Hatching Baby Chicks
The first science interaction that I remember was watching baby chicks hatch in an incubator in Kindergarten. Our class was given two dozen eggs and an incubator and every day, we made observations before and after chicks were born. This was such an exciting moment for me as it was my first time watching biology before my eyes. I loved that my teacher explained the stages of chick embryo development within our science lessons and she let us hold the chicks once they were strong enough. -
Testing Rocks and Minerals
In 5th grade, our class tested rocks on color, hardness, streak, luster, and cleavage. This was the first time I remembered using tools and materials to test something relating to science. I completed an observation record sheet with a group of students and for each rock, we completed the classification of each category. By experimenting, making observations, and making recordings, I was able to successfully classify rocks and minerals. This experience sparked questions about science in me! -
Launching Rockets
Our 6th grade teacher gave students a set of rocket designs for our project. We were to choose a design, build the rocket, paint it, and launch them as a class. The rockets were a foot tall and had many parts! We had guidance from our teacher for building it but ultimately, we had to put it together on our own following the design's instructions. Our goal was a successful launch by the end of the project. I loved expressing my creativeness while exploring the science behind a successful launch! -
Leaf Journal
I did a leaf journal where we had to find 20 different leaves within Illinois. We spent a quarter searching for leaves from different types of trees and pressing the leaves into the journal using newspapers, heavy books, and plastic binder sleeves. Within the journal, I had to provide the common and scientific name, place and date found, and the leaf itself. I LOVED this project. Not only did I learn about plants, but I spent time outside with my family. This project sparked my love for nature. -
Punnett Squares
One thing that I have always been curious about is heredity. When Punnett Squares were introduced in biology class my freshman year, I was so intrigued that percentages could be expected based on genotypes and phenotypes from genetic crossing. We analyzed alleles from plants, animals, and humans. I even had the opportunity to create Punnett Squares relating to my family tree. I am amazed that we can make these predictions based on the crossing of genetics and love to see the possible results. -
Frog Dissection
Freshman year, we were learning about body systems and were going to explore the organs of a frog. When my groups and I started incisions, we were shocked to see tons of black spots that looked like chia seeds everywhere-- it was a female! Once we scooped the eggs out we explored the anatomy of the frog, which was interesting to see the differences and similarities to the human body. This experiment gave me a hands-on experience that increased my appreciation for the complexity of organisms. -
Ice Cream in a Bag
My chemistry teacher taught us about exothermic reaction, which occurs when heat is released. Based on ingredients added and the instructions to make a chemical reaction, it was interesting following the steps and seeing physical property changes. Along with observations, I had to identify what occurred when certain ingredients mixed together. This was memorable because I was able to manipulate physical properties! I loved the hands-on activity and felt comfortable asking others for help too. -
Needs for Plants to Grow
In college, our professor had us grow bean plants. We had to use the scientific method and independent and dependent variables when adding or taking away the needs of the plant as it grows. One plant was provided all needs, one plant did not receive water, and one plant did not receive sun light. We had to observe the changes in plants to determine the importance of every variable. This experiment gave me a clear picture of what plants need to survive and it raised more questions about plants. -
Tin Foil Boats and Pennies
I have been discussing buoyancy annually with my students in science. One experiment that the students do is create tin foil boats and test its floating abilities in a water bucket. Then, students add pennies once they find the most efficient tin foil boat design. The students are to try to add 50 or more pennies in their boat before it sinks. This experiment promotes teamwork while brainstorming the best way to create a floating tin foil boat sturdy enough to hold pennies together. -
Earth Systems
In science we talk about ecosystems, which students learn about consumers, food chains, food webs, etc. Students participate in an ecosystem nature walk within our school grounds. They make observations with peers relating to food chains and interactive Earth systems. Students learn about biomes within this unit and choose one to write an essay on to apply their knowledge and research skills relating to the unit's concepts. This also gives the students the opportunity to demonstrate learning!
