------------------------------------------------------
Heart biology
Hear your heart beating and see inside a real heart!
+ Make a working stethoscope and hear your heart beating
+ Watch a live heart dissection (lamb’s heart)
+ The older groups will also learn about the circulatory system and structure and function of the heart.
Please note that this session includes a live dissection of real organs
(lamb and possibly cow).
Equipment (To join an entirely optional practical)
It is a good idea to have a whiteboard or paper, pen, ruler and calculator to hand in each session.
- Blue tak or similar
- Plastic funnel (around 7cm diameter or similar)
- Balloon (rounded shape + spare)
- Scissors
- Cardboard tube, eg. kitchen roll inner (or silicone tubing / hose piping is better if you have it)
- Duct / gaffa / tough tape
What might younger students need help with?
Younger students may need support and preparation for the dissection of real organs.
They may need help using tape and scissors carefully and accurately.
------------------------------------------------------
Reflection
Discover how light is reflected and how we see!
+ Watch exciting demonstrations!
+ The older groups will also learn about the normal line, lines and angles or incidence and reflection and predict how different surfaces will reflect light.
Equipment (To join an entirely optional practical)
It is a good idea to have a whiteboard or paper, pen, ruler and calculator to hand in each session.
- A bright torch
- At least two small mirrors (the compact type that come with makeup are perfect, and the make up section can act as a built in stand)
- A4 white paper and pen (or whiteboard and pen)
- Ruler
- A piece of stiff card
- Scissors
- Silver foil
- A desert spoon (metal)
- Blue tak / similar
- Ability to darken the room will be helpful.
- Protractor (older groups)
What might younger students need help with?
Younger students might need help with careful cutting and use of scissors.
------------------------------------------------------
Osmosis
Extract water from cells and learn how it moves in living things!
+Make water move out of and into cells!
+Watch exciting demonstrations!
+ The older groups will also learn about concentration gradients and how osmosis is affected by solute concentrations in living things.
Equipment (To join an entirely optional practical)
It is a good idea to have a whiteboard or paper, pen, ruler and calculator to hand in each session.
- Potato, peeled and cut into at least 6 “chips”. Approx. 4cm x 1cm x 1cm (as equal as possible in size). Keep wrapped in moist paper before use so they don’t dry out (would also work with carrot)
- Cucumber slices (several), recently cut and covered so they don’t dry out
- Table salt (several teaspoons)
- Teaspoon
- Three jars / glasses / beakers
- Water
- Measuring jug / beaker
Links suggest sources of appropriate resources
What might younger students need help with?
Younger students might need help with careful handling of water. Cutting vegetables is best prepared beforehand.
------------------------------------------------------
Surface tension
Send boats shooting across water by breaking surface tension!
+ Watch exciting demonstrations!
+ The older groups will also learn about the intermolecular forces that cause surface charges and the polarity of water.
Equipment (To join an entirely optional practical)
It is a good idea to have a whiteboard or paper, pen, ruler and calculator to hand in each session.
- Paper
- Scissors
- Pen
- Large bowl or tray of water (take care near electronics)
- Washing up liquid / liquid soap (a few mL)
- Paper clip (regular size, not plastic coated)
- A 1p coin (other coins would also work)
- Pipette / dropper
- Small dish of milk (the higher the fat content the better!)
- food colouring (range of colours if possible)
- Cotton buds / “Q tips” (optional)
- Cloth in case of spills
What might younger students need help with?
Younger students might need help to keep liquids away from electronics and to avoid spills. They may need help using a pipette or dropper if they are not familiar with one. They may need help to change the water in the tray/ bowl.
