Summer 1 - Science Evolution

We completed a carousel of Science Activities, finding out about Natural Selection and we even completed further research about fossils.  

LO. Define evolution as the gradual changing of the features of species over time.
LO. Explain in simple terms how natural selection works.

Y5/6 I can read, spell and pronounce scientific vocabulary accurately.
Y5/6 I can relate the outcome from an enquiry to scientific knowledge in order to state whether
evidence supports or refutes an argument or theory.
Identifying scientific evidence that has been used to support or refute ideas
Y6 I can link adaptation over time to evolution.
Y6 I can explain evolution.

Activity 1- Quick Natural Selection- Antibiotic Resistance
Development of antibiotic resistant bacteria, by natural selection, is relatively simple (few mutations required) and fast (occurs in days and takes just a few years to spread to many people) compared with the evolution of a new species of e.g. a mammal which takes millions of years. 

Activity 2- Natural Selection because of Camouflage
We looked at an example of natural selection, leading to altered populations within a species, which takes place over decades, in contrast to selection of antibiotic resistant bacteria which occurs much more quickly.  This famous example of evolution by natural selection started about 150 years ago. The insect involved, the peppered moth, spends the day resting on tree trunks, represented by the black and white boards

Activity 3- Drawing and researching a range of fossils

We know that:

-Many scientists have studied how living organisms change over time.
-We know that genes change or mutate to form mutant creatures or plants.
-When the environment changes some mutants survive better than others; they are naturally selected for.
-The creatures or plants that cannot grow well in the new environment may die out completely and become extinct.


How are cacti suited to survive in desert conditions?
How are plants adapted to live in very cold conditions?
How are plants in the rainforest adapted?

Plants produce large numbers of seeds, but only a few of them succeed in growing into mature plants (able to produce seeds themselves – have offspring).

What problems do seeds and young plants meet in the environment?

We conducted a mini investigation to reflect what happens in the wild. 
The wind increased in strength and changed direction numerous times during our investigation; we observed that this had a significant impact on the dispersal of our seeds.

Success Criteria

We can describe how plants are adapted for different environments.
We can explain why plants produce large numbers of seeds.
