Crest

For the past couple of Social Studies lessons, we've been making our own crests that represent us and our culture. This is the one I made:

The German and Croatian flags represent places I want to travel to when I'm older. The Scottish, Irish and Australian flags represent my heritage and where my ancestors originate from. The pencil is for my love for drawing. I drew a Roman Helmet because the main subject I want to take when I'm older is Classical studies. The keyboard and music notes represent my love for music (more specifically playing the piano), the F is the first letter of my family name and the parachute represents my dare devilish love for skydiving. I've been skydiving three times. I did my first skydive when I was 11 in Ashburton that was 12,500ft, then I did a 19,000ft skydive at Franz Josef at the end of 2016 and then another skydive last year in Ashburton at 13,000ft (I hope I get the chance to go again).

Filtering muddy water

LO1- Design and carry out an experiment
LO2: Explain separation via filtration

Goal: Our goal is to separate mud from water using only the equipment provided

Equipment used:

• Eight cotton balls
• Approximately 70 centimetres of string
• Paper towels
• One 1.5 Litre plastic bottle
• Two plastic cups
• A beaker filled with muddy water

           

Experiment method/design 1

In science, we are designing our own experiment to filter muddy water. My group and I made a filtering system that managed to get all of the mud out of the water. The first part of the filtration system consisted of a cotton ball wrapped in a paper towel. We tied it around the neck of the bottle after we put the muddy water in, then poured the water into a cup. This got rid of most of the mud. Then we put a cloth over another plastic cup and tied them together. We pushed down the centre of the cloth so that when we poured the water in it didn't spill over the side. This part of the filtration system took a while, because the water took a long time to filter through the cloth,but eventually all of the water was transferred into the cup. At this point, all of the mud was out but the water was still discoloured.

Results and conclusion for Experiment Design 1: My group and I didn't manage to filter the water so it was completely clear. We did however manage to get all of the mud and big clumps of dirt out of the water, which left the water slightly discoloured, but not as contaminated as it originally was.

                  

Here are some other designs and concepts for water filters that I found online. 

   

These are two diagrams showing how to make a home made water filtration system using the following materials/items: Rocks, coarse sand,fine sand, cloth, charcoal, water, string (or a rubber band) and a plastic bottle. 

Here are some links to sites that also shows you how to make a water filter:

Bacteria

Bacteria

What is Bacteria?

Bacteria are microscopic organisms that can only be

seen through microscopes. They are made up of only

one cell and are a king of unicellular organisms. They

are among some of the simplest single-celled organisms

on Earth.

What do Bacteria need to survive?

Like all living things, bacteria need food, water and a 

proper environment that is suited for their needs to live

and grow (suitable temperature and oxygen levels).

Food sources widely used by humans are especially 

vulnerable to bacterial growth because they are particularly 

nutritious. They also need moisture to grow. Bacteria do not 

survive very long on hard, cold surfaces that have no moisture. 

Food that is freeze-dried, is unable to support bacteria. Not all

bacteria is the same.Some species can thrive in oxygen-free 

conditions, where as others will immediately die without any 

oxygen present.
