A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Reinforce the concept of one-to-one correspondence with a Valentine's Day-themed counting and color sorting activity. Scholars sort foam hearts by color—red, orange, yellow, green, blue, and purple—then count and place them on a number...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

How many classroom objects can your learners identify? Use a set of activities based on object recognition and color matching to help young kids use their observation to learn new vocabulary.

Can you eyes be fooled into seeing colors that aren't actually there? Budding scientists view a presentation that addresses this topic. They explore how their eyes interpret color through the retinas and messages sent to the brain. They...

Class groups bring feeling words alive by creating a poster that illustrates with images and colors, but not words, the feeling conjured by the word. The posters are then combined into a mural for the classroom wall.

Teacher's notes, a materials list, detailed procedure, tips, and extension ideas are all included to make teaching this lesson on photovoltaic cells a sunny spot in your day! After some brief background reading, physical science...

This Labor Day, provide class members with a variety of engaging worksheets offering games, word work, and more! Here, you'll find a game of tic-tac-toe, word puzzles, a coloring sheet, crafts, and vocabulary practice.

Physical science investigators mix sugar and food coloring into different cups of water and cooking oil to compare how the solid and liquid behave in each. As the introduction to this unit on dissolving, it is relevant.

Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing...

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Middle schoolers have a bushel of fun as they engage in activities and research core facts about apples. Packed with suggestions for in-class activities and out-of-class research, the colorful 6-page packet is sure to satisfy hungry...

Color, color, everywhere. As part of a three-week study of color, kindergarteners create animal color cards, design pages for an class animal book, populate an underwater scene with colorful fish, and invent and name a new color. 

You can sing a rainbow with a fun set of color-themed activities. Kids learn a song, match colors to objects, and jump up and down as they practice their color recognition.

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer. 

Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Test scholars' knowledge of addition facts with a festive worksheet that makes adding a two-person game. Pairs examine a grid of numbers to locate and color addition facts. Last person to color three squares wins!
