My budget has been somewhat limited (non-existent) this year, forcing me to get a bit more creative than usual. As with all things, I simply took it is a challenge to push myself and my students a little further.
This week, using leftover lab materials from years past (plus about $15 worth of Dollar Tree crafting supplies, jello and candy), my 6th grade class created 3-D Paper Plate Eukaryotic Cells AND Jello Cell Models! I must say I am impressed with my students’ ingenuity and enthusiasm with these two projects.
We started the week with a review of prokaryotic and eukaryotic cells, then illustrated and labeled an animal cell diagram. On Tuesday, I broke the 6th graders up into expert groups and assigned each team an organelle to research and later teach to their classmates.
On Wednesday, we used all of this background information and their diagrams to begin building our Paper Cell Models, and then used the same procedures to assemble our Jello Cells on Thursday.
I was apprehensive at first to attempt TWO messy, crafty activities back to back, but I think it provided necessary reinforcement for this completely new (to them) 6th grade concept. Plus, doing the Paper Plate cell first set us up for success with the main event…the Jello Cell.
Did I mention the students had a BLAST?
ExCELLent Eukaryotic Cell Models
Grade Level: 6th-10th | Duration: 90 minutes (each) | Content: Life Science – Animal Cells, Organelles, Eukaryotes
Academic Vocabulary: prokaryotic, eukaryotic, cell, organelle, nucleus, golgi apparatus, endoplasmic reticulum, mitochondria, ribosomes, lysosomes, vacuoles, cytoplasm, cytoskeleton
The Paper Plate Cell Model
Materials: (2) Paper Plates per student, tape or glue, scissors, plastic wrap or cello paper, (2) balloons per student, pipe cleaners, straws, beads, confetti, copy paper, ribbon. Optional: nerds, popsicle sticks, garland/tinsel.
If you really want the cells to pop, these two dollar store supplies took the project next level…vinyl dollar store table cloth to cover the back of the plate (pink and red) and gift basket dollar store mesh or burlap ribbon to use for cytoplasm/ribosomes OR to cover the front of the cell. You can also save mesh produce bags (like for oranges) if you plan ahead far enough.
Before we started crafting our Paper Plate Cells, I had students copy a list of organelles into their science journals. I included nucleus, endoplasmic reticulum, Golgi body, mitochondria, cytoskeleton, cytoplasm, ribosomes, and lysosomes.
Either of these two projects can easily be modified for higher grade levels with the addition of advanced structures, or simplified structures for lower grade levels.
Next, I showed the students what materials would be available to create their cells models. In their journals, I had them brainstorm what materials they wanted to use for each organelle and why. Once they had a completed list, they could come up and get their supplies.
- Cut a circle out of one plate. Cover the opening with plastic wrap or cello paper from the inside to create a viewing window. Put this plate aside until later.
- Use the other plate to begin building the cell model. Glue or tape the “organelles” into the model. Students may also use additional plastic wrap to represent the cytoplasm.
- Create labels or write organelle names directly onto plate.
- Place the other plate with the cut window over the finished model and attach with tape
After my students were finished, I attached string and hung them around the classroom!
Here is the project rubric (free).
The Jello Cell Model
- (8) 6 oz boxes of yellow, orange, or green gelatin per 20 students
- Hot/boiling water to mix gelatin
- 1 quart or sandwich size plastic bag per student
- Assorted dollar store dried fruits and candies to represent organelles (I used apricots, raisins, pineapple, big marshmellows, round and chocolate sprinkles, sunflower seeds, Sweet Tarts, sour strings, and Twizzler Bites)
Teacher Prep: Mix gelatin and boiling water in advance. I recommend pre-portioning the jello in 1/2 cup-3/4 cup portions in the plastic bags to save time, and refrigerate approximately 30 minutes to an hour before class.
I also put together a make shift “menu” to show on the document camera so the students could easily see their material choices.
For obvious reasons, this activity was a bit less structured than the Paper Plate Cell Model.
Again, I had students copy the list of organelles into their science journals to prepare them to select materials. As they did this, I sent a student to refrigerator to pick up the gelatin bags.
When students completed their list and reasoning for their choices, they came and picked up the jello bag and materials for their nucleus ONLY.
After adding the “nucleus” into the center of the jello, students wrote their names on the bags and I returned them to the fridge for about 30 more minutes to firm up a little more before completing the model. This made placement of the organelles go more smoothly.
Once the students had completed their Jello model, they were required to verbally describe the different organelles and structures to receive a spoon to eat their creation. Don’t forget to ask them about the cell membrane!
