I am student teaching in a fifth grade classroom and I am scared to death of teaching science. We are talking about motion and physical science right now. To make it more scary, I have to teach it to both of the 5th grade classes. I was wondering if anyone has any ideas or suggestions about hands-on activities that can keep the children interested and take some of the pressure off of me. I would appreciate any and all comments. Thanks.

physical science vocabulary

Hi Lindsay,

I am just starting my phsyical science unit with my students this week. To introduce the vocabulary in our first chapter, I am doing the following "station" activity. I've never done this before, so you may want to tweak it to your class:

Words:

matter, mass, weight, physical properties, density, volume, mixture, solubility

Process:
At each "station," the students will have textbooks open to the correct page, and a hands-on investigation to help them create a meaning for each word. I have made a worksheet with specific questions on it for each station (the students will take the worksheet with them to each station and fill in the appropriate section as they go). I will first have the groups read their assigned sections (no more than 2 paragraphs)--timed (2 minutes or so). Then I will have them follow the directions on the worksheet to "investigate" each word. They will fill in the worksheet. Lastly, they will fill in their "vocabulary bank" with their definition for each word.

Materials for each station:

Matter--several classroom objects (paper, pens, desk, etc.)

Physical Properties--different colored and shaped balls

Mass--balance, stapler, paper clips

Weight--food scale, stapler

Volume--shoebox, rock, measuring cup, water, ruler (with centimeters)

Density--3 empty yogurt containers, rice, dried beans, nuts/bolts (fill each yogurt container to the top with each substance)

Mixture--box with markers, crayons, colored pencils mixed together (**I wanted to use sugar and iron filings...then seperate by magnet. I couldn't find iron filings in enough time).

Solubility--2 cups, water, ground black pepper, sugar, 2 spoons

Good luck with everything! :-)

P.S. I'm not quite sure how to attach things on this website, so I'll paste the worksheet that I've made. You're welcome to use it as you see fit. The formatting is off because of the cutting and pasting:

A book that might help...

Lindsay, See if your library has a book called "Roller Coaster Science." I loved working through a lot of this book with upper elem. kids. We learned centrifugal force, friction, potential and kinetic energy, pendulums ... all on the playground!
