Task: How can you drop an egg from a height of 3 meters without breaking it?

Steps taken in solving the problem

Information gathering

What are the constraints?

The ground must be hard, no adding of sand

No use of Drones

No use of Parachutes.

Definition of problem : Drop an uncooked egg from 3m high onto hard ground without breaking it.

Brainstorming

The process of generating ideas to solve the problem

Identification of resources

Determine what is needed for EACH solution. e.g rubber bands, string , balloons etc.

Evaluation of pros and cons of multiple solutions

Compare each solution across similar criteria:

e.g. availability of resources, cost, how well each solution is expected to solve the problem, the complexity of the solution.

Determining most feasible solution.

After we have thoroughly evaluated the solutions, we choose one of them and implement it.

Definition: Finding and removing errors in your program is called debugging. 

While developing the solution to a program , it’s always a good practice to test your program by running it to ensure that the code runs as you intended. If it does not, you try to determine what caused the error and modify your code so that it’s fixed.

In class Demonstration

In the example below, we consider the task to be solved as part of a bigger program, however now, you would be working on the sprite movement:

Teacher discusses and demonstrates how  the program can be fixed.

Discussion

Even if you are confident that you have completed your program, you should test it to see that it works correctly , before releasing your programming project for use by it’s intended audience.

 

In class exercise and homework

Open the following scratch studio and try debugging the projects listed after the studio:

Blog is another word for weblog. A weblog is a website that is like a diary or journal. A blog can be private or public.[1]

Most people can create a blog and then write on that blog. Bloggers (a word for people who write on blogs) often write about their opinions and thoughts. A blog containing video material is called a video blog or video log, usually shortened to vlog.

When a person writes on a blog, what they write is in the form of a post, which is a single piece of writing on the blog. Posts often include links to other websites.

Blogs can have one or more writers. If they have more than one writer, they are often called community blogs, team blogs, or group blogs.[2]

Ways to Use a blog[3]

Teachers can use blogs to :

• publish assignments,
• resources and notes,
• keep students informed on class events, due dates, and content being covered.
•  improve students writing skills.

Students can use blogs to

• publish their writing and educate others on a particular topic.
• To keep track of extra-curricular groups and clubs e.g chess club

Updates:
