Parts of the Human Skin 3D Diorama Science Project Pop Up Craft Activity

By That One Cheerful Classroom

Make reviewing the parts of the skin fun with this engaging hands-on 3D diorama science craft project! Students learn about the skin layers and then decorate a shoe box based on what they learned! Students are responsible for decorating the box and putting a creative scene inside that represents the parts of human skin. Students love it when they get to do projects and make their learning come to life!

Here’s what you’ll get:

  • pre-colored pages for a quick cut and prep
  • black and white pages for students to color their own background and pieces, cut, and decorate
  • rubric for easy grading
  • research page for students to record their learning
  • planning page for students to map out how they want their diorama to look

What is a diorama?

A diorama is a three-dimensional scene built to illustrate a topic. Dioramas are small scenes created with layers of materials. A diorama can be made out of a shoe box or similar box that includes a variety of information and pictures about a topic.

Students create a diorama by cutting, coloring, painting, and gluing pieces inside the box to create a model that shows a situation, such as a historical event or animals in their natural environment. Students can be encouraged to add real features such as grass, sand, sticks, etc.

The dioramas do not come with specific assembly instructions. Students should learn about the parts of the skin first, and use the pieces within this resource to creatively build their own unique diorama! This is a fun way for students to learn and get hands-on with the lesson/topic.

Prep is quick and easy... print the pieces on cardstock for durability and let your students explore the water as an enrichment activity to your lesson plan.

TEACHERS LIKE YOU SAID…

⭐️⭐️⭐️⭐️⭐️ Madeline L. says, "Great resource to use when teaching young learners about the skin layers and their functions and components."

Natural Selection & Survival of the Fittest - Lab - Middle School Science

By The Science Cell

Are you looking for a hands-on, inquiry-based lab for your middle school students that demonstrates natural selection? This lab will do just that as it guides students to act as birds in a forest as they prey on skittles to see how the adaptation of camouflage helps a species survive. They will then collect data to see how the organisms with the fittest traits survive. The lab can be completed in one day and the graph and reflection questions will most likely take a second day to complete.

The simulation activity includes warm up questions, step by step instructions, a data table, line graph, and reflection questions. Students also use math skills to calculate population percentages and display them on a line graph.

Materials needed: skittles & green paper or green napkins (optional: polka dot napkins)

An answer key is included.

Your students will:

  • Engage in visual and hands-on learning
  • Apply knowledge
  • Practice concepts 
  • Collect data
  • Analyze data
  • Draw conclusions
  • Use math skills
  • Explore real world application of science knowledge

Animal Cell Collaborative Poster | Animal Cell Activites

By Jennifer

This Animal Cell Collaborative Poster promotes TEAMWORK and COMMUNICATION, while teaching students about the organelles in animal cells.

This activity includes 25 images that make up a large animal cell, meant to display on a bulletin board or on the wall.

Size is 53" x 39 "

All images include numbers so that students are using a consistent color code. If a student's image does not include a number, they will have to talk with their classmates to determine what colors they need to be using. This really encourages TEAMWORK and COMMUNICATION.

How to Use This Product (page included with purchase):

  • Print out the 25 images from the pdf document
  • Pass out the “Animal Cell Collaborative Poster Guide” that includes the color code
  • Once students have the coloring completed, arrange images according to the table included. The correct corresponding position can be found on the top left corner of each image
  • Staple the final product to a bulletin board. You can also tape your images to the wall

You and your students will be PROUD of your final display!

Matter "Mini" Labs

By Brittany Henderson

FOUR "mini" labs -or shortened activities- to reinforce or introduce concepts to students. I call these activities “mini labs” because they are simple activities that do not take the whole class period. They are also activities that are safe for use in the classroom and do not have to be done in a lab or with any specialty equipment or materials. I often use these demonstrations to lead into new content, that way as we cover material I can refer back to the things that my students have experienced first hand.

This particular lab focuses on introducing the following concepts:

Matter Takes Up Space

Two Substances Form a Mixture

Density and Volume

Change of State

(Indirectly the Properties of Matter)

Includes: teacher information, materials list, procedures, helpful tips for facilitating the activities and student handouts/lab sheets

Materials needed for these Mini Labs:

Balloons, Cups, Water, Sugar, Clay, Small Bowls, Paper Towels, Stopwatch, Chocolate Coated Candies
