Fossilizating Facts
Introduction:
Dinosaurs left many footprints behind when they were living on earth millions of years ago.
Fossils of these imprints formed over time.
If the environment was just right the footprints filled with sediments and a fossil was eventually formed.
Let's speed up the process and make our own fossils!
Plaster Mixture:
Pour two and a half cups of plaster into a large plastic container.
Add one of water and mix together.
Keep the resulting mixture handy so you can pour it into the children's individual containers later.
Instructions:
Show the children a plaster of paris example.
Give each child an empty plastic container.
Get the children to put a quarter of cup of sand into the container.
Provide a small foot shaped object that will leave behind a good footprint shape (best prepared earlier) and tell the children to then press the footprint into the sand.
Mix up the plaster mixture and pour some into the children's containers.
If there are lids available for the containers, let the children then put their lids on and write their name on top.
Leave the fossil footprints to set and let the students take them home when finished.

Ka-Boombastic Countdown to Eruption
What you'll need:
Baking Soda (make sure it's not baking powder)
Vinegar
A container to hold everything and avoid a big mess!
Paper towels or a cloth (just in case)
Instructions:
Place some of the baking soda into your container.
Pour in some of the vinegar
Watch as the reaction takes place!
What's happening?
The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.
For extra effect you can make a realistic looking volcano. It takes some craft skills but it will make your vinegar and baking soda eruptions will look even more impressive!
