This activity is a great way to either teach or review the different tools available for scientists to use in order to calculate mass, volume, time, length or look at objects closer. Students will cut out and glue together 6 envelopes to keep their task cards in. They will then label them (Mass, Temperature, Length, Volume, Time and Optical) and glue the unit of measurement on the correct envelope. From there, students will have task cards with a description and a picture of each tool that they will need to match with the tool’s name. Once the name is glued to the back of the card, the tool will need to be sorted into the correct envelope.
I have found these cards to also to be helpful as a way to review the tools. Students can hold up either side of the card to a partner, and the partner will have to give the name or what it is used for, depending on which side they are being shown. I used these with my 5th grade students and they were a really nice visual for my students to be able to identify different tools and learn how they were used.
