Why students need more 'math talk'

Math and Science go together like peanut butter and jelly!

Most math classrooms feature a teacher lecturing and students quietly working on problems. But research shows that a different approach would lead to better results.

Here is some great ideas from my friend Dr. Cindy Smith I know what I am going to do soon! Lots of great green veggies love to get started in late winter so they can be ready for spring. Most LOVE the cooler weather.

How do MowCow owners keep their thumbs green during dreary, drizzly winter days? Watch and listen🌱🌱🌾🦋🌻

ok so I am re-posting this. PWC has NOT called anything, this was from years ago. BUT the activity is still super fun to do. Just remember do not use food coloring, use a koolaid, or other natural coloring agent. Food coloring has an additive that WON'T freeze, and lets face it whats the fun in that?

Prince William County Schools have called for a 2 hour delay due to -0 temperatures. SOOOO that means fun for the morning right! Tonight you can make a few water balloons with the kids (though some may already be asleep) and put them outside to freeze. To color them use koolade or other colored drink mix. DO NOT use food coloring as it has a glycol in it and it won't freeze. In the morning see if they have frozen. It will depend on how big you made them, but you can leave them longer to freeze as it is not supposed to be above freezing all morning. Do all liquids freeze the same way? Try freezing milk, or juice and see what happens. Have fun and stay safe and warm. Oh and get your bubbles ready for tomorrow mornings post.

This is going to be so much fun to try!! If you do it, and get pictures, or videos please share. My friend Cindy wants to see them too! Also I will be posting a video of hot water being tossed into the frigid air tomorrow. Asking for your best hypothesis.. what will happen when I toss boiling water into sub freezing air? Post your thoughts!

Fun Snow day activity

Fun Snow day activity

Everyday Science is all about YEAST!
Yeast is an amazing ingredient in our kitchen. It makes our bread bubbly, and light, and it makes some adult drinks fizzy. Yeast is actually a fungus. Yep like a mushroom. It feeds on sugar and gives off the gas carbon dioxide, just like us we breathe out carbon dioxide. But yeast is fun to play with too.

For this experiment you will need one package of yeast (more if you like) Measure about 1 tsp of yeast into a cup, then add ½ cup of very warm water to it. Watch what happens. The yeast will wake up and start to get active with the warm water. Now add about 1 tsp of sugar to the bowl and let it sit for about 5 minutes. The bowl will be full of bubbles! The yeast is feeding off the sugar and breathing (or farting if you like) the carbon dioxide. It uses the oxygen in the water to help get the bubbles going. To see it a little better add a drop of soap to the solution in the bowl. The soap solution will trap the bubbles and make even more bubbles that are easier to see, since often the bubbles given off by just the yeast escape into the air and we don’t see them.

OK now for some real fun. Do this in the sink or in a large bowl as it will be a little messier! Put another tsp of yeast in a cup, or something that can easily be poured set aside to wake up. Get some hydrogen peroxide, from the medicine cabinet. Put about ½ cup of hydrogen peroxide into a recycled water bottle (small is better for maximum effect). To the bottle and hydrogen peroxide add a few drops of liquid soap. Put the bottle in the larger bowl or sink. Then quickly but carefully pour in the yeast solution into the bottle and stand back! What is going on? Hydrogen peroxide H2O2 has an extra oxygen than normal water H2O, and the yeast gets so excited with all the extra oxygen that it doubles the amount of bubbles it creates and FAST. Because the small water bottle can’t contain it, it gets forced out of the top and wow! Yeast explosion!! Experiment with the amounts and let us know how it worked for you. DANGER!!! Hydrogen peroxide is toxic if swallowed, DO NOT put this in your mouth. And it tastes really bad too. Yuck.
For a colorful foam, add a few drops of food coloring to it.

Powwow

This is so cool. The science teacher in me is going nuts with all sorts of science lessons in this. It's physics in sound, motion, speed, but it is also just a very relaxing sound that brings out the awe in the ART of it as well. Reminds of a wonderful art exhibit I saw in Palo Alto with pebbles in a frozen block of water that would melt and drop pebbles into large urns, or on top of bamboo poles. I love the combo of Art and Science STEAM at it's best!

So you wonder how an earthquake can do so much damage. Well this is one way.

Liquefaction in action - Soil liquefaction, also called earthquake liquefaction, ground failure or loss of strength that causes otherwise solid soil to behave temporarily as a viscous liquid. The phenomenon occurs in water-saturated unconsolidated soils affected by seismic S waves (secondary waves), which cause ground vibrations during earthquakes.

Although earthquake shock is the best known cause of liquefaction, certain construction practices, including blasting and soil compaction and vibroflotation (which uses a vibrating probe to change the grain structure of the surrounding soil), produce this phenomenon intentionally.

Poorly drained fine-grained soils such as sandy, silty, and gravelly soils are the most susceptible to liquefaction.

