Teaching a Unit on Newton’s Laws of Motion

Teaching a Unit on Newton’s Laws of Motion

Are you teaching a unit on Newton’s Laws of Motion as part of your MS- PS2–1 or MS- PS2–2? Are you struggling to come up with ideas to help students understand how the laws apply to their everyday life?

Teaching a Unit on Newton’s Laws of Motion

Updated January 2024

My focus, during my two to three week unit on Newton’s laws of motion, is how everything we see around us is demonstrating the laws in some way. By the time the students finish the unit, they have a clear idea of how the laws are applied. 

What Students Should Know Leaving Middle School Science

Besides all of the concepts that we need to cover, what do students need to know leaving middle school science?

What Students Should Know Leaving Middle School Science

Updated May, 2024

Of course, we want our students to be good citizens and independent workers, but what else? Here is a list of skills that I think we will agree are critical to cover besides our extensive content.

Critical Thinking Is First!

In my opinion, critical, thinking should be the top of the list. Being able to look at data in a rational, organized way, and draw correct conclusions is important. So many “sources” are thrown at us from social media and other places. Teaching students to weed out “the real science” is critical. Many students may not understand the concept of “fake science”. Future voting decisions, homeownership, career choices, and so on will all need to be researched the correct way, with analytical thinking.

Learning critical thinking should be taught as many different ways as possible. I start my classes with CER image writing prompt bell ringers or I weave it into other assignments, such as analyzing a chemical reaction.(Using CER Image Prompts as Bellringers)

I find that praising the students for thinking hard is effective as long as it’s not overdone. Let’s be honest, most students look for quick, easy answers, so they should be rewarded for the extra brain work.

Organizational Skills

One of the hardest things to teach another person is how to organize themselves. So much of it is a personal preference and style. That being said, most middle school students haven’t really “found their groove” yet in terms of being self-sufficient and mindful of their time and materials.

That’s where we come in as teachers to model, model, model.


In sixth grade, I write up most lab result sections with data charts and questions that need to be addressed. Students need to see how it’s done, over and over. This means that by the time they are in eighth grade I can say “create your own data charts” for the lab that we are doing. 

As for student notebooks, I have gone digital, which was the best organizational change I ever made. I let the students design their own pages, and at the end of each unit I have a rubric which includes a table of contents, all homework, assignments, video, notes, book notes, lab reports, activities, project brainstorming, etc.   No more loose papers all over the place. 

If you are using paper notebooks I recommend one composition book per unit. Include a table of contents and a rubric to grade them at the end of the unit. I tried doing whole semester, or yearly, notebooks and it was a mess.

I have mentioned before that my ADHD students, or even those on the spectrum,  thrive with digital organization. I have a student whose handwriting is basically incomprehensible on a written test. I often have to ask him to translate. His digital notebook on Google Slides? Perfect score, every unit.

Teach Them to Be A Good Person

I will always pause my class if I hear someone not treating another correctly. My expectations are high and I never waver when it comes to bullying, insulting or excluding someone else, etc. Respect to themselves, teachers and others ranks high with what students should know when they leave middle school.  As they head for high school, there will be less forgiveness.

 I find boosting a child’s self-esteem goes miles with their behavior towards others. If your classroom is set up for “little wins”, then everyone gets a chance to feel good about themselves. I also use praise. Genuine praise. A little goes a long way!

Study Skills Are Essential

Let’s face it. Many students arrive in middle school without a strong set of study skills. A large part of teaching any subject is teaching students how to learn. Simply telling them to “study for the test” won’t cut it. 

They don’t even know where to start! 

Show them how to use flashcards, quiz websites, paired learning, games, etc. This will help get them motivated to study and to see the benefits. That said, I strongly believe in using many different types of assessments to hit all learning styles.   

           

How to Take Notes

Everyone should know how to take notes from someone who is speaking or from a text source. Again, we can’t assume students have this skill, and we must model it repeatedly. Give students templates to help organize their thoughts. I especially like Cornell notes and teach it as soon as they get into middle school. After they have completed any notes, I grade them carefully with suggestions.

 Since I have digital notebooks, I can watch the students on their iPads from my iPad. I often realize that I need to slow down and model more. Sometimes several students have barely any words written!

 Many students can’t process notes quickly, so they miss important points. It’s always good to have visuals and to wait for everyone to catch up.

Reading Comprehension and Pulling Information From Text

This is a very important skill.  I have been frustrated seeing even eighth graders read text and choose some of the least important information as they take notes! Guided notes and comprehension questions really work well to teach students how to glean the main ideas out of a text. 

Look for interesting reading passages that have students practicing over and over. Don’t shy away from textbook passages as students will need to use them in high school.

Compare Contrast Using A Venn Diagram

The idea of comparing and contrasting sometimes confuses students as they listen to a lecture, watch a video or read text. Being visual with a diagram helps. However, you will need to model a lot.

Look for situations for students to practice in all of your units. For example, have them compare and contrast the wings of birds and bats, a desert ecosystem to a grassland, or characteristics of a metal versus a nonmetal.

