TEKS & Objectives
7.6. Matter and energy. The student knows that matter has physical and chemical properties and can undergo physical and chemical changes. The student is expected to distinguish between physical and chemical changes in matter.
7.2.B design and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology
We will investigate the properties and purposes of materials.
I will experimentally test the properties of matter.
1. Watch video.
2. Review vocabulary of material properties.
Magnetism is a physical property of some metal objects that cause them to be attracted to magnets.
Texture is the way the surface of something feels (rough, smooth, fuzzy, sharp, slimy etc.)
Stretchiness A push is when you use force to move an object awayfrom you.
Absorbency is how well something can soak up a liquid like water.
“Absorbent and yellow and porous is he!”
3. Test different objects for magnetism.

4. Make a magnet track.
- Click the thumbnails below to download arrow tracks.
- Layer the paper over card stock, if preferred.
- Print car tokens. Cut out and tape a paperclip to the bottom of each.
- Use a magnet (or a stack of round craft magnets), positioned under the track, to guide your car to the end of the arrow.
- Race!
Speaking of magnetism…
I’m very pleased with my new refrigerator magnet.
So far I’ve got eight refrigerators.
5. “Tactile Textures”
