Bubble Fun and Learning #15: Apple Bubble Science Activity

Although not as dramatic as Newton’s apple, this apple bubble science activity is sure fun! Kids like to play with food. After experimenting, they can eat.

edible bubble science with apples (5) labelThis activity is from Carla’s Bubble Science with Apples post at Preschool Powol Packets. I’ve seen a few other bubble activities using apples, but this is the only one that’s edible.

To do this simple science experiment, choose an apple with a fairly stable bottom so it can stand without rolling over. You will need to take the middle out of an apple, but do not go all the way through.

Use a grapefruit spoon or potato peeler just to scoop out the core and leave a small well. Place the apple on a saucer or in a shallow bowl.

Pour a spoon or two of juice into the apple. Carla used orange juice; we used some peach.

apple bubble science activity juiceWith a straw, kids blow into the juice to make bubbles. Ask your child about the bubbles. Are they very big? Did they float away or stay in the apple? Young children will mostly be interested in the blowing bubbles part so you may have to suggest the answers.

No matter how hard Little Sister blew, no bubbles but a few splatters.

Carla explains the difference is due to the proteins in the milk. “Milk has less surface tension than water because of these proteins.”

With the straw, the kids can taste and slurp up the bubbles. They made need to have more of this bubble solution as they blow towers around their apples. If they are super hungry, they can eat the apple and try the juice and milk in a small cup. Hmm, could that give the same result?

Children have curious minds. Isn’t this apple bubble science activity a fun way to feed their curiosity?

Play – Learn with Bubbles #6: Baking Soda and Vinegar Science Fun

Bubble, Bubble, Fizz, and Pop

Soap and water aren’t the only ingredients for bubbles. Another way is baking soda and vinegar science fun. Just a bit of makes lots of fun and learning.

play with baking soda and vinegarScoop some baking soda into a small bowl, fairly flat container, or even a clear plastic wine glass. Set this in another pan to catch the drips. Pour some vinegar into a second dish. Kids can use a spoon or an eyedropper to put a little vinegar onto the soda. They love to do this over and over again and watch as bubbles form and pop, getting high enough sometimes to spill over the edges. The bubbles hiss and pop adding exciting sound effects.

Soap bubbles shimmer with color. To a few containers of vinegar, add several drops of food coloring, one color for each bowl. Before squirting on the vinegar, ask kids what they think might happen. Will the bubbles be different colors? What will happen after the bubbles pop? Kids can then try adding the colored vinegar to the baking soda. The colors left behind seem quite vivid, depending on how many drops were in the vinegar.

Like blowing bubbles, this is a fun activity for kids of any age. There are some new words like fizz, hiss, and reaction. While young children are satisfied with the results, older kids might ask questions. Why did it do that? Where did the bubbles come from? Will it always do this? Kids are natural scientists. The explore and ask questions. All. The. Time.

Besides new words, questions, and explanations, there is also a sensory aspect. The soda feels very slippery on hands and fingers. The noises are very soft but exciting just the same and visually, the bubbles are fast and active. Vinegar has a bit of a smell, not particularly pleasant. The mixture isn’t at all tasty so if kids try it once is usually enough.

Is this variation of a bubble activity, baking soda and vinegar science fun, something your child has tried?

Planting Seeds Activity Your Child Can Do

The ground and weather may not be warm enough for outside planting, but how about planting inside? Here’s a planting seeds activity your child can do.

planting seeds activitySunflowers, beans, and corn are easy seeds to plant, plus they grow quickly too. Lima beans are nice big seeds. While planting seeds in soil is much easier for later transplanting, it’s really hard to wait even a few days for a sprout to poke up out of the ground. We can’t make soil invisible, but we can use a few different ways so kids can see the sprouts and roots start to grow.

planting seedsSoak a few seeds overnight in a bowl of water. A clear plastic glove or ziplock plastic bag can become a mini greenhouse for growing a seed. First, kids wet some paper towel or cotton balls and place in the bottom of a ziplock bag. A coffee filter will also work. Little hands may need to squeeze whatever you use to make sure it is just damp, not wet. Rest a seed on the paper or cotton, or tuck it in the folded coffee filter. Before closing the bag, give it a puff or two of air so it’s not flat. Then, hang the bag in a warm window. (We tried a penny to see if we could grow a money tree.)

Generally, sprouting takes only a few days. The seeds won’t need re-watering very often if at all. Condensation should build up a little on the inside of the bag. Once or perhaps twice a week for more water is usually enough. It’s so exciting to see roots come down and sprouts go up. Talk to your child about these different parts of the plant. Do they look the same? What’s different about them.

A cd case is another option for a planting seeds activity. So is a clear plastic cup, although it will require watering more often. If you saved any seeds from carving pumpkins, try a couple of these. Once the seed has sprouted, it can be carefully planted in a cup of dirt and set on a windowsill. In a few weeks, it may be warm enough to be transplanted outside.

Isn’t this simple planting seeds activity a great way to connect with nature and for kids to have a hands-on experience with science?

Star Wars Activities for Kids: Exploding Stars

Star Wars activities for kids do not need expensive toys or high-tech materials. Your kitchen cupboards likely have some items you can use for some science fun about stars. Yesterday, we looked at some pictures on the computer about stars and star dust. In one, there were gazillions of little white specks covering a dark … Continue reading Star Wars Activities for Kids: Exploding Stars

Dinosaur Float Sink Science Dinovember Fun

Real scientists estimate the mass (weight) of dinosaurs by floating scale models. We tried some dinosaur float sink science too. Not for checking on water displacement, just to see if they would float or sink. Water play is appealing for kids so with some warm water in the kitchen sink, Little Sister checked to see … Continue reading Dinosaur Float Sink Science Dinovember Fun

October Alphabet: W is for Wands & Science Magic for Kids

October is a fun time of the year for science magic for kids. There are some easy and simple science tricks that kids can do with ordinary household items. With a wave of a wand or a magic spell, wizards can make things float and sink. Partially fill a large bowl or container that you … Continue reading October Alphabet: W is for Wands & Science Magic for Kids

Q is for Questions: Kids Ask More Than 300 Questions A Day

Would it surprise you to know kids ask more than 300 questions a day? Certainly, there is enough time in a day for that many. I don’t know why anyone would ever dispute this number, they just haven’t been around a toddler or preschooler recently. Kids are curious: they just want to know. Some good … Continue reading Q is for Questions: Kids Ask More Than 300 Questions A Day

Colors can be used in so many different play activities, not just art. A few drops of food coloring and water made for some color and fizzy science fun. Set out some small containers with a bit of vinegar in each, and add a few drops of food coloring. The darker the solution the easier … Continue reading Colors of Childhood: Color and Fizzy Science Fun