Construct and Read A Graph

When I start teaching graphing to my sixth graders, I start with students using graph paper to draw bar and line graphs. This way, students really understand how and why each plot point is located on the graph. 

We then move onto creating graphs with Google Sheets, Numbers, or Excel. Without doing it on paper first, these apps almost seem to create “magic” as they generate graphs from a spreadsheet. I’ve also noticed that if the app is incorrect at interpreting the spreadsheet, students will pick it up faster if they have done it on paper previously.

Before I did the paper activity, they had the wonkiest, meaningless, computer generated graphs but always with lots of pretty colors!

Search for graphs for students to read and interpret from real data. What trends do they see? How would the graph look differently if the increments of y-axis were changed?  Why would someone presenting the graph change the increments to make the data look more dramatic? Again, the importance of learning to distinguish “real science”. 

Research Skills

I love to bring up a picture of someone using the Dewey decimal system, in a library, and tell students how I did research at their age! We had to go through the filing system, which was difficult in itself, and then pray that the book that we needed was on the right place in the shelf, or even in the library at all! 

Yes, I’m dating myself, but it really gets the point across to the students as they sit there in shock listening to me.

Now the students have the problem that there is TOO MUCH information to weed through and a lot of it is unreliable. Start with explaining the reason why most teachers don’t allow Wikipedia for research and then how anyone can create a website.

OCTUPOD 

When doing research projects always ask the students to use citations and make sure you spot check them. Students must learn the laws of copyright and the consequences for plagiarism. They need to understand that just because an image is on the internet, that they can right click and save, doesn’t give them free rein to use it anywhere. Honestly, many adults still don’t understand that! Google images seems like an endless source of free pictures.

Students also need to understand the methodology for doing a research paper. Model how to outline their thoughts and how to structure the paper so that they don’t ramble randomly.

Work Ethic and Pride in Their Work

This isn’t so easy to teach, but if you set up the classroom with many little wins, it will become easier. Try not to focus on “getting it done for the sake of the grade”. This may encourage overwhelmed students to take shortcuts, or to shut down completely.

Breaks down work into little bites. Brainstorm with them and then do daily check-in so students feel accomplished. Reward the work that is done for those that struggle.

If an assignment is ripped out of a notebook and it tears, don’t accept it. Keep your standards high, and students will rise to them. Model at the beginning of the year what is acceptable and talk about having pride in their hard work.

Learning How to Communicate

This covers many aspects of being a good student and citizen. How should students ask for help in class? What should an email to you look like? Should it look like you’re texting your teacher?  Model this on the first day of school.  

Discuss how to work in a group where others may have different opinions than yours. Constantly remind them how they would prefer to be treated themselves.

Organizing a Project

Some teachers may shy away from long-term projects, such as Rube Goldberg machines, or other STEM activities. This could simply be because the lack of structure and chaos is just too much.

Try structuring the projects in doable sections with stop points. Implement daily rubrics to keep up accountability. When students learn how to work against reasonable deadlines, they are calmer and more organized with less “false starts”.

If possible, I try to keep the majority of the project work in school rather than at home. This means each student learns time management equally without having home distractions.

Learn Enough Basic Science Concepts to Make Intelligent Decisions

Of course, we have course content that needs to be taught. However, I believe that every concept should be brought into the student’s every day lives. Work hard to tie the topics into their world. Anticipate the “why do we have to learn this?” and START with the importance first. This helps the students be engaged and own the material.

For example, if you’re studying weather and clouds you can ask the students “how did you know, before you started this unit, that it might rain by looking at the sky?” Build on their existing knowledge, and they will see how knowing more simply enriches their lives. 

Yeah yeah, not every concept works out so well. However, the more you try to make it relatable, the better.

There are teachers who feel rushed to get concepts into students before end of year testing. If you choose even the shortest activities, that are relevant to their lives, you will find much more concept retention.

Conclusion

There are a lot of concepts that we need to get into middle school students, in terms of the actual science content. However, making them into good citizens, self-reliant learners, and organized workers, is critical as well. Please check out my other blog post on how to structure projects, keep students organized, set up digital notebooks, teach relevant topics, etc.

Introducing the Three Laws of Motion

I start my unit on Newton’s Laws of Motion with examples of balanced and unbalanced forces, as seen in my post called LABS WITH IPADS TO TEACH BALANCED AND UNBALANCED FORCES. This gives the students a basic awareness that various forces drive our world. 

When introducing the three laws, I start with my PowerPoint that introduces the wording of the laws. There are several ways we can approach using the PowerPoint rather than simply having the students sit and watch. The PowerPoint’s structure has an image with a question and students work alone, or in groups, to decide which one of the laws they are seeing. You could show the first slide with the image and then the following explanation slide. You could also challenge students to come up with all of the answers first before viewing the explanations.

 I created a workbook for students to fill out as they look at the images. There is a differentiated version with guided, fill in the blank reading. You could also put the PowerPoint at a center/station and cut up the workbook into task cards for students to work through.

