Lockie Leonard's Diary

Dear diary. I am a terrible person. I didn't help my mom with the saving the river in the environment project, she had to do the work all by herself. I lied to Egg about doing the speech, too. He asked me to do it, i said i would practice the speech somewhere quiet. So i went to the windfarm, but instead of actually practicing i just went there because Dot wanted to meet me there. I betrayed my friend because of a girl and she didn't even show up. I waited and waited but she didn't come. I went back and everyone was gone. Egg hates me now.

Labbrapport Hertz

Jag jobbade med Soniya

Utförande: En person satte på ett antal Hertz när den andra inte var beredd för att se om den kunde höra. vi tog ner volymen tills vi inte kunde höra mer och skrev upp det i diagrammet.

Material: Dator, Hörlurar, Tonegenerator *

Slutsats: Låga ljud är mycket lättare att höra än höga ljud.

* Du behöver Firefox för att använda tonegenerator
