Example of a STEM Fair Project

Please note: The STEM Fair Project listed below is just a model. It doesn't reflect actual data. It's just an example of all of the parts of one experiment except for the 3 required pictures of the actual experiment.

Question-  Which temperature of water ( hot, luke warm, or cold) will mix into red dye the fastest?

Hypothesis- I predict that red dye will mix into cold water the fastest because when my dad mixes Hershey's Syrup into cold milk, I can use a spoon to stir it and it mixes smoothly.

Variables:
Independent variable- different temperatures of water (hot, luke warm, cold)
Dependent variable- how fast red dye can mix
Controlled variables- same amount of each liquid, each liquid placed inside of the same type of container, same amount of drops of red dye placed into each liquid

Materials:
3                                    454 gram containers
3                                    500 ML of water
1 bottle                          of red dye
1                                    eye dropper
1 thermometer              using the Celsius side only because that is the METRIC units side
a microwave
timer or stop watch


Procedure-
1.    Gather all of your materials
2.    Label each container. Label first container HOT. Second container LUKE WARM. Third
       container COLD.
3.    Pour 500 ml of water into  your 454 gram container and place it in the microwave for 300 secs.
       This will make the water hot. Check the temperature with a thermometer to ensure that it is 68
       degrees C. If it's less than 68 degrees C, place it back into the microwave for another
       60  seconds and check the temperature again. If it's more than 68 degrees let it cool to the correct
       temperature. Once the correct temperature is achieved use the eye dropper to insert one drop
       of red dye into the hot water, and record in seconds, how long it took to mix into the hot water.
4.    Pour 500 ml of water into your 454 gram container and place it in the microwave for 60 secs.
       Check the temperature with the thermometer to ensure that it is 35 degrees C because that is my 
       measure of luke warm water. Add 30 more seconds in the microwave if the temperature is below
       35 degrees C. Use the thermometer to check the temperature. If it's more than 35 degrees C, let it
       cool till it reaches the correct temperature. Once the correct temperature is achieved, use the eye
       dropper to insert one drop of red dye into the luke warm water, and record in seconds, how long
       it took to mix into the luke warm water.
5.    Pour 500 ml of tap water from the cold side of a water faucet into your 454 gram container.
       Then, take the temperature of the tap water. If it is -15 degrees C, it is the correct temperature. If
       not, place it inside of the freezer for 900 seconds. Then, take it out and check the temperature
       again. If it's still not -15 degrees C, place the tap water in the freezer for another 900 seconds
       and check the temperature again. Repeat this step as many times as necessary to ensure that
       you have the correct temperature of water. Once you have achieved the correct temperature,
       use the eye dropper to insert one drop of red dye into the cold water, and record in seconds, how
       long it took to mix into the cold water.
6.    Repeat steps 2-4 at least two more times.
7.    Record all of the times you found.


Data Collection Tool:

                                       Effect of Temperature on Mixing into Red Dye

                                                   Trials Recorded in Seconds


Temperature of Water            Trial One         Trial Two       Trial Three          Mean Time
Hot water( 68 degrees C)           35 secs                  38 secs               36 secs          36.33 secs
Luke warm (35 degrees C)         42 secs                 55 secs               48 secs          48.33 secs
Cold        ( -15 degrees C)          95 secs                105 secs              99 secs          99.66 secs


Graph


Written Explanation:

The mean time for all of the trials was under 100 seconds. The longest time was red dye mixing into cold water, which was 99.66 seconds. The median time was red dye mixing into luke warm water, which was 48.33 seconds. The shortest time was red dye dissolving into hot water, which was  36.33 seconds. Since my means were on a wide spectrum, (ranging from 36.33 secs - 99.66 secs) I would say that the trend that I noticed is that the colder the water temperature was, the longer it took for the red dye to mix into the liquid.


