Chemical Bonds

Chemical Bonds
  • Share your topic and “most powerful” web addresses and hyperlink sites on your blog. This gives you and your colleagues an open resource of ideas to draw from on 21st-century topics and tools.

The topic I chose is chemical bonding. I found several sites that can help students gain knowledge in the field of chemical bonding.
They are:

Chemical Bond Pauling


Glogster  EDU Chemical Bonding


NOVA Chemical Bonds Quiz- it is an interactive site that students can take quizzes on.




Interactive water molecule


The Concord Consortium Chemical Bond - Chemical Bonds Interactive download and use on internet or become a member and download the desktop. Can work by yourself or with a partner. Also comes with a quiz.


Youtube Downloader- software to download videos put on youtube.


Youtube videos- site with many videos related to chemical bonding and if students have access to a camera on their phone they can upload a video on you tube.

Quiz Chemical Bonds (Quia)


Quia- Site with many activities and tools


101 Science-many hyperlinks and tools that can be found such as Quia


Chem 4 kids- lots of information on chemical bonding


Think Quest- atomic structure and bonding information on Think Quest.




  • Explain how you expect these tools will help prepare your students to be 21st-century scientifically literate citizens.

Students will work in groups and convey information to their peers. Also, students will use the internet to collect information, and use power points to deliver their findings. Students will also be able to get a three dimensional view of what an atom looks like and when it bonds. After all, atoms are very tiny and an electron microscope is not on any high schools to buy list.

  • Describe at least one physical science activity you can plan around the use of one of these tools. Identify how this tool will help to engage students in the subject matter/topic of the activity.

Glogster EDU has a lot of information that students can access on chemical bonds. There are also visual java’s they can use to see what happens during bonding. It has so much information that I would have students break up into groups and have the different groups collect information from the different sites and present in front of the class. Students could prepare a power point showing the information they learned (Glogster EDU).


Also, a tool I liked that I can download onto my laptop is Chemical Bonds activity from the Concord Consortium. This tool can be used to give an actual representation of what happens when two element bond together. I can have students draw electron clouds for hydrogen and other elements and then have them predict what would happen to the clouds when they bonded with other elements. Then, students can check their work using the Chemical Bonds tool (The Concord Consortium Chemical Bond).

  • Share challenges you might face in integrating the use of this tool into your instruction.

Some of the challenges I will face are having computers for my students to use. I can reserve the library to use computers but the school district has firewalls to prevent certain websites from being accessed. I will just have to download the software onto my personal laptop and allow the students to use it on the promethean board as a whole group demonstration.

Try This for Heat Transfers

Try This for Heat Transfer

Place either beans, rice, or sand in a beaker. Heat them up and see how long they can hold their temperature doing the same experiment in heat transfers. I would expect for the solids to conduct heat slower, because convection happens in liquids and gases and pushes more vigorously against their surroundings (Tillery, Enger, & Ross, 2008). Therefore, the solid would stay hot longer.

Heat Transfer

I chose the basic materials that were losted for the heat transfer lab. The wool I could not find and had to go to the store to find it. I picked up some silk while I was there so I could use both items later on in a static electricity lab. The aluminum foil worked well. I guess it does help to trap in the heat. The thermometer that came with the kit was not a very good one but when you look around the house and can't find one, it is as good as it gets. The lab was simple and worked well with no problems. I would like to use this lab to reach the open inquiry level. How did your work out? Are there any things you would add to the experiment or change?
