Physics & Physical Science Demos, Labs, & Projects for High School Teachers

My Favorite Place for Science Supplies

Posted on: July 23, 2008

I love Harbor Freight Tools.  If you teach science and have one of these nearby, you must get there.  The place has tons of tools at bargain prices.  They are made overseas, true, but they warranty everything and I have never had a tool fail on me.

The picture on the right is a digital caliper they sell.  I use these for a lab on density and also when we are discussing precision.  These calipers work great and they are on sale right now for $7.09.  Yes, under $10, try getting something like that from Carolina or Frey or one of the other school lab suppliers.

Another item I purchased from them by the hand full are digital multimeters.  Again, from the supply catalogs, expect to pay about $80 for one inexpensive meter.  At Harbor Freight these babies go on sale for $2.99.  I bought a couple for my house, and even though I have a $100 Fluke meter from my engineering days, I tend to take out my $3 meter when I need a reading.  Of the ten or so in my classroom, I’ve had one of the leads break in two years of classroom use.  I just bought a whole new meter for another $3 and didn’t worry about it.

Here’s another gem, a non-contact thermometer.  I got this beauty on sale for $9.99, and I loved it so much I bought another.  These are mine, but I bring them in when I need them for a lab.  One day I’ll purchase them for the school, I’ve just been lazy about it so far.

You can find all this and so much more.  Here’s a few other items I own and use for school:  A dual temperature heat gun for $10 (used to launch hot air balloons), a set of six pliers (electronics sized) for about $5, pulleys, sandpaper, and inexpensive but decent castors in all sizes.

You can look up where your local store is located and all the items including sale items at:

What’s New in 2013/2014?

Every year brings a change, this one is no exception.

I will be picking up the sophomore honors Algebra II class to keep them separate from the juniors. This should help accelerate them and put them on a stronger track towards Calculus. Looks like there will be only one section each of Physics and Calculus, but still two of Robotics & Engineering.

Hot topics this year are going to be the Common-Core Standards, Standards-Based Grading (SBG), improving AP Calculus scores, and somehow adding Python, maybe as a club.

Polls in the sidebar

Just a quick poll to help me understand who is stopping by my blog.

Yeah sure, lots from America, but look who else is here…

If you are badly in need of more email or for some reason jonesing for a physics fix, enter your email address so I can bother you with my newest rant on science.
