Theme time frame: 2 Weeks
Student levels: WIDA Proficiency Levels 1-4
Big Ideas:
- Simple machines make work easier.
- Application of a force changes position and motion of an object.
- Simple machines can be used alone or in combination to solve problems
- Scientists and engineers observe and experiment to learn and solve problems
Theme connections to other content areas:
- Learners use formulae to estimate/determine mechanical advantage of simple machines.
- By observing the change in the numerators and denominators they predict what changes will increase or decrease the MA.
Objectives (with differentiation as needed):
Science & STEAM Objectives (F1)
- Students recognize and name simple machines: wedge, screw, ramp, lever, wheel and axle, and pulley.
- Students find and observe simple machines in their environment.
- Students identify simple machines as parts of toys and self-made devices. They will use machines and devices to solve a problem.
- Students identify and describe the action of a force using a machine to move and direct movement of an object.
- Students employ simple machines, e.g., hammers (lever), nails (wedges), screwdrivers and screws (lever and screw) for construction
- Students work well to collaborate with teammates.
- Students keep trying when things don’t work out right.
- Students use and describe the steps in the engineering design process (define a problem, generate ideas, select a solution, test the solution(s), make the item, evaluate it, and present the results.
- Students use tools to design, make, use, and assess technology
- Students use models communicate and test design ideas and processes.
- Identify objects from oral statements or questions.
- Name objects, diagrams, or pictures
- Match diagrams with words
- Produce short-answer responses to oral questions with visual support
- Follow two-step oral instructions
- Describe pictures, events, objects using phrases or short sentences
- Identify facts and explicit messages from illustrated text.
- Take notes using graphic organizers or models
- Categorize or sequence oral information using pictures and objects
- Formulate hypotheses, make predictions
- Use context clues to determine meaning of words
- Produce simple expository texts.
- Summarize information from graphics or notes; edit and revise.
- Identify cause and effect from oral discourse
- Present oral report of experiment and results
- Interprets written experimental data
- Produces original analysis from graphics and notes.
Learners use formulae to compute/estimate ideal mechanical advantage of simple machines to determine ways to improve machines.
Activities and Strategies
- Introduce machines with images, video, and classroom examples (stairs, scissors, pencil sharpener, rolling cart, doorknob, doorstop... (TPR)
- Practice saying key terms and identifying machines with “I have, Who has?” using words and pictures of machines. (Volunteers participate and act as models)
- Take a walk in the neighborhood to identify, photograph, sketch, and list simple machines encountered. Bring along picture showing machines for reference. (Volunteers participate to take photos and walk with small groups to discuss machines and record machines students find.)
- Play simple machines game, first as a group and then independently.
- Create machines using common objects (work in small groups with volunteers).(Volunteers help collect materials and manage them during activity.)
- Introduce steps in Engineering Design Process. Model with a group experiment. (See Engineering Process Handout; modify expectations for levels)
- Students design a solution to a problem, e.g., getting a wagon to change direction and roll to hit a target (work in small groups with volunteers); write up experiment.
- Use tools to build a birdhouse. (Volunteers work with small groups to ensure tool safety.)
- Create Bubble Map of Simple Machines, first as a group and then individually.
- Explain thinking maps to the group and create a Bubble map together.
- Learners create their own thinking maps showing the category “simple machines” and the machines that belong, with drawn examples.
- Learners present projects and maps to the class or a group of the class and receive feedback. (Learners rehearse in small groups with volunteers and teachers.)
Roles/responsibilities for teacher and volunteers:
(See descriptions with lessons.)
Assessment with differentiation:
See Rubric below.
Rubric is completed by observation and quizzes as learners complete unit tasks.
