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:
- United States Census Bureau. Extensive database of global human populations. Can be used to create age-sex pyramids, as well as other applications.
- Earth wind map. A cool interactive resource to check wind patterns in real time anywhere on the planet.
- Visualizing Environmental Science, 1st edition. By John Wiley and Sons, Inc. Online textbook and animations. Much of the site is password protected, but parts are available for free.
- IB Environmental systems and societies worksheets and past questions. From Pearson, a of publisher of one of the IB-aligned student textbooks.
- Edge of Existence, by the London Zoological Society. Full of resources on endangered species.

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.

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.

Today is the second day of the 2016-2017 school year, and for the first time since early in George W. Bush’s administration, I’m not in a classroom. I have self-identified as a teacher for so long that I’m not entirely sure what to think of this situation. Part of me feels like I’m still on my summer holiday, and part of me feels relief that I won’t be grading papers and sitting through meetings after a long day of lessons, duties, and after-school activities.
There’s a new baby in my family, and my partner works long hours at her job. With two other children on two different campuses, our daily lives were already hectic enough, so we decided that I would take some time off to be with our wonderful son Aaron. After all, he’ll only be a baby once! When he’s old enough for preschool, I intend to go back to teaching full time. I love what I do professionally, but my family is my highest priority. Besides, who could resist this cute guy?
I’m still fascinated by all things scientific, and I can’t help but follow the latest developments in biology, astronomy, and environmental science. With that in mind, I plan to spend a portion of my time away from school enhancing my professional ‘bag of tricks’ and honing my social media skills in order to be a better teacher when I do return to the classroom. My focus for this academic year will be tweeting relevant science news articles, developing more student-centered activities and units of study, and, hopefully, earning a certification in Google Apps for Education. I’ll continue to write about science and teaching resources in this blog, but you’re more likely to see me active on Twitter (@bradleymkremer).
Good luck this year!
I’ve been in Tanzania for 8 years, long enough to get a feel for the seasons here juse south of the equator. In most years I expect a few weeks of rain in October or November, wit’s a more substantial rainy season from February through late May or early June.
2016 has been a little different. The short rains of October/November 2015 didn’t seem to fully materialize in Dar es Salaam, with only a few showers scattered here and there. The “long rains” didn’t hit Dar until April, a month later than normal, and when they did arrive, they were intense but short-lived.
Why do I bring this up? This year’s rains exemplify a few important points to understand about science.
First, the intersection of a wildly complex system such as the global climate, with literally thousands of inputs (variables), and a separate-but-related phenomenon such as El Niño produces patterns which we don’t yet fully understand. These patterns require further study, which brings me to my second point.
The tendency of some people to attribute an odd rainy season, intense storm, or other singular event to one overlying cause is a profound misunderstanding of how science works. Repetition is critically important to understanding the underlying interactions between variables, whether in a controlled lab experiment or an open ecosystem. That’s why climate-change-deniers are wrong to seize upon a big snowfall as evidence of no glocal warming. It’s also why those who point to one particular heat wave or drought as proof of climate change are equally wrong.
Let me be clear: there is an overwhelming consensus based on reliable evidence from thousands of repeated observations that our planet is warming as a result of human activities. I’m not denying that scientific consensus. I’m simply describing the danger of basking conclusions on non-scientific thinking.
Enjoy your summer holiday!

I’m back in Dar after another incredible week at the Emau Hill camp in Amani Nature Reserve, where I got to spend several days hiking in tropical forests, chasing chameleons and tree frogs at night, and exploring the tea estates surrounding the forest reserve.
I owe a big thanks to Roy Hinde and his staff at Wild Things Safaris for their support, extensive knowledge of the local ecosystem, and fine cooking.
This ESP trip is one of my favorites because of its location. The Usambara Mountains are still my favorite part of Tanzania, even after 7 years in this country. I’ve traveled there six different times, and I look forward to going back again because there’s always more to explore and something new to do.
Amani is one of the best places for birding in East Africa. Over 400 species have been recorded within the reserve, owing to its habitat diversity: tropical montane forest, miombo woodland, river valleys, and agricultural fields. During this trip, I spotted 14 bird species new to me, bringing the total number of bird species I have encountered in Tanzania to over 150. Unfortunately, I don’t have a fancy camera with a telephoto lens, which means I don’t have any photos of these new species, but here are my latest observations:

- Uluguru violet-backed sunbird, Anthreptes neglectus
- Trumpeter hornbill, Bycanistes bucinator
- White-tailed crested-flycatcher, Trochocercus albonotatus
- Augur buzzard, Buteo augur
- African palm swift, Cypsiurus parvus
- Lanner falcon, Falco biarmicus
- Waller’s startling, Onychognathus walleri
- Yellow-bellied waxbill, Estrilda quartinia
- Pin-tailed whydah, Vidua macroura
- Striped kingfisher, Halcyon chelicuti
- Yellow wagtail, Motacilla flava ‘superciliaris’
- Mountain buzzard, Buteo oreophilus
- Red-rumped swallow, Hirundo daurica
- Martial eagle, Polemaetus bellicosus
All in all, despite averaging over 15 km a day of strenuous walking and hiking, I came back from the trip refreshed and energized because of the chance to get out of the city for a week. If you have the chance to visit the East Usambara Mountains, please do – you won’t regret it.
We are rapidly approaching one of my favorite things about my job: the Extended Studies Program, or ESP. ESP is our school’s “week without walls,” when students and teachers leave the comforts of classrooms and campus and travel to different parts of Tanzania to learn about and experience the people and ecology in those locations.
Each year, students in grades 6 through 11 spend a week in one of an awesomely diverse locations around Tanzania:
- 6th graders go to Zanzibar for an exploration of art and architecture, reef and mangrove ecology, and a history of the east African slave trade.
- 7th graders spend a week in the Uluguru Mountains on a service learning trip with the Waluguru, the only matrilineal ethnic group in Tanzania.
- 8th graders venture to Amani Nature Reserve, where they experience the differences between managed and natural forests, as well as night hikes searching for rare species of chameleons and frogs (my personal favorite).
- 9th and 10th graders have several options for their ESP trips:
- Mountain biking in the Usambara Mountains
- Service trips in Arusha or in a Maasai boma
- Hiking in Lushoto district
- Trekking across the Ngorogoro Crater Highlands
- Ecological monitoring at the Makatube Island Marine Reserve
- Service work on the Chem-Chem school project
- Morogoro photography
- IB1 students in grade 11 engage in a field course for biology and geography
In my opinion, these kinds of trips provide the most engaging educational experiences our students will get during the school year. There are no worksheets, no essays, no problems to solve, no presentations to make. Students push themselves, and teachers push them, in ways that are generally not possible during lessons. The interconnectedness of different fields of study becomes evident while out of the classroom – the impact of climate on agriculture, which in turn influences economics, culture and family structure, which then have further knock-on effects on music, literature, and politics.
ESPs are wonderful because of their ‘big picture-ness’.
