XTLab 1-3 Measuring Decathlon Names __________________________
Hour _____
Rules In order to win the decathlon, your team must have the lowest point total of all the groups. You will be awarded points for each event. The first place team will be given 1 point, the second place team will receive 3 points, the third place team will receive 5 points, the fourth-7points, and the fifth place team will get 10 points. Each event will have different rules for winning, so pay close attention to verbal instructions.
EVENT 1 - Volume Conversions
Using the measuring cups, fill an ice cream pail with exactly 2 liters of tap water. You will have 10 minutes to complete the task with your group. At the end of the time each group will measure their liquid in a 2-liter volumetric flask. The team with the closest measurement will win this event. Points will be awarded based on how accurate each team is to 2 liters. Good luck!
EVENT 2- Javelin Throw
Each team must choose one player to be the javelin thrower. Teams will have two minutes to practice throwing the toothpick before making the final toss. The length of the toss will be measured in inches. Your team must convert this length in inches to centimeters and meters within five minutes. Whichever team has the longest throw and the CORRECT answer will be the winner. If your conversions are not correct, you cannot win the event!
EVENT 3- Finding Mass
Take the mass of an object that is given to you on a triple beam balance and convert the mass to lbs. Significant figures do count. The first team to do this properly will be the winner. Time limit is 5 minutes. Teams with correct answers will be given points accordingly.
EVENT 4- Dimensional Analysis
Your team will be given one minute to discuss the following challenge. Choose one player on your team to get any object in the classroom that is one dm in length and bring it to your awesome, wise and cool science teacher. The object must be as close as possible to 1 dm. Pushing, shoving, clawing and hair pulling are prohibited in this event. In order to win this event, your team must bring an object closest to 1 dm.
EVENT 5- Speed Conversion
In September of 2002, the world record for the 100-meter dash was broken. The new world record holder ran the race in 9.78 seconds. Convert this to miles per hour. First team to come up with the correct answer will be the winner of this event.
EVENT 6- Conversion Relay
Without talking, your group must convert 2.5km to miles using the following flow chart as a guide (km( m( cm(in(ft(mi). Each person must write down one conversion factor (equivalence statement). There should be five different conversion factors that your team should come up with. First team to finish will win the event. You must also get the correct answer.
EVENT 7- Standing Long Jump
The standing long jump will be measured in inches. One person from each group must be the designated jumper. The winning group will be the group that has the longest jump and has successfully converted the measurement from inches to micrometers.
EVENT 8- Heating a Liquid
Each group will fill a 400-mL beaker with 250mL of tap water. Using the ring stand, wire gauze (with white center) and the Bunsen burner, each group will begin to heat their liquid to 70 degrees Celsius. Raise your hand when you have successfully reached that temperature, and your teacher will come over and check to make sure your liquid is 70+ degrees. After this is done your group must convert this temperature to Kelvin degrees. The first group to complete the correct conversion will win this event. (Hint- the hottest part of a flame is the top of the inner blue flame - Bunsen burners will burn hotter when more oxygen is allowed in through the lower vents).
EVENT 9- Mass of an Elephant
If an African elephant has a mass of 2950 lbs, what is the elephants mass in kg and in newtons? The first team done with the correct conversions will be the winner.
Event 10- Final conversion (this could be you if you dont learn converting)
A physical science student has failed this lab and has decided to drop out of school. To make matters worse this student has a low paying job that pays only $5.50 per hour. The student works an average of 40 hours per week. How long will it take this unfortunate soul to make one million dollars? First group done will win this event and possibly the decathlon.
