8th Grade TCAP Practice 1

Atoms

100

Positively charged subatomic particles

Protons

200

Negatively charged subatomic particles 

Electrons 

300

DOUBLE POINTS!- Two subatomic particles that make up the nucleus 

Protons and Neutrons 

400

This is a charged particle due to losing or gaining electrons 

Ion

500

This is the name given to an ion that has more electrons than protons 

Anion

Forces

100

Two factors that impact the strength of gravity 

Mass and Distance 

200

One way you can increase the amount of electricity produced by a generator 

Increase amount of mechanical energy 

300

Other than adding a larger battery, how can you increase the strength of an electromagnet 

More coils 

400

Name this process: Adding smaller atoms together to form a larger atom 

Nuclear Fusion 

500

Three components of an electromagnet

Coil

Nail

Battery 

Waves

100

All waves move___________ not matter

Energy 

200

Two categories waves can be put into

Mechanical 

Electromagnetic 

300

This wave movement has properties of a crest and trough 

Transverse

400

DOUBLE TOTAL POINTS OR LOSE IT ALL These two properties would only be found on longitudinal waves

Compressions and Rarefactions

500

By determining the number of waves that pass through two points in a given amount of time you known the waves ________

frequency 

EM Spectrum

100

All waves on the EM spectrum have the ability to do this

move through empty space

200

Wave that carries the least energy on the EM spectrum

Radio Waves 

300

Wave that carries the most energy on the EM Spectrum

Gamma Rays 

400

Only wave on EM spectrum we can see

Light waves 

500

This wave has the longest wavelength of all waves on the EM spectrum

Radio Waves
