MS: NGSS - Newton's Laws Lab Bundle + Friction: 4 Hands-On Investigations

Newton's Laws Lab Bundle + Friction: 4 Hands-On Investigations

Grades 6–8 • NGSS-aligned (MS-PS2-2, with MS-PS2-1 connections) • 4 complete labs

Give students a hands-on experience for each of Newton's three laws, plus friction, the force that explains why moving things stop. Each lab starts with a phenomenon students can see and feel. They then run a fair test with repeated trials, analyze their own data, and explain the results in a Claim–Evidence–Reasoning (CER) write-up.

The Four Labs

• Newton's First Law – Tablecloth Pull Challenge (about 45 min): Students pull a cloth out from under a cup slowly, then quickly, then with a heavier cup. They measure how far the cup moves and use the results to explain inertia.
• Newton's Second Law – Rubber Band Launch (about 50 min): Students launch a toy car with a rubber band, first changing the force (pull-back) and then the mass (washers). They graph the results and explain how force and mass together determine an object's change in motion.
• Newton's Third Law – Balloon Hover Disc (about 45 min): Students build a balloon-powered hover disc, compare it to a plain disc, time how long different amounts of air keep it floating, and identify action–reaction force pairs.
• Friction – Sliding Surface Lab (about 55 min): Students roll the same object onto four surfaces, from a smooth table to sandpaper. They measure how far it travels and explain friction as a force that opposes motion.

Every Lab Includes

• Teacher guide: a timed lesson flow, "Listen for" signs of understanding, common misconceptions with quick fixes, a CER scoring guide, and an NGSS standards page
• Student lab sheet: prediction, fair-test plan, data table with three trials and averages, analysis questions, a real-world connection, and the CER
• Answer key: sample data, answers, and CER examples at three levels (Meets, Approaching, Needs Development)
• Optional Honors Extension: force diagrams, net force, predicting and testing from graphs, and design challenges

Built-In Differentiation

Each teacher guide has a differentiation menu and an explanation of how to support:

• English learners: picture word banks, sentence frames, gestures and partner rehearsal
• Neurodivergent learners: role cards, visual step cards, check-ins and warnings before noisy moments
• Gifted and honors students: extensions that go deeper into the same standards rather than adding later-grade content

Standards

Aligned to NGSS MS-PS2-2, with MS-PS2-1 connections in the Third Law and Friction labs. The labs stay within NGSS limits: comparisons are qualitative, motion is in one dimension, and students change one variable at a time.

Easy to Prep

The materials are inexpensive classroom items: toy cars, cups, cloth, rubber bands, washers, balloons, old CDs, sandpaper and meter sticks. Use the labs as a sequence, or on their own to introduce or reinforce each law.

Continue Building on This Resource

• Forces and Motion: Investigating Interactions and Collisions (Complete Unit)

A 15-lesson NGSS unit (MS-PS2-1, MS-PS2-2) with:

1. labs and stations, graphing, and an engineering design challenge
2. a CER presentation
3. exit tickets, an end-of-unit assessment, and answer keys
4. differentiation in every lesson

These labs work well alongside the unit. For example, the Tablecloth Pull Challenge fits after Lesson 3 (inertia), and the Rubber Band Launch fits with Lessons 4–5 (force and mass).

• Forces and Motion CER Practice (Free)

Short forces-and-motion scenarios that give students structured practice writing Claim–Evidence–Reasoning responses:

1. a guided example, independent practice, a real-world application, and a Newton's Third Law challenge
2. standard and modified versions, so the whole class can work on the same scenarios
3. two answer keys with examples at three levels

Use it before the labs to build CER skills, or after them to strengthen students' written explanations.
