What you need

  • Baking soda
  • Vinegar
  • Food color
  • Medicine Dropper
  • Muffin pan or small cups
  • Baking sheet or tray

How to

  • Fill 1/3rd of the tray with baking soda.
  • Pour vinegar into the muffin pan.
  • Add drops of food color to it and mix.
  • Use dropper to press and drop the vinegar in the tray to watch it fizz.

A(3.5) & D(2.5) thoroughly enjoyed this activity. Using a dropper is great for developing fine-motor skills, pencil grasp, hand eye coordination and concentration.

They didn’t get a good hold of the dropper and felt it was too slow. A touched the dropper in the baking soda and dipped it in the muffin pan to see the vinegar bubbling. Later D joined her.

It was mesmerizing to watch. They kept doing it until the vinegar no longer reacted to the baking soda. 

This was so much fun on a rainy summer afternoon. I loved to watch their face gleam every time they heard the fizz and saw the bubbling reaction.

Magic Milk – Science Experiment

Magic Milk experiment is very popular on Pinterest. I came across this a few months back, but didn’t want to waste milk at home. A couple of weeks back we had some milk past best before date, hence tried this. This is a simple activity to discuss about chemical reactions.

Follow us on Facebook

What you need

  • 2% or whole milk (i used whole milk)
  • food coloring
  • dishwashing liquid
  • cotton swab (Q-tips)
  • Bowl or plate

How to

  • Pour enough milk onto a bowl or plate to cover the bottom.
  • Add few drops of food color to it. We used red and yellow.
  • Dip a cotton swab in dishwashing liquid.
  • Dip the coated swab in the milk.
  • The colors will swirl as soon as the dishwahing liquid contacts the milk. 

This was very interesting to observe. Miss A(3.5) & Miss D(2.5) thoroughly enjoyed watching the colors swirl. They kept doing it until the milk no longer reacted with the dishwashing liquid. At one point A poured in all the dishwashing liquid into the milk to see what happened. They wanted to do this again and again, so we repeated it once more. 😀  I explained to them, that the swirls created is actually a chemical rection between the dishwashing liquid and the fat in milk, but they didn’t really seem to care. The swirls were too mesmerizing. This experiment is something you have to do to see and enjoy the results.

The science behind it

Milk consists of a lot of different types of molecules, including fat, protein, sugars, vitamins, and minerals. If you had just touched a clean cotton swab to the milk (try it!), not much would have happened. The cotton is absorbent, so you would have created a current in the milk, but you wouldn’t have seen anything especially dramatic happen.

When you introduce detergent to the milk, several things happen at once. The detergent lowers the surface tension of the liquid so that the food coloring is free to flow throughout the milk. The detergent reacts with the protein in the milk, altering the shape of those molecules and setting them in motion.

The reaction between the detergent and the fat forms micelles, which is how detergent helps to lift grease off of dirty dishes. As the micelles form, the pigments in the food coloring get pushed around. Eventually.​ equilibrium is reached, but the swirling of the colors continues for quite a while before stopping.

Pond Sensory Bin – Preschool Science

Spring is the perfect time to explore pond life. This pond sensory bin is a hands-on sensory science activity for preschoolers to learn about pond and the animals that live in it. This was simple to create and worked well for our pond life unit. Learning while playing is always fun and kids remember it more easily.

Follow us on Facebook

What we used

  • Water beads – (we used aqua color, looked much like green)
  • Storage bin
  • Pond Animals – swan, duck, goose, frog, snake, fish erasers ( add turtles)
  • Acrylic leaves ( you could add lily pad made with green foam sheet)
  • Plastic plants
  • Plastic flowers
  • Green wooden blocks
  • Green plastic Easter eggs – for moss
  • Cinnamon sticks – for logs

For Miss A(3.5) this was a learning activity- introduction to what is a pond and pond life. For Miss D(2) this was more of an sensory, imaginary play and learning about different animals.

I told them the waterbeads represent the water in the pond and we can find different animals and plants in the pond – animals, leaves, flowers, small plants, moss, rocks, log, etc. Kids named the animals and other items in the bin.

We also spoke about what the animals in the pond eat. A didn’t like the idea of one animal eating the other. When i told her the snakes eat the fish in the pond, she was very upset. She told me, mummy the fish will be very sad now.. ☺️(aww the innocence and sweetness).

Because we are learning about five senses, I let them smell the cinnamon stick and spoke about how we use our nose to smell – D loved the smell, A didn’t like it much.

Once done with the learning and watching a short video about pond life in YouTube they took to playing with the bin.

They sang some songs playing with the pond animals in the bin – five little speckled frogs, five little ducks went swimming one day, 12345 once i caught a fish alive. Then they filled the easter eggs with waterbeads – scoop and pour, fill and shake to hear what sound it made.

In the evening we drove to the nearby pond – although A was a little upset because there were no waterbeads in the pond 😂

The kids enjoyed learning about pond life with this sensory bin and i was really proud when A told her dad, once he was back from work about the type of life we can find in the pond. 😀

      Sink or Float – Preschool Science

      Last weekend we did a fun experiment! We put a bunch of items in a bin filled with water to see if they would sink or float. It’s a great hands-on science activity for preschoolers and really gets them thinking. Ever since we did this activity my LOs keeps asking me to do it again.

      Follow us on Facebook

      Whether an object sinks or floats in a liquid depends mainly on two factors: density and buoyancy. Preschoolers should be encouraged to observe whether the same objects will sink or float every time – that there is consistency in the way the objects behave. This activity helps kids categorize a variety of objects according to observable characteristics.

