Marble Ramps With Rulers

If i set up a ramp that was 4 blocks high the marble would probably roll somewhere in the 50 s.

Marble ramps with rulers.

The ramp should be positioned so that the marble rolled down the ramp will roll across the floor and collide with the wall. Conserving energy have students explore potential and kinetic energy by releasing a marble on a simulated roller coaster. If i start. Suzanne if i could launch my marble off a ramp that started as high as a desk i could really get it to roll far.

Popular marble experiments help students discover basic principles of energy mass velocity and momentum using ramps rulers and cardboard tubes. If you want a shallow marble ramp you might need to make some more ramps. I built this track myself my kids didn t help but it was based off inspiration from kids at a recent lego event we attended. The marble went 25 then 34 then 47 cubes.

In this post i m going to show you how to build a really awesome lego marble run. Position one marble at the top of the ruler 30 cm and. Fix the ruler in place with tape so it will not move from one experiment to the next 2. Students then suggest i roll the marble on top of the ruler since it has a groove.

You should have at least seven ramps. Now take the biggest triangle and draw the marble ramps using a pen and ruler make the ramps 1 5cm or a bit bigger depending on the size of your marbles. Put a marble at one point along the ruler but don t tell the students the cm position of the marble. I implement their suggestion and the marble moves in a straight line and hits the sail.

Potential energy is the energy that is stored in an object. Gavin it s kind of like when i ride a bike. Some students will likely say that the higher the marble is on the ramp the farther the cup will move. Ramp set up higher and higher.

An example of potential energy is a stretched out rubber band the farther you stretch it the more potential energy it has. You ll be amazed at the lego marble runs they can create. Students suggest i roll the marble and try to hit the sail. A truly admirable marble ramp was distinguished by the length of time taken by the marble to emerge the longer the better and by the variety of interesting noises it made on the way.

Release the marble and let students observe that the marble moves the cup along the tabletop. Place a half cup at the base of the ramp so that a marble rolling down the ramp will enter the cup and push it. Once you ve finished drawing the ramps take some scissors and cut them out. Lean a grooved ruler or paper towel tube against the textbooks or other props so that the top end is at the 5 cm height while the other end is touching the floor.

I implement their suggestion and the marble misses the sail completely and bounces off of the table. The ruler should be placed so that the lower numbers are at the base of the ramp.
