4 TANGRAM ROCKET

4.1 Objective

In this activity, you’ll create a large class rocket
made from geometric shapes or tangrams. When
the rocket is complete, you will color and cut out
your own set of tangrams and make your own
rocket.

4.2 Introduction

NASA launches spacecraft using rockets. The form of a rocket determines its
ability to fly. The nose cones are triangular (conical in three dimensions), the
body of a rocket is rectangular (cylindrical in three dimensions), and the fins
are triangular or rectangular. The unique shape and size of a rocket's nose cone,
body, and fins contribute to its capacity to deliver a spacecraft to its final
destination.

4.3 Materials

● Tangram Rocket Template
● Scissor
● Pencil
● Color Pencils

4.4 Instructions

1. Fill in the shapes at the bottom of one of the rocket designs with
different colors for each shape. If two shapes appear to be similar, use
the same color on both.

2. Now you will cut the shapes out of the paper, you may ask an adult for
help.

04- Stem Activity Computing Wonders

3. Use the shapes to build your rocket design! Start by filling in the rocket
that has interior lines. All the shapes must fit entirely inside the rocket’s
outline. Once your rocket is complete, show this to your Classmates.

Fig 4.3

4. For a bigger challenge, see if you can use the shapes to fill in the rocket
without interior lines, or build your own rocket without using a rocket
outline at all!

Fig 4.4

5. Can you build more designs using these shapes? Look at these pictures
of spacecraft, rovers , and landers, and try to recreate them with shapes.
What else can you build?

5.1 How to surf the Internet

The Internet can be a confusing place as it contains a lot of positive as well as
negative information. Many individuals can become victims of predators, online
frauds, Internet infections, and spyware if they do not have a safety net. With
such easy and free access to the Internet all across the world, many people have
taken use of it to take advantage of others.
However, there is no need to be afraid of the Internet. The Internet teaches,
positively impacts, and gives a creative outlet for today's youth when utilized
properly, with the proper precautions and knowledge.

Internet Safety Tips
Here are 5 internet safety tips:

1) Don’t give out personal information such as a home address, phone number
or school name

6.4 Debugging

What do you say when a program or block of code does not give you the right
results? You will say the program is incorrect or wrong. But in programming when
there is an issue in your code you say the code has errors. Now you know what
errors are let’s discuss what you call when you remove errors from your code.
The process of removing errors from your code is called debugging.

In this lesson you will be presented with a block of code that will have some
errors in it, your task is to remove the errors and get the desired result.

1. Click lesson 5 (Maze) level 1. (Fig 6.23)
