In this unit students learn how to measure temperature in an objective way. 
							 
							 Activity I. Hot! Cold! Warm!
							    
In this unit students learn how to make and interpret temperature graphs. 
							 
							 Activity II. Graphing temperature
							    
In this unit students learn how to warm things up and discover the differences between heat sources and heat insulators. 
							 
							 Activity III. Keeping warm
							    
In this unit students mix cold and hot water and make predictions and measurements of the resulting temperature of the mixtures. 
							 
							 Activity IV. Getting the right temperature
							    
In this unit students record the temperature during a process of cooling. 
							 
							 Activity V. Cooling down
							    
In this unit students investigate in which ways the heat can be transferred and how to cool things faster. 
							 
							 Activity VI. How to cool faster
							    
In this unit students are introduced to the concept of melting. They find the melting temperature of ice and observe the change of this temperature after adding salt. 
							 
							 Activity VII. Melting
							    
In this unit students learn the concept of heat absorption. 
							 
							 Activity VIII. Getting warmer
							    
In this unit students measure the temperature change during a chemical reaction of vinegar and baking soda. 
							 
							 Activity IX. A Chemical reaction
