Melting Chocolate Experiment - Science Experiments for Kids - 1 views

    • Liz Dilts
       
      1.1.2 Characterize materials as solid or liquid, investigate their properties, record observations and explain the choices to others based on evidence (i.e., physical properties) 1.1.3 Experiment with simple methods for separating solids and liquids based on their physical properties. Differentiation: For gifted students, have them melt a solid in different ways (microwave, oven, stovetop, heat from sun).  Ask them to predict which will melt the fastest and then record their observations
  •  
    Using a chocolate bar or chocolate chips students will experiment with melting the chocolate in a microwave or over a stove.  Students will make predictions and will make observations about the solid turning into a liquid.  After they have made these observations they will put the chocolate back into the freezer and make predictions and observations about what happens next.

      1.1.2 Characterize materials as solid or liquid, investigate their properties, record observations and explain the choices to others based on evidence (i.e., physical properties). 1.1.3  Experiment with simple methods for separating solids and liquids based on their physical properties. Differentiation: Gifted students could do extended research on how people used to make butter in the pioneer days.  Have them note what was similar to how they made butter, and what was different.

    In this activity, students will shake heavy cream in a jar to watch a liquid turn into a solid-butter!  This is a very simple, yet exciting project that can then be eaten later!

    I remember doing this as a child in school. We spread it on saltine crackers because the teacher said that it needed a little salt to make it taste better.

Turn Salt Water into Drinking Water - 1 views

    • William Templeton
       
      This experiment can lead nicely into a social studies unit about the importance of water to human communities.  It could also be used as a starting point for a discussion of how scarcity affects price.

    Students learn how to separate salt from water in order to create drinking water from salt water.
