Hello everyone! This is a post on some science experiments I have done when babysitting or just for fun! Please follow my blog and share it with your friends. Now let’s experiment!
The supplies you will need for the first experiment are the following:
- Baking soda – about 2 tablespoons
- Dish soap (Dawn is best) – eye it, but no more than a tablespoon.
- Food coloring – one drop
- Vinegar – pour until foam starts to rise.
- Tupperware or testing tube
This is actually a very well-known experiment, called the “volcano”. I do add dish soap and food coloring to make a colorful foam eruption!
- Put the baking powder, dish soap,and food coloring in a tall Tupperware.
- Place the Tupperware, with baking soda mixture inside, in a dish.
- Pour vinegar in until foam starts to rise.
- Watch the eruption, and have fun!
The supplies needed for the second experiment are:
- Baking soda
- A balloon
- An empty water bottle (disposable)
This is another baking soda and vinegar experiment! These two ordinary items you probably have lying around the house, have an amazing reaction that is not only cool to watch, but it can blow up balloons!
- Take your empty water bottle and fill with the vinegar.
- Next fill your balloon with about a tablespoon of baking soda using a funnel (if you don’t have a funnel, just roll a piece of paper into the shape of a funnel).
- With out dumping any baking soda into the bottle, stretch the end of the balloon over the top of the water bottle.
- Lift the balloon up so that the soda falls out and into the vinegar.
- Watch it inflate!
- Tie off after its done inflating, and have fun playing with it or inflate more!
The third experiment’s supplies:
- Plate (dish, bowl, etc.)
- Food coloring
- Dish soap (again, Dawn is best)
This experiment I call “color explosion”. Colors just explode in every direction (on a plate, of course.) This is a super fun one to do with kids of all ages!
- Pour milk on a plate.
- Drop food coloring in the middle. Preferably one drop of red, yellow, and blue in a triangle shape close together.
- Dip the Q-tip in dawn soap.
- Touch the Q-tip in the middle of all the colors. (this is why I said put the colors close together. That way they all “explode” at the same time)
- Watch the colors go!
For the fourth experiment You will need:
- A flower (a carnation or rose would be a good choice)
- Food coloring
- Vase(s) or glass cup(s)
Again this is a pretty well-known experiment, but it looks so cool in the end and makes a great little gift!
For a rainbow flower:
- Fill four cups with water.
- Color the water by dropping some food coloring in them and mix. (do each cup a different color.)
- Cut the end of the flower’s stem in four sections.
- Put each section of the stem in a different cup.
- Let it sit for about 18 hours for the flower to be fully colored.
- That’s it! You could make more for a beautiful bouquet or just make one as a beautiful masterpiece!
For a solid colored flower:
- Fill a cup or vase with water.
- Drop some food coloring in and mix.
- Put the flower in and let it sit for 18 hours for a fully colored flower.
- That’s it! You could make more for a bouquet or just the one as a beautiful masterpiece!
Tip #1: Make more than one at the same time if you want a bouquet. That way you save time and have it all done at the same time!
Tip #2: Use glow in the dark food coloring to make the flower glow too!
This last experiment is a great one for science fairs! (I actually did this one for a science fair once.) Here is what you will need:
- Two lemons
- Copper wire
- Two pennies
- Two paper clips or Zinc/galvanized nails
- voltage meter
How to put it together:
- Roll the lemons back and forth once each.
- Using a knife, cut a penny-sized slit on one side of the lemon.
- On the other side, cut a paper clip-sized slit.
- Make the same cuts on the other lemon, except opposite.(see in pictures)
- Wrap one penny and one paper clip together with one piece of copper wire, and the other penny and paper clip with their own piece of wire.
- Place the pennies and paper clips in the lemons so that they look like the picture below. (It’s a little hard to explain, but a picture is worth a thousand words, right?!) The pennies and paper clips MUST NOT TOUCH each other!
- Touch the wires that are on the end of the lemons with the volt meter and record the number of volts you measure.
Tip: record the number of volts you get everyday for a week to see how long the lemons should sit for the most volts!
HERE is a video that explains why the lemons give electricity (it’s actually not in the lemons) if you are doing this for a science fair or project. (or if you just want to know or teach!) And HERE is a website that shows how and why it works.
Thank you for visiting my blog! I hope this was helpful and you that have just as much fun as I did when I did them!
Until next time,
