Challenge
A roller coaster, called the Dragon’s Breath, and has been designed for an amusement park. Your challenge is to take the roller coaster design and modify it for a select group of riders. For instance, you may decide that you will modify the roller coaster so that young children can experience the thrill of a roller coaster in a safe and non-threatening way. You may prefer to design the roller coaster for adults that are a bit squeamish about the big hills and sharp turns. They want to experience the thrill of a roller coaster ride, but are ready to pass on the death-defying action. On the other hand, you may choose to design a roller coaster for daredevils that are ready to handle any thrill you can provide. You may also wish to design a roller coaster for people who are physically challenged or visually impaired. However, in each situation, you must ensure that the roller coaster is safe and nobody will be in danger.
Criteria
Your design is based on whatever group you choose. Your design will have to meet certain criteria. All designs must have certain components including:
- at least two hills
- one horizontal curve or one loop.
In addition, you will have to provide evidence that the ride is safe. Safety data will include the height, speed, and acceleration of the roller coaster at three designated locations and a safe arrival in the cup at the end of the ride. Finally, you will have to calculate the work required to get the roller coaster rolling. You will present your design as both a model and a written report to a group of judges.
Team Work
Team work is required for this project. The team should decide on a roller coaster design that is specific for a select group of participants. There are other elements that should be included in a roller coaster model and presentation, such as theme, and presentation format or layout of all your data.
Self Reflection example
What is the most common element in the universe?
http://www.eduplace.com/kids/hmsc/activities/simulations/gr5/unite.html
Follow the directions. Before clicking on Step 3, create your teams hypothesis on which element is the most common. As a class vote on the most common element in the universe. Then complete the simulation.
As a team complete the following questions.
1. The simulation explains that since the densest part of Earth includes the crust, mantle, and core, and these are composed mainly of iron, oxygen, and silicon, these three elements are the most common on Earth. Why is density important to determine the most common elements on Earth?
2. How does the atomic number of the most common elements in the universe compare with those of less common elements? Give a hypothesis about why this might be so.
As a team make circle graphs on a poster size paper to compare the composition of the five different space objects shown in the simulation. Use your circle graphs to help others better understand the composition of the different space objects.
Create A Model
6.6.7, Describe the organization of the periodic table
6.6.9, Describe matter using the atomic model
Atom Foldable Instructions
You can choose any element you like, but remember, whichever one you choose you have to label it properly. GLO # 4, Quality Producer, GLO #1, Self Directer Learner.
For this example Carbon was chosen.
Draw your element card in the top right corner of your journal page, include the labels of the different parts.
Cutting and Gluing the Atom
Use the circle template Mrs. Togioka handed out.
First you cut the three largest circles out. Starting with the largest circle, fold it in half and glue the top half of the circle into your journal. Fold the second circle in half and using the crease from the largest circle as your bottom guide, glue that circle on top of the first circle, making sure it is centered. Repeat for the smallest circle. The smallest circle will be the nucleus and the 2 larger circles will be the shells or electron cloud.
Labeling the Atom
Get 3 different colored pencils. For example, red = protons, blue = neutrons, green = electrons. Create a key to identify the color and the particle it represents. For a Carbon atom you would draw 12 overlapping circles in the center of the nucleus, with 6 being red and 6 being blue (or whatever colors you choose for the protons and neutrons). The colors do not have to line up, and/or the circles may overlap.
On the outer circles, use the green color and place the electrons on the proper shell: 2 electrons on the 1st shell, and 4 on the 2nd. This is an example of a Carbon atom model.
Your finished model is due next class.
The Atom
8unit2pt3
Before opening the powerpoint, as a team see if you can answer these questions.
Can you name the charge of a proton?
What is the center of an atom called?
What particle circles the center of the atom?
After viewing the powerpoint review,
* write a summary on the structure of the atom using only 20 words.
* Use atom structure vocabulary words in your summary.
* We are going to count them.
* Good luck!!!
Science Fair, Science Fair, Science Fair
Science Fair Project is a great way to get families and students working together. As time nears to presentation and judging time everyone gets excited about how others view their work. Think about your project,
- is your project one that may benefit the world?
- can you discuss the main idea of your project with a judge with confidence?
- if someone was to read the design of your experiment could they copy your exact experiment?
- if you have a partner, are you both sharing the responsibility of the project?
- are you having fun with the project?
Doing a project is exciting, you just never know how its going to turn out. Have fun!!!
assignment # 6 Why did …
so many submarines fail to float, sink, and float again?
- were the submarines tested at home?
- were they built on the last day?
- were the materials wrong for the task?
- other reasons, like ….
- did students even understand density, buoyancy, gravity, mass, and matter?
- did they want to have a quality project?
