But First… Introductions

• Your Name (what you go by)
• Something about you that’s the same from last year
• Something about you that’s NEW - a hobby, an experience you had, a game you played, etc.

What is Biology?

Chemistry of Life

Day 1

Thursday August 3, 2023

Life, Animal Behavior, & Experimental Design

Why do we care what living things are made of?

Time for Isopods!

Observe the isopods

• Observe and gently move them with the paint brush to examine their anatomy and behavior.
• What do you notice about them? With your partner, write down your observations.

Animal Behavior: Isopods

Lab Time!

Scientific Sketching

Movement: Taxis vs Kinesis

Taxis - movement in a particular direction toward or away from a stimulus

Kinesis - random non-directional movement in response to a stimulus

What Does Our Data Say?

Tomorrow:

• Data analysis basics
• Animal Behavior Inquiry - Lab Design
• *Lab Part 2 on Monday

Before tomorrow – Day 1 Assignment on Canvas

• Read course info
• Student info form

WASH YOUR HANDS BEFORE YOU LEAVE, PLEASE!

Lab Design & Data Analysis

Why do we care what living things are made of?

Would you rather…

• Be trapped in a room with hundreds of crickets?

• Be trapped in a room with a snake?

OR

Graphing & Analyzing Data

Standard Deviation

• Measure of how dispersed the data is in relation to the mean.
• Approx. 2/3 of data is within 1 std dev of the average
• Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Standard Deviation

Standard Error of the Mean

• How GOOD is your data?
• Measure of how far the sample average may deviate from the actual average
• Measurement of trust in your average
• Dependent on
• standard deviation of the data
• sample size

In google sheets:

• Stdev / sqrt(count)

Day 3

Monday August 7, 2023

Inquiry Lab and Communicating Investigative Results

Why do we care what living things are made of?

Today’s Tasks:

Animal Behavior Inquiry: Complete part 2 of the lab, testing your team’s unique hypothesis.

Lab Report Guidelines: Read the guidelines, look over the template, and begin your group write up.

Mid-Class Meetings:

1. Share one experimental success and one struggle. Get feedback / ideas from your partner.

2. How do labs in AP Biology compare to experiments you’ve done in past courses? How are reports similar and different?

Upcoming:

• Tomorrow 8/8 – ASVAB during 1^st & 2^nd periods
• Team lab write up due by Monday 8/14
• Resubmissions due by Tuesday 8/22

Which One Doesn’t Belong?

You may choose ONE for each slide. Write down your choices and reasoning on a white board.

Measure Your Reaction Time!!!

Analyze!

• Analyze Rxn Time Data
• Copy sheet, use sheet to calculate, graph w/ error bars
• Practice Quiz on Canvas
• Chi Square AND Standard Deviation + Standard Error
• Graph your inquiry lab data

Enter your reaction time in the class spreadsheet on Canvas��“Confidence in Experimental Data”
