This science activity asks students to think like an engineer to design a toy built with at least one solid, one liquid, and one gas. It\u2019s a fantastic way to combine creativity and core science standards to make learning about the states and properties of matter tangible and fun!<\/p>\n\n\n\n<p>To address 2-PS1-2 and K-2-ETS1-2 in second grade, I designed an investigation for students to analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. Students were required to develop a simple sketch, drawing, or in this case a physical model to illustrate how the shape of an object helps it function.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"531\" data-pin-url=\"https:\/\/aroundthekampfire.com\/states-of-matter-stem-challenge-design-a-toy\/?tp_image_id=20110\" src=\"https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-1024x531.jpg\" alt=\"States of Matter STEM Challenge\" class=\"wp-image-20110\" style=\"width:531px;height:auto\" srcset=\"https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-1024x531.jpg 1024w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-300x156.jpg 300w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-486x252.jpg 486w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-768x398.jpg 768w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-1536x797.jpg 1536w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-2048x1062.jpg 2048w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-455x236.jpg 455w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-233x121.jpg 233w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-730x379.jpg 730w, https:\/\/aroundthekampfire.com\/wp-content\/uploads\/2025\/09\/solid-liquid-gas-toys-STEM-project-350x182.jpg 350w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p>The objective of this states of matter STEM challenge is for students to investigate how the properties of solids, liquids, and gases make them useful.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">States of Matter STEM Challenge Procedure<\/h3>\n\n\n\n<p>Show students the videos, <a href=\"https:\/\/www.youtube.com\/watch?v=CYqSGXeT59k\" target=\"_blank\" rel=\"noreferrer noopener external\" data-wpel-link=\"external\">How Toys Are Made<\/a> or <a href=\"https:\/\/www.youtube.com\/watch?v=hQy5uKUTdrg\" target=\"_blank\" rel=\"noreferrer noopener external\" data-wpel-link=\"external\">Where Toys Come From<\/a> to set the purpose and provide context for the investigation.

Allow them time to touch, move, and think about the properties of each item. Ask them to think about how they can combine a solid, a liquid, and a gas to make a toy that works.
