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!
Kids’ Science – Gravity For Beginners
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!
Science, Religion and Philosophy
In our modern world it seems as if natural science is completely incompatible with religion and (to a large extend) philosophy. In spite of some imaginative scientists trying to soften and modify the scientific community’s view of the world as a huge machine, the general impression is that a war between two different world views is taking place. On one hand the scientific view of the world as pure matter without any kind of spirit (and certainly not any kind of divine purpose or interference) and on the other hand the religious or philosophic views where spirit (and in many cases also some kind of divine power) plays an important role in our whole existence.
Why does it have to be like that? Albert Einstein, who is regarded as one of the greatest scientists of all times, said: “Science without religion is lame. Religion without science is blind.” If one of the most esteemed scientists in modern times found it necessary to combine the two subjects then, why does the vast majority of scientists and religious representatives continue their seemingly endless fights?
It is evident that natural science explains a lot about nature and our universe. It is a fact that without science we would not have been able to create our modern civilizations with complex infrastructures enabling us to travel by land, air and sea. We wouldn’t have computers, cell phones and internet. Modern hospitals, institutions and organizations would not exist…
But the fact that natural science has helped us immensely in understanding the nature surrounding us doesn’t necessarily mean that we can find all answers that way. Our consciousness is still a mystery to natural science because it can only be experienced as a first-hand, subjective experience!
On the other hand, most religions are based on very old information that was originally given to people much less educated than the majority of people today. Also, it might very well be distorted by misinterpretations and misunderstandings during centuries. Nevertheless, in spite of all the wisdom contained in these religions it would have been impossible for anybody to explain scientific laws to people at that time. Remember that until a few centuries ago everybody was convinced that the earth was flat and also the center of the universe!
To me, modern philosophy should include knowledge from both natural science and religion. If scientists on one hand and religious people on the other hand are reluctant to change their views (maybe partly because it would force them to change their whole personal identity), philosophers ought to be seeking the truth without prejudice.
I also think that philosophy should include a total world view. In spite of the standpoint of existentialism that the individual has total freedom and responsibility to create his values alone, I find it very important to have a total personal world view.
Without a fundamental and comprehensive world view we are (in spite of the evolutionary principles) lonely beings in a world of chaos, coincidence and injustice.
