Here’s a science activity for kids that offers basic exposure to density and the law of gravity. It also gives your child an opportunity to engage in the trial and error method of problem solving. It’s very simple and lots of fun.
You’ll be making a miniature version of hot air balloons. Each balloon should take about one minute to make. Your child will love helping to put the hot air balloons together.
Here’s what to do:
Pick up helium balloons from your community party supply store. You’ll need one balloon for each participant.
For the basket part of the hot air balloon, use a paper cup or 12″ x 12″ felt square. If you use a paper cup, tape three pieces of string to the top of the cup, and then tie the string to the base of the balloon. If you use a felt square, tie each of the four corners and attach those to the base of the balloon. (If you want to go a step further, for a more realistic looking basket cut off the bottom four inches of an empty bag of specialty coffee and rinse it out-the material is perfectly suited for this activity.)
Your living room is the perfect location to get started.
The objective: fill the basket with just enough household items to cause the balloon to hover for ten seconds without touching the ceiling. The items might include marbles, buttons, bottle caps and Q-Tips. Put these items in a bowl for selection. Keep a pair of scissors handy–as your child fine tunes the density it may become necessary to cut a Q-Tip in half.
Consider the following variation: put all the items in a line for selection. Take turns selecting one item until each person has ten. Place items into balloon baskets and launch the balloons. The objective is to have your balloon float slowest to the ceiling. In order to improve results, each person may exchange one of their items for a new item. Re-launch the balloons. Continue the process of exchanging one item after each launch. Keep experimenting until one player causes a balloon to hover for ten seconds.
There are many other variations to this science activity that you can pursue on your own (–for example, log the difference in items used from one day to the next as the balloons lose helium). Regardless of how you go about it, this activity will give your child an opportunity to engage in trial and error problem solving while gaining basic exposure to density and the law of gravity. You may also find it surprisingly adept at bringing out the fidget and tinker nature of parents. Have fun!

Kids’ Science – Measure Stuff
Measuring stuff around the house is a fun and easy science activity for kids. It’s perfect for Saturday afternoons or whenever you want to spend some quality, stress free time with your child. These simple measurement games are flexible enough to grow with your child’s developing skills.
Here’s All You’ll Need to Get Started:
-Tape measure
-Ruler
-Paper and pencil
Activity 1
The Alphabet Game
Here’s how to play this measuring game…
Hunt for three things around the house that start with the letter A. Measure each item and log the measurement on a piece of paper. (Hint:round to the nearest inch.)
Now hunt for three things around the house that start with the letter B. Measure each item and log the measurement on a piece of paper.
Next hunt for three things around the house that start with the letter C. Measure each item and log the measurement on a piece of paper.
Now put a check mark next to the biggest item. Put a circle next to the smallest item.
(Advanced: how many of the smallest items would it take to equal the length of the longest item?)
Activity 2
1/2 a Sandwich and a Cup of Soup Please
Here’s how to play this measurement game…
Measure the length of your couch. Log the result on a piece of paper. Now find something around the house that is approximately 1/2 the length of the couch–for example: the width of your dining table. Measure it, then log the result on a piece of paper. Now find something that is approximately 1/2 the width of your dining table–for example: a picture on the wall. Measure it, then log the result on a piece of paper. Now find something 1/2 the width of the picture on the wall–for example: your toaster. Measure it, then log the result. Now find something 1/2 the width of your toaster–for example: 1/2 a sandwich. Measure it, then log the result. Keep playing until you find something that is approximately one inch long–a peanut for example. Log the result on a piece of paper.
(Advanced: keep track of how long it took to complete the activity. Compare the result each new time you complete this activity. What’s the trend?)
Activity 3
Double Double!
Here’s how to play this game…
In this game, start by measuring your child’s nose. If you measure the width, it should come out to approximately one inch. Log the results. (Your child will love seeing something like ‘Claire’s nose: 1 inch’ on your chart). Now find something approximately double the length–for example: a strawberry. Measure it and log the results. Now find something approximately double the length of the strawberry. Measure it and log the results. Keep going until you run out of things to measure.
(Advanced: measure the entire length of your house. Using that figure as a guide, estimate the distance to your mailbox, nearest park or grocery store).
Measuring things goes hand in hand with the fundamentals of science. These activities offer basic exposure to measuring procedures, and can be played again and again. As your child becomes more skillful at measuring stuff, work toward more precise measurements by rounding to the nearest 1/2 inch, and eventually to the nearest 1/4 or 1/8 inch. A good way to engage in even more precise measurements is to measure coins or book ends to the nearest 1/16 of an inch! Be sure to record the results. Have fun!
Astrology – A Science?
Astrology is thriving from times immemorial, playing on the hopes and anxiety of mankind to know about tomorrow. Based on the planetory positions and their reported influences of the human beings, this pseudo-science has been taking the mankind for a ride all these years. People practising this weird art, have been claiming that this is a science. The astrologists predict our future and tell us about our past. They practise the art of reading a man’s mind in distress and make predictions that would definitely soothe his anxious feelings. It is a moot point whether their predictions come true. But for the mind that is seeking refuge in small things of comfort, these forecasts and prophecies come as a drink of cold water in a desert.
Astrolgers and astrology have been part and parcel of the ancient kingdoms. Touted as a science , people flocked in large numbers to listen to oracles and soothsayers. The fear of the unknown pushed many people to spend money on consulting these self-styled pundits. In reality , this occult science has no real scientific basis. They do calculate the ephemeral and other astronomic numbers but any resemblance to science stops there. The zodiac is divided into twelve signs, known as Sun Signs. There are specific personal characteristics and traits for persons born under each Zodiac Sign. In India, they have what is known as Moon Signs. These are based on a group of two and a half stars in 12 signs. (There are 27 birth stars). Each star , like the zodiacal sign, attributes special characteristics and traits for persons born under it. Based on the planetory position at birth and the planetory periods of the particular person at present, predictions are made. The predicitons are mostly highly generalised and broad. Seldom specific forecasts are made.
Astronomical science has progressed far from the days of the ancient kingdom. Man has landed on the Moon and has already successfully landed unmanned probes in other planets. Extreme temperature conditions and lack of oxygen make these planets devoid of any signs of life. How these planets can be said to be influencing the day to day lives of the people on earth? Destiny, Astrology all these things belittle the human endeavour and his spirit for adventure. If everything has been decided in advance and if everything could be foretold, then why do mankind still engage in a mad race for material wealth?
