Topic 5: Saving energy and light bulbs

Aim - Make a circuit

Equipment - clip wires , battery , voltmeter , switch and lamp station

Method - Use clip wires and connect the clip wires to the battery and lamp station

also try to connect the switch to the lamp station.

Result - We tried using our method but it didn’t work so we got help from Mrs Shammer.

We got help from Mrs Shammer because we couldn't control the lamp station with the switch.

What is a light bulb made of ?

Two rods

Tungsten 

How hot is a light bulb ?

produces light has a led.

Led light bulbs can last 15 years of longer 

A led bulb has the same shape as a incandescent bulb.

Research about ~ Alexandra Dempsey

What does she do as a scientist ? She finds information about a place and she finds
out the best spots to find certain things. She also takes photos of things she finds interesting
and studies about it .

When she was young she loved going to the beach and finding things (shells, sea animals ,etc)
and she always wanted to know all about the things she found at the beach.She has also wanted
to be a marine biologist her whole life.

In high school she focused on math and science she loved to join classes that all involve science.

Her two people that she looks up to for  inspiration are Sylvia Earle and Dr Eugenie Clark.

How did she become a scientist ? She was working there as a volunteer and when they saw
her work and what she could do they offered her the job and she accepted it and that is how she
became a marine biologist

Her advice was that the more experience you have and the harder you work is how you
get your dream job .She said "the harder you work the more missions you go on".

What is rewarding for her as a scientist? She gets to have her dream job and she loves her job.

Next we watched a video in a article 

About students who had to do a experiment in Wellington 

The first group of students did an experiment to see if the size or weight changed the length of how
far the ball went.

The next group of students did an experiment to see which cloth absorbed the bacteria
called Salmonella the chux yellow cloth got rid of most of the bacteria on the egg.

Lastly the last student did an experiment to see if your personality changes you blood pressure.
He made about 70 people do a personality survey.
.(etc of a question How often do you hangout with your friends)
