My activity is something 90% of you already know about, but I didn't!! So, I am placing it here for the one or two who might try it because of reading here: :p
Monday morning: we are making fossils today because we didn't do it on Friday. Great activity for second grade bilingual and regular students. Bring in bag of sand, plaster of paris, dixie bowls, plastic plants or insects, water.
1. Students fill bowl with damp sand. Make a slight spherical indentation.
2. Students pick a plastic insect or plant or lizard and press into the damp sand. Remove carefully.
3. Mix 2 parts of plaster with 1 part of water and students mix in a small plastic cup. Mix until soupy (takes about 20 seconds only)
4. Students pour into the "mold" (sand with indentation)
5. Wait a few minutes and sprinkle dry sand on top
6. Let sit overnight
7. Next day students use brush to clean off sand and discover a fossil
Easy to do and fun for the students!!!
