Mars | Home Chemistry

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 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.
Laser	Mars 2020's 7-foot-long robotic arm can move a lot like yours. It has a shoulder, elbow and wrist "joints" for maximum flexibility. The armlets the rover work as a human geologist would: by holding and using science tools with its "hand" or turret. The rover's own "hand tools" extract cores from rocks, take microscopic images and analyzes the elemental composition and mineral makeup of Martian rocks and soil.
Camera	The rover has several cameras focused on engineering and science tasks. Some help us land on Mars, while others serve as our “eyes” on the surface to drive around. We use others to do scientific observations and aid in the collection of samples. Also, there are: Engineering cameras: 9 Science cameras: 7 Entry, descent and landing cameras: 7 Total cameras: 23
Shovel, rock pick,drill	The rover body is called the warm electronics box, or "WEB" for short. As a car body, the rover body is a strong, outer layer that protects the rover's computer and electronics (which are basically the equivalent of the rover's brains and heart). The rover body thus keeps the rover's vital organs protected and temperature-controlled. The warm electronics box is closed on the top by a piece called the Rover Equipment Deck. The Rover Equipment Deck makes the rover like a convertible car, allowing a place for the rover mast and cameras to sit out in the Martian air, taking pictures with a clear view of the terrain as the rover travels.

2. In groups of 3 you will Design, Draw and Make a Mars Rover out of Lego Technics.
Materials:

Lego Technics
A4 paper
Pencil
Ruler
Eraser

The drawing and model must have:

6 wheels
1 camera
1 tool at the front than includes a shovel, pick and drill.
1 solar panel
1 laser that points at the ground

3. Mars Facts
Link: Facts

You will need to find out the following:

Fact	Earth	Mars
Picture of planet
Length of 1 year	365 days	687 days
Length of 1 day	23 hours 56 minutes	24 hours 37 minutes
Distance from the sun	149.6 million km	227.9 million km
Distance from Earth.	----	54.6 million km
Gravity:	9.807 m/s²	3.711 m/s²
Colour:	Blue and Green	Golden, Brown, Tan, and Reddish
Temperature	-88 to 57 C	-140 to 30 C
Rainfall	Average of 100cm	No Rainfall
Atmosphere	Nitrogen Oxygen Argon Others	Mostly carbon dioxide Some water vapour
Surface	510.1 million km²	144.8 million km²
Moons and names	Moon	Phobos Deimos

Conclusion: Write about what you have learnt.

I learnt heaps of new information from the tables. I really like learning about space, but I didn't know that much information. It was really fun and cool to blog about this topic. I mostly learnt about the parts of the Mars 2020 rover. I was astonished by the cameras of rover Mars 2020. They have 23 cameras!!

Mars 2020 rover has 23 cameras.
Mars 2020 rover has 6 wheels.

Emotions | Drama

For drama today, we had to answer some questions and describe them.

How do you feel today? Describe - share some vocabulary words for emotions

Today, I feel:

Happy and sad, because my friend, Christian is going to the Philippines. We are going to miss him.

Explain how you used your voice to show emotion in the puppet talk.

We had used a happy song.

For my puppet talk, I didn't talk because we were doing it with a song.

Share a video of your puppet talk.

Yet, we don't have a video of our puppet talk. I put the video as soon as possible (ASAP).

Make a positive comment on someone else’s blog

Plants | Home Chemistry

For science today, we are looking at plants. First of all, we started looking and finding out about dangerous plants in the world. We had looked at a video about carnivorous plants. (the link is below) We found out that plants eat insects because they need protein when they don't have sunlight.

AIM: TO LEARN ABOUT THE NATURE OF PLANTS

Carnivorous Plants

Plants fall into two categories:

1. Evergreen

2. Deciduous

Deciduous

Evergreen

Find three examples of each:

Evergreen:

1. Pine Tree

2. Eucalyptus Tree

3. Kauri

Deciduous;

1. Oak Tree

2. Maple Tree

3. Elm Tree

LEAVES

Simple Compound

Choose a leaf and do a leaf rubbing.

Example:
Plant type: Deciduous / Evergreen

Leaf type: Simple / Compound
Leaf colour: Green
Photo of leaf: Image result for simple leaf

Plant drawing: Image result for tree drawing