Make Your Own Marshmallows
Next time you get set to make hot cocoa on a chill winter afternoon, consider this: if you make your own marshmallows, you can mix up some very interesting third grade chemistry lessons while you're at it!

Here's the deal: marshmallows depend on gelatin, a common household ingredient. But for third grade scientists, gelatin is also a great way to demonstrate how molecules can rearrange to change matter from one state to another. Follow the directions below to see just what can happen when gelatin meets some sugar, cornstarch, and heat.
What You Need:
2 envelopes of plain, unflavored gelatin
½ cup cold water
1 cup light corn syrup
½ cup granulated sugar
1/3 cup cornstarch
½ teaspoon vanilla
1/3 cup confectioner's sugar

What You Do:
1. In a small bowl, combine the cornstarch and confectioner's sugar. Grease the sides of a 9” square baking pan, and place a sheet of parchment paper or wax paper, cut to size, along the bottom and then grease that, too. Use a bit of the cornstarch mixture to dust the bottom and sides of the greased pan.
2. Now place the contents of the two packets of gelatin into a small saucepan, and mix in the ½ cup of cold water. Let it stand for one minute, and then cook and stir over low heat until the gelatin is fully dissolved. (What's happening? The water has spread out the special protein fibers that make up the gelatin, and the heat has dissolved their original bonds. That's why the gelatin seems to “dissolve” into the water.)
3. Now pull out a mixing bowl, and blend the granulated sugar, corn syrup, and vanilla. Add the gelatin mixture, and beat the whole mixture thoroughly—for up to 12-15 minutes—with an electric mixer. Watch the mix become thick and creamy. Pour it into the greased baking pan, and let it stand at room temperature for at least 4 hours. (What happens: the protein bonds will begin to re-form as the gelatin cools…but now it's mixed with other ingredients, so it will hold them together, too, in classic “marshmallow” texture.
4. After four hours, or overnight, place the white sheet on a cutting board which has been sprinkled with the remaining cornstarch-sugar mixture. Cut into cubes with a knife (hint: it's helpful to dip the knife into hot water first, to keep marshmallow goo from sticking!)
5. Roll the cut-up marshmallows in the cornstarch mixture to keep them dry to the touch…and then devour!

Make your own fun salt crystals. You can use just about any kind of salt. Alum, table salt, epsom salt, even using borax detergent will work. Don't forget about SUGAR Crystals you can eat! (sugar take a long time to form though) There is no perfect recipe.. But try this. Start with a large pot, add a cup of water and start boiling it. Add salt.. then more salt, and more salt.. (or sugar) until you add so much salt it stops dissolving and sinks to the bottom. At that point you have saturated the solution! Turn off the heat and let it cool just a little bit. Then take out a string, yarn, or pipe cleaner and get it wet. Roll it in the salt (or sugar) that use used to put in the solution. This gives new crystals something to attach to. Pour the solution into a GLASS jar, or cup. See through is much better so you can watch as crystals start to form. It must be glass as this is VERY VERY HOT! Then add your string to the solution, tying one end over a spoon or pencil to let it hang down. Sit back and wait. It can take a few days to start showing crystals. You can speed this up by "spilling" a little bit onto a paper plate, or dark paper. They won't be large crystals, but they will dry out much quicker and fun to watch grow.

Make some snowflakes to keep inside. Take a coffee filter and fold in half. (a piece of paper cut into a large circle will also work). Once in half, fold into thirds. This will give you 6 sides. Start cutting small shapes out of the edges of the wedge you folded. By keeping it folded, you will be creating a snowflake that has 6 symmetrical sides. Snowflakes are very symmetrical. Experiment with triangles, hearts, half circles, cut the tops off, or the ends off. Just have fun. If you like you can always color the snowflake using water color markers then add water and watch the color move through the coffee filter.

Did you know all snowflakes have 6 sides.. Though this graphic shows some shapes as a column, what we think of a snow flake is always 6 sided. The different types of shapes that are formed, have a lot to do with temperature and how much water is in the air! What are seeing at home today? To capture some snowflakes, put some dark paper in the freezer so it gets very cold. Then take it out and lay it flat to catch some snow flakes. Then see if you can see them before they melt. If you bring them inside though.. be sure to have a towel handy!

oh no... SNOW!!!! and I didn't plan something fun for you to do today. I will get on it and post ASAP but for now, snuggle those kiddos, make some hot cocoa, and watch some cartoons together.

There are a lot of science kit delivery companies out there. How to choose just one? I wish I knew. Each post looks so exciting, but I do know that it isn't always as easy as it looks. So please shop around, read the recommendations, and find out from others what they think. Some things to think about, does it come fully complete or do you need to supply some stuff. Age appropriateness, level of parent involvement needed, are there enough supplies for multiple attempts? What about clean up and storage. Let us know what are your favorites!

Here is one kit you can try.

This is a great post regarding the changing color of leaves in the fall. A wise man, whom I used to work with once said, and I stole this from another friends page, Thanks Curt. “The death of a leaf would probably go unnoticed if it did not die so beautifully.”
