Tom McFadden, a science teacher who’s earned quite a YouTube following for his creative and engaging raps about science. Tom supports students creating science projects in other schools, and what he has enabled children to do is really quite impressive. He has a science blog here, and you can check out his YouTube channel here. I particularly like the science history rap battles. Here’s a particularly good one, which tells the story of Rosalind Franklin and the discovery of DNA’s double helix structure:

Sustainable Food Resources

My 8th grade classes developed independent projects focused on the role of plants in society, and I received a wide variety of products from them, from posters to presentations to animations. The one I’ve embedded below is a particularly solid example of the kind of work young people are capable of doing when given the freedom to choose a topic of interest and the resources to create something different.

Thanks for this, Abby!

“What if I don’t believe in the Big Bang?”

Good morning.

During one of today’s lessons, I received an email from a student asking the question above. As a science teacher, I’ve encountered this question before, usually when we study evolution, but my response applies equally to other fields of science – not just biology. I think it’s important to remind students and families about the key difference between the scientific and spiritual realms, and we will address the student’s question in my class later this week. I’ve pasted my response to this student below, with the student’s name changed for privacy reasons.

Hi Mr Kremer.

I was just wondering, what if you don’t really believe in the Big Bang? What if you believe in another theory?
Thank you
Curious Clinton, 8Z
That’s a good question Clinton, and for a lot of people it’s a tricky one. Part of the confusion is based on use of the word ‘believe’ instead of the more appropriate words ‘observe’ and ‘measure’.  Beliefs don’t need observable, measurable evidence. Observation means using only what we can directly sense and measure.

Science is based on observation and study of the natural world. We come up with ideas to try to explain what we can observe, and then we design ways to test those ideas – scientific experiments. If the idea fails the test, we reject it. If the idea is supported by the test, we build on it and go deeper, adding more detail so that we have a more complete picture of how the idea/process works. We keep doing this over and over again, and we have other people test the same ideas, until one of 2 things happens:

  1. the idea fails a test, and we reject it as being ‘not correct’
  2. the idea continues to be supported by observation, and we continue to build on it

So within science, it’s not really accurate to say that we ‘believe’ in an idea like the Big Bang Theory, or evolution by natural selection, or gravity. Rather, we accept the evidence that supports these theories. These theories have been tested many different ways by many different people and have always been supported by observation – what we can see, hear, smell, or sense. That means we consider them to be true up to the moment when one of them fails a fair test. If one of them fails a fair test and is disproved, scientists will no longer accept the theory as a valid explanation for how the world works.

One classic example is our understanding of the structure of our solar system. Before people developed the telescope, which allowed us to directly observe the other planets and their moons, the Geocentric model (Earth at the center of the solar system, with the Sun and the other planets orbiting around Earth) was accepted as scientific fact because it passed all the tests available at that time. But once we invented telescopes and were able to accurately see that moons orbit around other planets and those planets orbit around the Sun, we recognized that the ‘Geocentric’ model wasn’t correct – it failed the test of observation. So we developed a new idea called the Heliocentric model, which has proven correct everything we have been able to observe so far.

At some point in the future, when we have better technology that lets us make even more precise and accurate measurements and observations about our Universe, we may decide that the Big Bang Theory is wrong. When and if that happens, we will reject the BBT and start using a new, better explanation for how the Universe began.

Does that help? It was a really good question, and we will talk about it in class soon.

cheers

Mr K

I’ll close with one of my favorite quotes from Neil deGrasse Tyson on this topic: “One of the beautiful things about science is that it’s true whether you believe in it or not.”

iPads and Tablets in School

Hello.

It’s been a long time since I posted here. November’s been busy, busy, busy at school and at home. But I decided that I have something worth sharing today, and if you’re a student or a teacher, it should have a positive impact on the time you spend at school.

Last night I came across ipad4schools.org, another blog here on WordPress, which I’ve decided to follow because of the wealth of information I found there.

The post that really caught my attention is the one called “iPad guides“, which has some fantastic ideas on using iPads to engage students in their own learning at a depth I rarely see in schools. The post includes a number of PDFs, which you can print for a class or library bulletin board. They’re visually appealing and easy to understand, which means they’re likely to actually be used by the intended audience – students and teachers. I’ve already posted 3 of them in my room, and this afternoon’s last-period grade 10 class will begin experimenting with a few of them. This should be fun and educational!
