What is an example of a fun STEM activity that I can do with my 10 year old child?
One example of a fun STEM activity that you can do with your 10-year-old child is creating a simple volcano using baking soda and vinegar. Here are the steps to follow:

Materials:

- Baking soda
- Vinegar
- Food colouring (optional)
- Dish soap (optional)
- Container (such as a plastic bottle or small cardboard box)
- Small plastic cup or container
- Spoon

Instructions:

- Begin by preparing the lava mixture. In a small plastic cup or container, mix together some baking soda, food coloring (if desired), and a few drops of dish soap (if desired). The dish soap will help create foam and bubbles.
- Place the container (such as a plastic bottle or small cardboard box) on a flat surface that can get messy, such as a table or tray.
- Pour the lava mixture into the container.
- In a separate cup or container, pour some vinegar.
- Using a spoon, pour the vinegar into the container with the lava mixture.
- Watch as the vinegar and baking soda react, creating a foaming eruption that looks like a volcano!

This activity is a fun and engaging way to introduce your child to basic chemistry concepts, such as chemical reactions and acid-base reactions. It also allows for creativity and experimentation, as your child can adjust the amount of baking soda and vinegar used to create different eruption sizes and heights.
