Your students are going to love this lesson on chemical reactions. This lesson is easy to follow and fun to use and teach with. These no fuss low prep hands on activities are going to have your students oohing and aahing.
This lesson has been designed to align with the NGSS standard 5-PS4-1 “ conduct an investigation to determine whether the mixing of two or more substances results in new substances”.
Included in this pack are:
What I Know About Physical and Chemical Changes – this activity is to see what their existing knowledge of physical and chemical changes is and what they want to know. I’ve included a panel of hints and given an example of each to help them get started.
Physical and Chemical Changes Reading Comprehension – students read about the differences between common everyday physical and chemical changes and the clues that scientists look for to see if a chemical reaction has taken place. They will answer questions based on the passage.
Chemical Reactions – Make A Lava Lamp – this is a fun activity the students will remember. In this experiment they’re going to make their own lava lamps powered by a simple everyday chemical reaction – effervescent tablets. It’s a great way to show them that some chemical reactions produce a fizz.
Chemical Reactions – Change of Color
This a really simple hands on experiment they’re going to love! They will make their own red cabbage indicator (no boiling required) and test simple household substances to see if they’re acidic, basic or neutral. They’re also going to see what happens when you mix an acid and a base together and the importance of a control.
