Finally, an electromagnetic spectrum lab that will get glowing reviews from your class! Explore the nature of light using red and blue LED sources and fantastic phosphorescent paper. Young scientists compare the effects of blue light...

Did you know light can decrease visibility? Light pollution absolutely makes it more difficult to see stars. Scholars build a simple magnitude reader to determine the magnitude of stars. They use these data to estimate the impact of...

If you have elodea and snails in your classroom aquarium, or if you have access to a pond with these organisms, your young biologists can set up a controlled experiment to determine how certain ecosystems respond in light and dark...

Is the ocean blue at all depths? Nope! Explore the science behind the light spectrum in deep, dark waters. The activity recommends watching The Blue Planet: Open Ocean—The Deep, but it's not integral, or you can substitute another clip....

Turn your classroom into a greenhouse with a instructional activity on plant growth. First, investigate the different parts of seeds, identifying the seed coat, cotyledon, and embryo. Then plant the seeds and watch them grow!...

Are you looking for lab sheets to go with your class experiment on plant response to light? You are no longer in the dark! This is a lesson that was written for a unit on light, but could easily be used to demonstrate plant behaviors in...

Budding biologists often ask how scientists know what they do about different topics. In the lab described here, they have a chance to find out first-hand about the requirements for photosynthesis. Three sequential investigations are...

How does chemistry help deep-sea explorers? Part four of a five-part series of lessons from aboard the Okeanos Explorer introduces middle school scientists to technologies used in ocean exploration. Groups work together to analyze data...

Science is magic that works. Magical color-changing beads and a coffee can that follows voice commands are just two examples of magic tricks that rely on science. After completing a hands-on activity and an experiment investigating the...

Searching for a simple igneous rocks experiment to assist pupils with rock classification based on texture and composition? In the activity, pupils view multiple rocks in various ways to determine texture and composition. They then...

Using this resource, your team of green thumbs discuss why plants are a part of a healthy diet and the different ways they are used in daily life. They then observe the characteristics of different seed as they attempt to match...

For this transition metal worksheet, high schoolers are given equations for transition metals and their ions. Each equation shows the changes in the colors of the ions when heat, salt, or other substances are added to the metals.

How does the color of a surface affect the heating of the earth? Middle school science classes experiment with color and surface albedo to determine the relationship. The website has tabs for an overview, teacher's instructions,...

What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...

Pupils compare the temperature change in a closed and open box as a demonstration of the greenhouse effect. 

Where does all the heat go when the sun goes down? An interesting lesson has learners explore this question by monitoring the infrared radiation emitted over time. They learn that hot spots cool more quickly that cooler spots.

Young atmospheric scientists create models of an atmosphere with and without clouds to determine the effect of cloud cover on Earth's temperatures, as well as figuring out whether dark or light surfaces absorb more energy. You may wish...