Conclusion:


My hypothesis was incorrect. I predicted that the red dye would mix into cold water the fastest. However; red dye mixed into hot water the fastest ( within an average time of 36.33 seconds) followed by luke warm water (with an average time of 48.33 seconds.) Red dye actually mixed into cold water the slowest (with an average time of 99.66 seconds.) I didn't experience any difficulty while conducting this experiment. If, I were to do this experiment again, I would change the color of dye that I used, to see whether or not the temperature of the water really impacted how fast the dye mixed. Another thing that I would investigate would be the same topic of mixing red dye into liquids but not water, instead I would use milk, orange juice, lemonade and observe the rate of mixing. What I learned applies to the real world because if a mother wanted to host an Easter Egg Hunt for the neighborhood kids and she wanted to color the eggs, she could know that mixing the dye in hot water, will be faster than luke warm or cold water. Thus, she can save time.

Homework 11/12/14

Note to Parents,
Tonight, the Math homework is for your child to work on their First in Math-the skill sets section. I have stapled each child's first in math username and password on the first page of their agenda book. Please ensure that your child doesn't remove this card.

STEM Fair - The conclusion portion of the STEM Fair Journal is due on 11/14/2014. I displayed an example of a good conclusion online yesterday, 11/11/14. Please refer back to it as needed.

Parent Workshop- I will be hosting a parent workshop in my room, Room 43, on Friday November 14, 2014 at Paint Branch Elementary School. Please walk with your child's STEM Fair Journal. I will be explaining all of the required parts of the STEM Fair Project as well as answer any questions that you may have about your child's specific STEM Fair Project.

Tonight's Homework- Today, 11/12/14- I assigned Health homework to students in my homeroom today. We had testing this morning for the OLSAT. As a result of the morning long testing,  I didn't work with Mr Case's homeroom today, so they didn't receive the health homework for tonight. They will receive it tomorrow night. This week's health homework is to read pp 36-40 and answer questions 1-3 on page 40. Students were suppose to copy all of the homework mentioned on this site in their agenda books. Please ensure that your child is copying down their homework assignments every night in their agenda book. The agenda book looks like a giant calendar. Turn to the current date in your child's agenda book and you should see tonight's homework recorded every night.


Special Thanks to all of the parents that were able to attend yesterday's Parent Teacher Conference! Educating your child is a partnership between teachers and parents. Thanks for all of your support.

Homework 11/11/14

Tonight there is no Math homework. The last part of the STEM Fair Journal is due on 11/14/14. Please take this opportunity to work with your child on completing the CONCLUSION.

The conclusion tells what you learned about your topic after completing the experiment. It contains three parts. Use the question prompts below to organize your ideas. Then, join them together to create a paragraph, that will become your conclusion.

If you turn to page 27 of your child's STEM Fair Journal, you will see three questions that need to be answered about your project. Please answer them in complete sentences. Then join them together to create a paragraph (conclusion.)

Below are the question prompts that you will be answering this week.

Was my hypothesis/prediction correct or incorrect?
What is the answer to my question? Support the answer with data collected.
Were there any problems with the investigation or things that I would do differently?

Model Conclusion

My hypothesis was incorrect. I predicted that the red dye would mix into cold water the fastest. However; red dye mixed into hot water the fastest ( within an average time of 36.33 seconds) followed by luke warm water (with an average time of 48.33 seconds.) Red dye actually mixed into cold water the slowest (with an average time of 99.66 seconds.) I didn't experience any difficulty while conducting this experiment. If, I were to do this experiment again, I would change the color of dye that I used, to see whether or not the temperature of the water really impacted how fast the dye mixed.



Homework 11/10/14

Note to Parents
Parent Teacher Conferences are tomorrow 11/11/14. There is no school for students tomorrow. Mr Case, is going to be calling parents today, to confirm the scheduled times we created for our full day tomorrow.

Homework 11/5/14

Note to Parents

There will be no Math or Health homework this week. Health will be done in class this week. Since the data collection tool, graph, and written results are due on Friday, 11/7/14, I would love it if parents would take the next two days to ensure that their child is caught up in their STEM Fair Journal. Please refer to the example below to help you as you complete this week's required sections.

