Gotta do electrical circuits virtually? Here’s how!

This activity directs students to experiment with the basics of circuitry, virtually. It works great when distance learning (its a Google doc worksheet) is necessary or as an introductory activity to a hands-on circuitry lab.

The worksheet guides students in making and analyzing circuits using this interactive seen in the video below.

Watch the video for a peek at how the virtual circuit builder works!

Here’s a peek (below) of the 2nd page of the activity worksheet – see the whole thing at this link.

Science Lab or Activity Rubric – Promote Collaboration Skills!

rubric cover imageI really needed to find a way to encourage appropriate lab behavior both in terms of following lab rules and collaborating with partners. Over the summer I came up with this easy-to-use lab rubric and the results have been outstanding!

Each student begins with 10 points (you can change to any points you prefer – the document is in Word so that it can be edited).

Students are told that they are being graded and each category is explained. They understand that they begin with 10 points and lose a point (or sometimes 1/2 a point) when they break a lab rule or are showing lack of effort and teamwork.

All it takes is ONE TIME of (emotion-free) calling out a student and everyone else pretty much stays within the lines of 10-point safety!

This RUBRIC is only 99 cents! 

By the way, it is VERY IMPORTANT to have clear, enforceable lab rules. The biggest mistake any teacher (or parent) makes is setting a rule and then not fully enforcing it at the first opportunity to do so. Do yourself a favor and your students – BELIEVE in your expectations and enforce them equally and always.

Rules I always enforce (within the letter and the spirit of the law):

  1. No interrupting members of other groups – no talking to or bothering anyone in a different group. This disrupts the lab and gets lots of people off task quickly.
  2.  Stay on topic – fooling around and talking about other things results in delays in work being accomplished and diminishes the learning opportunity for everyone involved.
  3.  Use lab supplies appropriately only – any lab supply, including the Slinkies and toy cars, are for scientific use as allowed in the lab. Any misuse results in a loss of a point and can lead to other consequences as well. Students will not respect the science supplies if this expectation is not fully expressed and enforced!
  4.  Stay at your station unless otherwise directed. Students cannot just wander around at their leisure. Doing so leads to misbehavior so be clear about this and enforce it!
  5.  Follow clean up procedures (as directed). As we often do in life, I had to learn the hard way about this important procedure. Students need clear instructions on what they are expected to do for clean up. Be clear about how to dispose of the disposables, for example.If you are new to teaching then it may not occur to you that you have to be explicit about rules like these.

Teach, demonstrate and practice lab rules and procedures. Believe in their power to promote learning (they do NOT diminish fun, they stop chaos!). Rules are meaningless without (emotion-free) enforcement.I didn’t make this stuff up of course.

Much of my success with lab/classroom management comes from the wonderful work of Check them out if you have a hard time believing in the educational power of enforcing your rules.

New Lab Activities!

I’ve recently turned two more of my lab activities into products available to other teachers through my TpT store.

Activity: Predict, Measure, Graph and Analyze with Tasty Candy!

I use this activity with my 6th graders as they are learning to make quantitative observations, but I think it’s useful for 7th-9th as well.

Students enjoy getting to eat the candy after they make their measurements. Skills practiced are making a bar graph, calculating averages and percentages and comparing their data to the data of other students.

My 6th graders come to me without much experience with measuring and evaluating quantitative data. Math is not applied to scientific thinking in the lower grades unfortunately! While I think they would benefit from quantitative thinking in science in 4th/5th grade, I am happy to introduce them to the world of data!

Inquiry Activity: Magnet Challenge! Includes Google Doc Worksheet Option

I was really happy with how well my students did with this activity. I created it over the summer to use as a beginning-of-the-year warm up to remind my 7th graders how to collaborate and get back into academic work. I enjoyed their enthusiasm for the activity as they got beyond their initial struggle with inquiry-style experimentation. Fear-of-the-wrong-answer-syndrome impacts many of my hardworking students! I like the challenge this activity provided to set aside this paralyzing fear and just enjoy experimenting with magnets. The link includes a product PREVIEW so you can see student work.

Metals Activity: Malleable, Ductile, Shiny, Conductive, High Melting Point

I made this inquiry activity years ago, but finally got around to making it available to teachers like you just recently. I like the way my students have to come up with their own ways to demonstrate the properties of metals with nothing more than a piece of aluminum foil. The only other supplies is a heat source such as a hot plate and some way to test electrical conductivity (easy to make).

The activity has a built-in assessment so you do not need any separate way to assess understanding.

You can have students partner up for this, but I like for them to work independently with this activity. Too much partnering leads to too much reliance on others to do the thinking. With a piece of foil being the only individual supply needed there’s no real need to share.

Take a look at the PREVIEW for this activity to see some student work!

