Good Morning!Friday, 12/10

Your “Modeling Transpiration” lab was scheduled to be turned in today.

Hang on to them until Tuesday, I will collect them when I return (lucky ducks if you did not get it finished!).

Collect your data & make observations.

Don’t forget to water your plants!! Adding water is a control variable you

should be considering. Make sure you add the same amount of water to each of your plants.

STEP 5: Data Collection

3-D LEAF MODEL 5th period – Take out your

3-D leaf model that you have completed so far.

6th period – pick up the cut outs to make a 3-D model of a leaf.

3-D LEAF INSTRUCTIONS Cut out the leaves on both pieces of

paper. You should have 2 leaves: Wait to cut out the arrows!

Set the leaves on top of each other so it looks like 1 leaf.

Fold over the top leaf at a diagonal

3-D LEAF INSTRUCTIONS

Draw a line on the leaf where the top leaf is folded over

3-D LEAF INSTRUCTIONS

Glue the two leaves together at the bottom of the leaf (put glue ONLY below the diagonal line you drew)

3-D LEAF INSTRUCTIONS

Glue

Draw in the veins on the outside of the leaf and label.

3-D LEAF INSTRUCTIONS

Open the leaf and draw the inside:

Color and label all the parts:

3-D LEAF INSTRUCTIONS

Label your arrows: 2 of them SUN 2 of them WATER 2 of them SUGAR 2 of them CO2

(carbon dioxide) 1 of them O2

(oxygen)

3-D LEAF INSTRUCTIONS

Color your arrows SUN = yellow WATER = blue SUGAR = pink CO2 = orange O2 = purple

Cut your arrows out

3-D LEAF INSTRUCTIONS

Add 4 arrows to the top of your leaf:1. CO2

2. SUN3. SUGAR (flows

through the veins)

4. WATER (flows through the veins)

3-D LEAF INSTRUCTIONS

Add 5 arrows to the inside of your leaf:1. SUGAR (flows

through the phloem)2. WATER (flows

through the xylem)3. SUN (enters into

the chloroplasts)4. O2 (exits through

stomata)5. CO2 (enters through

stomata)

3-D LEAF INSTRUCTIONS

Notice how the oxygen and carbon dioxide arrows are going through a stomata in the dermal tissue of the leaf? If you need help with

this, have Mrs. C or Mrs. L help you make those cuts.

3-D LEAF INSTRUCTIONS

Write your name on the back of your leaf.

Hang onto it until next class – I want to see them!

3-D LEAF INSTRUCTIONS

PASS BACK PAPERS When you finish, ask the sub if you can

help pass back papers to the rest of the class.

Organize your papers in your binders MEANING – put them in the correct divider

and hook them into the rings of your binder!!!

We will be doing a “shake test” soon!!
