General FAQs

What is required to participate?

  • Each school can have one team.
  • Each team needs a head coach.
  • Elementary can officially register 16 students, but your team can be larger or smaller.
  • Middle or high school teams can register 15 students on their "primary" team; up to 15 additional students can compete on an "alternate" team.
  • The team registration fee is $100 for elementary; fees are $315 for middle and high school teams.
  • Many events require support materials.
  • Event coaches are a great help.

Who participates?

  • Public and private schools from Macomb and St. Clair counties
  • More than 70 elementary schools
  • More than 40 Middle and High schools
  • Some teams formed 25 years ago. Some started last year.

How long does the season last?

  • Teams register in the fall.
  • Middle school and high school coaches get trained by December.
  • Elementary coaches get trained by January.
  • Kids and coaches prepare for several months; workshops are offered to help for some events.
  • Middle and high school teams can attend practice "invitational" tournaments.
  • Some school districts host practice tournaments for elementary teams.

When and where is the tournament?

  • The regional tournament for middle and high school teams is Saturday, March 23rd, 2013 at Macomb Community College south campus.
  • The top teams (~20%) qualify to compete at the State tournament at Michigan State University about a month later.
  • The top two middle school and two high school teams from the state tournament qualify for the national tournament.
  • The regional tournament for elementary teams is Saturday, May 4th, 2013 at Macomb Community College south campus.  There is no state-level tournament for elementary.

I'm just starting a team. What help can I get?

  • Macomb Science Olympiad provides rule books, and workshops for coaches and kids.  See the calendars in each section (elementary, secondary) of this website for more details.
  • Be sure to attend informational meetings for the Head Coach.
  • You can be mentored by an experienced coach.
  • Community organizations provide workshops.
  • We have published a coach's handbook for elementary and one for secondary.
  • Event rule clarifications are published on this website.

What are the events?

  • The elementary tournament is comprised of 16 events.
  • The secondary tournament has 23 events each for middle and high schools.

How do I register a team?

Follow the instructions the bottom of this page

How can I find the elementary event rules on this website?

Click on Events on the left side of this page, then click on Elementary Event Rules. The page that opens allows you to download and print the entire current rulebook, or the rules for specific individual events.

Foam clarification

The foam is just over 1/2" in depth.  

 

the foam will cover the bottom of the pool.

 

the bucket will sit atop teh foam

 

there will be no foam inside the bucket

Will there be questions around finding or calculating Voltages or voltage drops across components (resistors / bulbs) in a SERIES circuit?

 There could be measurements or calculations on series circuits. If there is, it will just be simple addition or subtraction.

Besides knowing the symbol, what will the students need to know about diodes?

Know their effect on a circuit. They may have to identify it's use in a circuit, ie Will a bulb light or not. They may be asked to use on in a circuit.

Please confirm the schematic for normally open and normally closed switches? Specifically the arrow direction.

The arrow on a switch points in the direction of activation... So a Normally Open Switch will point from an open position to a closed position.

Will students need to know how to draw a schematic incorporating SPDT, DPST or DPDT switches?

Yes- there could be questions on SPDT, DPST, DPDT in the drawing section. You can see examples in the extravaganza handout.

Will there be questions on calculating Resistance, Current or voltage based on the data given or circuit diagrams?

Possibly - but it would only require addition and subtraction.No complex calculations (as in resistance of a parallel circuit)

Will the competitor need to memorize the resistor color code?

Yes. This year there will be some questions on the resistor color code

Can students bring a pre-constructed circuit tester or a multimeter?

They will be told specifically what piece of equipment to use at each station. The "Multimeter" Station and the "Build a Circuit Tester" Station have been separate stations for many years now to avoid confusion, so they would not have the option to construct a meter or use a multimeter at the same station. The Circuit Tester is never pre-constructed, but would have to be built by the students at that station.

The Mystery Cards card could be either at the "Multimeter" Station (the students would be instructed to use the Multimeter to answer the questions at that station)and/orthe "Build a Circuit Tester" Station (the students would be instructed to Build a Circuit Tester to answer any questions at that station).

Below is the Heading on Station #4 and Station #5 from the 2015 County Event:

Station #4 – Meters: Multiple Choice

Use the Meter & the Materials in the box to answer the questions

Station #5 – Circuit Tester

If necessary, build a Circuit Tester to answer the questions at this station

When calculating resistance, will the kids be required to calculate the tolerance value?

Example  submitted with FAQ:
if the resistance of a resistor is 15, with a tolerance of 10%, will they need to identify the resistance as 13.5 - 16.5 Ohms, or will 15 +/- 10% be sufficient?

 

Supervisor's response:

 

Your question would be broken down into 2 parts on the exam

     What is the resistance of the resistor shown? Answer 15 W

     What is the tolerance of the resistor shown? Answer +/- 10%

Supervisor's response:

 

Your question would be broken down into 2 parts on the exam

     What is the resistance of the resistor shown? Answer 15 W

     What is the tolerance of the resistor shown? Answer +/- 10%

Will the resistors all be four band, or will it also include 5 band?

4 Band. 
I'm looking to see if the students understand the color code identification system.
The 5th band doesn't cover any new concepts and only adds some confusion for some students

Can you provide an example of a question they may have related to the resistor color code?

What is the resistance of the resistor shown below?

230 ohm resistor

     Answer: 230 Ω

What is the tolerance of the resistor shown above?

    Answer: +/- 2%

Will kids have to memorize resistor color codes?

I generally like to ease into a new topic. A color code chart will be at the station.

To maintain uniformity and fairness, the students are not allowed to bring any reference material or equipment. Everything they need will be provided.

My Charged-Up kit has a motor and propeller. Will motors be used at the tournament?

The motor and propeller are included in the Charged-Up Exploration Kits to add another interesting element to experiment with when learning about polarity and the effect of different voltages. (And it’s fun)
We WILL NOT be using a motor at the tournaments.
