The Checks Lab

This very thorough lesson plan has young scholars collect all ingredients necessary and work in pairs to make ice cream using plastic bags. They take temperature readings and record them on the chart as well as record findings on the...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

Teach your exercise enthusiasts to read their pulse rate at the radial artery and multiply by four to calculate beats per minute. Learners perform a variety of activities, recording their heart rates after one minute of each. Though this...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

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...

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

Students explore the world of the very small using a Flash plug-in Virtual Electron Microscope. They complete and discuss an activity in which unknown samples are placed under the computer simulated microscope to determine where the...
