Pop Pop Boat Project

For Unit 3- Earth's water and It's Properties, we were given a project to build a working pop pop  boat that runs on heat and the water it floats in. A simple pop pop  boat needs a steam boiler, a candle, and a boat hull to hold them. When a small heat source, such as a candle, is placed under the boiler (engine/ pressure chamber), a stream of hot water pushes out from the tubes creating a partial vacuum inside the boiler. The vacuum pulls in more water, water gets heated, and the process repeats until you remove the heat source. This is how the pop pop boat moves forward through the water.

CRITERIA FOR SUCCESS:

  • Decorated boat hull
  • Support a given weight (80 pennies for 10 seconds)
  • Working engine
  • Goes the length of a 3-meter (10 feet) gutter in less that 60 seconds (1 minute)


1.) Some of the materials that I used to make my pop pop boat were an alumni can, epoxy, cereal box, hot glue, straw, boat template, milk or juice carton.

2.) No, I didn't meet all the criteria for success because my boat didn't meet the criteria of going 3-meters, the reason why my boat didn't meet this criteria was because I had cut in my straw, which made the boat slow down.

3.) It is thermal energy when you apply heat to the boiler, and mechanical energy is when it converts energy into motion

4.) To prime the boat means to add water into the straw this step is important because the straw can get burned when heat is added, as well as the boat.

5.) My pop pop boat's design was one of the  best because most of the students who made the same  boat design went the length of 3-meters and made it in 60 seconds or less. In class data (period 4) one of the pop pop boats made it in 22 second with 38 seconds to spare, and in class data (period 6) one pop pop boat made it in 14 seconds with 46 spare, meaning that this boat design was one of the best.

6.) If i were to do thing project again I would change the straw to a sturdy one because by straw had a cut in it, meaning that it would not go as fast as it was expected to do so. One piece of advice I would give to a future STEM student would be to check every single of material because it can cause your pop pop to slow down.

Popsicle Stick Bridge Project

For Unit 2- Bridge Building, we designed and built out of Popsicle sticks. First, we researched some possible design and then worked on a presentation. The type of bridge my group and I decided is a Cantilever bridge. We decided to name our engineering firm D.A.M.M. Also, the name of our bridge is, Get the London Look. The criteria for success on this project is for the bridge to:

  • Stay under a budget of $500,000
  • Span at least 30 inches
  • Allow a toy car to successfully drive on the deck
  • Support a weight of at least 60 pounds  

Cost of Material

  • Wood glue-$20,000 per bottle
  • Regular popsicle stick-$1,000 each
  • Jumbo sticks-$2,500 each
  • String-$5,000
The total cost of my group's bridge is $407,500. After three weeks of building our bridge, we presented and tester our bridge project.

  1. )My group did meet all the criteria for success.                                                                                 
     2.) My group role was the Project Manger, as the Project Manger you had to supervise the entire group, make sure everyone is focus on building the bridge, make sure that the bridge/presentation is complete, and resolve any arguments between group members.       

     3. )My favorite part of doing this project was to actually build the bridge, and my least favorite thing was the fact that we had to do a google  presentation and later one present.

     4.) If I had the chance of doing it all over, I would change the whole bridge design and build a Truss bridge because I would like to make my bridge stronger than what it was before. 

    5.) One of the best moments that I had when I was doing this project was the fact I got to work with the people that I get along with  and we didn't have any major arguments, one of the worst moments that I had when I was completing this project was when one of our bridge side was unbalanced so we had to add a bunch of sticks which got everyone in my group frustrated.

   6.) If I were to give advice to  future students, I would say to build a truss because it is alot stronger and I would also say to make the deck strong too by adding sticks and a bunch of glue so it can stick alot better and so it will be able to hold more bricks.

LEGO BRIDGE CHALLENGE

We are currently on Unit2 - Bridge Building and my group members and I were given a Lego Bridge Challenge. We were given 16x16 base plates,and a variety of Lego bricks, plates,slopes, etc.The goal was to build a bridge that spams at least 20 inches, allows an object 6.5 inches and 6.5 wide(fire truck) to pass under the bridge, and support a load of 600 pennies(approximately 1,500 grams).We were given 35 minutes to build our Lego bridge.In addition, we independently built an online bridge using digital LEGO bricks using Build with Chrome.



                                      MY TEAM LEGO BRIDGE





 1.) In my opinion what I found more engaging was the team Lego build bridge because it was a group team challenge and In my opinion I like group team challenges.

2.) Yes my group and I meet the criteria fro success because it was longer then 20 inches,it allow the fire truck to pass under our bridge,and lastly it supported 600 pennies.

3.) One challenge my group and I faced was that our middle part of our bridge was unstable so to fix that we build a tower in the middle to support the bridge, and one challenge that I faced when building with Building with Chrome was that I would lose track of my pieces.

