Easy and Fun Biology Projects You Can Do with Preschoolers through 2nd Graders

Jan 29, 2018 12:00 AM

Kids love to touch things, don’t they? Whenever children are in the stores with their parent’sshoppers always hear the parents say, “Stop touching that!” or “Put that down!” Children just cannot help themselves; touching objects are how they learn. Fingers, especially the fingertips, have hundreds of nerves that are very sensitive and take in vast amounts of information about the item that child is feeling, sends it to the brain to process.Then, the child uses prior knowledge, known as assimilation, to help them relate to and identify the item.

The Biology projects mentioned in this post are great for youngsters because they are hands-on and focus on the tactile learners, which includes almost every student in your classroom. The projects include making and exploring spiderwebs, making a snowman, and Identifying seeds from fruits and vegetables.

Below are a few ideas to help bring science to life for your class.

Spiderweb Project – This project is easy, and kids will like working with the toothpicks to design their web. While you want to encourage them to create the web as the spider does, this project is also an excellent opportunity for them to design a unique web, within reason of course. Some items you will need for this project are:

  •  A spider storybook
  • Pen or pencil
  • Stick glue or Elmer’s glue
  • Toothpicks
  • 3 Bins
  • String
  • Construction Paper
  • Raw Spaghetti (broken into strips)
After you have read the Spider story to the students, take them for a walk outside, weather permitting, and find spiderwebs.As you count them, let the children observe them, but mind that the children don’t damage the webs. You may want to ask some questions while walking about. Some of the questions could be (1) How many sides does the web have? (2) Why do spiders spin webs? (3) What shape is the web? (4) What holds the web together? Elaborate on how spiders create their webs using their spinnerets, and the two different types of silk that are used. (5) Where is the spider? Is it quietly watching you? Once the class is back inside the classroom, pass out the construction paper and glue to each child. *NOTE: You should draw the shape of the spiderweb on the construction paper ahead of time. The toothpicks, pieces of string, and pieces of spaghetti will be separated into three bins ahead of time also.*Then, allow the children to choose their items to build the web. If the kids chose to mix up the items to build their webs, they might require a little extra help. Have the children secure their selected pieces onto the paper with the glue. Did they stick with the shape that was on the construction paper, or did some pupils go off the grid and design their web?

Variations:(1) Mimic how the spider builds its web through weaving two different colors of construction paper into a border. Thisis geared for children who are about 7-8 years old and have goodfine motor skills. (2) Students can also build a chain out of construction paper pieces to exemplify the strength of the spiderweb. 

Create an Adorable Snowman – This is another engaging activity for the class. It is a great lesson for teaching the parts of the body.The snowman activity is a great project from You can use the following items to make the snowman:

  • Glue sticks and Elmer’s Glue
  • Scissors
  • White tissue paper, cut into 1” squares
  • Paper Plates
  • Pencils
  • Wax paper
  • Template for the snowman’s hat
  • Wide Ribbon, cut into 12-18” strips
  • Construction Paper, various colors
  • Buttons 
Instruct the children to cut the construction paper into a rectangle. This will be the snowman’s body. Then, using the template, trace and cut out his hat. Place a large sheet of wax paper on the table or desk where the students are working. Place the snowman’s body on the waxed paper. Allow the students to decorate the hat with the ribbon and buttons, then glue it onto the top of the snowman’s body. Pour glue onto the paper plate. Take the 1” squares of tissue paper and wrap it around the pencil. Next, glue the scrunched tissue paper onto the construction paper that is for the body of the snowman. Direct children to do likewise until the entire body is covered. This technique creates depth and texture for the snowman. Use the cut pieces of ribbon as a scarf and ask the kids to “wrap” the snowman’s neck with it. Have students cut out and glue the round pieces of construction paper for the snowman’s eyes and buttons. Then, cut out a triangle from the ribbon for his nose. Set the snowmen aside to finish drying.

Productivity of Seeds for Different Fruits – Why do fruits have many seeds? Fruits have so many seeds to ensure their survival. But how can you tell if the fruit will be successful in surviving and generating more fruit? This project incorporates math with Biology. What a great way to combine these subjects.

  • Five different fruits (apples, tomatoes, green or red bell peppers, grapes, oranges, cucumbers, lemons, kiwis, or strawberries) – do not use seedless varieties
  • Cutting board
  • Sharp knife
  • Paper towels
  • Notebook
  • Toothpicks
  • Chart to make the graph 

Have children write the different types of fruit in their notebooks. Using the cutting board and sharp knife, cut the fruit into pieces being sure to expose the seeds. NOTE: *This step is only for the adult in the classroom.* Next, carefully take out the seeds and place them on the selected paper towels. For now, you may want to leave the seeds attached to the center of the fruits. If you have a cucumber, do not take out the seeds, instead, cut it into slices and place on the paper towel. If you have a strawberry, carefully remove the seeds with a toothpick and put them on the paper towel. Repeat this step until all the fruit is cut and the seeds are removed. Next, count the seeds and write the total in the notebook. Next, figure out the productivity of each fruit. An example of this would be if the cucumbers have a total of 100 seeds, and there were two cucumbers, then the productivity of the cucumber is 50 seeds per cucumber. Chart the productivity of each fruit in the notebook. Next, create a bar graph using the data. Students may draw the graph or use computer software to generate the graph electronically. Be sure to use the Y-axis for the number of seeds for each fruit. This should be along the left side of the graph. Once the children have completed their graphs, instruct them to share their finding to the class.

Variation:(1) You may want to create a large graph as a class using poster board or a large easel. Have the students use crayons or markers write the findings on the chart during the project. For more information about this project, please goto (2) If you wanted to add Language Arts to this project, have the students write a brief description of the project and their discoveries. They may want to tell what part of the project they enjoyed the most.

The projects mentioned above are fun for kids. Plain and simple, children like to be involved with activities,and these projects are functional, as well as educational. These are also great for homeschoolers because they use everyday items that are already laying around the house, and if you don’t have them handy, they are easy to find at the local craft store. So, have fun and enjoy doing these projects with the kids.
