Students are introduced to molecules, atoms, chemical notation, and chemical compounds through an engaging hands-on wet lab and LEGO brick models of atoms. Students will conduct a chemical reaction, compare physical and chemical changes, and then explore how matter is conserved during the reaction.
Students investigate photosynthesis by modeling where the atoms come from in this important process. Using LEGO bricks, students will build glucose molecules. Additionally there is a follow-up activity where the students can build both cellulose and starch from the same glucose molecules to demonstrate how glucose becomes incorporated into the roots, shoots and woods' structures of the plants we see around us.
This lesson looks at kite flying, a popular hobby in Malaysia, as a way to introduce basic ideas related to the dynamics of flight and can be used as an extension of a physics lesson, especially after the students have learned about forces. It will focus on some of the concepts such as weight, thrust, lift and drag.
In this video lesson, the student will be reminded that genes in a cell/tissue are expressed when certain conditions in the nucleus are met. Interestingly, the system utilized by the cell to ensure tissue specific gene expression is rather simple.
In this video lesson, students will learn what DNA fingerprinting is, what it is used for, and how it is used in paternity testing and forensics. Students will see how this technique actually works in lab. Students will learn how to analyze the gels used in this technique to match babies to parents and crime scene evidence to suspects.
The aim of this lesson is to introduce the concept of neutralization and its application in our daily lives. Students are encouraged to construct their knowledge of neutralization through brainstorming sessions, experiments, and mind mapping.
With an often unexpected outcome from a simple experiment, students can discover the factors that cause and influence thermohaline circulation in our oceans. In two 45 minute class periods, students complete activities where they observe the melting of ice cubes in saltwater and freshwater, using basic materials: clear plastic cups, ice cubes, water, salt, food coloring, and thermometers.
This lesson introduces students to the concepts of evolution, specifically the evolution of humans. The goal is to get students to link the concepts learned in their DNA, protein synthesis, and genetics units to their understanding of evolution.
