2. Don’t run
3. If glass breaks, tell a teacher and don’t touch it
4. Wear safety goggles w/ glass & chemicals

Question 6

Explain how neuroplasticity was shown in your experiment

Answer 6

In my experiment, both me and my partners attempts were lowest at trial 3. This relates to neuroplasticity because our brains got used to where the target is and right motion we have to do to hit it.

Question 7

Qualitative vs. quantitative

Answer 7

Qualitative means measuring something by sensory description, like smell, color, texture. Quantitative means measuring something by numbers, like cm tall, degrees Celsius.
