Students will learn how sound travels through string and air by making telephones with cups and yarn. They will look at how sound waves move through the yarn and cup. Then they get a partner and do this with the application of a model telephone. Then they will be challenged to build the phone with string and cups for long distance. If time permits, they will try making the phone with fishing line and with nylon twine. Does this make a difference? Try it.

We are having students work with the principles of echolocation. They will work with a partner on this project where they understand engineers learned from nature how to use sound and radio waves to find objects. One partner will be blindfolded. The other partner will clap or snap their fingers in different locations to see if the blindfolded individual can point in the direction the sound is coming from. They write down each time they are correct and wrong. They can test different sounds and different distances. Try it.

We are having students do research on how to make a structure to withstand an earthquake. We will be using only toothpicks and small marshmallows. It needs to be at least the height of two toothpicks. They will be thinking about how to place, design, and build the toothpick structure. When complete, it will be set on a jello mold to see if it is a sturdy structure. Try it.

We finished our last project where students had to build a tower that was the tallest, strongest (held the most weight), and the most stable (stand tall without tipping over if shaken). We had them figure out what shapes would give their towers more stability. They could only use five sheets of paper, five straws, eight paper clips, and 40 cm of tape. Try and see how high and strong you can make one.

We had students make a parachute that would be able to drop to the floor without spilling the pennies in the cup. I gave them 1-3 grocery bags, string, a cup, and pennies to create a parachute. The goal was to build the parachute and then drop it and see how many pennies you could get to remain in the cup without falling out when it hit the ground.
Since I will not have class next Monday (11/16/15) due to a meeting after school, I would like students to create a Rube Goldberg project using everyday items found at home. They can get quite extensive but I don't expect a lot of synchronized or complicated materials. If they put together 5 to 10 items, that would be good. The end result is to squeeze toothpaste out of the container onto their toothbrush. If you don't know what Rube Goldberg projects are, watch the video below.
We are in the process of building "Puff Mobiles." You are welcome to buy the materials and assemble a Puff Mobile how you want. The students were told they could use 3 straws, 4 Lifesavers, 1 piece of paper, 2 paper clips and 50 cms of tape. They are not allowed to use any other supplies and don't have to use all of these materials. When constructed, they must blow on it to move. How fast can they get it to move by only blowing on it? Good luck.
