Los Reyes Magos de Oriente

1.- Finish the airplane experiment if you are not done.

2.- Find information about "Los tres Reyes Magos" and write their story in your blog. Add a picture.

3.- Write in your blog your letter to "Los tres Reyes Magos"

4.- Work on IXL



Airplanes experiment

1.- Visit the blog of the two partners after you in the class roster (alphabetical order) and write a coment about their blog.

2.- Post the communication of the airplane experiment in your blog following all the steps in the scientific method, be sure of explaining the research that you did, identify the variables of your experiment, include pictures of the experiment and of your graph. Also you have to explain the concepts of mean, median, mode and range. Ask me before to publish your post. You can find the pictures inside students public folder: airplanes experiment.

Bouncing balls experiment

If you are reading this is because you and your group is alredy done with the experiment. So now you have to present it in your blog. Here you can find all the Scientific Method Steps, follow them and do your best: (In red you can find special instructions or things that can help you). In your blog, write the title of every step and do the same than in your poster.
 

The Question

Your science fair project starts with a question. This might be based on an observation you have made or a particular topic that interests you. Think what you hope to discover during your investigation, what question would you like to answer? Your question needs to be about something you can measure and will typically start with words such as what, when, where, how or why.

Background Research

Talk to your science teacher and use resources such as books and the Internet to perform background research on your question. Gathering information now will help prepare you for the next step in the Scientific Method.

 

Just find, copy and paste the links of some research that talk about bouncing balls, rubber properties...

Hypothesis

Using your background research and current knowledge, make an educated guess that answers your question. Your hypothesis should be a simple statement that expresses what you think will happen.

 

Write the hypothesis that your group did, if you disagreed explain why

Experiment

Create a step by step procedure and conduct an experiment that tests your hypothesis. The experiment should be a fair test that changes only one variable at a time while keeping everything else the same. Repeat the experiment a number of times to ensure your original results weren’t an accident.

 

What is a Variable?

A "variable" is a word for a quantity or condition that can change. Variables can be continuous or they can be discrete. Continuous variables can have many values . For example, time is continuous and can have many values. Plant growth, amount of sunlight or amount of water flowing are all continuous variables. Discrete variables are ones that have a few, distinct values. Something can be either on or off, present or absent, or have only several countable possibilities. A kitchen light can be on or off or a person may have blue, brown, green or hazel eyes.

Independent Variable

An independent variable is a variable that you can control. One way to explain it to a child is that it is the variable that the child can change during the experiment. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant receives. He can put one plant near a window and another plant in a dark closet. 

Dependent Variable

A dependent variable is the variable that you observe and measure. You have no control over the dependent variable; you want to observe what happens to the dependent variable when you change the independent variable. For example, if the child is testing the effects of light on plant growth, how much the plant grows after some period of time would be the dependent variable. The child can measure how much the plant in the closet grows relative to how much the plant near the window grows.
Just explain the experiment, including materials, procedure, problems, variables...
 

Data

Collect data and record the progress of your experiment. Document your results with detailed measurements, descriptions and observations in the form of notes, journal entries, photos, charts and graphs.

 

Insert some of these pictures (copy, paste in your computer and later upload in your post) be sure to include the chart pictures. You can built your graph in these website: http://nces.ed.gov/nceskids/createagraph/

 

 

Observations

Describe the observations you made during your experiment. Include information that could have affected your results such as errors, environmental factors and unexpected surprises.

Like in your poster.

Conclusions

Analyze the data you collected and summarize your results in written form. Use your analysis to answer your original question, do the results of your experiment support or oppose your hypothesis?

Like in your poster.

Communication

Present your findings in an appropriate form, whether it’s a final report for a scientific journal, a poster for school or a display board for a science fair competition.

 

This post is your communication so you don't have to do any more.

Research 11/29/12

 

Hello students, this is your work for today:

 

1. Go to gmail account and send to me an email with your blog address mrgarciandpa2012@gmail.com

 

 

2. Write a post in your blog with your top ten science most interested topics. (The same that you did yesterday in you notebook) Title: My top ten Science Topics (order them from the most to the least interested for you)

 

3. New post, Title: Somos Cientificos! (We are Scientists!) Pick your three favourites topics and start doing a research about them. Find websites whit interesting information about your topics and copy the link, pictures, ideas...
