Happy New Year Girl Scouts! With cold winter weather comes spending more time indoors. But time indoors doesn’t have to be boring! Try out these fun Winter Science Experiments to embrace the winter weather inside.
Create Fake Snow
You will need:
- A deep baking dish or foil baking dish
- 3 cups baking soda
- ½ cup white conditioner
- Mix ½ cup conditioner with 3 cups baking soda
- Mix until well blended and moldable texture is achieved
This project can be found on the Little Bins for Little Hands site, and is a great experiment in physics for girls of all ages. Girls will learn about Newton’s 3 laws of motion by creating force using the balloon, testing acceleration when different amounts of force are used, and finding that with our actions in this experiment there will be equal and opposite reaction.
You will need:
- 2 spoonful’s of baking soda
- 1 spoonful dish soap
- A few drops of food coloring of your choice (red makes a good lava color)
- 30 ml vinegar
- Small container
- Add everything except the vinegar to the container and stir well.
- Carefully shape a volcano around the container using snow – don’t forget to leave the opening of the volcano at the top!
- Add your vinegar through the opening and watch as the volcano erupts! For a larger eruption, add more dish soap, stir, then pour more vinegar.
How does this work?
Vinegar is an acid, and when mixed with baking soda (an alkali) they react together to neutralize each other. This reaction releases carbon dioxide, a gas, which is the bubbles that you see. The bubbles of gas make the dish soap bubble up to make a thick “lava”!
Reindeer Pipe Cleaner Circuit
Karyn at the Teach Beside Me blog shows readers how to create a reindeer circuit This electrical circuit project is perfect for the season, and teaches that an electrical circuit is made up of a source of electrical power, wires that can carry the current, and a light bulb. It is also a great way for girls to experiment with what happens when the circuit is intact versus broken.
Home Grown Crystals
You will need:
- Borax, sugar or salt
- Food coloring (optional)
- Pipe cleaners
- Wooden spoon
- Tall glass or mason jar
- First use your pipe cleaners to make shapes. Simple shapes work best, such as hearts, spirals or circles. Tie your shape to a wooden spoon that is longer than the opening to the glass or jar you will use.
- Pick whether you will use borax, sugar or salt.
- Boil a couple cups of water (WITH ADULT SUPERVISION). Add your crystal substance (borax, salt or sugar) until it dissolves. Then add more….and more….and more! You will be making this a supersaturated solution, which means that you will keep adding your substance and letting it dissolve. You will know that you have added enough when a small bit remains at the bottom of the pot/jar that will not dissolve.
- Once your supersaturated solution is ready, pour it carefully into the glass or jar, leaving about an inch at the top. If you would like to add color you can add a few drops of food coloring.
- Add your wooden spoon to the top of the glass/jar with the pipe cleaner shapes hanging in the solution. Make sure the shape does not touch the bottom of the container.
- Borax will make the crystals grow quickly, sugar takes about a week to fully form, and salt will take a few days.
This project is a great way to develop an experiment to see how the different substances react and what other variables such as sunlight or fans blowing air might do to the crystal growing process!
Don’t forget to document your experiments with pictures and send them in to us as a Mission Moment!
