Kids LOVE a contest. This is a high action lab that gives first hand experience, builds a great vocabulary base, and connects several academic concepts. This is one of my students' favorite labs.
You will print the lab booklet (it will fit perfectly into a composition book). You will have to gather the tools and the mixtures substances. Change the set up of your classroom for excitement. Have two tables or desk sets at the front or middle of the room as competition tables. Make sure the AUDIENCE has a good view of the action. In an hour, I am able to teach the tools, give some background, and let all of my students have a turn at competing.
Play the Minute To Win It THEME SONG. Teach the tools. Discuss how each tool would use a physical property to separate a mixture. I have students take notes around the pictures. Read about how separation is used on Real Life.
This is how it goes:
Set up two competing tables at the front or center of the class. Set tools out for each team. You will ask two teams of two to compete. The rest of your class is the audience.
Give the two teams a mixtures (use mixture cards or make your own). Let them discuss HOW they will separate the mixture then begin the competition. The only rule is that NO HANDS are allowed… just tools.
Audience takes notes!! They keep track of the MIXTURE, the TOOLS used, and the PHYSICAL PROPERTY.
Your students will love this exciting lab and will remember how physical properties can be used to separate mixtures! After this lab, you students will KNOW THEIR STUFF. There is so much vocabulary that is learned by DOING and getting EXCITED about their activity.
