Groovy Science
In
first grade we have been learning about the states of matter. The kids have
worked hard and learned a lot about solids, liquids, and gases. We were able to
do a lot of experiments during this unit, but this one in particular was a lot
of fun. We made LAVA BOTTLES!
You
start off with an empty water bottle and fill it 3/4 of the way with oil. Then
you add water to fill it up, leaving about an inch at the top. Next, you add 10
drops of food coloring. This is neat because the kids all expect the oil to
change color, but it does not.
Then comes the really fun part. You take an Alka
Seltzer tablet and break it into 4 pieces. You put 1 piece in at a time, and
watch the reaction. It looks just like a lava lamp!
We
had a lot of great conversation during this lesson about what was happening and
why. The students even got introduced to fractions in real life. They got to
take their lava bottles home along with 1 of the 4 pieces of the tablet. They
had to go home and show their parents and tell them what was happening.
