What's Happening in Second Grade

How the Physical and Behavioral Characteristics of Animals Aid Their Survival

Second-grade students are studying the needs of plants and animals, as well as how these organisms interact with their surroundings to survive. Through their research on various animals, the students can explain how the physical characteristics and behaviors of these animals contribute to their survival. Congratulations to the young scientists for their hard work and dedication!

Interdependence, Seed Dispersal, and Pollination

Second-grade students began their new year learning about the interactions, energy, and dynamics of ecosystems. The essential question they are exploring is, "How do living things depend on each other for survival?" First, the girls worked in small groups to discover how plants and animals can change their environments. Next, the students identified the basic needs of plants and explained how a plant's parts help it meet its basic needs. Lastly, the second-grade students conducted a scientific investigation into the relationship between animals and plants, focusing on those that rely on each other for survival. They learned that animals assist plants in various ways, such as through pollination and seed dispersal. To demonstrate their understanding, students created models illustrating how their chosen animal helps plants. These models combined artistic collages with written descriptions explaining how the animal assists in pollination or seed dispersal.

Freeze Pops and a Christmas Challenge

This month, the girls completed their exploration of reversible changes in matter. They recorded their results in their science journals and enjoyed eating their refrozen treats! 

Next, the girls accepted a challenge to build Christmas trees using gumdrops and toothpicks. They were required to ensure that their trees had a sturdy foundation and that the shape came to a point at the top. Everyone enjoyed this festive STEM activity before the holiday break!

Reversible and Irreversible Changes in Matter

This month, the girls participated in hands-on exploration by testing various forms of matter to see if changes in matter can be reversed. They began by building with cubes and worked in pairs to create unique structures. Afterward, they reconstructed their designs in different ways, demonstrating that changes to the building blocks are reversible. To conclude their unit on matter, the second-grade scientists designed experiments to test how a freeze pop can undergo a reversible change. The girls began their experiments with frozen popsicles, wrote down their hypotheses, and decided which methods they would use to test them. They employed various techniques, including applying heat, using water, and placing the popsicles in the sun. Once the frozen pops melted, the girls returned them to the freezer to see whether the changes were reversible or irreversible. Stay tuned to find out the results!

Identify the Most Durable Building Material

This month, the second-graders continued to explore the properties of matter. Working in pairs, they analyzed data to identify which building material produced the strongest structure. The girls constructed two specific structures and tested their strength using crayon boxes. Each building had to meet specific criteria. Throughout the project, the girls demonstrated impressive focus and respect for one another. Excellent work!

Properties of Matter and an Observation Experiment

After learning about the scientific method, the second-grade girls conducted their first observation experiment. They researched background information, formed hypotheses, conducted the experiment, and are now gathering evidence to support their hypotheses. After completing the experiment, they will analyze their notes and record data to make inferences and draw conclusions. Finally, they will share and discuss their findings like scientists.

Additionally, the girls are learning about the importance of properties of matter. To begin this exploration, the second-grade scientists examined mystery bags to determine whether the objects inside were solids, liquids, or gases. Great work!

The Pretzel Challenge

What an exciting way to start the school year! The second-grade students participated in a fun and challenging engineering activity. Their task was to build the tallest free-standing tower using pretzels and masking tape. The girls worked in teams, learning how to communicate and support one another. This challenge required critical thinking and creative solutions. The students discovered that teamwork can make challenging tasks easier and more enjoyable! The girls demonstrated great perseverance and teamwork,  completing the pretzel build. They had a blast brainstorming ideas and overcoming challenges together. Excellent job, second grade! Teamwork and creativity made this challenge a great success.
