*** Making a fossil with your hand***

What is our theme?
Ocean - fossil/handprint out of sand. Liquid to solid

What is the lesson (overall Purpose): 
To recreate a fossil, or handprint of your own 
   
MA Guidelines/Standards:
PreK-PS1-4 (MA). Recognize through investigation that physical objects and materials can change under different circumstances. 

Learning Outcomes:

• explore ways materials can be changed by freezing, melting, dissolving (e.g., sugar crystals or gelatin in water); combining materials (e.g., earth + water = mud); and physical force (e.g., pushing, pulling, pounding, stretching materials such as play dough or clay).
• experiment with mixtures of common materials (e.g., flour, baking soda, cornstarch, water, salt, vinegar, food color), observe the results, then describe the experiments to others.

Materials

• A bin, container, or large bowl 
• 2 cups of sand 
• 1 ½ cups of all purpose flour 
• 1 cup of warm water 
• 1 ¼ cups of salt 
• Mixing spoon
• Roller 
• Paper plate  
• Knife 
• Shells, rock, gems, to decorate around your handprint 

Activity(Procedure)

1. Gather materials 
2. Pour sand, flour, and salt into bowl
3. Slowly add warm water 
4. Mix as you go with a large spoon 
5. Add water carefully to balance out the dough, if it feels too sticky add more flour or sand to balance it out 
6. Roll out an amount where your hand, and some shell decorations can fit. You can also place a plate over the dough and trace/cut out a circle shape 
7. Push hand into dough, then add shells/decorations. You can even write the date in the dough!
8. Let dry for 24-48 hours
9. Place in the garden, or house for decoration!
10. Instead of making a hand bring, you can also make a sand castle, or whatever you would like! Just leave enough time for sand to harden overnight so it will last forever!

Activity(wrap up)
In a couple months see if their hand grew, or compare it to the size of you hand. 

How do I know what my child is learning?(Assessment)
Ask them - “why did the sand become hard over night”
