Protein Synthesis Activity

One of the most challenging topics for Biology students is protein synthesis. This Protein Synthesis Activity forces to dive into the content and develop an understanding of the process. They also have fun doing it!

In this protein synthesis activity, students must create a skit or a role play of the process of protein synthesis. Students must describe both transcription and translation throughout the skit.

Protein Synthesis Activity Requirements

This activity provides students with rubric to guide them through the development of their skit. Students are required to use the following terms throughout their presentation in some way:

  • DNA Molecule
  • Nucleotides
  • Amino acids (make sure they are attached to the correct tRNA)
  • RNA Polymerase
  • mRNA (codon must be mentioned)
  • tRNA (anticodon must be mentioned)
  • rRNA (Ribosome)
  • start codon
  • stop codon

Students always have great discussions as they talk through the process of making their skit about protein synthesis.

Sometimes groups get stuck and are not sure where to begin. When that happens I show them an animation. They can watch it as much as they need in order to develop an understanding of the process of protein synthesis and apply it to their skit.

To help ease the fear of presenting in front of the class, I also offer students the opportunity create a video presentation instead of presenting in class. It is some extra work but some student are glad to do it instead of presenting in front of the class.

Sometimes students do not equally participate. In this activity, all students are required to have an equal speaking part and it is in the rubric. I also tell students that they may lose points as an individual if they do not “pull their weight” in the activity.

Props for Protein Synthesis


Skits have props. You definitely need to give students a time limit on prop building or they will be building forever! Students can bring in their own supplies or you can provide the supplies.

In my classroom, I have a bin of random items that I collect from old kits, packing materials and random items I find that might be able to serve as a good model building materials.

My students have created some pretty amazing presentations using this protein synthesis activity. I hope your students enjoy it and it helps them learn the process of proteins synthesis as well.

Punnett Square Challenge

Recently, my class was finishing up the unit on genetics and learning how to do a variety of punnett squares  and  I knew I needed to create a better way to review this concept.

Inheritance Patterns: Punnett Squares

So… I created this Punnett Square Challenge that my students love.

Prior to completing this punnett square activity, students should have had exposure to examples, of complete dominance, incomplete dominance, co-dominance, multiple alleles and dihybrid crosses.

After students have had some practice with  punnet squares, this activity will serve as a review or a great gauge for \their understanding of the content.

In this activity,  students will complete each punnett square (1 through 6) in order.

Student will only receive one punnett square at a time and will only get the next one when they have correctly completed the preceding punnett square.

I have found that students generate great conversation when working together to complete these punnett squares, although it can be done independently.

Each new punnett square will add a degree of difficulty as they progress through the activity. I walk around with folders that contain the problems. As they get them correct I give them the next problem.

If students complete the activity within  first or second I offer them a homework pass or bonus points. I have done this as a race and timed and both way worked well. The homework pass incentive takes their effort up a notch.

Student always enjoy this and the discussions that take places are amazing.

6 Tips for Using a Biology Curriculum

If you are reading this post you are either using our full biology curriculum or thinking about using it. The

Tips and Tricks for Using the Biology Curriculum

Tip #1-Read the Lesson Plans
Be sure you are looking over the lesson plans to see how the plans and activities are used. You will find tips throughout the plans that are specific to the activities, classroom management, differentiation, grouping and activity instructions.

Tip # 2 -Differentiate
In the lesson plans, there is a section at the bottom designated for some suggested differentiation approaches and additional activity extension ideas.

The best part of using this curriculum is that it allows you to easily differentiated and make adjustments if you desire! How?Using this biology curriculum gives you time! Time, you are now able to use to hone in on YOUR students and find what works best for YOUR class and students.

Making adjustments and spending time to add the extra touches  that suite your class are now done without the stress of worrying about having a plan in place. You have a plan. Now, instead of building or finding resources that are aligned you can differentiate your instruction to better meet the needs of your students.

Tip # 3 -Review Assessments Prior to the Unit

If you intend to use the assessments provided ensure that you preview them prior to teaching the unit and revisit the assessment regularly throughout instruction (especially direct instruction) to ensure you are better able to help your students hone in on the information you will be assessing/find most important.

