Generating Germs

by

Bread and Potato Germ Experiment

On Friday, March 13th, Rooms 101, 102, 213, 214, and 215 did an experiment with bread. Room 102 also did an experiment with a potato. 

  1. I shook every students’ hand when they entered the classroom (I HAD washed my hands previously), but they didn’t know until afterward that I had put green glitter on my hand. The glitter represented the germs that were on my hands after I sneezed into them. We observed how many germs were spread throughout the class after touching so many people.
  2. Next we used bread to represent skin and touched the bread. We will compare these pieces of bread with the control – a piece that was untouched (I used gloves).
  3. We also came up with other things in school that people frequently touch, and then rubbed the “skin” (bread) on those items as well. I will post the daily update here. There were a few samples that the Day 1 photos did not come out, so those are starting with Day 2 in the galleries below.
  4. We also did a peeled potato as well.

Note: We did spend time washing our hands to make sure everyone was safe during this experiment.

Google Sites for Third Grade

Click here to go to Google Sites

Click here to go to the Google Sites Tutorial

Remember starting to work on a Google Site? We did this in the fall. Let’s use our extra time today to go back to Google Sites and continue to learn how to use it. When we started, some people may have chosen to do a site about themselves. Today I want you to start a new site on a science topic. Look below for examples. There are also some books on the bookshelf in the back – most on animals, but there are other ones as well. If your original site was on a science topic, you can continue to work on that one, or start a new one. 

  • Click on the Google Sites icon on the left and it will take you to a page that has your site and any others that you start. 
  • If you don’t remember how to create and edit your Google Site, then click the rocket on the left to go to the tutorial on Google Sites. 
  • Click on the Symbaloo link for some research sites (not all links on the Symbaloo board are research sites – only use it to research your topic).
Sketch out your topics in your science notebook. List the pages you want.
  • Pick a planet and create a site on that planet
  • Create a site about constellations or space
  • Information about NASA or space exploration
  • El Nino, tornadoes, earthquakes
  • Pick a cause that you want people to know about – global warming, deforestation, recycling, the “garbage patch”
  • “How to” site on something science-related
  • Create a site about an animal – or a group of animals (different types of insects for example)
  • Research a scientist or engineer
  • Health, nutrition, human body
  • Science or engineering careers
  • A habitat (desert, for example)
  • A National Park 
  • Animals that live in San Diego (not pets)