4.) If I had a chances to rebuild my bridge I wouldn't change anything because I was able to meet all of the criteria that was given to me.

Powered Racecar Project

Our second project for unit 1-Simple Machine was to design and build a race car powered by either a balloon,rubber band,or mousetrap.The project focuses on how the wheel and axle work,as well as how forces and motion apply to the car.In addition,after measuring the distance(meters)and time(seconds) on both test days,we were able to calculate the average speed (meters per second),using the equation average speed=distance/Time.In Order to earn an 'A' on this project,our powered race car needed travel at least 5 meters forward and accelerate up a 15ยบ ramp.We were given two opportunities to meet criteria for success.













1.My mousetrap powered race car works by using A mouse trap for a motor, to attach a string to the mouse trap and axle in this method one end of a string is attached or tied to the the mouse trap on the other end of the string is  wound around the axle the mouse trap springs and stretch and now you have your stored energy and as a mouse trap car is released the mousetrap pull the string off the axle causing the wheels to turn and off the vehicle goes.

2.The materials that I used to construct my power race car is foam board,hot glue gun,mousetrap glue sticks ,CDs ,three sticks,paint,duck tape.

3.My Powered race car traveled further than 5 meter,The farthest distance my car traveled was 10 meters and it did not accelerate up the 15° ramp.

4. After test one we did not modify/ redesign our project because after we tested our race car,our race car was accelerating just fine and we thought as a group that our project was going to go up the ramp  the second time.

5. Our average speed of our powered race car for test one was 0.75 and for test two it was 0.55

6.some success that we face during our project was that a race car traveled more than 10 m and some challenges we face during our project was that at first our race car didn't accelerate as fast as we wanted it to,One thing I would do differently would be to add a bigger mousetrap so it would be able to accelerate more faster and be able to go up the 15° ramp.

Catapult Project

For unit 1-Simple machine,we worked on recently finished the catapult project.
A catapult is a device used to launch an object some distance.We examined the concept of levers,such as the effort,fulcrum and load,as it relates to catapult and other tools we use in our daily lives.In addition to identifying types of catapults,we learned abut projectile motion and mechanical advantage.The goal of the this project was to design and build a catapult that can launch a load with distance and accuracy.We tested our catapult to determine how far it can launch a ping pong ball and how many time(out of 4) it could hit the target(castle) that was placed at distance of two meters.Wee were given two opportunities to meet the criteria for success.

                                                                          Fron View
                                                                                                                          Side View

           My Catapult                                           


 










Questions:
1. What materials did you use to build your catapult?
The materials that I use to build my catapult was popsicle sticks,wood glue,rubber bands, and a spoon.
2.What type of catapult did you design?What class lever is your catapult?
My catapult design was a mangonel and the mangonel is a 3rd class lever.
3.How far did your catapult launch the ping pong ball for trail#1?trail#2?Did you change your catapult fro trail#1?Why or why not?How accurate was your catapult hitting the castle for trail#1 and Trail #2?
For the first trail my catapult launch the ping pong ball 7ft and for the second trail my catapult launch the ping pong 16ft,my catapult accuracy for the first trail was 2 out 4 and for the second trail was 1 out 4,and yes I did change something,I added an extra rubber band so it was able to shoot farther.
4.What difficulties did you experience when building and/or testing your catapult?
One of my difficulties while I was building my catapult was that I added a lot of glue,which the glue made my catapult wobble.
5.What are some important concepts/ideas you learned while designing your catapult?
Some important concepts/ideas that I learned while building my catapult was always ask your teacher for help,and don't add to much wood glue.
6.If you were to make another catapult,what would you change to make it launch farther,and more accurate?
If I were to make another catapult I would change my design and make a ballista because it shoots far and the ballista has an accurate aim.

Spaghetti & Marshmallow Challenge

My team and I did the Spaghetti & Marshmallow Challenge.First we were given 30 Spaghetti sticks,a yard of tape,a yard of string,and lastly one marshmallow.Our goal was to design a structure that can stand freely and it had  to be 14 inches tall with the marshmallow standing on top of the structure and we had to do it in 30 minutes! We had two opportunities to meet our goal. 



1.Yes my team and I meet criteria for success because our structures past 14 inches(the goal) with the marshmallow on top in 30 (min)
2.The best feature of our  design was that it was a triangle on top of another triangle.
3.One thing that I liked about this challenge was that I got to work as a team and everyone was giving ideas.
4.The most difficult thing about this challenge was picking an idea.
5.Yes me and my team build build a better structure because the first one was just a pyramid  going up and it was not as stable but the second was a triangle on top of an other triangle.
6.Me and my team members communicated good because we were able to meet our goal.
7.Everyone was helping for example one person would cut the tape,and another would hold the structure while the other one was adding stuff to it.
8.One thing that I learn about engineering was that you have to have patience.
