🌎 Unit 5 Bundle: Weathering, Erosion & Earth ChangesNGSS-Aligned | Hands-On Science | 2nd Grade STEM Curriculum DescriptionDig into Earth science with Rocky the Raccoon! In this hands-on STEM unit, students become Earth Investigators as they explore how wind, water, and time shape the land through weathering and erosion. Through engaging investigations, design challenges, and real-world connections, students will: Observe how wind and water move soil and change landforms Investigate how rock

Preventing Erosion STEM Challenge – Unit 5 Week 4 NGSS-Aligned | 2-ESS1-1 & 2-ESS2-1 | 2nd Grade Weathering & Erosion In this hands-on STEM challenge, students move from understanding erosion to thinking like engineers — designing and testing solutions to stop soil from washing away. Students investigate a real-world erosion problem (soil washing away under playground swings) and apply the engineering design process to slow, block, or redirect moving water. This week strengthens: Cause-and-eff

Keep your STEM lessons engaging and hands-on!In Week 2 of Unit 4: Interactions in Ecosystems, students join Buzz the Bee to discover how seeds move and why dispersal is important for plant survival. From wind and water to animals and gravity, learners will investigate the many ways seeds travel in nature. This resource includes: - Seed Travelers Sort – Cut and sort seed picture cards into dispersal categories - My Traveling Seed – Draw or model a seed moving in nature with sentence frames

Grow student curiosity with this complete Unit 3 STEM Curriculum Bundle: What Do Plants Need? from the Little STEM Explorers series! With Petal the Panda as their STEM guide, students explore how plants get what they need to survive and thrive. They observe, investigate, and design creative solutions through engaging STEM activities that bring the science of living things to life. This bundle includes Weeks 1–4 plus the Unit 3 Assessment Pack, giving you everything you need for a full month

Get your students buzzing about science with Unit 4: Pollination & Ecosystem Interactions from the Little STEM Explorers series! With Buzz the Bee as their STEM guide, students explore how plants and animals depend on each other through pollination and seed dispersal. Each week blends inquiry, design, and creativity for a truly hands-on, NGSS-aligned learning experience. This bundle includes Weeks 1–3 plus the Unit 4 Assessment Pack, giving you everything you need for a full month of engagin

Bring science to life in your classroom with this complete Unit 2 STEM bundle: Heating & Cooling from the Little STEM Explorers series! With Blaze the Bunny as their guide, students explore how heat and cold cause changes in matter, investigate which changes are reversible or irreversible, and design creative solutions using the engineering design process. This bundle includes Weeks 1–3 plus the Unit 2 Assessment Pack, giving you everything you need for a full month of hands-on, NGSS-aligned

In Unit 5, Week 2, students move from observing land change to investigating how water actively changes the land through a guided, hands-on STEM investigation. With Rocky the Raccoon as their guide, students plan, test, observe, and explain how moving water can reshape soil, rocks, and landforms. This week builds directly on Unit 5, Week 1 by shifting students from image analysis and discussion into cause-and-effect testing, evidence collection, and scientific explanation—without requiring

Little STEM Explorers – Unit 2, Week 2: Heat & Cold in Our World (NGSS 2-PS1-4)Explore how heat and cold can change everyday materials in this engaging, hands-on science pack! This week-long resource is part of our full-year Little STEM Explorers second grade curriculum. Students investigate reversible and irreversible changes through experiments, design challenges, and rich discussion prompts. This resource includes everything you need for meaningful instruction aligned with NGSS 2-PS1-4.

In this Buzz’s Winter Survival Challenge, students become young scientists as they test which materials act as the best insulators to help an ice cube stay frozen — just like animals staying warm in cold weather. Students will observe, predict, test, record, graph results, and reflect while learning about insulation and how animals use different materials to survive winter. This hands-on lab encourages curiosity, collaboration, problem-solving, and evidence-based reasoning — all essential scien

Warm up your winter STEM lessons with Mira the Mouse and her cozy Hot Cocoa Mix & Measure Lab!In this hands-on science and engineering investigation, students explore how temperature affects how solids dissolve in liquids. From predicting and mixing to observing and analyzing, learners follow Mira’s guided steps to think like real scientists. Aligned with NGSS standards (2-PS1-4) and grounded in Science and Engineering Practices (SEPs), this engaging lab blends scientific inquiry with creati

Keep your STEM lessons engaging and hands-on!In Week 3 of Unit 4: Interactions in Ecosystems, students join Buzz the Bee to explore the amazing role pollinators play in helping plants survive and grow. Learners will investigate how bees move pollen, model the process through hands-on activities, and reflect on why pollinators are essential for life. This resource includes: Pollination Anchor Chart & Vocabulary Cards – Build background knowledge with Buzz the Bee Cause & Effect Page – Explore w
