Moving maeb

 Maeb's Big Adventure

Goal:Guide Maeb through the colorful world of Roquetas del mar, dodging obstacles.

Controls:

   -Tap the space key: Flap maeb's wings and get her fly higher.

   -Release: Descend gently.

How to Play:

1. Take off: Tap the green flag to start her journey to Roquetas de mar!

2. Dodge Obstacles: Avoid the distotr maeb that appear in your path.

4. Stay Aloft: Don't let Maeb fly too high or too low. Find the perfect balance.

Tips:

Timing is Key: Practice your timing to flap at the right moment.

React Quickly: Be ready to dodge the maeb's that appear suddenly.

Have fun exploring the world with Maeb!

Scratch-Cacher game

 The lasts days I've been working on on this game.

https://scratch.mit.edu/projects/1078855887

This is my second game I've done this year. To play it you have to follow the following instructions:

-You have to move the bowl with the left and rigth arrow.

-The porpuose of the game is picking up as much os you can, when you catch a strar it gives you a point, and it is getting faster every time you pick up an item.

-When you pick a bomb it changes you score by minus 3. 

-You loose when your score is less than minus 5

This is all you have to know to play my game! Hope you like it.

Scratch- My frist Game!

 So my frist task to do this year was to make a scracth game! Here it is. You can play it!

https://scratch.mit.edu/projects/1087712251

Instructions:

So this is my first game, you are a dinusour, you have to dodge meteorites, when a meteorite get to the bottom it gets more faster they fall. You have three lives, if you get to 0, you loose. You have to use the rigth and left arrow to move yourself. Also when you loose a live it sounds asound, but if you dont loose that life and the meteorite gets to the ground it sounds a good sound.

Presentation 4 Year

               Hi!  Here I would be posting the exercises for Programing in 4Eso.

8. 3D printer process

                                 3D printing

Its a machine that can print figures in 3D form a computer design.

The first three-dimensional printer was created over 30 years ago, with the emergence of the stereolithography techique. With this method, three-dimensional object con be created from digital data.

The main parts:

 Extruder

    The part that takes the filament an deposist the exact amount.

    

7.Plastics

                                                               Plastics    

               

Many objects we use every day are made of plastic. Plastics are made of carbon and hydrogen. Thesee chains of macromolecules called polymers, which is another name for plastics. Polymers are composed pf smaller molecules called monomers.

Plastics can be divided into two general types according to their origin:

       -Natural Plastics: obtained directly from vegetables or animal sources. For example, latex and cellulose are produced by plants, and casein is a protein that is found in milk.

   -Synthetic plastics: Come from oil, Most plastics that we use today are synthetic.

Properties:

   1. Good insulator

   2. Combustible

   3. Ductiles and malleable

   4.High mechanical strength

   5. Great elasticity

   6. Flexible and light

   7. Great plasticity

   8. Most of them are recyclebles

   9. Resistant to corrosion

   10. They are very economic

Types of plastics

   Thermoplastics: you can heat them and mould them as many times as you want. Easy to recycle.

   Thermosettings: con only be heated and moulded once and the process cannot be repeated.

   Elastomers: they stretch a lot when applaying forces and can recover their original shape after suffering huge deformations.

Enviroment problems

  1- Crude oil is a finite resource, it’s going to run out one day.

  2- The process of turning crude oil into plastics uses a lot of energy.

  3- Most plastics are not biodegradable and are disposed in landfill sites, at best. They’re buried and take

hundreds of years to degrade. The decomposition of plastics pollutes and poisons the earth.

Plastic Manufacturing

    1-Injction: melted plastic is introduced into a mould. When the material cools down, it is remove. We can do Household conteiners, buckets...

   2-Extrusion: A rotation screw makes the plastic go through a hole. Once the plastic cools

down, we obtain long pieces of materials that can be cut. we can do tubes, water pipes...

   3-Blow: The material that is produce by extrusion, is introduced in a mould. Then the mould is filled with air and the plastic takes the shape of the mould. We do the bottles or some toys.

  4- Compresion: It is very useful for big simple thermosetting pieces like trays anf¡d containers. The plastic is shaped by the moulds on both sides.

   5- Vacuum: A sheet of thermoplastic is heated until it becomes soft ans then the air under the sheet is sucked out to create a vacuum. 

                                              Thermoplastics  

     There are 7 big types of thermoplastics 

1.-PET (polyethylene terephthalate)

It's a lightweight, recyclable plastic that is resist and to wear and tear. Has high transparency, it does not emit toxic substances, so it's suitable for holding food.

It is use to make bottles. It's also recyclable and can used to produce textile fibres to make clothes.

2.-HDPE (high-density polyethylene)

Is is opaque, inflexible and resistant to chemicals. It's non-toxic, so it's suitable for holding food.

 It is used for milk bottles, some bags, pipes and containers, among other objects.

3.- PVC (polyvinyl chloride)

Highly resistant to abrasion and impact.

It is used in pipes, cable insulation and profiles for doors and windows.

4.- LDP (low-density polyethylene)

It is soft and easily scratched. It is mainly used to make bags and packaging film.

5.- PP (polypropylene)

A plastic that is easy to model and dye. It is resistant to solvents and splintering.

It is used to make toys, folders, packing, healthcare equipment and house hold items.

6.- PS (polystyrene)

It is a very lightweight plastic that breaks easily. It is used to make packing for dairy products, stationery and toys.

Expanded polystyrene (Styrofoam) is widely used for packing, food packaging, food packaging and thermal insulation.

7.- Others

This is for other plastics that are mixtures of different resins, such as nylon, polycarbonate, or ABS (used in 3D printing).

The plastic materials in groups 1,2,4 and 5 are easily recyclable. Those in groups 3 and 6 can be recycled at specialized facilities. Those in group 7 are very difficult or imposible to recycle, depending on the resins used in them.
