In this web-based application from Illuminations students must sort shapes based on the categories of the Venn diagram. Users can choose the categories from a drop down menu. The application includes instructions and exploration steps.

This chemistry lesson uses Sharpie Markers, rubbing alcohol and t-shirts to make a exciting tie-die looking t-shirt

This activity is a hands-on activity where students learn about polymers and the science of plastics, while making shrinky dinks.

Student teams make polymers using ordinary household supplies (glue, borax, water). They experiment with the semi-solid material when warm and cold to see and feel its elastic and viscous properties. Students will begin to understand how the electrical forces between particles change as temperature or the force applied to the substance changes. Is it a solid, a liquid, or something in between? How might it be used?

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.

Is it a tumor? Magnetic Resonance Imaging (MRI) can tell. Your head is full of tiny radio transmitters (the nuclear spins of the hydrogen nuclei of your water molecules). In an MRI unit, these little radios can be made to broadcast their positions, giving a detailed picture of the inside of your head.

This lesson has activities where students will learn about buoyancy and explore how hot water rises and cold water sinks. As an extension and real-life application, students will see that glacial run-off is occurring at a rapid pace and the cold glacial water could potentially change ocean currents thus influencing global climates.

This activity is a classroom lab where students learn that cold water is denser and hot water is less dense than room temperature water. Students perform an experiment and relate to their background knowledge to make conjectures.

This activity is a classroom experiment where students participate or observe that different densities of liquids will yield different results in a sink-or-float activity.

Students explore and experiment with various objects to find which materials will float or sink. They record predictions and results, and generate ideas about the properties of materials that float or sink.

This lesson will extend the learning on rocks with the Foss kit, Pebbles, Sand, and Silt to include soil. Students will perform the soil sifting activity like the one designed for rocks in the Foss it. Through their work, students will complete a Venn diagram of soil and rocks as a class.

Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses ‰ŰÓ sight, sound, smell, texture and taste ‰ŰÓ to identify the other characteristics of each item.

Students will explore with solids and liquids to discover what density is. Students will be involved in small group experiments and a full group experiment. Observing, predicting, exploring and discovering are all included in this lesson.

This guided inquiry lesson allows students to make explore with materials and draw conclusions if they are a solid or liquid.

This activity is a classroom activity where the students move through learning stations to explore the properties of solids and liquids.

This is a lab activity where students will investigate solubility or miscibility of eight substances with water.

This activity is a small-group activity that makes students learn the subject matter of aqueous solutions (colloids, suspensions) and phase changes by writing a children's book. Learning by teaching.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors. Learners can use this as a tool to study the properties of spherical mirrors while creating colorful mosaic reflections. This is a great optics activity to use during the holiday season or any time of year.

This activity allows students to brainstorm investigable questions, conduct an experiment, and communicate the results related to our invertebrate animal study; specifically sponges and absorption. (Lesson is based on an original activity from "Porifera's Porosity", Holt Science and Technology - Animals, Holt, Rinehart, and Winston 2002, pages 50-51.)

In this mini-lab students will use chromatography to compare the mobile phase and the stationary phases of different inks used in marking pens. They will also determine the polarity of the solvents and inks. Finally, the students will use their calculated information to solve a crime.
