Purpose: A simple sensory game for exploring volcanoes and incorporating chemistry. You can use it as a fun sensory
activity for children or even dinosaurs!
material:
Air-dried clay
Red liquid watercolor (or food coloring)
Brown acrylic paint
Red acrylic paint
Oil painting brush
Squeeze bottle
Plastic tray
Transparent acrylic spray (optional)
baking soda
White vinegar
Old tag cap
Build a clay volcano
1. Give a handful of clay to the children and let them roll them into a ball. This is very useful for excellent motor skills, and it does provide them with a hands-on sensory experience.
2. Let them throw the ball high on the table. Snapped! This will create a cone-shaped volcano. Everyone's volcano looks a little different. We have taller thin models, larger base models, and so on. This is more about the interesting process, and they are learning along the way, rather than the appearance of the final product.
3. Upgrade: Re-use the old marker pen cap and place it on the ball with its large opening facing up. You can also use empty K cups or even mouthwash bottle caps.
4. Hand the child more clay blocks and press them into the small clumps around the marker cap. Remind them not to fill the hole at the top because this is where the volcano erupts.
5. After the mini volcano is formed, let it dry overnight. If the clay is really cold to the touch, it hasn't dried yet. Placing the volcano on a metal rack or in front of a fan will help improve airflow and speed up the drying process.
Painting volcano
1. After drying, let the children paint on the flat bottom (below) of the mini volcano with brown acrylic paint. Later in the scientific experiment of eruption, the acrylic paint will act as a barrier layer and protect the clay.
2. Continue to paint the volcano with brown acrylic paint until it is completely covered and allowed to dry. To ensure that there is no uncovered clay, you can spray all sides of the volcano with a clear acrylic spray. This part should be carried out by adults in a well-ventilated place.
3. After drying, let the children drip red acrylic paint from the top of the volcano. They can do this directly from the bottle or with a pipette. If the acrylic paint is too thick to drip, mix in a small amount of water until you get the right consistency. This became their own lava!
1. This is where the real fun begins. When all the paint is dry, place the mini volcano on a plastic container. Children can put a small spoonful of baking soda on the top of the volcano.
2. In a squeeze bottle, mix white vinegar and red liquid watercolor or food coloring.
3. You can talk about the chemical reaction between baking soda and vinegar. You can also discuss what is the location of lava or volcanoes all over the world. Which volcano is closest to your residence?
4. Let the children squeeze the vinegar mixture into the top of the volcano and watch the lava spurt out! Super exciting! !
