Name of Activity Inclined Planes STOMP inclined planes, ramps, lego, simple machines, found materials Simple Machines, LEGO Building 4, 5 1 Hour Total Students will practice building inclined planes of all sorts (tubes, ramps, tilts) in order to have a ball object roll across the table/space. Use engineering design process to work and collaborate in groups efficiently. Introduce students to building inclined planes and inspire creativity for the future rube goldberg final project. found materials, legos, any classroom materials that seem helpful, tape, poster board, cardboard. Spend about five-ten minutes gathering groups and encouraging brainstorming before building. Provide each group an NXT kit for lego parts, tape, and poster board/cardboard. Inclined planes, slopes, speed, force Review inclined planes. Identify the goal: to allow ball to travel at least 2-3 inclined planes across a table or space. Divide into groups and allow students to develop possible solutions. Before giving materials allow each group to decide the best possible solution for their group given certain materials. Allow students to construct/build. Allow 5 minutes for Testing for each group before redesigning. Encourage communication within groups. Tell students to use more than 2-3 inclined planes. Have students incorporate a previous activity (an other simple machine) into their works. Simple Machines

Name of Activity Pulleys- Little Johnny and his Pet Cow Matthew Mueller Pulleys, simple machines, weighing, balancing, well Simple Machines 3, 4, 5, 6, 7 1 Hour Total Little Johnny’s pet cow has fallen down a well! You need to come up with a system of pulleys that will help little Johnny lift his cow out of the well. Get kids to understand the idea that pulleys can both change direction of motion, and lessen the amount of force needed to lift a heavy object. Lego pulleys, beams, axles, string, weights A basic understanding of pulleys and their uses. First have the kids try and make a wall of pulleys and show how it is easier to pull up a heavy object when using the pulleys.  Then challenge the kids to build a wall of pulleys that is capable of balancing as many weights on one side with just one weight on the other side. They can always try to balance more weights on one side and show that the more pulleys there are, the lighter the load will seem on the other side. Simple Machines
