- Mix Jello ingredients.
- Let Jello cool at room temperature.
- Pour the Jello into the ziplock bag.
- Seal the ziplock bag.
- Place the ziplock bag into the refrigerator.
- Let it chill for about 3 to 4 hours in the refrigerator.
- Remove the Jello from the refrigerator and open the bag.
- Use a finger to insert the large grape into the center.
- Reseal the bag and then put the bag on a flat surface.
- Observe its shape as it is now.
- Gently squeeze the bag.
- Observe as you squeeze the bag.
- Place one small piece of tape on the front and back of each penny.
- Use the pen to write a capital E on one side of each penny and a
lowercase e on the other side.
- Use the pencil, ruler, and paper to prepare a chart.
- Stretch the towel out on a table.
- Hold both coins in your hands and shake them back and forth
several times, then toss the coins together over the towel.
- Put an X on your chart under "Trail 1" and next to the letter
combination showing coins.
- Toss the coins three more times, recording each letter
combination under Trail 1.
- Repeat steps 5 through 6 two more times, recording the results of
- Sort out the different pieces.
- Connect the different pieces to form a double helix.
- Cut out the four pages from the book.
- Looking at the inside of the model score along all score lines.
- Cut out precisely and fold into hill and valley.
- Fold as it is indicated and crease firmly.
- Glue all 8 pieces together using the letters A through G in
alphabetical order to make a single large net.
- Crease paper and check how the paper folds to form the double
- Start gluing with flap number 1.
- Work in numerical order from 1 to 13 until the double helix is
Students will be assessed on the following items:
- journal writing entries
- examples of cells
- model of double helix and nucleotide models
- oral and written presentation of their group report
