What are the 5 parts for? 
Link: Rovers 5 parts

Fill in the table below.

Name:	Purpose:
Wheels	The Mars 2020 rover has six wheels, each with its own individual motor. The two front and two rear wheels also have individual steering motors. This steering capability allows the vehicle to turn in place, a full 360 degrees. The four-wheel steering also allows the rover to swerve and curve, making arcing turns.
Solar Panel	The Mars 2020 rover requires electrical power to operate. Without power, the rover cannot move, use its science instruments, or communicate with Earth. Mars 2020 carries a radioisotope power system. This power system produces a dependable flow of electricity using the heat of plutonium's radioactive decay as its "fuel." The power source is called a "Multi-Mission Radioisotope Thermoelectric Generator" or MMRTG for short. The MMRTG converts heat from the natural radioactive decay of plutonium into electricity. This power system charges the rover's two primary batteries. The heat from the MMRTG is also used to keep the rover's tools and systems at their correct operating temperatures.

Revolution Tour

Revolution Tour

• What was the best thing/s about the tour?

We got the opportunity to go on stage if people got picked and this guy Reggie asked you some questions about bullying and he was the one that runs it.

He asked us a question about hope and what it means and people said hope means trust.

• What did I learn from the talk?

I learnt new things about bullying and how it isn't nice, so if you bully then people won't want to be your friend, so start being nice to others.

• How did I feel when we had the talk?

I felt really emotional because Reggie talked about him and it was really sad because he talked about how his mum turned into a prostitute for money to feed his brother and sister then she found out that she was pregnant with Reggie and she didn't want him so he got adopted to another family that wanted him.

That is why I felt that way because it is really sad to hear that your parents don't want you.

Something I am going to do is be nice. I am going to be nice by letting people join in and letting them share ideas  if they have them.

 

  

This is Reggie, he is famous for playing the saxophone

How to stay happy

What is mental Health?

Mental health is a condition when you can't handle your anger and other stuff

When I am Angry,Happy,Stressed I?

When I am angry etc. Be by myself for a bit

How do I deal with my emotions?

I get my emotions out by being by myself

Who is the best person to talk to?

My teacher the Cousneolor  and everyone else I can talk to

I am at home? Why?

I can talk to my mum because she has been around all my life and she is always by my side

I am at school? Why?

I can talk to my friends because I know they can keep a secret

Crystals

Aim: to learn about a saturated solution and how to make crystals.

Crystal video

Definition of solution: 

A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated: 

Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)

In groups of three you will make three different types of crystals and compare the results.

What crystals worked out best and why?:

Conclusion:

________________________________________________________________________

After watching the videos as a class, explain how the following crystals are formed:

Type	Explanation
Salt	It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions. One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world.
Sugar	As the water evaporates, the solution becomes more saturated and sugar molecules will continue to come out of the solution and collect on the seed crystals on the string. The rock candy crystals grow molecule by molecule.
Snowflakes	A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake.

CRYSTAL TYPES

AIM: TO LOOK AT THE 7 DIFFERENT TYPES OF CRYSTALS

Salt Crystals

Sugar Crystals

Borax Crystals

7 different crystal shapes

The 7 types of crystals

Type	Number of sides	2 examples	Image
Triclinic	7	Turquoise Rhodonite
Monoclinic	7	three axes unequal lengths
Orthombic	7	of or denoting a crystal system or three-dimensional geometrical arrangement having three unequal axes at right angles.
Trigonal	7	of or denoting a crystal system or three-dimensional geometrical arrangement having three equal axes separated by equal angles that are not right angles.
Hexagonal	7	of or denoting a crystal system or three-dimensional geometrical arrangement having three axes of equal length separated by 60° and a fourth axis of a different length at right angles to these
Cubic	7	A cube has six equal, square-shaped sides. Cubes also have eight vertices (corners) and twelve edges, all the same length. The angles in a cube are all right angles. Objects that are cube-shaped include building blocks and dice.
Tetragonal	7	In crystallography, the tetragonal crystal system is one of the 7 crystal systems. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).
