    I love your materials thank you for sharing them for free. :) Do know of a lab activity to do with covalent bonding? thanks again, Kelly


    • Liz LaRosa November 8, 2015 / 12:26 am

      Thank you :) Everything I have is posted, please check for future uodates. ~Liz


  2. Susanne September 14, 2015 / 1:50 am

    This is wonderful! I teach LLD self contained and it’s very hard to find anything that is broken down into something easy to understand (with lots of visuals!). I can’t wait to use this with the kids.


    • Liz LaRosa September 14, 2015 / 3:20 pm

      Thanks Susanne! I hope the kids enjoy the lessons :)


  3. Kim Meissner April 25, 2015 / 8:55 pm

    Hi Liz. I have been using your activities for years and I love how they keep my students so actively engaged. Can you describe what you use to complete the molecular models activities? Thanks.


    • Liz LaRosa April 25, 2015 / 9:28 pm

      Thanks Kim :) For the molecular models, I use a standard model kit with plastic colored atoms and wooden pegs or metal springs. I like to use them instead of gumdrops or marshmallows because it is more accurate when talking about bonding and the structure of the molecules. Sometimes I’ll make stations around the room with 3-4 molecules per station and index cards with the formulas on them. Each station would have the pieces needed for just those molecules. ie: H20, H2O2, NaOH, and KOH.

  4. Rachele Gentile March 16, 2015 / 5:58 pm

    Hi there. I started using your resources in class for my interactive science notebooks. For the ionic and covalent smart board activity, i still could not get the updated file to open properly (is it just me?) also, there is an ionic covalent notes page above but do you have something to go with it (a powerpoint, pdf file?) so i can show the students how to fill it out. thanks!


    • Liz LaRosa March 16, 2015 / 8:53 pm

      Hi Rachele, Sorry you are having trouble with the smart board file, do you have the notebook program to view the file on your computer? I would go to your tech department to see if they can help you with it. The notes that I have posted for I/C bonding go with that SB file, I don’t have other files for the notes. I use pennies as electrons and chalk in addition to the smart board file for students to practice bonding by drawing on their desks first then their notes.


  5. wnorton1159 February 24, 2015 / 11:37 pm

    I really love your site. I was wondering if you had the answers for the ionic & covalent bonding notes (the smartboard activity link does not work). I would appreciate any help for the worksheet or the updated link-Thanks!!


    • Liz LaRosa February 25, 2015 / 12:29 am

      Thank you! I updated the SmartBoard file link, they moved it but it is the same file. Sorry, but I do no have an answer key.


      • wnorton1159Wnorton1159 February 25, 2015 / 12:57 am

        Wonderful, I use a lot of your sheets for centers for my gifted 7th graders, doing the accelerated 9th grade physical science.

    Thank you for sharing your resources with us! I am really liking this new layout to your website! I LOVE of the resources you have created, especially for the chemistry unit. This is my 2nd year teaching, and your products have helped me a lot! When you do the BrainPOP Atomic Theory notes with your kids (didn’t use this last year), what do you do with the “What’s in the container?” portion?


    • Liz LaRosa February 17, 2015 / 2:26 am

      Thank you, congrats on making it through your first year and best of luck for the rest of this school year. For the ‘what’s in the container’ part of the lesson, which I use as an opening activity, I have a collection of new black socks filled with 3-4 small plastic toys in them (like GoGos/Crazy Bones). I double over the socks and use a rubber band to secure them closed so they can’t peak inside. The students try to figure out what is inside the socks by making indirect observations. I have also used a plastic container with toys in it, and cardboard boxes with assorted items in it. After several minutes, I let them see what is inside. Hope that helps :)


      • Seanagh Strebchuk February 19, 2015 / 6:23 pm

        Our entire school is unable to access the powerpoints, even after selecting read only. It is too bad, as these resources look pretty good!


      • Liz LaRosa February 19, 2015 / 11:43 pm

        Sorry to hear that, it sounds like a firewall or server issue if it was school wide. Have you tried accessing it from home? I checked on two different desktops (without logging into my page) and I was able to download, open, and view the ppts. ~Liz


  7. Brian February 5, 2015 / 3:35 pm

    Liz do you also have the answer key for the counting atoms worksheet? Great job..


    • Liz LaRosa February 5, 2015 / 5:24 pm

      No, sorry, that is a link to an outside resource.


  8. Carolyn January 30, 2015 / 2:09 am

    I am so glad you are still here – love your revised website. Thank you for making your resources available.


    • Liz LaRosa January 30, 2015 / 2:38 am

      I am loving this new layout, too, thanks! Happy to be back on the web and always happy to help :)


  9. Brian January 29, 2015 / 9:02 pm

    Great lab on balancing chemical equations…do you have the answer key for the pdf table 1 chemical equation problems!. Did this last year and amazed how students were able to pick this up! Laminating the formulas was a great idea.


    • Liz LaRosa January 29, 2015 / 10:36 pm

      Brian – Yes, I just posted it tonight, I had to reformat it and did not get a chance to when I posted the lab last night. Once the kids get the hang of it, most kids can balance the equations by sight and mental calculations. I tell them they can do the equations in any order they like once we do the first one together. Learning how to balance equations this way really helps them understand how it works. Liz


      • Brian January 30, 2015 / 12:29 pm

        I emphasized to them the importance of placing the cards on the table. I noticed a lot of students are so programmed to do things in their head. I found that those that were confused would try to think it instead of seeing the pattern visually. Once they figure it out visually it falls into place.


      • Liz LaRosa January 30, 2015 / 12:51 pm

        Agree, they used the cards for each problem and their abilities to solve the problems improved with each one.


  10. Nikki Sims January 24, 2015 / 7:04 pm

    Hi! I love the worksheet you created on finding the valance electrons. I tried to download the powerpoint slides that go along with the work sheet but it says something about the file being password protected. Is there another way that you can send it to me? I would love to use it in my 7th grade science classroom. Thanks!!


    • Liz LaRosa January 24, 2015 / 7:24 pm

      Hi Nikki, The power points are in a ‘read only’ format and can be used by anyone, they just can’t be saved and edited. A lot of the ppts I make are posted in places I don’t want them to be, for example on Teachers Pay Teachers or on other websites, so that is why they are in Read Only and can be used by accessing the link. Thank you for understanding. Liz


  11. Lisa January 21, 2015 / 6:47 pm

    I am glad this is still available- I love your style of teaching and it helped me get through my first few years of teaching at a low SES school with no science resources~ Thank you


    • Liz LaRosa January 22, 2015 / 2:43 am

      Lisa – that is so great to hear, we should all help each other since we all have the same goal, but we don’t all have the same resources or experiences. I am still learning from other teachers, too. Liz
