| STEM Roller Coaster Engineering | Students will investigate and describe different types of forces. They will complete an engineering design to build the fastest roller coaster. Students will use variables (distance and time) that change in relationship to each other to solve a real world problem. |
| Need for Speed | This Word document contains a STEM lesson in which students investigate how unbalanced forces change the speed and/or direction of motion in relationship to the mass of an object, using ratio and rate reasoning to solve real-world problems (with a force, speed, and mass connections). |
| Crash Test Dummies | Students will investigate inertia and Newton's laws of motion by completing an engineering challenge. Students will first investigate how mass affects the inertia of a person riding in a car that comes to a sudden stop. After analyzing the data and discussing the results, students will be asked to design a seat belt that will keep their clay person in the car without sustaining an "injury." |
| Skate Force - Using a Skateboard to Investigate Force, Mass and Acceleration | This lesson investigates Newton's First and Second Laws of Motion by observation and interpretation of graphs. It includes a stop motion motion video and graphs based on measurements of a skateboard propelled by an electric leaf blower with different sized forces and masses. It allows students to investigate the effects of forces produced by touch, magnetism and gravity. It introduces the concepts that acceleration increases with force and decreases with mass. |
| Up, Up and Away! | Students will participate in an inquiry lesson where they work in groups to launch straw rockets to the classroom ceiling using balloons as engines. Once the group is successful in reaching the ceiling with their rockets, they are tasked with modifying their rockets to carry paper clip passengers to the ceiling. |
| Inertia-tion | Students explore and define Newton's First Law and inertia. Students will develop their own skit to demonstrate the properties inertia and how common experiences with unbalanced forces help us understand Newton's First Law. |
| You've Got to Move It, Move it! | This STEM lesson is a lesson to be done over 3-4 sessions of 45 minutes, possibly longer for inclusion students who will need more direction. It involves lots of collaboration and the Engineering Design Process.
- Define the Problem
- Do Background Research
- Specify Requirements
- Brainstorm Solutions
- Choose the Best Solution
- Do Development Work
- Build a Prototype
- Test and Redesign
Students will be designing a vessel that needs to travel four feet, with the use of a fan, across two different types of string (fishing line and yarn). They will be expected to draw the design on an engineering page(s) with explicit details, illustrations, with an emphasis on gravity and the forces that are observed (tension, frictional, normal, pull, etc.). The students will be collaborating on the Law of Gravity, forces, and motion and take a short response assessment at the end of the activity.

| Is it Balanced or Unbalanced? | Students will be able to determine the net force of an object, identify the change in motion, and conclude if it is balanced or unbalanced. |
| Rolling With Rube Goldberg | From making breakfast in the Mary Poppins movie to the OK GO video "This Too Shall Pass" to the Target commercial, we've all seen those crazy, wacky machines that use multiple machines to complete a single task!! Challenge your students to graduate from using dominoes to knock over a cup to building their own Rube Goldberg machine!
During this lesson students will rise the challenge of building their own Rube Goldberg machine. Without even realizing it, students will incorporate their own sense of style of while applying science knowledge to complete this lesson.
Resources and documents are available for the daily lessons, teaching strategies, and any necessary worksheets. As well as a copy of the full (20 pages) lesson. |
| May the neutrally buoyant force be with you ! |
- This lesson helps students understand that forces affect motion and that some forces can be manipulated to be balanced or unbalanced with respect to motion. In the lesson, students use their knowledge of types of forces and free body diagrams to do an inquiry activity where they attempt to make a film canister neutrally buoyant in a 10 gal tank full of fresh water. (I have also used 2 L bottles with tops cut off and an empty pie pan to collect spillage.) Students need to predict, observe, and explain along the way as well as collect and record data to help quantify their results.
- After the lesson, students apply their new knowledge gained through experiential learning to real life scenarios in an abstract way as a formative assessment.

| Skateboard Design | In this Model-Eliciting Activity (MEA), students will use prior knowledge of forces and motion to design the best skateboard for different clients.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

| The Physics of Land Yachting | In this lesson, students will explore motion related to an object in terms of its change in position over time compared to a reference point.
Students will be given a variety of simple materials to create and test their very own land yachts to explore motion. |
| Air Force | The students will engage in an open inquiry developing an experiment pertaining to unbalanced forces.
The students will create an experiment and test their hypothesis.
Content Statement: Tell me if an unbalanced force affects speed, direction or both. |
| Balanced or Not | This lesson will help students clarify the difference between balanced and unbalanced forces and the students will be able to demonstrate the forces through the game tug-of-war. Students will be engaged in whole group discussion about their proir knowledge. They will also be engaged in small group discussion sharing examples they created and described about balanced and unbalanced forces. This lesson will allow the students to collect and record data from the different grouping scenerios of tug-of-war and answer conclusion questions based on the data collected. Students should gain a solid foundation about these concepts after the completion of this lesson. |
| Lunar Landers: Exploring Gravity | The attached engineering design lesson plan elaborates on the PBS Kids online resource and will probably take from 4-5 class periods. It takes the students through the engineering design process which includes the following components: Identify the Problem, Brainstorm and Design a Solution, Test and Evaluate, Redesign, Reflect and Share the Solution. |
| Parachutes For Sale | The students will be asked to help a company choose a design to market for their new business. The company gives students four prototypes to begin with, but asks the students to create one of their own if they wish to further the research. After choosing one of the models and writing a report to declare their findings and explain their reasoning, students will then be given restrictions to the parachute. They are asked to find a material that is light yet strong, and resistant to tearing and breaking. Students will have to create parachutes using the chosen model but made with different materials to establish the best overall material.
