This is a fun and creative activity to tie all of the following concepts together into one lesson:DNA sequencing & transcription,mRNA translation,amino acid codons & proteins,genotype,phenotype,recessive & dominant alleles & traits.
Students will help solve a crime based on DNA evidence left on a lollipop at the crime scene.There are 3 versions of the same scenario that will identify 3 different criminals so you can use them for 3 classes – this avoids having the kids tell the next class who the suspect is ;).Each student will receive one of the 4 DNA samples – you can have students work individually,or have a group of students work on suspect 1,another on suspect 2,etc.(Sorry – I do not have an answer key to post)
I hope you are enjoying your summer!August will be a busy month as teachers prepare for a new school year.If you are a new teacher,or a veteran teacher,looking for new science lessons and ideas to add to your curriculum,my website is here to help.Everything I have posted is free for you to use in your classroom.All of my Google Slides can be edited to meet your needs –here is a quick tutorial to help you make modifications.
To help you find what you needquickly,there are several options available:
Search boxin the upper right corner – click on the magnifying glass and enter key words to find lessons.
Tag cloud– scroll down,on the right you can choose either a topic or standard.Each blog entry also has tags on them to help you find related lessons.
CategoryMenu– scroll down on the right and look for lessons related to your topic,such as ‘Life Science' or ‘Skills'
Enjoy the rest of your summer and best wishes for the 2018-19 school year!
I made these cheat sheets for my 7s to help them with our Meiosis and DNA unit.These are two of the most complex topics we cover in Life Science and it helps them synthesize all of the information into one page.
I use this activity as a guided review of reading metric measurements in cm and mm.Each student receives one metric measurement,you can laminate and hand out individual task cards to students,or simply print and cut apart so that students can write on each card as well.
As the measurement is projected on the board,the student with that task card will come up to the board and draw a line on the ruler for to represent that measurement,and add the value.Each student will mark the measurement on their own handout as well.Advance to the next slide,and a new student will add their value to the ruler.Continue until all students have added their values to the ruler,
This is a nice review sheet to practice identifyingQualitativeandQuantitiveobservations.Qualitative (think quality) are observations you can't really put a number on,while Quantitative (think quantity) are observations that are measurable or have a number value.In this exercise,I have the students alsounderlinethe word(s) that help them decide if the observation is Qualitative or Quantitative.
For fun,and to reviewInferences,I have the students infer what the dog is thinking as s/he listens to the human given directions