Science Lab Challenge – Practice following directions and using lab equipment

lab equipment lesson thumbnailI developed this quick and easy activity to teach my middle school students about common lab equipment, safety procedures and how to work together in a lab. It’s also specifically designed to help them practice the hardest skill of all – following directions!

This activity encourages students to document and learn from their mistakes. They do not lose points for making mistakes; rather, they gain points by recognizing and correcting their errors. The pressure for perfection is off and the pressure for learning is on!

The activity is quite safe since the only substances used are water, food coloring, vinegar and baking soda.

Objectives of this activity are for students to be able to:
• Follow step-by-step directions in a lab
• Identify common lab supplies and their uses
• Cooperate with group members to complete a lab activity
• Explain basic safety practices that must be followed when doing a lab

See what other teachers have to say about this activity here.

Laying the Foundation…


Teaching Middle School Chemistry

As a middle school teacher I find one of the hardest parts of my academic work is to really pinpoint exactly what my students need to know at this level. I’m a details person and I like to dig into the subjects that I teach. My fear is that I’m not laying out the big picture well enough and get stuck in the weeds with the details. But the big picture doesn’t work without enough details so I can’t ignore the details. Now you know the type of arguments I have with myself.

I love chemistry. I love elements. I love atoms. I love electrons. Yes, I’m a total geek, but I can’t help thinking that it’s beyond amazing that we know so much about things we can’t directly see or experiment with. Everything is through indirect methods and ingenious ones. I’m always amazed at the creativity that it took for people to figure out all that we know about atoms. (This is somewhat beside my main point; except, the fact that I think it helps to be excited about what you teach, otherwise teaching can really suck.),

So, back to what I do with teaching chemistry to 8th graders. Below I’ve laid out my outline of topics in the order that I think works, after 8 years of fiddling with it. Every system has limiting factors so in figuring out what to teach I had to respect my limits – this is an introductory level AND it’s only a UNIT of 8th grade, NOT a year long course in chemistry.

My development of this unit reflects my personal teaching philosophy:

I am dedicated to giving my students an opportunity to build a foundation of knowledge and skills to take into high school courses. I want two things for them:

        1. They can walk into a high school course and feel confident that the knowledge they already have will support them in learning more. I am lucky in that I see my former students often and I ask them if I am doing a good job at this and they say yes. This comes from C students too. And, they are really thankful for it which is a major inspiration for me to keep pushing forward (otherwise, like I said, this job could really suck).

        2. I don’t expect my students to recall all the facts they learned, but I do hope they learned about analysis, drawing logical conclusions, and writing with precision. I do hope that they remember about analyzing experiments – the role of constants and variables, testable questions, placebos and trial sizes. At least this skill may save them from believing everything that they read on the internet and falling for junk science.

So, the question is, what are the foundational concepts that set the stage for deeper learning in the future? Also, what skills do I want them to learn in middle school that will give them more confidence for higher level courses, in this case, chemistry?

Here is my outline of concepts taught with some main points/vocabulary stated as well. It is just an outline so imagine that I’m filling in the blanks with (hopefully) all of the right details. The list is generally in the order in which I teach these concepts. I’ve included links to some of the lessons/worksheets I created to teach this unit. I’d love to know what you teach for middle school chemistry. Please share your comments and suggestions!

Atomic Theory and Structure of an Atom

  • Bohr’s model for understanding the atomic structure of the first 18 elements – protons and neutrons in the nucleus, electrons occurring at certain distances from the nucleus; these distances are energy levels (or shells); electron configuration rules for the 1st three energy levels. (no orbitals at this level)

  • Atomic theory history – Democritus – Dalton – Thomson – Rutherford – Bohr – quantum mechanical model – Chadwick

Pathogenic and Beneficial Bacteria Introduced

Includes a Google Doc Version for Distance Learning!

bacteria webquest cover

[Students – please scroll down for the webquest links]

The hardest part of teaching 6th-9th grade science sometimes is figuring out what information is essential for these students to learn so that they develop important background knowledge to propel them forward to deeper learning in upper high school courses and beyond. I struggle with this question all of the time.

It has taken a few years, but I think I have found the right balance when it comes to teaching about the bacteria kingdom. We learn about this subject twice – first, when study the basic characteristics of the different kingdoms of life. Second, when we study pathogens and the immune system, which is when my students do this webquest.

I developed this webquest to engage my students in the reasons WHY we study bacteria. This could seem like a boring subject, but bacteria are amazing, complex and scary. They are a part of our history as humans and literally a part of our bodies. Learning about bacteria can be frightening at times given the havoc they can cause, but its through learning and studying them that we quell our fears.

For one, kids often are given the impression that all bacteria are bad and disease-causing. The exact opposite is true and most bacteria are harmless or are doing a job directly for us or in the environment that we rely on. Learning about this makes them a lot less scary. And yes, some do harm us, but by studying them and engaging with them, we learn to stop and prevent their infections.
