Lego WEDO Robotics is a project where students use Lego bricks and learn to do simple computer programming to connect their creations to motors, pulleys, levers and more to create robots! We'll create all types of projects that deal with Speed, Pulling, Robust Structures, Prevent Flooding and so much more! Each week students will be introduced to a new science and technology concept. They will build different objects based on the challenge of the day, and then they will experiment with scientific principles! Changing gears will help them learn about transfer of energy and increasing or decreasing speed. Pulleys and belts will be changed to affect speed and direction movements. We'll take turns using our new vocabulary to explain what's happening in our class, and this year we will start to document our findings! Each week will include all STEM disciplines as we use our Lego creations to experiement, challenge and learn. We'll learn about pushing vs. pulling objectives, what variables will effect speed, how to build robust structures, extend our science learning by modeling the metamorphosis of a frog, model plants and pollinators, prevent floods, sort and recycle and more!
Here's what it looks like for our Frog Metamorphosis lesson!
Objective: Model a frog’s metamorphosis using a LEGO representation and identify the characteristics of the organism at each stage.
1. We'll explore the frog's metamorphosis via video and understand the difference between mammals and amphibians. We'll discuss the changes that a frog undergoes, and how those changes effect the mobility of a frog in each stage.
2. We'll build a model of a tadpole (larva). Students will start to build a tadpole with only eyes, a long tail, and, at first, no front legs.
3. Students will follow the building instructions to morph the tadpole into a young frog that can move if activated by a program. One important, new feature that has changed in the young frog is the development of back legs. The walk module used in the project uses gears. These gears move the back legs. Students will once again document their models using pictures and/or sketches.
4. We'll program our new frog! This program will turn the motor on in one direction at motor power 8 for 3 sec. and then stop it. After building the young frog, students will then modify it to create their own model by changing the front and back legs, create other changes in appearance, and replicating the adult frog behavior. Students will learn how to use sounds or the Motion Sensor to change the frog's behavior!
For each of our lessons, we'll learn both building techniques, programming techniques and a variety of STEM ideas. Come do robotics the fun way and learn all about science, technology, engineering and math!
Our first week we will learn from our Dancing Birds! We'll build and program two mechanical birds that make sounds and are motorized to dance using a pulley and belt drive systems. Students will change the pulley and belt drive systems to learn how this affects movement, and then learn to increase and decrease speed. We will trace the transmission of motion and transfer of energy through the machine. Identify the pulleys and belt drive mechanism, and the effect changing the belt has on the direction and speed of the dancing birds’ movement. We will modify the dancing behavior by changing the pulleys and belt to affect the speed and direction of motion. We'll work to understand the concept of how the diameter of the pulleys affects the speed of the dancing birds’ movement. We'll start to learn fabulous new Vocabulary! Belt, pulley, gear, ratio, increase, decrease, and more! Blocks Vocab: Motor Power, Motor This Way, Motor That Way, Random Input, Play Sound, Repeat, Start, and Wait For. We'll move on to creating and exploring smart spinners, drumming monkeys and then several differen wildlife animals! In each lesson, all STEM disciplines will be incorporated and students will be bringing home new Evidence Of Learning Activity Sheets! These will help our learners describe what they have learned using pictures and words designed to pull out the core lessons for the day.
