Marble Run Competition
Who can design and construct the slowest
marble run time?
Rules:
1.
Marbles will all be released from left corner of platform and roll to bottom
right corner exit.
2. You
can throw or push marble when releasing, just let the marble go when the
timer says go.
3. Once
the marble is moving it must continue moving, and you cannot touch the marble
with anything or move the platform. Any interference (e.g., blowing on it) will
mean you are disqualified.
4. The
slowest marble run wins but if the marble stops before the finish line it is
out of the race.
5. Play
fairly the judge’s decision will be final.
6. After
designing and constructing your marble run, you will have three test runs only
before the playoff.
Room 28 you have 7 lesson times for you to work with your group. Week 5
on Friday is the marble run and a special judge is invited to judge.
Goal: The
students will learn the effects of gravity.
Objective: The students will demonstrate and apply their
knowledge of gravity by constructing a marble run.
What we are learning by constructing a marble run is
Motion happens by the objects direction and speed
Forces cause changes in motion
Moving objects
have kinetic energy.
How is it going so far? (day 4)
Dariuz: Our group is working on making sure the marble slows down when it reaches the end.
Tyren: It's going good because we nearly have all the equipment's already to start in week 4. I believe our group will make it in the top three team.
Group 4: (Rahil, Ling Pin, Khent and Jared) Our marble run is going off good. We have got 4 marbles, 2 bottles, paper towels rolls, a box and some long tubes ready.
Seble: Our groups knows what everybody has to bring. We have decided what we are creating and have start to plan our design.
Ashley: We have a plan but have to get our stuff for the marble run. We just have to get more organised.
Nicky: It's hard for my group to do our plan. I don't know how we are going to get our plan ready. We are still deciding where the pipes will go. Our group just has to get organised and we might have a brilliant plan for our marble run.
Amy: So far I have thought about having concepts for each stage of this marble run. It's coming along quite well and I am thinking logically about my ideas.
Yhazmne: It has been amazing working with my group and its been a great thing for us working together.
Tresardi: The marble run is going good for us. We just need to bring our supplies on time. Our groups problems are not have any recycled materials to start on Monday. So we need to raid the staff room for recycled bottles as there are lots of milk bottles in the staff room.
Brianna: I enjoyed being with my group (6). I like discussing with others how we were going to plan our marble run. It has been a fun topic week.
Inoke: It's been good for our group as we have brought all our equipment needs for the marble run in class. We have made a simple model and tested it. I think we have a great plan but need to make sure it works.
What is force?
This week we learnt that a
force is something that can cause movement. We learnt about
different types of forces. As a class we examined a lot of
photos and discussed what force was being used. Then we used this
information on our worksheets. Forces we learnt were gravity,
buoyancy, friction and muscular force.
We started our new topic by
brainstorming "What
is Movement?". We came up with the idea
that movement is when something changes position. Some ways to move
we thought was turning, swinging, bouncing etc..
We walked around the school
and noticed that most things were not moving but we could make it move.