      Here’s how we set up our sink or float science experiment.

      What you need 

      • Container or storage bin
      • Water
      • Objects collected from around the house

      How to

      • Fill a large container with water. We used a toy storage bin.
      • Collect items to test out. 
      • We used stainless spoon, eraser, toy car, acrylic leaf, plastic scissors, plastic easter egg, plastic fruit, small bouncy ball, wooden block, lego, puzzle piece, toy happy man. I made sure to collect two of each, so both kids get to see what it does – float or sink.
      • Suggested materials for this activity – wood, metal, plastic, aluminum foil, apples, oranges, plastic bottles, toy blocks, paper, bathtub toys, plastic forks, rubber balls, soda-bottle caps, pencils, erasers, and sponges.

      Everytime Miss A(3.5yrs) dropped an item inside we tried to take a guess and observe what it did. We thought lego will sink, but it floats! This was really interesting for her. She learnt new words float and sink and knows what it means. 

        For Miss D(2yrs) its was fun dropping items in water. She did observe each item to see if which item went down(sinks) or which item stayed up(floats) But was more interested in dropping them in and picking it up back from water.

        We had a sheet with words sinks & floats written on it. A did this experiment all by herself and sorted the items in the respective columns. D & me sorted items by looking at which goes down & which stays up. Later the paper got wet, so we had to use a large bin. We kept repeating it for a while – rechecking by putting just the items that float and just the items that sink. This little science activity was a big hit with my kids.

        Note: Do this in a place where you don’t mind getting wet and easy to clean up. I used a tray below the water bin to hold spills, but we still got the floor a little wet. If the weather is good you might consider taking it out. We will definitely be doing this again on a warm day outside in our water table.

        Oobleck – Sensory Science Play

        What is Oobleck?

        Oobleck is a non-Newtonian fluid; it has properties of both liquids and solids. Its pressure dependent – You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid. 

        The name oobleck comes from the Dr. Seuss book, “Bartholomew and the Oobleck.” In the story, oobleck, a gooey green substance, fell from the sky and wreaked havoc in the kingdom.

        Oobleck makes a great science project or simply have fun playing with it, like us. 😀

        What you need

        • 1 cup water
        • 2 cups cornstarch
        • Green food coloring (optional)

        How to

        • Add few drops of food coloring to water. Mix well.
        • Add cornstarch in to a storage bin or bowl and add colored water a bit at a time.
        • Keep stirring until it has a gooey consistency. You may want to use your hands.
        • Oobleck is now ready to play with.

        Follow us on Facebook 

          Miss A(3yrs) & Miss D(2yrs) had so much fun playing with it. I underestimated this activity – didn’t expect it to be this awesome. We all enjoyed it! (Even hubby!!). It was an amazing experience. My kids were playing with it for more than an hour. They did get themselves and the place messy but cleaning was easy – just clean using water 😀 Plus all those laughing is so much worth the mess. 

          You could also make huge quantities of oobleck – in kids water pool and enjoy it outdoors. If you make enough, you can even walk on it. Something i want to try in summer.

          Here’s what we did with the Oobleck

          • Grab a handful and squeeze it – it oozes through your fingers.
          • Make a puddle and quickly drag your fingers through it. My LOs tried to cut it using playdough knife.
          • Roll some oobleck into a ball. It becomes solid, but when you stop moving it, it will melt back into your hand.

          Magnifying Glass Match Up – Free Printable

          I got a magnifying glass last year but my kids were not ready for it then. We used it once during Fall to view the details on the fall leaves and then totally forgot about it.  This year we plan to use it more. 

          I set up this Match Up activity for my LOs to understand the use of a magnifying glass. It also helps learn basic math concepts like comparison of size and matching, strengthen their vocabulary by naming the objects on the game board. 👍

          What you need

          • These printouts – 1 & 2 – free download
          • Magnifying glass – ours was from dollar store

          How to

          • Print out the cards and laminate.
          • Cut out the miniature pictures.
          • Use the large pictures as game board – do not cut them.
          • Let your LOs use the magnifying glass to view the miniature pictures and match them up to the large pictures on the game board.

          Miss A (3 yrs) liked this activity a lot. She kept doing it over and over again. The construction vehicles was a new lesson for her. She learnt the names of construction vehicles and tried to match the ones we have at home to the pictures. We will be doing a unit on construction vehicles soon. 😀

          Fizzing Hearts – Science Activity

          Fizzing Hearts is a classic science activity – a great way to introduce the concept of chemical reaction for preschoolers. Baking Soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide and water. The fizz produced is fun for kids to watch. This activity is perfect for Valentines day theme or just anyday 😀

          What you need

          • Baking Soda
          • Food color
          • Vinegar
          • Heart shape silicone mold
          • Squeeze bottle

          How to

          • Mix few drops of food color to baking soda.
          • Add few drops of water if needed. The mixture should be slightly wet yet crumbly.
          • Press them into the molds and Freeze for about 30 mins.
          • Take the hearts out of the molds, place them in bins or muffin pans. We used toy storage bin.
          • Fill the squeee bottle with vinegar and give them to your kids. Let them see, hear & enjoy the fizzing, squirting vinegar over the hearts.

          Miss A(3yrs) & Miss D(2yrs) enjoyed this activity alot. We spoke about different colors, explained why the fizz was created and also noticed how the colors blended to form a green color solution(given the colors of hearts). Each time the heart fizzes my LOs would scream of joy, “look mummy bubbles”😀 We had so much fun, lots of laughs, squirting, hissing noises.. That was one fun evening!