Project Choice Board

I love to have ongoing projects as students move through a unit. This way they learn concepts themselves while getting the classroom information as well. Once students have moved through the PowerPoint mentioned above, I introduce the PROJECT CHOICE BOARD. Depending on the class dynamics, I may have the projects done completely at home, half at home or entirely during class periods.

 I prefer the half at home and half at school situation so I can see students working. Either way, I have them fill out the check-in sheets as they move along. If they have devices, they also photograph their progress. This simple act revs up the accountability so much!

I tried to create project choice ideas to hit the talents and interests of different students. They can also petition me for their own ideas. Sometimes their ideas are spectacular!

CER laws of Motion Image Writing Prompts

I use the CER image prompt bellringers each day to get students really digging into critical thinking. I love hearing students argue about which law the images best represents when multiple laws are possible. I have used the CER prompts for early finishers or even as an assessment instead of a test. (I rarely test this unit because once they have finished the PowerPoint, CER’s and project, they OWN the information!)

Drawing Vector Arrow on Images

Looking at the net forces acting on an object is something we do either in this unit or in the balanced/unbalanced previous unit. Students look at images and draw vector arrows on them to represent forces. We don’t use values, just the forces such as gravity, friction, thrust, or air resistance. I have them make the arrows thicker or thinner to represent which ones are stronger. 

For example, with a parachutist, the main arrows would be gravity and air resistance. The gravity arrow will need to be a bit wider as the parachutist is falling downward. If the air resistance was higher the parachute would fly up and away!

Finding the Resultant Force on a Graph

We dabble a bit with actual vector amounts on a graph where each block represents a Newton. Students draw the resultant force arrow after some simple math as to which direction is pulling or pushing the most. They also understand that multiple forces can be pushing/pulling in the same direction.

Looking at Friction as an Unbalanced Force

Delving deeper into unbalanced forces, I have a PowerPoint introducing the four types of friction which are sliding, rolling, fluid and static. The PowerPoint is laid out very much the same as the Laws of Motion PowerPoint. 

Students are given an image with a question and they must determine which of the four types of friction is being depicted. The following slide has an explanation. You can remove the explanation slides and have the students just work through the image slides. I also provide a workbook for the students to work through. There is a differentiated guided reading, fill in the blank version.

If you want to go deeper into teaching friction, I have a matching sort game that the students enjoy doing.  It would make a great center activity

Observing the First Law of Motion

Car crashes. Scary but very relevant when talking about the first law! By middle school age, students know that they should be wearing a seatbelt. However, can they  explain exactly WHY using physics?  After watching crash test dummies, especially in a school bus, you will notice that the students sit up and pay much more attention!

I give the students the reading comprehension passage about how car manufacturers have to understand and study the Law of Inertia to create safety features. Seatbelts, airbags, crumple zones and shattering windshields are discussed. The idea that our cars are DESIGNED to crumple blows the students minds!

The Second Law of Motion

Moving along to the second law, we practice F= ma problems.  We use the triangle to solve for either force, mass or acceleration. For example, to solve for mass, you can put your finger over the “m” and see that F is divided by a. Solving for acceleration, you can cover the “a” and see that F is divided by m.

Collisions Lab to Observe the Third Law of Motion

Now it’s time for a two to three day lab using the collision of balls as part of the third law of motion! Students find the mass of at least eight different smaller balls such as dollar store rubber or plastic balls, ping-pong balls, golf balls, tennis balls, etc. They set up two identical ramps facing each other and let the balls roll into each other.

Because I like students to predict what will happen, my lab takes more time. Since we also have iPads, a very cool part of this lab is filming the collisions in slow motion so they can be reviewed later. In fact, we don’t even fill out our data sheets until later as we watch the videos. If students don’t have devices, you can do it on your phone and show it to them. It really is fascinating! Even with no technology, the collisions can easily be observed.

After using the two ramps, we now put one stationary ball at the bottom of a single ramp and another ball rolls down to hit it. The different masses of the balls make for interesting results.

If you want to cover elastic versus inelastic collisions, the last part of the lab replicates the first, but this time uses clay rolled into balls.

All Students Love to Color!

If at any point you have early finishers, and need a quiet bellringer, I have two coloring sheets on the Laws of Motion and two on the Types of Friction. It is amazing how colored pencils, or crayons, and slightly lowered lights can relax and calm a class! They love it! The images on the pages can be discussed as they color quietly. These are also super useful if you have a sub!



Laws of Motion Exit Tickets

At the end of each class I hand out quick exit tickets. It helps me gauge which students are understanding the concepts and who needs center work or extra help. I don’t let students work in groups on exit tickets. Like I said before, with all this ongoing assessment, I don’t give a formal test at the end of the unit.

Great for gauging who needs more help and what you may need to reteach.

Conclusion

Learning basic physical laws is an important part of middle school science. Being able to recognize them in everyday situations is a great lesson in applying knowledge through critical thinking. I have these resources all in one bundle called Newton’s Laws of Motion Unit on Teachers Pay Teachers along with a free pacing guide to help you organize your unit.
