the cay

  My prediction is that they are deserted in the island and that the boy was washed out and was found by the black seaman and his companion. The boy and the sea work to together and help to keep each other alive and safe.

Convection and Conduction

Convection and Conduction are both types of heat transfer where energy is passed from hot to cold. When something passes through heat it will move faster, and as they move faster and faster they become more hotter. We can do this by Conduction energy to transfer through contact.  For 2 examples of good conductors  there would be like stove tops and pans because the stove top gets the heat from electricity and transfers the heat to the pan and to the food. And for Thermal conductor it can pass on heat to other objects. for convection they generate  heat without contact and for and example like heaters, they generate heat with using contact and as it does that the hot stuff rises and the cold stuff sink. Today we did a experiment by using  a tea bag  to allow it to rise and during the experiment We lit the tea bag to let it rise up. While it rose up we noticed it became less dense when it rose up and more dense when it sunk down the reason behind this is that  when it sunk down it become for compacted and when it went up it became faster and faster and transferd the energy to each other.

Chromatography

 Today me and my class will be doing an experiment involving chromatography. Chromatography is the process of separating  a mixture based on the pigments. and my hypothesis is  what colour it will turn out and how it will turn out. here is the method below. My outcome was very good because the colour pigments started to slowly come up to the paper.

1- Draw a line across the filter paper in pencil, 5cm from the bottom.

2- Draw a coloured dot in the centre of the line.

3- Measure out 10mL of water and place in the test tube.

4- Place the filter paper in the test tube and fold over the side. MAKE SURE THE PENCIL LINE/ DOT IS NOT IN THE WATER.

5- Wait for 5 minutes and observe the results

STEAM e-textiles

My groups plan is to gather and our resources first and plan our design with our admired choice. so far my groups big question is "how we can manufacture clothing without using to much resources." Our design is based on how fashion will look in 2050. In the bottom of this blog is our design and ideas on how it will look like.
