A LGODOO
Teachers, students Getting familiar with the Algodoo environment, the tools and menus by creating a
scene and interacting with it. Getting familiar with the Algodoo environment 30 – 60 min Let the students explore the possibilities of Algodoo. Brow through the menus to e what is in there. By choosing File:Load scene you can load different scenes. The simulation can be started and stopped at any time. The accelerometer can be turned off and on. While the simulation is running you can pull objects by using the hand tool. You can add new objects any time. Your simulation is saved by choosing File:Save scene.

YOUR SCENE
Create planes, one on each wall/floor/ceiling. U at least two boxes U at least two circles. U at least one spring. Make at least one free form. Tilt the device to make u of the accelerometer. U the CSG-tool to create an object. U the knife to cut objects into pieces Change properties (color, material) of one of the objects. Take a snapshot with the camera and add the object to your scene Add a hinge and assign a motor to it. Create something that moves by using hinges, motor, or by constructing own driving arrangements. Add a pen to an object in order to follow its trajectory

OF GRAVITY
Teacher: Key Stage 3 (ages 11-14) This lesson plan is not intended to be handed out to students but to be u as a teacher preparation and tutorial. The centre of gravity of a body is the point in which the mass of the body can be concentrated. Gravity acts as if all the mass of the body is concentrated
in that point. This lesson allows the student to explore the concept of gravity and to find the centre of gravity of an irregular body. Understand and explain the concept of centre of gravity. Discuss methods of finding centre of gravity of an irregular body. Model a situation for centre of gravity and create an interactive simulation. 30-60 min centre of gravity, mass Discuss the centre of gravity. What does it mean and what effect does this phenomenon have in real life? How can the centre of gravity of a body be found? Discuss possible ways of doing this with the class and put up suggestions on the board. Discuss how this can be visualized and explored in Algodoo using the Classmate PC. Let the students create scenes in Algodoo using the suggestions you came up with together or let them u their own ideas. Help the students make decisions and ask guiding questions. Encourage the students to follow the procedure Create – Predict – Interact – Evaluate. Allow the students to follow-up and share their experiences in class after the simulation.

Create a scene Create an irregular body, using for example the brush and the CGS-tool, or u the camera to take a picture of your friend and u her shape. Cleancut the picture and suspend the bod
y using a hinge. Make a prediction Estimate the center of gravity. Run/Interact Start the simulation. The body will probably start oscillating so it might be necessary to help stopping it using the hand tool. When still, glue a massless, vertical, straight line from the hinge. Choo another spot for the hinge and glue another massless, vertical line. Repeat a couple of times to get 3-4 lines through centre of gravity. Evaluate Where do the lines interct? Compare with the gravity vector.

TRUCK
Teacher: Key Stage 3 (ages 11-14) This lesson plan is not intended to be handed out to students but to be u as a teacher preparation and tutorial. Investigate the critical point when a truck is tipping over. The position of centre of gravity is crucial for the balance of a body. This lesson allows the student to explore the concept of gravity and to find conquences rising from the position of centre
of gravity. The example explores what caus a loaded truck to tip over, when does a book fall off a table and when does a person loo balance. Understand and explain the concept of centre of gravity. Understanding conquences of the position of the centre of gravity of an object. Understand and explain why an objects tips over/loos balance. Model a situation which demonstrates tipping over and create an interactive simulation. 30-60 min centre of gravity, mass Discuss the centre of gravity. What makes an object tip over? What does it mean and what conquences does this phenomenon have in real life? Discuss possible situations of “tipping over” in class and put up suggestions on the board. Discuss how this can be visualized and explored in Algodoo using the Classmate PC. Let the students create scenes in Algodoo using the suggestions you came up with together or let them u their own ideas. Help the students make decisions and ask guiding questions. Encourage the students to follow the procedure Create – Predict – Interact – Evaluate. Allow the students to follow-up and share their experiences in class after the simulation.

Create a scene Create a plane and make sure friction is high enough to prevent sliding. Create a number of “trucks” by using boxes with different density modeling different ways of loading a truck. The truck should be en from the rear. Make a prediction Which truck will tip over first when the plane is tilted? Run/Interact Start the simulation. Tilt the Classmate PC and watch the trucks tip over. Evaluate Why do the trucks tip over? How should the truck be loaded in order to prevent tipping over? Where is the centre of gravity? Note: Obrve the position of the gravity vector. Revi scene Rearrange the loading in the trucks in order to make them more stable. Make a prediction How much can the plane be tilted before a truck will tip over? Which truck will tip over first?

SEESAW秋天丰收
Teacher: Key Stage 3 (ages 11-14) This lesson plan is not intended to be handed out to students but to be u as a teacher preparation and tutorial. This lesson allows the student to explore the balance of a esaw. By adding weights to both sides the esaw can be kept in balance when using different fulcrums. The relation between mass and distance from the fulcrum can be investigated and give an understanding about lever arms and moment of forces (torques). The example also opens for creating and working with balance scales. Understand the relation between mass and distance to maintain balance of a esaw. Understand the basic principles for a weight scale. Understand what a lever arm is and its relation to moment of force. Model a situation for balance and create an interactive simulation. 30-60 min centre of gravity, moment of force (torque), lever arm Discuss balance of a esaw. How is it constructed and how does is look when no one is playing with it? What happens when kids of different sizes start playing it? Does it depend where they sit, how tall they are, what mass they have? Discuss different aspects of playing with a esaw in class and put up suggestions on the board. How can the centre of gravity of a esaw be found? Discuss how this can be visualized and explored in Algodoo using the Classmate PC. Let the students create scenes in Algodoo using the suggestions you came up with together or let them u their own ideas. Help the students make decisions and ask guiding questions. Encourage the students to follow the procedure Create – Predict – Interact – Evaluate. Allow the students to follow-up and share their exp
eriences in class after the simulation.. Evaluate What happens when an object is moved towards or from the fulcrum respectively? What is the relation between mass of the object and distance from the fulcrum? Relate the mass of the object to the normal force and gravity. Suggestions for additional scenes modeling center of gravity, moment of force and lever arm Balancing book: When does the book fall off the table? Create a book sticking out from a table and find the critical point when the book falls to the floor. Falling friend: What makes your friend fall with respect to centre of gravity? Take a picture of you friend, clean-cut and stand her on the floor. Tilt the device until she falls. Weight scales: How is a simple scale constructed? Create a scale and u if for weighing different objects.