Data Collection Tool -Please read the information about this section on page 17 of your child's STEM Fair Journal.  Then, have your child use the designated space to design a chart or table on page 18 of their STEM Fair Journal.

You will need a place to write down your data as you conduct your trials and make your observations. Your collection tool can be a table, chart, or journal entry system to record your information. It should have the following items:

  • a title
  • labels to describe the columns or rows
  • space for repeated trials ( a minimum of three; more is better)
  • space for the calculation of the mean (average) of the data
  • all data is collected in METRIC units
If you are not collecting numerical data but rather making observations, you still need to design a chart or keep a journal in which you can record your detailed notes. This is most typical with projects that involve the growth or decay of something. If this section, data collection tool is done correctly, I will sign off in the "checked on" and "teacher" section of the box located on the bottom right hand corner of the page. In the next section below entitled, "Graphs" you will find an example of a data collection tool- this particular one is a data collection table.

Graphs

Once you have completed the data collection tool, you need to create a graph that represents your findings/data. First, read the information in your child's STEM Fair Journal on page 22 about Graphs. It tells which type of graph is most appropriate for each type of experiment. Please select the appropriate graph. You also need to find the mean of your data before graphing. Here's how to find the mean- add up all of your data sets then divide by the total number of data sets.  Take a look at the example below:


Model Question- Which temperature of water (hot, luke warm, or cold) mixes into red dye the fastest?

Below is a model of a Data Collection Tool, below it, is how to calculate the mean.


                                 Effect of Temperature on Mixing into Red Dye(title)

                                                   Trials Recorded in Seconds

Temperature of Water            Trial One         Trial Two       Trial Three          Mean Time
Hot water( 68 degrees C)           35 secs                  38 secs               36 secs          36.33 secs
Luke warm (35 degrees C)         42 secs                 55 secs               48 secs          48.33 secs
Cold        ( -15 degrees C)          95 secs                105 secs              99 secs          99.66 secs


How I calculated the mean for the above data         

To determine the mean for the hot water I added 35 + 38 + 36 = 109   Then I divided how many times I mixed red dye into hot water which was 3 times. 109 divided by 3 = 36.33 secs.

To determine the mean for the luke warm water I added 42 + 55 + 48= 145. Then I divided how many times I mixed red dye into luke warm water, which was 3 times. 145 divided by 3 = 48.33 secs.

To determine the mean for the cold water I added 95 + 105 + 99 = 299. Then I divided how many times I mixed red dye into cold water which was 3 times. 299 divided by 3 = 99.66 secs.

When you graph this information, you should ONLY graph the Mean data.

You can input your mean data into the following website and it will create a graph for you that you can print out and submit as your graph. Please ensure that you are selecting the appropriate graph for the type of experiment that you are conducting.

The website to help you create your graph:  http://nces.ed.gov/nceskids/createagraph/

Written Explanation

The last part that is due this week is the written explanation.  A written explanation gives a brief analysis of the data you collected in your table and displayed visually in your graph. It should be about one paragraph and summarize the data shown in the table and graph. It can include trends you noticed in the data, if any, but it should not be a conclusion. Please have your child complete the written explanation on page 26 of their STEM Fair Journal. You can read my comments when the STEM Fair Journal is returned to you to determine whether or not your written explanation was approved. I will complete the "checked on" and sign the "teacher" section located on the bottom right hand corner of that page.

Below is a model that matches the data that was presented above.

Written Explanation Model

The mean time for all of the trials was under 100 seconds. The longest time was red dye dissolving into cold water, which was 99.66 seconds. The shortest time was red dye dissolving into hot water, which was  36.33 seconds. Since my means were on a wide spectrum, (ranging from 36.33 secs - 99.66 secs) I would say that the trend that I noticed is the colder the water temperature was, the longer it took for the red dye to dissolve.

The explanation above summarizes the data by only mentioning the shortest and longest piece of the data. There is also a sentence that explains the trend that I noticed while analyzing the data. Your written explanation should have those elements as well.
