Week 4  SiIly Science

Chemical reactions.

A chemical reaction is the combination of two reactants to form an entirely new product. Bonds are broken and new bonds are created. A chemical reaction is not always caused by mixing two substances together.

 

Erupting volcanoes.

You will need;

  • ¼ cup of vinegar
  • Red food colouring
  • Washing up liquid
  • 1 tablespoon of baking soda
  • Play dough

What to do;

 

Clear a work surface and cover it with newspaper or a vinyl table cover.
Model a volcano out of play dough.
Make a hole at the top of the volcano.
Stir in 1 tablespoon of baking soda
 Add a few drops of red food colouring
Add a few drops of liquid dishwashing detergent.
Get ready!  Pour in ¼ cup of vinegar and watch!

What is happening?

Wait and watch, as the volcano will erupt in a few minutes with bright red frothy lava. The eruption is acid meeting another substance called an alkali.

Non cook Play Dough

 

2 cups of plain flour

1 cup salt

1 tbsp oil

1 cup cold water

2 drops of food colouring

 

  • First mix plain flour and salt.
  • Next add water, food colouring and oil until all combined.
  • Knead well.
  • If consistency is too wet, add a little more flour.

 

 

Week 3 Silly Science

Air Pressure.

Did you know that air pushed against you all the time? You cannot feel air pushing in on you because your body pushes outwards with the same force as the air.

Balloon hovercraft.

 

You will need;

  • Small plastic recycled drink bottle stopper screw top lid.
  • Balloon.
  • Old cd.
  • Scissors, glue, cellotape.

 

What to do;

Take the lid and glue or tape the top of the cap to the centre of the cd.

Place the inflated balloon onto the lid.

Release the stopper.


High-pressure air from the balloon flows under the even flat surface of the cd making an air cushion – also known as air bearing – for the hovercraft to float on with little friction.What is happening?

 

Use your hovercraft on a number of different surfaces to investigate where it works best.

 

Week 2 - Gravity.  

The Earth tries to pull everything down towards its centre. This pull is called the force of gravity (the invisible force). When you lift things up you have to pull against gravity. If you drop a pencil, gravity pulls it to Earth. If you rest its mid-point on your finger, gravity will pull down equally on both sides of the pencil and it will balance in the air.

The clown that won’t lie down.

You will need;

  • Pens
  • Scissors
  • Sticky tape
  • Ping pong ball
  • Play dough
  • Thick Paper (10cm x 5cm) or (4” x 2”)

 

What to do;

Cut the ping-pong ball along the join line of the ball all the way around.
Place the paper snugly inside one half of the ball and tape the outside to form a tube, by placing tape around the bottom of the tube and onto the ball.
Draw a clown’s face on the paper tube (the half ping-pong will be the clowns’ feet).
Try standing your clown up (on the half ping-pong). Will it stand up?
Put some play dough into the base of the clown and press it to get the clown to stand.  Now try to push the clown over.

What is happening?

The clown will not lie down when you push the play dough in the base of the clown.  Gravity pulls on the clown’s base so that it stands up.  If you try to push over the weighted clown, gravity still pulls on its base and the base will stay down and the head will flip up.

Flipping clown.

 (A continuation from the experiment - Clown won’t lie down.)

 

You will need;

• Tape
• A Marble
• The other Half of the Ping-Pong Ball

 

What to do;

 

Take the play dough out of the ping-pong base.
Put the marble in the base.
Tape the other half of the ping-pong ball to the top of the paper tube.
Stand the clown on a slight slope.

 

What is happening?

The clown will flip from head to toe and over again as the rolling marble makes the centre of gravity move from one end of the clown to the other end.

Gravity - The clown that won’t lie down.

Silly Science - Year 2 and Year 6smiley

The first week of silly Science club we made Slime!!!!  It was AMAZING! (and slimy) We all had sooo much fun.  If you'd like to make it at home here's what you need....

 

What to do;

Pour some corn flour in the bowl.
Add a little of the food colouring to the water. (Food colouring can stain so be very careful).
Slowly stir in some of the coloured water in with the corn flour (adding a few drops at a time).
Continue to stir with the wooden spoon until it starts to thicken to a paste. You may find that you need to add more water or corn flour to get the right mix.
Take a handful and watch it ooze out of your hand. It flows like a slippery liquid.
Squeeze the slime and it becomes a solid.

THIS EXPERIMENT CAN BE VERY MESSY, SO PLEASE TAKE CARE AND BE PREPARED!!!