Tip # 4-There is Wiggle Room

Do not be afraid to shorten or lengthen the time frames that are given. When looking at the Scope and Sequence you can see there is time built in for reteaching and regular school interruptions. Also, take a look at your state standards to see exactly what topics need to be covered. Some Units are included in this curriculum because they were requested and may fit one states standards but not yours. For example, Classification is not part of my states standards. It is included. It is also organised so it reviews previously covered content while teaching new content. In short, there is wiggle room. Look at the Scope and Sequence and see where you can buy time if you need to.

Tip # 5-  Enthusiasm = Engagement from Students

Regardless of how amazing a lesson is if you are not prepared, organized and excited to deliver it, it is unlikely your students will be excited to learn it. Enthusiasm for the content (even if it isn’t your favorite topic) goes a long way at drawing your students in. You are on stage everyday. Have fun with your job. If you are having fun and are happy, your students will be too. I understand it is not easy to maintain a high level of enthusiasm 100 percent of the time but dig deep and try to as much as possible.

Tip # 6- Use the Community of Teachers!

We live during an amazing time. I recall teachers having to keep track of their grades by penciling them into their paper grade books. Technological advancements  now allow us to collaborate with each other from all around the world. You have access to tons of teachers who are all using the same curriculum!  Reach out, share and grow as a professional!

Reteaching Strategies for Biology

Before discussing reteaching strategies for biology it is important for you to understand that there is not a “silver bullet.”

Do not let that deter you from trying to find what works best for YOU and YOUR students.

There are several factors to consider when deciding on how to reteach your students.

Finding time for reteaching

  • When will the reteaching take place?
  • Are you willing to come in early or stay late? (It is okay if you are not able to)
  • Is there a time period during the day that is designated for this within your schedule?
  • Can you reteach students during your lunch period? (not ideal, but could be an option)
  • Is your school/district willing to compensate you for arranging sessions after school or during the evening?

Some unique ways to find time:

  • In school blitz sessions. Depending on your school, their flexibility and emphasis on test scores this idea may or may not go over. I have seen this be fairly successful for second time test takers. The day of the test students do not report to class at all. Instead, they report to a morning blitz sessions where one or several biology teachers rotate students through hands on stations that refresh their memory on specific content standards. Student then eat lunch and take the state test.
  • If you research podcasts (Bozeman, CrashCourse, Khan Academy, Amoeba Sisters) and have students complete assignment on their own to earn something (examples below). This is not the ideal circumstance since it is kind of like homework and it is likely these students were not doing their homework.

Strategies for Reteaching Students for the Sake of Meeting the State Biology Testing Requirements

I hate even writing the line above but the reality is that states require students to pass exams for graduation. With that, it is your job to help them be as successful as possible even when the students are brought to tears by the thought of taking the biology test. (I have witnessed this on many occasions)

How can you possibly do this effectively?

The first thing you need is a “carrot” or something to make the students want to come and learn and not just because they have to pass the test.  I know what some of you are thinking. How can I offer these kids a “carrot” and reward these students who are not getting it right the first time?

I understand the perspective but we have to look at the situation through a different lens.

Not all student have an affinity for science, biology or even school for that matter.

Not all student are coming to you from the a world of love, support, structure and some may even be battling health and family issues you are not  aware of.  Learning does not coming easy to all students.

Check out our Full Biology Curriculum.

 

Motivational Ideas for Students Who Attend and Participate FULLY

The ideas below   I have used in the past that have worked well. They were all funded and supported by the school/district and not the teachers.

  • Offer points to students just for attending and participating in the sessions.
  • Create punch cards with your states or the NGSS standards on them. Each sessions student attend they get their card punched. If they complete all of their sessions they get something (examples below).
  • Pizza Party for “X” number of sessions attended
  • Graduation fees waived
  • 2 extra graduation tickets for family (if your school does this)
  • Each session attended is an entry into a drawing for a gift card
  • Each session attended could increase their test/ class grade by “X points/%”
  • Attend “X” number of sessions and get to go on the Gaming Truck. Yes, that is a tractor trail truck that has video games systems in tow in addition to sumo suits! This happened. The students were humble and grateful.
  • Reach out to local businesses and ask for support (gift cards and even free passes)

Reteaching Biology Content

When it comes to reteaching the content, especially for the sake of passing the state assessment, less is more.

Cut out anything that goes beyond the state standards and hone in on only what the students will need to know.

Try a different approach. The first time did not work so well. Do something new. Aim for hands-on activities and get the student to talk about what they are doing.

