Spring Clubs 2019

Week 4

 

 

Today we entered the fascinating world of chromatography.  We watched how the molecules in inks behaved when they came into contact with water.

Did you know that red ink looks red because it reflects red light and absorbs all the other colours? When you mix green, red, blue, and yellow ink, each ink that you add, absorbs more light. This leaves less light to reflect to your eye. Since the mixture absorbs light of many colours and reflects very little, you end up with black. Try it!

Forensic Fun

Week 3

 

 

This week wasn’t for everyone… we looked at different ‘blood’ splatter patterns!  We used simple techniques to re create the common patterns that you can expect to see when a liquid is split.

You can try this at home with some water in the garden. See how many different patterns you can make by spilling the water in different ways.

 

Week 3.......Who done it???

Forensic Fun

Week 2

 

 

This week we looked at our own fingerprints and had fun finding others on different objects.

Did you know that everyone has unique fingerprints?  Even identical twins!

Why not look at the fingerprints of people in your family and see how different they all are?

Forensic Fun

Week 1

 

 

Our club started with us examining footprints - our own as well as those left at our ‘crime scene’.

Next time you are out walking, see if you can find any footprints and try and work out who or what may have left them!

Forensic Fun.......

Over the next five weeks we are going to solve a murder!
We will examine; footprints, fingerprints and blood patterns, amongst other clues that we are given.
This murder is NOT a real case, but it does simulate the processes that real Crime Scene Investigators and Forensic Scientists have to go through to present evidence for court.
We will treat this as a real case, and you as real investigators.
You will work in teams and have a form to collect your ideas on weekly, which will be kept here.

Examining the evidence..........Footprints

Fl

Floating & Sinking.

Diver in a bottle.

You will need;

• Paper Clip
• Plastic Pen Top with Clip
• Plasticine
• Empty Plastic Water Bottle with Lid (2L)

What to do;

Make a plasticine (modelling clay) figure 3.5cm (1.25in) long.  Fix the paper clip to its head and hang it from the pen top.  Fill the bottle with water and drop in the scuba diver.
The pen top should float with its top just above the water level.  Make the figure bigger or smaller if needed.  Then pour in more water and screw the top on tightly.  Now gently squeeze and release the bottle to see what happens.

 

What is happening?

When you put the pen top in the water, a bubble of air is trapped inside it.  This trapped air bubble makes the diver less dense than water, so it floats.  When you squeeze the bottle, water squashes the air and takes up more space in the pen top.  Now the diver is denser than water, so it sinks.  When you relax your grip on the bottle, the air in the pen top expands again.  Now the diver is less dense than water, so it comes back up to the surface.

 

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!!!
