Science Apps for Your Smartphone

I just stumbled across this Slideshare presentation by Stephen Taylor, and I think it’s a fantastic resource. He’s done all the research and written succinct explanations, so I won’t try to improve upon his work. There’s something in here for students and teachers of almost every discipline.

Thank you Mr Taylor!

Happy Holidays!

Today is the last day of the term for my children and for many of my teaching colleagues and friends around the world. In honor of all the hard work this year, I simply wish to share with you two videos. The first is, in my opinion, one of the all-time-classic Christmas songs. The second is brand-new, and I think I listened to it 4 or 5 times in a row last night.

Have a great break everyone!


Chemistry resources for students: part 2


Today I’m sharing a collection of chemistry bookmarks, which I hope students and teachers of science may find useful.  Some of them are specific to a particular unit of study, while others are more general in nature. There are definitely some duplicates here from my previous posts, so I apologize for the extraneous material, but it’s still good stuff. Today’s post focuses on general chemistry. You can find additional bookmarks in my earlier post, “Chemistry resources for students: part 1.

That’s all for now, folks.

Happy learning!


Biology resources for students: part 2

Good morning!

It’s time for more science bookmarks! This morning I’ll be sharing a collection of bookmarks, which I think students and teachers of science may find useful.  Some of them are specific to a particular unit of study, while others are more general in nature. There are definitely some duplicates here from my previous posts, but I don’t think there’s much harm in that. I’ve categorized all these resources by subject: astronomy, biology, chemistry, ecology, and physics. Today’s post focuses on general biology. You can find additional bookmarks in my earlier post, “Biology resources for students: part 1.”

I hope these aren’t too repetitive. I just want to pass them along so that my students and colleagues have access to some of the many wonderful biology resources I’ve found over the years.

Happy learning!

Elections get in the way of science news

Good evening!

In addition to the professional presence I have on Twitter (@bradleymkremer) and here on my science blog/website, I have a personal profile on Facebook, which I think doesn’t make me unusual in any way. I usually make a fairly concerted effort to keep my personal and professional lives separate. I’m not Facebook friends with any current students (I’ll accept friend requests upon their graduation from university, though), I never tweet about politics or personal events, and I almost never post science articles or thoughts on my Facebook wall.

However, those personal and professional worlds do overlap sometimes. I have current and former work colleagues who have become friends. My personal interest in science frequently spills over into my professional involvement with science education.

Where is this leading us, you may ask?

Today I am sharing a collection of science news and updates from my Facebook feed. These are a few resources I’ve saved over the past few weeks and months because they’re either of personal interest or they’re directly relevant to units I teach – or both! Sometimes, life gets in the way, with things like visits from your mother, presidential elections, and an almost-one-year-old baby at home. So, without further ado, here are the science news items I’ve been following lately:

Elon Musk and Tesla reveal solar rooftops – Bloomberg News. Musk is one of my heroes because I think he’s a visionary who is unafraid to use his considerable funds to push the envelope of scientific innovation for the betterment of humanity and our planet. (Full disclosure: I own stock in Tesla.)

The “Zero Waste” grocery store – A Berlin shop which has developed a sustainable shopping model with the goal of reducing solid domestic waste. IB ESS topic 8.2: Resource use in society and 8.3: Solid domestic waste.

Zero emissions train unveiled in Germany – Not yet in service, but a step in the right direction to meet growing transportation needs. The train uses hydrogen fuel cells in place of diesel engines, and since it’s a public service, economies of scale may help advance more widespread adaptation of the fuel cell technology.

Climate change is having an impact on infrastructure – A story from Wired detailing how rising temperatures, thawing permafrost, and increased precipitation are having an effect on communities built permafrost. A case study for IB ESS topic 7 and IB Biology topic 4.

Captive breeding case studies from National Geographic – Students evaluate the effectiveness of various captive breeding programs designed to conserve biodiversity in this species-based approach to conservation. A solid link to IB ESS topic 3.

Are the water wars coming? – A look at dwindling freshwater resources in the face of growing human population pressure around the world. A good discussion for IB ESS topic 4.2: Access to fresh water.

How what we eat has changed (and will change again) – A short video from the BBC Future project examining the interplay between human population growth, food production, and ecosystem impacts. Relevant for IB Biology option C: Ecology and conservation, as well as IB ESS topic 5.2: Terrestrial food production systems and food choices.

Looking for good news about climate change? This is about all there is – The Washington Post outlines a scrap of good news regarding the rate of planetary warming in the context of the 2016 US presidential election. Useful for IB Biology topic 4.3: Carbon cycling, topic 4.4: Climate change, and IB ESS topic 7: Climate change and energy production.

That’s all I have time for tonight. I’ll post another set of news links soon-ish. And of course, I’ll have more on Twitter.

Happy learning!

Astronomy resources for students

Good morning!

Today I’m doing a little site maintenance, incorporating as many digital resources as possible into the various science pages on my website. The resources include simulations, videos, and activities created by other teachers and educational institutions. Instead of linking this blog post to a bunch of bookmarks I’ve saved over the years, I’ll just suggest that you check out my astronomy page under the “Sciences” tab on my homepage.

Among the many dozens of resources I’ve added, I think you’ll find something educational, engaging, and entertaining for a wide range of audiences.

Happy learning!

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.
