🖌️Painting with Salt! (Science🔬⚗️⚖️ 101 🎥Series 🎇)

Have you ever tried painting with salty water? This DIY activity is super easy and fun artistic activity to do with your child while exploring physical science on the topic of how the matter changes.

DSC_0026

You will need:

  • warm water,
  • salt,
  • dark construction paper (we are using brown paper, so that the white salt picture would stand out),
  • a paintbrush.

 Invite your child to paint a simple picture with the salty water on the construction paper. 

DSC_0026Set your painting aside and let the paper dry.  

DSC_0026Ask your child where did the water go?

Science mystery💡revealed: The warm water disappears because it changes into water vapor. The salt, on the other hand, a solid, remains on the paper and makes your picture stand-out. 

We read about this fun physical science activity in Change It! Solids, Liquids, Gases and You book (buy here), which offers many fun experiments to teach physical science to your child.


🎶Musical 💦Water 🌈Glasses (Science🔬⚗️⚖️ 101 🎥Series 🎇)

Have you tried making a water xylophone? This is a fun and scientific music activity you can do with your child at home. Just fill glasses with different amounts of water and invite your child to make music!

DSC_0014

 You will need:

  • identical glasses (we are using four tall crystal glasses) and these test tubes with this stand,
  • food coloring,
  • water,
  • we are using Xylophone sticks, but you can also use wooden sticks or a plastic spoon. 

Arrange glasses in a line and fill them up with water in equal decreasing increments (pouring less and less in the next subsequent glass). We added food coloring to give the water a color-pop. Invite your child to tap each glass and discover the sound each glass makes!

DSC_0014

Science mystery💡revealed: sound travels about four to five times faster in water than in air. So, water is affecting the speed at which the sound waves are traveling and vibrating.

This activity is a great way to stimulate senses, exercise your child's science skills, as well as musical abilities. You can even incorporate math by using measuring cups and fractions. Moreover, you can add a sensorial dimension to this activity by offering your child to create secondary colors by mixing primary colors together. Also, invite your child to "compose" a song or play a familiar tune. Finally, explain to your child the "magic" of sound waves. And, most importantly, have fun!

Magic🎈Balloon (Baking Soda and Vinegar Reaction) Science 🔬⚗️⚖️ 101 🎥Series 🎇

Today, we are continuing our Science🔬⚗️⚖️ 101 🎥Series 🎇 with this hands-on fun "let's see what happens to our balloon" science experiment when vinegar and baking soda chemically react.  DSC_0218-2

 What you will need:

  • baking soda,
  • vinegar,
  • balloon,
  • a bottle (we are using a sake pot - buy here),
  • funnel,
  • science glasses (buy pink here  and blue here),
  • a tray (buy here) and a mat (buy here) to contain everything. 

 Baking Soda/solid (NaHCO3) + Vinegar/liquid (HC2H3O2) → Carbon Dioxide/gas (CO2) + Water/liquid (H2O) + → NaC2H3O2 
DSC_0218-2Science mystery💡 revealed: Baking soda and vinegar create an acid-base reaction of atom exchange, producing, as a result, the carbonic acid which is very unstable. Carbonic acid instantly breaks apart into water and carbon dioxide, the latter of which is gas. Gass needs a lot of room to spread out and the carbon dioxide starts to fill the bottle and then moves into the balloon inflating it. 

DSC_0015During this chemical reaction between the base (baking soda) and the acid (vinegar), the resulting gas attempts to escape the bottle, moving up into the balloon because of the tight seal around the bottle. Because the gas has nowhere to go, it pushes against the balloon, inflating it!

p.s. It is very similar to when we exhale carbon dioxide to blow up balloons. (Adrian insists us do it at least once a day :)

🌌COSMOS Unit Study

There is something fascinating, captivating and intriguing about the Universe! Although Cosmos appears empty and dark, it sparkles with thousands of mysterious glittering lights. Also, while purportedly having an infinite nature, the universe keeps expanding! It holds billions of galaxies, each containing millions of stars, and although the space between stars and galaxies is largely empty, it contains particles of dust, radiation (e.g. light and heat), as well as magnetic fields and high energy particles (e.g. cosmic rays).

