Teacher's Note: Fixing the Frog's legs so that it can jump

The following tasks aim at showing the friction effect. Let a robot move on stone/wooden floor and then on a carpet or surface which creates more friction (vinyl fields are very suitable for the experiment) and the frog will instantly start moving. An important feature of friction is that it is created between two surfaces which means that we should increase the friction between the surface and the legs of the frog so that it can jump. As it is difficult to change the surface of the floor, students’ task will be to put something under the feet of the frog in order to increase friction.

Courses and lessons with this Tutorial

This Tutorial is used in the following courses and lessons

[In Development] The fun level - Game-oriented introduction to LEGO robotics

A level, designed for introduction in LEGO-robotics, focused mostly on games. We use goal-oriented challenges to make the students want to accomplish a certain task, learning a lot in the process. Some of the games we have included here are football, bowling, paper-plane competition and many more. It is suitable for studens 8 to 12 years old, but even older students will have a lot of fun with the activities.

This is a brand new course that we are experimenting with in a groups in June 2019. Keep in mind that it is possible to use it for summer camps and groups, but there are a few lessons that will be improved on the fly.

Lesson 2

Introduction

Today we are going to build a Frog robot.

Level D1. "Animals". Robotics with LEGO

This is the seventh level of the Robotics with LEGO curriculum for students in third or fourth grade.

In this level students focus on the rotational sensor that is part of every motor in the robotics set.
Robot constructions imitate animals and their behavior. Students create programs that check whether the robot's claws or pecks have successfully caught an object. That sensor in the motors allows the robots to go back in their lairs even after the use of unlimited movement.
