electric circuit making

Last month, Ms Christine brought us to the science lab to make an electric circuit in different kinds of circuit according to the science workbook.Before we go in to the science lab, Ms Christine divide us into groups. Then, we go inside the science lab, then we made the circuits, we succeded. Then we go to class and do some worksheets. I think that this work is fun because i can try to make different kinds of circuits.

Making of parachute

Last month, ms Christine asked us to make a parachute. Unfortunately,every time we want to make it, many people/student didn't bring the materials, the materials needed is plastic bag, string and small and light object.(it can be a doll,etc).Then, ms Christine gave us a time to do it before dismissal time outside the classroom, I could not finish it, but I finished it at home,I only made the pattern at school.Many of my friends, finish them at their home too. It is fun to make a parachute, because we can make the parachute fly! But I think, there is also still some student that could finish it at the school. (there is no photo, because one of my friends that are supposed to send the picture didn't send the picture to me.)

The next day, we start to make the plastic cup telephone,it tooks time to make it, then, after me and my partner had finished,we still need to test it, if it works or not, because we need to fix it, if it didn't work.Finally, my plastic cup telephone is already done!for me, it is fun to make a plastic cup telephone!
