How to get to Mars

Aim: To learn about Mars exploration.

1. Rover facts 
2. Design, Draw and Make a Rover
3. Mars facts

1. Rover facts: 

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

Fill in the table below.

Name:	Purpose:
Wheels	The Mars Rover has six wheels and each of it has its own individual motor. The steering capability of the rover allows the rover to in spot, it turns a full 360 degrees. The four wheels steering also allows the rover to swerve and curve.
Solar Panel	The rover requires electrical power to operate if there's no power the rover would not operate. The rover carries a radioisotope system, this power produces electricity.
Laser	The super cam is located in the main head of the rover and it fires a laser at mineral targets that are beyond the reach of the rovers robotic arms.
Camera	There is a total of 23 cameras on the rover, 9 of the cameras are for engineering, 7 of the cameras are sciences cameras and 7 of them are landing, descending and entry cameras.
Shovel, rock pick,drill	These are called the sample handling, the rover will gather samples from the rocks and soil using its drill. The rover will then store the sample in tubes on the surface.

Carnivorous Plants

Plants fall into two categories:

1. Evergreen

2. Deciduous

Deciduous

Evergreen

Find three examples of each:

Evergreen: 

1. Pine Tree 

2. Magnolia Tree 

3. Kauri 

Deciduous;

1. Maple Trees 

2. Oak Tree

3.  Silver Birch 

LEAVES

Simple                                 Compound   

Activity: Choose a leaf and do a leaf rubbing. Once you have done the rubbing, cut it out and glue it on the tree.

Home Chemistry: What is that white powder?

Home Chemistry: What is that white powder?

Aim: To learn about the makeup of different white powders.



There are a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.

You will be given a small amount of 4 white powders on your cardboard. On the black cardboard using a magnifying glass look at the powders.

Look at them under your magnifying glass and record what you see. 

These are the four powders we will be using. Upload a photo of each powder. 

1.  Cornflour
2.  Baking Soda
3.  Salt
4.  Sugar 

Before you add the iodine, vinegar or water you will need to divide each powder into 3.

Materials

1.  Cardboard/Paper
2.  Magnifying Glass
3.  Pipette
4.  Sugar
5.  Salt
6.  Corn Flour
7. Baking Soda
8. Vinegar
9. Water
10.Iodine
Steps

1. Gather, paper, magnifying glass and Pipette. 
2. Split the paper into four sides. 
3. Then add some sugar, salt, cornflour and baking soda to each side.
4. Then using iodine add three drops to each one. - Examine closely what happens to use a magnifying glass for each one. 
5. Then using a pipette suck up some vinegar and add three drops to each one. 
6. Again using the pipette add three drops of water to each one and look closely on what happens. 

Findings:

Words to use: Absorbed, spread, frothed, fizzed, melted, blob,

	Sugar	Salt	Baking Soda	Cornflour
Appearance (White)	White	White	White	White
Grains (small, medium large)	Large	Large	Medium	Small
Smell (Strong, none)	None	None	None	Strong
Iodine	Absorbed	Spread slowly	Dried, looks like ear wax, solid	Dried onto the grain
Water	Absorbed	Absorbed	Dried	Spread out on grain
Vinegar	Absorb	Absorb	Fizz Up	Rolled Off and Dried

Write a conclusion about your findings. ( 4 plus sentences)
Use the Hexagon activity to give you some more ideas.

The sugar......
The Sugar is a white powder and has no smell. The grain is large and when
you add Iodine it absorbed it. When you added to water it absorbed it and when you add Vinegar it absorbed it. It also smelt very bad. 
The salt.....
The sugar is a white powder with no smell. The grains are quite large and if you add iodine it spread slowly and the colour disappeared lightly. If you add water it just absorbed it. When you add vinegar it slowly absorbed it. 
The Baking Soda......
The baking soda is a white powder and has no smell. It's grain's are medium sized. When you add iodine it dried up in and it looked it like ear wax. When you add water it dried. When you add vinegar it fizzed and dried after a few seconds. 
The cornflour.....
The cornflour is a white powder and has a strong smell. It has tiny grains. When you add iodine it dried into the grain. When you add water it spread out on the grain. Lastly, we added vinegar it rolled of the grain and dried. 


Do all the same experiments on the mystery white powder. What is it?

Baking Soda 

Crazy 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.

Borax Crystals

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Squares/triangles	Large	Hard
Sugar	Square/rectangle	Small	Hard
Salt	Cube	Medium	Hard

Conclusion: I learnt that they are all different shapes and sizes, and they are all different I also learnt that they are really easy to make. But they didn't quite finish but when I researched that's what I found out.

How is salt formed
How is sugar formed
How are snowflakes made 

Explain how the following crystals are formed:

Type	Explanation
Salt	While the ocean is full of a lot of salt. mining of salt involves pumping water below the earth's surface to dissolve the salt and create a salt brine. This brine is then pumped to the surface and evaporated to create salt.  Most table salt is made this way.
Sugar	Suger is made by sugar canes, It's processed and gets rid of all the bad stuff. You can also get sugar from sugarbeet. The sugar syrup gets boiled and then cooled.
Snowflakes	It's when water drops down and the air is so cold it freezes and the hydrogen forms a different shape each time.
