Testing our Rapunzel Creations

What materials did you choose for your build and why? Clay, water and cardboard. They were the easiest materials to use that we could find.

 

Here is a picture of my plan: I can’t.

 

Here is a picture of my first attempt at the building process: I can’t show you.

 

While you test:

 

What are you noticing? If she will survive and be free from the tower! And will not drown!

 

What things are working? Everything that was supposed to work. (Rapunzel leaving the tower living and the tower not falling apart.) 

 

What things are not working? Nothing, everything is working and nothing is falling  except for Rapunzel.

 

How will you tweak this? Make this better? (Be specific and detailed!)

We are going to make a zip line to the water so that she can land safely and leave the tower.

Do you need any new materials? If so, WHY? We need a string to make the zip line, a person in my group knows how to make it because he is the master of ziplines!

 

 

Sketch your new design with labels on a piece of paper. Make sure your drawing is detailed and specifically labeled.  I can’t show you.

 

Why will this new design work better than your first attempt? What is your evidence? It is more realistic and we planned it out more than we did with the old version. And we are making her be more sturdy and make her stand up.

 

Building a Insulator

This week in science, we worked in teams to create a water bottle insulator that kept the water inside the bottle the coldest for the longest amount of time. First, we planned what we would need, how we would build it, and sketched our first design. Next, we tested our design to see how well our insulator worked. Below you will see the results and how we will improve our first insulator to make it even better!

 

An insulator is something that slows heat down.

 

Here is a picture of our original design:

 

The materials we used were wool, metal, and rubber bands.

 

Results! What was the temperature of your water to begin with? After 15 minutes? After 35 minutes?

 

Time Temperature (in Fahrenheit)
0 minutes 54
After 15 minutes 57
After 35 minutes 61

 

 

The engineering process includes thinking about how to make your design better and re-building your product. The improvements that we will make to our insulator is wire. 

 

These changes will improve my insulator because metal is a good insulator.

 

 

 

New results:

 

Time Temperature (in Celsus)
0 minutes  7  degrees
After 15 minutes  10 degrees
After 35 minutes  11 degrees
