 Using displacement reaction  Think like scientist Group 1,3,5 Group 2 and 4 Questions to be answered 1. Can iron displace aluminum from aluminum oxide? explain 2. why is the thermite reaction useful for welding Rails? 3. The early blast furnace were in areas where there were supplies of iron ore and a lot of coal mining.  why do you think this was?

  Group 1 and 2 1. make a post for how metals react with Oxygen using information given below and arrange the metals based on there reactivity 2. Group 3 and 4  make a post for how metals react with water using information given below and arrange the metals based on there reactivity  3. Group 5 make a post for how metals react with water using information given below and arrange the metals based on there reactivity 

  Task: Arrange the elements of Metal in its ascending order

Transpiration virtual lab with 4 plants under 4 condition  A biology simulation demonstrating the rate of transpiration of 4 different plants under 1 varying conditions. Group1 and 2:   heater ,  Group 3:  fan , Group 4:  lamp,  group 5: control (click the option nothing) Steps: 1.     Click on Run to simulate   2.     view the amount of water transpired by each plant under assigned conditions. 3.     Data obtained is automatically recorded in the data table to the right. 4.     Repeat the experiment 2 times. 5.     Calculate the average value. 6. Write the average value on the teacher’s white board View the simulation .
