If you are looking for a tutor to help your children to understand science better, I can surely help. 
With a Master in Science Education and a solid background in the Danish Educational System I can provide an approach to science that is more meaningful than the explanation students get in school. 
I am not a teacher in Physics or Chemistry, but besides my Master I have a Bachelor in Geography, Biology and Social Studies. 
Lessons times can be arranged to fit into your family schedule.
Let me know about your needs. 

Hold a California Teaching Credential in Biological Science and Social Science.
