Remember to always have fun with your children’s science experiments and don’t worry if their experiments don’t turn out as you would expect – some of the greatest scientific discoveries have been made by mistake (see sidebox).
With the aim of encouraging the budding scientist in your child, maybe you could suggest that your child keeps a notebook throughout his/her science experiments. This is so he/she can write down the experiments step-by-step and remember how the experiment was conducted, and the results achieved.
Here are some scientific ideas
Making a Volcano in a Bottle
Supplies:
Sand • Pouring Jug
1/2 Cup of Vinegar
Old Newspaper
Red Food Coloring
Bicarbonate of soda
A small plastic drinking bottle
Instructions:
1. Spread several sheets of newspaper down in an area that is safe to make a bit of a mess.
2. Put a tablespoon of the bicarbonate of soda in the opening of the plastic bottle.
3. Place the bottle in the middle of the newspaper area.
4. Position the sand at the base of the plastic bottle and shape the sand half way up the bottle to make it look like a mountain.
5. Put a few drops of the red food coloring and 1/2 a cup of vinegar in the pouring jug.
6. Pour the mixture into the bottle.
Wait and watch as the volcano will erupt in a few minutes with a bright red frothy lava.
Kid’s Solar Oven
Supplies:
Shoe box • Popsicle stick
Scissors • Aluminum foil
Edible snack to heat up
Instructions:
1. Line the inside of the box and the lid with aluminum foil. Tape the foil to the edges to keep it in place.
2. Cut a flap in the lid of the box. It should be one inch from the three sides of the lid. Fold the reflecting lid back so it sticks up. Put tape around the edges of the opening to keep the foil in place.
3. Place the lid back on the box and use the popsicle stick and tape to keep the reflective flap open.
4. Place the box in the sun with your favorite treat inside of the box. It could take a while, but depending upon the sun’s intensity, you can warm up a snack to enjoy. It may be very hot, so be careful.
