In this lesson students will work with concrete. Students will be learning the effects of proper mixture and temperature.
Students will have a hands on project and work in groups of 4.
Students (each group) should carefully keep a journal of the mixtures, ie. the amount in % and weight of the mix and amount of water added.
Students will keep in the journal the temperature when the slump test is performed. The results should be compared with each group.
Note: Have everyone make a different mix. Some should have too much water so the concrete "slumps" during the test so students can see it's important to see what NOT TO DO!
