EXPERIMENTS for kids What better to do on a hot summerr day (or cold winter day) then doing experiments. Children need to be able to see how cause and effect works. Learning how to put different things together for a desired outcome helps little minds to expand. Declan and Reagan are the cutest little scientists. They also get to learn patience and cooperation. Buying the Stir It Up chemistry lab was the best idea. Different experiments are truly endless:) FamilyFun
When Reagan was 2 she started watching egg videos on her iPad (she had very limited screen time). We thought they were pretty weird but were also very harmless. As she got older she never stopped watching them and started getting her brother involved in her love of youtube (again limited screen time). Reagan came up one day and said she wanted to start a youtube channel of her own and we thought. Why not:) We didn’t want to limit it to just one thing like eggs so we thought FamilyFun would be perfect.
We have everything from reviews of the little tykes 7 foot first trampoline, to Skyfort 2, life like dolls from bradford exchange, and banzai waterpark. To shopkins happy places, fashems and mashems, more shopkins and more shopkins and more shopkins. Kinder eggs, and blind bags.
Playing at the beach, ymca. doing experiments, playing, playing and more playing. My kids love to smile and be happy and they want to share that with all of you. FamilyFun.
A clean 16 ounce plastic soda bottle
1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution, ask an adult to get this from a beauty supply store or hair salon)
1 Tablespoon (one packet) of dry yeast
3 Tablespoons of warm water
Liquid dish washing soap
NOTE: The foam will overflow from the bottle, so be sure to do this experiment on a washable surface, or place the bottle on a tray.
What to do
Hydrogen peroxide can irritate skin and eyes, so put on those safety goggles and ask an adult to carefully pour the hydrogen peroxide into the bottle.
Add 8 drops of your favorite food coloring into the bottle.
Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it.
In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds.
Now the adventure starts! Pour the yeast water mixture into the bottle (a funnel helps here) and watch the foaminess begin!
How does it work?
Foam is awesome! The foam you made is special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst (a helper) to remove the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots and lots of bubbles. Did you notice the bottle got warm. Your experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat! The foam produced is just water, soap, and oxygen so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain.
This experiment is sometimes called “Elephant’s Toothpaste” because it looks like toothpaste coming out of a tube, but don’t get the foam in your mouth!
Make it an experiment:
The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:
Does the amount of yeast change the amount of foam produced?
Does the experiment work as well if you add the dry yeast without mixing it with water?
Does the size of the bottle affect the amount of foam produced?
n experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies.
A child may carry out basic experiments to understand gravity, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and human sciences.
Experiments typically include controls, which are designed to minimize the effects of variables other than the single independent variable
