Pick up test on table 1 and hold onto it 3 minutes to make compost bin observations Find your data table to record odor and appearance Temperature is 28 degrees C
2
TOC: Unit 3 Force & Motion Date Lecture/ Activity/ Lab Page 9/22Vocab Foldable 1
3
What are some responses plants might have to different things?
4
Edu Smart Video – Plant responses
5
Get out your textbook and get started Vocab Foldable Pgs. 490-492 in your textbook You will have to read to understand and create your definition You will also need a picture that
6
Force is a push or a pull. Force gives energy to an object, sometimes causing it to: 1. start moving 2. stop moving 3. change direction
7
The way a plant reacts and responds to the force of gravity.
8
A plant’s response to light. It will bend toward the light.
9
A plant’s response to water—the roots will grow toward the water.
10
The hard outer covering of a seed which serves as protection.
11
The process in which the main root of the plant emerges from the seed.
12
A force exerted outward on a plant cell wall by the water contained in the cell’s vacuole. This force gives the plant rigidity and keeps it upright. Plants that lose turgor pressure will wilt.
13
A plant’s response to touch.
14
Any changes in an organisms environment that causes a response
15
Occurs when a force is used to move an object over a distance To calculate how much work is done: Work = force(f) X distance (d) The unit is called a JOULE.
16
A push or pull
17
Unit used to measure work (a Newton meter)
18
The unit used to show force (can be measure using a spring scale)
19
Equipment used to measure force in Newtons
20
A simple machine that is a straight, slanted surface; a ramp The longer the incline plane the easier it is to move the object.
21
A force that opposes motion between 2 surfaces that are touching EXAMPLES Sliding friction (ice skater) Rolling friction (bowling ball rolling down the lane) Fluid friction (pitcher throwing a ball)
22
The force of attraction between two objects Which famous scientist is responsible for the theory of gravity? ____________________ Hint- he also wrote the laws of motion.
