Some of our students used their Science Fair projects to solve problems. What keeps flowers fresh the longest? We found out that flowers in distilled water with pennies was the answer. An out of the box solution that we will never forget.
Did you know that you can use a balloon as a speaker to amplify sound? Small sounds can make a big noise when you use a good sound conductor. Experiment with a balloon, compressed air and your own ears to find out how it works and the science behind it.
You will need: A Balloon
* Blow up the balloon.
Do you have too much candy in your house this time of year? Why not turn that candy into a science experiment.
Do you know that some chocolate bars float while others sink? Let your kids find out which candy will float.
Examples: 3 Musketeers bar, Kit Kat bar, marshmallows, etc.
The science behind it: Some candy has air trapped inside. It makes it possible for it to float on water.
Example: Take a 3 Musketeers bar. Poke a hole in it. Drop it in water. Do you see bubbles escaping?
Our bones are strong. Someone might get a broken arm if they fell out of a tree. Yet we can't bend our strong bones in half.
Bones are hard because they contain calcium. Calcium is a mineral contained in human and animal bones.
Try this experiment to see if we can bend a chicken bone in half.
You will need:
*Drumstick chicken bone
You will need to:
*Clean the chicken bone. Make sure all of the meat is gone.
*Put the bone in a jar. Pour enough vinegar to cover it.
*Put the lid on the jar for three days.
*After the third day, take the bone out of the vinegar.
*Try bending the bone. Does it feel rubbery? What happened?
Science behind the activity: The vinegar is a mild acid. It dissolves the calcium in the bone. This leaves the bone soft and rubbery.
One person who loves to talk about science is Bill Nye. He is a scientist, engineer, author, and inventor. He not only talks about science but he shows you why things work.
He has hosted several shows including “Bill Nye the Science Guy®," “The 100 Greatest Discoveries," and "Eyes of Nye."
You can visit his website to find:
*Science facts from episodes of his show
Sesame Street has a great addition to their website. They are highlighting science, technology, engineering, and math videos, games, and activities. Your kids can have fun learning with their favorite Sesame Street characters. Check out the following at: http://www.sesamestreet.org/stem :
*Experiments *Sink or Float
*Measurement *Properties of Matter
*Force and Motion *Engineering
Enjoy your STEM experience on Sesame Street!
Here is another great website to visit. Kids.gov has a science section.
* Science Games
* Science Videos
* Facts about Inventors and Scientists
* Science Activities, Projects, and Experiments
* About Science Jobs
* Main page: https://kids.usa.gov/science/index.shtml
Have fun and enjoy!
Do your kids love candy? You can turn a treat into a science or math lesson. Let's use M&Ms as an example.
Math (3rd-5th): Chart how many of each color M&M is in the bag. What is the most frequent color? Which color is in the least? Take an average. What percentage of the bag has red M&Ms.
Math (Pre-K - 2nd): Counting up to 10 or 50. Group M&Ms into groups of five or ten. How many groups of five are in a bag. Pick 10 M&Ms. Chart how many of each color M&M is in the group.
Science (3rd-5th): With adult supervision and approval - Do Some Colors of M&Ms Melt Faster than Others?
Science (Pre-K - 1st): M&M Survival - Background | Materials | Procedure
Science (all grade levels): Floating M&Ms Science Experiment
Enjoy your STEM activity and snack!
Are your children interested in weather? Here is a fun, science activity.
*Take an empty container.
*Fill it 3/4 of the way with water.
*Add shaving cream to the top to become your clouds.
*In a separate bowl, mix a few drops of blue food coloring with water.
*Use a dropper (small tube with suction bulb) to drop colored water on the clouds.
*Then watch the rain fall.
To learn more about the water cycle, kids can visit: http://www.sciencekids.co.nz/sciencefacts/weather/thewatercycle.html
Your children can also make a rain gauge to measure the amount of rain fall in a month.
Thanks to Crystal from Growing a Jeweled Rose for the science activity idea!