Children also love reading National Geographic Kids First Big Book of Space (buy here). This book, with its colorful illustrations and simple text, introduces young children to the wonders of Space, explaining basic concepts of the universe, beginning with what is most familiar and expanding out into the cosmos.

DSC_0024These flash cards about Outer Space (buy here) are amazing! They feature full-color photographs, many taken from NASA's own spacecraft. The back of each card offers young space explorers easy-to-understand facts about planets, stars and spaceships in our Solar System.

DSC_0029Our "Solar system"  - what does it mean? "Solar" means "of the Sun," and a "system" is a collection of objects that interact with one another to form a whole - that is the fundamental interaction for each object being the one it has with the Sun. There are many different types of objects found in the solar system: a star (our Sun), planets, moons, dwarf planets, asteroids,comets, dust and gas. The Sun comprises over 99.8% of the Solar System mass (being the biggest object in our system), with Jupiter (The Gas Giant) accounting for most of the remaining mass. All objects in our Solar System orbit the Sun - that is move around in elliptical paths. The Sun exerts enormous gravitation pull, keeping orbits of these objects, called the ecliptic planes, roughly the same, thus preventing collision or any object going astray.

DSC_0013The Universe is incomprehensibly huge: it would take a modern jet fighter more than a million years to reach the star nearest to the Sun. And, traveling at the speed of light (300,000 km per second), it would take 100,000 years to cross our Milky Way galaxy alone. Adrian used Imagination Magnets (buy here) to assemble a rocket ship. The set contains colorful pattern cards which are numbered in progressive order of difficulty, ranging from beginner to expert. As each pattern becomes more challenging, patience and confidence is gained through trial and error. (See here a post "Imaginets, Magnetic Pattern Geometric Shape Blocks & HAPE Wooden Mosaic Puzzle.")

This hand-crafted ✨Solar System set (buy here) has been children's favorite hands-on material to go along any solar system discussion! These needle felted planets, made from wool and organic cotton, are proportionally sized to each other with names embroidered on the back. Adrian loves how 🙌🏻hands-on COSMOS study can be! He can basically hold the Solar System in his hands.

 
DSC_0024We also talked about terrestrial (rocky) planets (1-4) and gas giants (5-8), and the asteroid belt that separates the two.

SENSORIAL ACTIVITY
IMG_6640See here the post  ✨The Universe 👋🏻Sensory Bin (🌌COSMOS Unit Study).

No one knows the exact size of the Universe since we simply cannot see the edge (if indeed there is one). All we know is that the visible Universe is at least 93 billion light-years across. (A light year is the distance light travels in one year – about 9 trillion km.) However, scientists believe that the Universe was not always the same size. They propose that before the birth of the Universe (the Big Bang which took place nearly 14 billion years ago) time, space and matter did not exist. However, one of the theories is that since the Big Bang, the Universe has been expanding outward at a very high speed, meaning that the area of space we now see is billions of times bigger than it was when the Universe was very young. Such would also imply that the galaxies are also moving further apart as the space between them expands.

🎨Painting with 🌈Colored Vinegar on Baking Soda Science Experiment 🔬 💡⚖️ 101 🎥 Series 🎇

Today, we are continuing our Science 🔬 💡⚖️ 101 🎥 Series 🎇 with this super fun painting with colored vinegar on baking soda experiment.  

DSC_0041

What you will need:

  • a tray with baking soda,
  • colored vinegar (we are using this mini measuring beaker set),
  • different droppers, 
  • science glasses (buy pink here  and blue here).

Baking Soda/solid (NaHCO3) + Vinegar/liquid (HC2H3O2) → Carbon Dioxide/gas (CO2) + Water/liquid (H2O) + → NaC2H3O2 

DSC_0041
Science mystery💡 revealed: Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a base while vinegar is an acid. When they react with each other because of atom exchange, they form carbonic acid which is very unstable. Carbonic acid instantly breaks apart into water and carbon dioxide, the latter of which is a gas responsible for all the fizzing as gas escapes the solution. This ⚗️chemical reaction releases gas because when baking soda receives proton from vinegar, it transforms into water and carbon dioxide molecule which since now is free of its other chemical bonds, can escape, bubbling forth as a gas.
