I am not kidding when I say these are the softest cookies (at least that I have ever had)! and super fun and easy to make.

​I didn't use a spoon at all while prepping this batter- its much easier to just do it by hand and break up any lumps for optimal softness. Ask a parent for help with the oven, and share with the whole family!

On this very rainy Wednesday I got to thinking about the endless clouds in the sky and how they are formed. Clouds are formed when water vapor is warmed into liquid water droplets. These water droplets form on particles (think of something like dust) and they form the massive clouds that float above us every day!

Today we are going to repeat the cloud making process at home in a jar! To do this you will need the following materials…

- Warm (but not boiling) water
- A jar with a lid (a mason jar would be best)
- Ice cubes
- Aeresol Hairspray
STEP ONE:

1. Pour warm water into the jar and swirl it around. You want the jar to get very warm just not scalding hot
2. Turn the jars lid upside down and place a couple ice cubes on top and place the lid (still upside down) onto the jar.
3. Quickly remove the lid and spray just a 1-2 second spray of aersol hairspray into the jar and immediately place the lid back in the same position
4. Take the lid off and watch your cloud escape!

Now let's talk science! Read on to see how it works

Chromatography is defined as the separation of a mixture by passing it in solution or suspension or as a vapor. This week we are going to use...

• Paper Towels
• Washable Markers (washable is important)
  
• Two Cups
• Water​

Take the paper towel and fold it in half horizontally. Color only one end in small squares of each color to make a full rainbow (check the accompanying photo). You will do this on the opposite ends of the paper towel and place each of the colored ends into the glass of water and watch the magic happen!

Capillary action is what causes the color to move through the paper towel and moves the molecules of the markers through the paper towel. Because the markers are alcohol based and not water based the color will not travel through the water. 

Happy Coloring!

This week we will be learning about the power of hydraulics! Hydraulics have been used in the Western New York area since 1882. Check out the Youtube video below and see how engineers used the power of Niagara Falls to light up millions of homes.

You can even see hydraulics used in real time at our Kiddieland park! Our helicopter ride uses hydraulic lifts to get you off the ground and cruising the sky!
 ​

In the late 1700s hydraulic power was engineered by British engineer Joseph Brama. Hydraulic systems use pressurized fluid to create power. Hydraulics are based off of Pascals principle which in short is that pressure exerted on a fluid is distributed equally throughout the fluid. This creates a mechanical energy which can create enough power to be able to move massive pieces of equipment.

To recreate this project at home it is totally possible you just need some materials...
- Two syringes 
- Clear tubing/ piping
- Water
​
You can create your own hydraulic system by filling one syringe with water, connecting the piping to the tip of the syringe and then connecting a second syringe (not filled with water) to the other end. At home you can use this hydraulic system  to do  activities such as creating a hydraulic lift (kind of like a car jack) or you can even play with someone else and have a thumb war! Whose ever syringe is able to fully get rid of the water wins!

We will be practicing with hydraulics in the children's gallery of the museum on Saturday, September 19th from 10am-3pm! We hope to see you there!

This project is an eggcellent one.Do you miss going to ride the bumper cars at kiddielands? Us too! We decided to make our own sort of bumper cars out of...eggs! Eggs are eggxactly the right household item that we can make squishy and fun. We will be making a typical egg (uncooked) into a raw bouncing ball. For this experiment you will need the following...
- An egg
- A glass 
- Vinegar (white vinegar preferred)
- TIME
All you have to do to complete this experiment is place an egg in a glass and fill it with enough vinegar to cover the egg. The egg then needs to sit in the vinegar for upwards of two days. Check on it each night and see how different it looks! Take note of the differences the longer it sits. How does it feel? How does it look? After a while the shell of the egg will disintegrate leaving the egg completely raw. It may even be larger than when you started because some of the vinegar will absorb into the membrane and enlarge the egg. After the egg has sat in the vinegar for long enough you will be able to actually bounce it on the ground HOWEVER, do not drop it from too high up because the egg does have limits and it will eventually break!

Read on to learn more about the science behind this experiment! Also check out our photos to see how our experiment turned out. 

Week 8 is an electrifying one! We will be learning about the ins and outs of electric currents using  Squishy Circuits! Squishy circuits is a fun and hands on way to create various types of circuits. Using conductive dough we will demonstrate different ways to operate an actual circuit. This is a difficult project to recreate at home but if you would like to you can read below on how to make your very conductive dough!
Check out the squishy circuits website to see how these circuits operate

Happy STEMing!

Conductive Dough Recipe:
​
INGREDIENTS:
1 CUP WATER
1 1/2 CUPS FLOUR
1/4 CUP SALT
3 TBSP CREAM OF TARTAR
1 TBSP VEGETABLE OIL
FOOD COLORING (OPTIONAL)

INSTRUCTIONS

• Mix water, flour, salt, cream of tartar, and vegetable oil in a medium sized pot
• Cook together over medium heat and stir continuously
• The mixture will boil and eventually get lumpy
• Keep stirring until the mixture forms a ball in the pot
• Once the ball forms place the ball on a lightly floured surface, be careful it's very hot!
• Knead the ball with the remaining flour until you've reached the desired consistency, if the mixture seems too sticky add more flour. Add your food coloring to the dough and continue kneading until desired color has been reached.
• Ouila! Your dough is ready for use. Store it in an airtight container.

​This week’s STEM activity is a LONG one. In length I mean, not time! This week is a challenge to see how long of a paper chain you are able to make out of a single piece of paper. While this sounds simple it is actually can be a bit harder than you expect. Challenge a sibling, a friend, a parent (or all of the above). You don’t even have to be in the same room as the other person just make sure they are using the same size piece of paper. If you measure each of your paper trails you can compare numbers virtually! 
 
Here are the rules and regulations of this challenge:

1. Everyone must use the same size piece of paper (it doesn’t matter what kind of paper
2. Everyone must use the same type of adhesive (glue, tape, stapler, etc…)
3. You can cut and maneuver the paper in any way you want but make sure you think through your process before you start cutting. You only get ONE sheet of paper and once its cut there is no going back!
4. You may not use anything else besides the paper and your choice of adhesive when creating your paper chain.

This month we are reading Uni the Unicorn by Amy Krouse Rosenthal and illustrated by Brigette Barrager. Below is the information on how to tune in to our story time (available on the museum Facebook page) as well as a D.I.Y craft to make your own Unicorn horn at home! We hope to see you there!
