STEM Activity

The students had to create the tallest free-standing structure using one marshmallow, some string, some tape, and some spaghetti.

Coordinate Grids

So, I said I was going to post weekly, then school happened.  I need to set a reminder or something.  At any rate, I found this interactive game for Coordinate Grids.  This activity allows the user to plot points on the coordinate plane and to read the coordinates of a point plotted by the computer.

The Cartesian coordinate system was formalized by Rene Descartes in the 17th century to help visualize functions via plotting function values as ordered pairs. The story of how the system was developed is that Descartes was sick. As Rene' Descarte lay in bed sick, he saw a fly buzzing around on the ceiling. His ceiling was made of square tiles. As he watched, he realized that he could describe the position of the fly by the ceiling tile he was on. After this experience, he developed the Cartesian coordinate system in the 17th century to help visualize functions via plotting function values as ordered pairs. In this system a grid of evenly spaced horizontal and vertical lines is drawn, a center or "origin" is chosen, and horizontal and vertical scales are chosen.

FOCUS


I also saw this in the PLC on Facebook. Its not the most creative way to display the FOCUS; however, I just wanted to get it up prior the students arrival.  Too bad my clock doesn't work.  (smile)

BE Bulletin Board


All over Facebook in this PLC (Professional Learning Community) I belong to, there were so many teachers posting their "Be" Bulletin Boards.  Here is my rendition.

Let's hope that these positive words will continue to rub off on the students and they will keep positive words in their thoughts and mouths.

Art Work


This is a painting I did the day before I went back to work.  I used it as a way to relax before getting back to the grind of the Back-to-School business.  I painted everything freehand.  I have it placed in the window of my classroom door.

Welcome


Welcome back to school.  I painted this in early August 2015.  I actually saw this on Pinterest, so I decided to CASE it.

Family Life is Coming!

We will be beginning Family Life and Human Sexuality on April 27, 2015.  Have you returned the permission slip stating whether or not your child has permission to take the class?

We will be covering the following topics:

  • Friendships and Family
  • Puberty
  • Reproductive System (Male and Female) 
  • Teenage Pregnancy with respects to what resources are needed to have a baby
  • A final exam will be given at the end of the unit

The students will be separated by gender.  Ms. Sobecki will teach the girls and Ms. Fletcher will teach the boys.  The unit will take place for 10 days (2 weeks) at the end of the day.

Students that don't get permission will have an alternate health unit that consists of 10 assignments.

STEM Fair - Procedures - Due 3/23/15

  • The procedure should include all the steps that were followed in setting up the experiment AND collecting the data.
  • The procedures should be written in a clear, sequential manner so that someone else could follow the same steps to complete the experiment.
  • Numbering the steps is useful.

STEM Fair - Materials - Due 3/23/15

- Materials should include the equipment and supplies that were used to complete the experiment.

- Materials need to be listed in specific amounts and sizes for the ENTIRE experiment...including 3-5 trials.

Example:

One 500 mL beaker
3 plastic cups
One hand lens
Masking tape labeled A, B, and C

- Metric Units should be used.

STEM Fair - Variables - Due 3/23/15

There are 3 types of variables that must be considered

INDEPENDENT VARIABLE
  • There is only one Independent Variable
  • This is the one thing that will be changed on purpose to find out what effect it has on something else.
    • Are you changing the height, temperature, amount, liquid, etc.
  • Example, if you are testing whether or not water temperature has an effect on the dissolving time of Alka-Seltzer, then the Independent Variable will be the temperature of the water.

DEPENDENT VARIABLE
  • There is only one Dependent Variable
  • This is what factor is being observed or measured to see if it is affected by the change theIndependent Variable made.
    • What are you measuring and how?
  • In the example above, the Dependent Variable will be the dissolving time of the Alka-Seltzer.

CONTROLLED VARIABLES
  • All other materials in the experiment must remain exactly the same.
  • In the example above, the thermometer, Alka-Seltzer, type of water, cups, etc.

STEM Fair - Hypothesis/Prediction - Due 2/27/15

The Hypothesis/Prediction answers the QUESTION being investigated...a "because" statement must be included. The prediction is a reasonable guess about the outcome of the experiment and suggests a possible reason for this outcome.  Many times, the word hypothesis is used instead of prediction.  A hypothesis is a prediction that can be tested.  It should be based on prior knowledge, observations, or research and is accepted or rejected by the results of the investigation.  It should include the expected cause and effect in a given circumstance or situation.  Information from research or prior knowledge should be part of a hypothesis statement.

Class Dojo

There has been some miscommunications with regards to Class Dojo.  I just want to clarify that there is no alert that comes through when you send me a chat through Class Dojo.  Please don't think I am ignoring you.  I don't always keep Class Dojo open on my computer.

Therefore, if you would like immediate feedback, please email me at angeli.fletcher@pgcps.org.

STEM Fair - Question - Due 2/27/15

We have begun working on our STEM Fair projects.  So far we completed our QUESTION.

A STEM Fair project starts with a question.  For most students, a difficult part of STEM Fair is selecting a good question (topic).  It is important the question be one that is interesting to the student.  The question should be one that can lead to an experiment project where something is changed and the result is measured.

A good question...
  • must lead to an investigation (experiment) not a report, a demonstration or a model.  The question may ask about the effect of one thing upon another.
  • should be one from which you can collect data (ideally measurements or direct observations) rather than opinions.
  • should be specific rather than really broad
  • is one which the materials needed to experiment with are easy to find.
Examples of good questions:
  • How does temperature affect the bounce of a ball?
  • What type of conditions do mealworms prefer?
  • What shape of container will allow water to evaporate the quickest?
  • Does the drop height of an object affect the size of the crater it will make?
Examples of poor questions:
  • How do volcanoes erupt?  This questions is poor because it is a model, not an experiment, is too vague (broad), and will not involve data collection.
  • Why are there craters on the moon?  This question is not an experiment and would require only research, not scientific experimentation to answer.
  • How do bean plants grow?  This question is too broad and would require research rather than experimenting and collecting data.
