Chemistry stars experiment with metals to observe reactivity with salt solutions. They test magnesium, zinc, iron, and copper by immersing them into different solutions and observing for changes. A separate set of data tables is...

Step-by-step procedures are outlined in the learning exercise and calculations for junior chemists to perform in their science journals. This laboratory exercise is intended for experienced chemistry learners.

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

Sometimes liquids just don't get along together. A fun experiment has scholars determine whether various liquids dissolve in water. They pour isopropyl alcohol, vegetable oil, and corn syrup into cups of water to see which ones mix well...

Learn how to record observations about the wildlife in your community by constructing a field journal.

Students will investigate leaves by using their five senses and journaling their findings in this lesson. Journal will record information in a matrix to enable students to see the how things are related.

Being field scientists, students will explore a wooded area in their community and journal about their observations. Students will collect information about producers, consumers, and decomposers in the ecosystem. They will then construct...

Get students observing the environment around their school with this activity. In this lab experiment, students keep a journal containing written observations and digital pictures of how local flora and fauna change during the school year.

Take the design challenge to make a wave machine with simple materials on this site. Site contains a design challenge and an interactive journal to document the challenge. Find a video with an example of one way to make the wave machine.

Students will study native plants by creating a herbarium used in plant identification. They will also complete some leaf rubbing to put in their journals. This activity is part of a series of labs about plants.

Conduct a series of virtual experiments using basic, acidic and neutral household liquids. Draw a conclusion from the results collected in an online lab journal.

As part of a unit on gathering data about the weather, this lesson features instructions for making a simple weather vane.
