This 39-page project will help you bring a lesson about matter, floating and sinking, density, heat, graphing, and critical thinking to your classroom! It downloads as a PowerPoint file and contains editable pages so you can customize the lesson to meet your students' needs.
I teach this lesson to my 2nd grade students to address the following Texas standards:
- 2.5A - classify matter by physical property including shape, relative mass, relative temperature, texture, flexibility, and whether material is a solid or a liquid.
- 2.5B - compare changes in materials caused by heating and cooling.
- 2.5C - demonstrate that things can be done to materials to change their physical properties such as cutting, folding, sanding, and melting.
- 2.6A - investigate the effects on an object by increasing or decreasing amounts of light, heat, and sound energy.
Most people are familiar with the idea that putting Ivory soap in the microwave produces a fun new substance. This product not only addresses that concept and pulls in teaching pieces about density and graphing, it also provides all recording sheets (some of which are editable), a story to explain why the microwave has this effect on that soap, plenty of discussion questions, and more.
Here's a closer look at what is included in this pack:
- 5 pages of notes to you, the teacher, to give you hints and background information about the lesson
- 2 pages of potential answers to the [provided] discussion questions
- 6 pages of thorough lesson plans that include materials, essential questions, and detailed instructions
- 6 thought-provoking discussion questions (each displayed on a separate page and ready to be shown to the class)
- A prediction question prompt to display for students as they are working on their hypothesis
- 2 different full-page prediction recording sheets (perfect for printing for students and/or displaying as an example for your class)
- 4 different whole-class prediction graphs that are customizable and ready to be manipulated by your students
- 4 pages of fun science facts that help students think more critically about this lesson
- A 5-page story to display and read to your students to explain why Ivory soap floats
- A page to display that has the investigation question on it so your students always have their goal in mind and are thinking like scientists
- Example picture of what the end result should look like
- Two different 2/page recording sheets to cut in half and distribute -- perfect for gluing into composition-sized science notebooks
Required Materials for this Investigation:
-5 different kinds of bar soap (Ivory needs to be one, and the other 4 are recommended in the lesson plan but those brands don't necessarily matter that much) in varying amounts
-Paper towels or paper plates
-1 bucket or tub of water (any size, so long as it fits a bar of soap comfortably)
Although this lesson is messy, a tip for easier clean up is included, and the kids love it -- so it's totally worth it. :)
Just gather the supplies, start the PowerPoint show, and watch your kids gain a greater love for science!
** Although you could technically add text to any of the pages, pre-added, editable text is available on 4 pages.