Strategies

Vocabulary

  • Hit the vocabulary hard. Have students use the key terms.
  • Use Quizlet Live to help students practice vocabulary.

Scripted Teaching with a Diagram

  • Provide diagrams and a script of a processes (protein synthesis, photosynthesis, cellular respiration ect..)  and have student read the script of the process while using their finger to follow the process on the diagram. Have students  teach each other the processes in the same manner. Start will a script and then take the script away.

Hands-on Activities

Small Groups

  • Use small group or one on one direct instruction to get started.
  • Set up stations that cover content standard or topics and rotate students through the stations.

Questions Review

  • Print sample constructed response questions with the answers. Each students gets a different question. Have students partner up with each other and ask each other questions on their cards. If the students do not know the answer the other student reads the answer and then asks the student again. When they are done the find someone with a different questions. Student do this until the have rotated through each question. They will then have had exposure to a whole bunch of different questions and answers. This strategy works well for helping students understand what the answers for constructed responses should sound like.

Microscope Lab

In this microscope lab activity, students will learn how to use a microscopes and prepare slides for viewing. Your student are going to love this microscope lab.

Full Biology Curriculum

For this microscope lab, your students will  gain a better understanding of how to easily find a specimen using a simple procedure that is included as a bell ringer in our Full Biology Curriculum. 

In the microscope lab bell ringer, students look at the step below out of order and try to place them in the proper order. After going over the proper order listed below, students can then use the procedures as a guide as the complete the microscope lab.

microscope lab activity

Step for using a microscope:

  1. Plug in and turn on the microscope.
  2. Lower the stage so it is farthest from the objective lens.
  3. Adjust the objective lens to the lowest magnification
  4. Place the prepared slide on the center stage
  5. While looking into the ocular lens, slowly move the stage towards you using the course adjustment knob until the sample comes into view.
  6. Use the fine adjustment knob to focus your image better. You can also adjust the diaphragm to let in an optimal amount of light.
  7. Move to a higher power if necessary. DO NOT LET THE OBJECTIVE LENS TOUCH THE SLIDE when switching to a higher power. You may need to lower the stage.

You can download a copy of the microscope lab activity here . This is a great lab activity to introduce your students to using the microscope. This is written in a way that you can step back and just let the students have fun and explore the microscope.

 Some Hilarious Misconceptions

Full Biology Curriculum

When doing this microscope lab  I love stepping back and listening to the students and answering their questions.

I created a post on my Facebook Page about some of the comments teachers make when students are using a microscope. Many of my followers loved this post and added their own comment that you can read below.

[Never assume using a microscope is intuitive for students.]
If you need a good laugh read below.

Frequent quotes of Biology teachers to their students using microscopes:

“You may want to turn on the microscope, it works better that way”

“Are we looking at stars?, No?…..then this is a microscope”

“Hmm it seems as though your nose piece is not in the proper place”

“Yea….I am not surprise you do not see anything, you have not placed anything on the stage to view yet”

“Totally just an air bubble and not a crazy new species”

“That light is broke? It seems like it just needs to be plugged in”

“Stop screaming… it is just your eye lashes!”

“Hmm can’t see anything on the slide? Why don’t you put that dissecting microscope back in the cabinet and grab a compound microscope”

“You have to start on low every time”.

“That’s the edge of the coverslip”

” Coverslips cover. We don’t make slide sandwiches.”

“That’s not a coverslip, that’s the piece of paper that keeps the coverslips separated in the box.”

“Yes, there is a line in there. It’s called a pointer!”

“Of course you can’t see anything now. You zoomed into a blank spot on the slide. You have to MOVE your slide so the specimen is dead center.”

….as kid holding slide up to light on the ceiling ” I promise there is something on the side, it’s microscopic you won’t see it that way”

“Turn the little knob if you want to see it better.” “If you turn down the light you’re gonna see more detail” “”move the slide slowly the OTHER WAY” “you’re not Dexter use a real coverslip”

“The drop of pond water goes under the coverslip, not on top of it!”

” The slide goes under the clips, not on top.”

“Losers Can’t Have Fun! Losers – Low power
Can’t- Course Adjustment Knob
Have -High Power
Fun – Fine Adjustment Knob
It’s how we teach the order of how to use a🔬! Kind of awkward when admin walks in, but they remember! 🤣”

“The specimen has to be thin enough for light to pass through it, that’s why all you can see is a black blob.”
