Evidence for Evolution

How do paleontologists learn about evolution?
Through the understanding of the geology of earth layers. This leads to the adaption of features grown to adapt into the environment which they have to apply to. We can understand this through the fossil. These horses have adapted to environment
Describe what fossils reveal about the evolution of the horse

What are vestigial structures? Give an example.

Define Bio-geography
The study of biological creatures in the form of their geography and how they lived in their habitat and how they arrived. Information provided by Anaru Jackson.
Describe an  example of island bio-geography that provides evidence of evolution

Science | Boiling Water Experiment Report.




Aim

[Copy] Measure the temperature of 50 ml of water as it boils and find how long it takes to boil.


Equipment

Bunsen Burner, Gauze Mat, Water (50ml), Safety glasses, Tripod, Beaker, Measuring Cylinder, Gas

Method

[Copy]

  1. Measure exactly 50 ml of water in the 100 ml measuring cylinder.
  2. Put this water in the 250 ml beaker, and set that up on top of the tri-pod and gauze mat.
  3. Prepare the bunsen burner to be lit, and have someone ready to measure the temperature and someone keeping a track of time.
  4. Have a table prepared for results.
  5. Light the bunsen burner (I will supply a lighter), and change to the blue flame then put the bunsen under your beaker.
  6. Measure the water temperature every 30 seconds from 0 to 5 minutes.
  7. Turn off the Bunsen burner and leave everything to cool off for a few mins.
  8. Pack up your equipment.

Results

Conclusion

The experiment was a success as we boiled the water as hot as we could in 5 minutes. We knew this because the temperature exceeded 100 degrees. Our graph has shown the results in temperature and time.
