What Is Biodegradable?

There's quite a bit in this physical science packet. First, how is heat transferred? Learners read a brief explanation of conduction, convection, and radiation before identifying common occurrences (with pictures) as one of the three....

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a activity on...

Composting is a great way to get children involved in recycling. First, they discuss how biodegradable products decompose to make compost. Then, they talk about what can and cannot be composted. They play a game similar to around the...

Teach young engineers that all machines, no matter how complicated or complex, are made up of just six simple devices with this hands-on physical science lesson. Using the included templates, students first create paper models of...

Looking for an interesting text to share the world of microbes with your middle school classroom? The edition contains explanations, worksheets, experiments, discussions, and links to outside sources for a true and complete...

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...

Discuss the difference between conduction, convection and radiation of thermal energy, and complete activities with your class by investigating the difference between temperature, thermal energy and the heat capacity of different materials.

The good thing about building this rover is you get to eat it afterwards. Pairs determine rover parts they want to include in their design based upon their cost and usefulness. The teams design their rovers, build them from edible...
