Van
De Graff Presentation Solutions
1.
Protons -
nucleus
Electrons –
outer orbits
Neutrons –
nucleus
2.
Insulators hold on to their electrons tightly while electrons can easily move
through conductors
3. Charge imbalance
that occurs when 2 materials are rubbed against each other
4. Negative
5. 9
6. See
diagram below
7. Repel
8. The
electrons in our hair are attracted to the positive charges accumulated around the
dome. Therefore, the positive charges in our hair repel against each other,
causing it to stand
9. During a
storm, clouds come together and harsh winds rub ice and dirt together,
stripping electrons and causing a massive positive charge buildup. Therefore,
electrons from the ground get transferred up
10. The
ground has infinite electrons. The Van De Graff strip electrons from our bodies
but we get the electrons back from the ground, creating a circuit with no
charge imbalance. However, plastic is a good insulator which allows us to
accumulate the positive charges in our bodies
