A  specially thank you to the City of Santa Clarita Public Works for lending us Mr. Capprarelli and Mr. Messih yesterday to discuss bridge building design with the students (and also mercilessly but scientifically) destroyed our bridges to find out how strong they were.


In a comment to this post, please share your thoughts (in a paragraph) on this project.

How did your group approach the design process?

What part(s) of the process did you enjoy the most?

What would you do differently if you had a chance to redesign?

Today, we'll be exploring different functions. We'll also be learning about function tables, also called input output charts, and you'll be posting your own functions as well.

Here's what you'll do:

Go to:

and practice finding the input, the output, and the rule.


Go to:

Explore the function machine program by choosing different functions, typing in a number, and observing the output.

After that, decide on a function, and then create an input output chart for it like we did in class.

On your blog, create a post called "Function Machine."

Inside the post, record the input output chart like this:

  x     y

 3      6

 7      10

10     13

Make sure you make your own function up. Make sure you record at least 3 pairs of input output. Don't tell us what your function is!

In the keywords section, use: dlindsay, function, input, output


Next week, you'll be able to look at other students' functions and try to guess what their function is (by posting your guess in a comment for their function).

Well, this morning was the morning of doom for 21 bridges built by 4th graders here at West Creek Elementary.

A  specially thank you to the City of Santa Clarita Public Works for lending us Mr. Capprarelli and Mrs. Gurrola to discuss bridge building design with the students (and also mercilessly but scientifically) destroyed our bridges to find out how strong they were.

Pick a place- anywhere you want. Write a paragraph describing your place, but don't tell us what place you have in mind.

Use details that you would SEE>HEAR>SMELL>TOUCH>TASTE in that setting. Remember that sights and sounds are probably the most important details to concentrate on, but if your place has a distinctive smell (like a bakery), those details could be very important too!

In a post, write clearly and descriptively, so your reader can guess exactly where your setting takes place.

For keywords use: dlindsay, writing, setting

Next, go find someone else's setting, and add a comment to it with your guess of where that setting takes place. Good luck!

It's time to make a word cloud!


A word cloud!


One of our vocabulary words this week, ENDURE, has the root, "dur" (lasting) in it.

Your mission:

Go to following link and find 15 words that contain "dur" and have definitions that have something to do with time.

Next, head to Wordle, click on "create," and type the root "dur" at least five times. Next, type the other 15 words you found and add them to your list. Generate a word cloud you like and take a screenshot of it. 

Next, upload and post your word cloud right here on the blog. Make a new post titled, "dur," and show us your cloud!

In this project, you'll be working with a group to research bridges and methods of bridge building. If you meet your checkpoints each day, you may also check out your bridge building materials in class and put together your team's bridge for our bridge competition.

Websites that you will need:

First, learn about the basics of bridges. Need help with bridge vocabulary?

Next, examine the forces that your design will have to deal with.

Thirdly, you might want to check out some of these other sites for more information (just to get an edge on your competition).

Lastly, it's on to researching your group's bridge.


Remember to break your project into separate tasks. Each person in your group should be accountable for making progress on their task. Your goal is to complete the presentation by the end of the week.

Here's an example of how you might decide to organize and order your work:


Create the five slides that you will use for your presentation. You don't need to add the information yet, just create the slides, decide on a color scheme, and title each slide appropriately. You will need these slides:

title, information, key facts, your group's bridge, references


Go back and fill in the information on the first three slides.

The title slide should have the name of the bridge your team is researching. It should also have the names of your group members (first name only). You should also have a picture of your bridge.

The information slide should tell where the bridge is located, when it was built, and who designed it. You should include at least two of the following pictures (bridge, designer, construction in progress, map/Google Earth screen-shot).

The key facts slide should explain what type of bridge your research subject is. If there are any other interesting facts (length, width, height, key features, etc.) include them on this slide. Try to include at least two more pictures of the following: sketch of this type of bridge, key features (you can reuse previous pictures with labels), other examples of this type of bridge.


Complete the last slide of your show. Include a list of all of the websites that you used (books as well). Include the title of the resource, the author, and date of publishing. On a website, sometimes it is difficult to figure out when the site was published. If you can't find a date, you do not have to include one. If you list a website, also list the website address (copy and paste this).


Go back and work on the fourth slide. This slide is about your project, the bridge your team is building. Include pictures of the bridge in progress, the name that your group is giving your bridge, what kind of bridge it is, and any sketches that you made in Tuxpaint before creating your bridge.


Go back and put the final touches on your slide. Make sure the information is accurate, easy to read, and free of errors. Make sure that you've included working links for your resources page. Now's the time to add fancy animations. If you do, make sure that they run by themselves. For this presentation, we are creating a self-running slide show. Make sure that each slide stays up long enough to read and understand all of the presented information.


Bridge Design Requirements:

Your overall design needs to span at least 20 inches. It also needs to be at least 5 inches wide and tall. You do not have to have a deck surface (road), but if there are supports above where the driving surface would be, they need to have at least 2 inches of clearance for cars to pass under.

Now that you've constructed your robot, it's time to create your display.

For your poster, you'll need to provide several items:

1) Robot Name (consider naming your robot based on its function)

2) The main function of your robot (what problem does it help remedy)

3) An engineering illustration (schematic) that shows how your robot works

Here's an example of a schematic

4) An explanation (ALPS style) of the problem you seek to remedy

  • What's the big idea?
  • What are some details?
  • How has this problem changed over time?
  • Are there any rules or laws associated with the problem?
  • What are the ethics involved?

Your team must explain the big idea and details of the problem. Then choose two more aspects to tackle. 

Go back to for some ideas.

If you use other websites for information, be sure to evaluate if they seem reliable. You'll need to list any sites you used for research on your poster as well.

This week you'll be creating a Jeopardy game for your vocabulary.

Use this link:

Don't lose your password, don't forget to save, and don't forget to bookmark the links for the working copy and playable copy of the game.

When you're finished, post the link to the playable copy of the game here.


You need to have all ten words from the section in your game at least once. You need to have four categories for your questions, and three clues in each category. You may add more words from previous sections if you have time.
