121 Plus 9 Chemistry Experiments for kids is an excellent book to teach the subject with cool experiments. Read with your kids and help them understand the chemistry behind various things.
Do water molecules really move? If so, how fast and how slowly? Things Required:2 clear glassesFood colouringCool and hot tap waterMedicine dropper Directions:Fill one glass with cool tap water. Fill the other glass with hot tap water. Now, quickly place one drop of food colouring in each glass. (Make certain that all the variables are […]
See the effect of molecular motion. Things Required:Dark food colouringTall, one-half pint jar of water Directions:Place the jar of water where it will not be moved or touched for 24 hours. Hold the food colouring container above the water and allow two drops of colouring to fall into the water. Observe immediately and then again
The purpose of this experiment is to move a balanced toothpick without touching it or any object connected to it. Things Required:Clear plastic drinking cupflatToothpick coin (small)Balloon Directions:Stand the coin up on its edge. Balance the flat toothpick across the top of the coin. Carefully cover this balanced combination with a clear plastic cup.“Charge” an
You can demonstrate the movement of molecules in solids, liquids and gases in a simple way. Things Required:A small box lid (or flat box with short sides)Marbles (or any other small spheres or balls)Scissors Directions:Place a layer of marbles or balls in the lid so that they may be jammed close together. Move the lid
This experiment illustrates that atoms have positive and negative parts. Things Required:Piece of notebook paperPaper hole punchBalloon (use a size easily held in your hand) Directions:Use the hole punch to cut 75 to 20 small circles from the piece of paper. Separate the circles and spread them on a table. Inflate the balloon and tie
Here, you will observe physical properties and their changes. Things Required:3-x-5-inch index cardScissors Directions:Observe the following physical properties of the index card. Colour, shape, size and texture (how it feels). Fold the index card in half along the long side. Before starting the cuts, study the diagram for the following things:Notice that all of the
Now, challenge your brain power. See how many isomer models you can make. Try this with friends. It makes a great brainteaser! Things Required:6 paper clipsPaper and pencil Directions:Take one paper clip. Place it in front of you. You have made your first pattern. Can you make any more with just the one clip? Select
Can you identify an unseen object? After this experiment you can. Things Required:Ball of clay with a small object insideToothpick Directions:Have someone secretly wrap the clay around a small object and mould the clay into a ball. The object must be firm enough so that the pick may not break it. Poke the toothpick into
This experiment demonstrates inertia, a property of matter. Things Required:Index cardA coin of any sizeDrinking glass Directions:Lie the index card over the mouth of the glass. Place the coin on top of the card. Its position is to be centred over the mouth of the glass.Snap the card with your finger.This Is What Happens:The card
An easy way to start learning about atoms is to make a model of an atomic orbit. Although electrons and protons are not clay balls (in fact, electrons are fast-moving; electrically charged particles that move faster than you can say “atom”). Making a clay model will help you understand that it can be a very
