Learning Outcomes
Homework
Week 1 & 2 – I will be able to:
 Definition of mass, weight and gravity. Calculate the mass of
the dinosaur on different planets. Describe why two images of
the same animal would be shaped differently in different
gravitational fields. Devise questions to think about a
world without gravity and discuss how we would survive.
 Brief given on being selected to travel the solar system
and sent images back to Earth data given on planets and
instructions. Volunteers read out their space journal and
how they achieved their mission.
 What do forces do?
Find out what they know about Isaac Newton practical
measuring the mass and weigh of objects using a Newton
Meter. Second practical maltsters and straws how does
distance affect the force of gravity and normal force/
upward force.
 Label the layers of the Earth and describe physical state.
Students describe the process of continental formation
using convection currents. Make models of sedimentary
rocks. Use chemical and physical processes to observe
erosion.
 Make models of igneous rocks using salol and describe the
process for each size crystal, observe different types of
igneous rock and identify method of cooling. Describe the
