Let’s start our lesson on DNA with the simple elegance of the structure. The structure of DNA can be reduced to four parts. This model starts with the names A,B,C and D. There is no reason to insist on long words. A and B fit together in only one way. C and D only fit together in one way. But the AB stairstep has two orientations within the ladder and the CD stairstep has two orientations within the ladder. A given place in the ladder has four possibilities. That is all. The kids will be able

The elegance of DNA is in its simplicity. There is no reason why a model of DNA cannot be just the two base pairs. And there is no reason why this could not be given to fourth graders. This is a color, cut and paste activity and will result in a better image of DNA structure than the more complex models. Dear elementary school teachers: Please trust me. This will work with your students! You do not need to know anything! I say, leave out the long words, leave out the biochemistry, leave all that

Fifteen minutes of preparation would be plenty and the students will be busy for days and days: Open the zipped folder. Make copies of “make copies of this pdf” ; one copy per student. Color copies are good, but black and white will be fine. You need lots of scissors and lots of glue sticks. Put the video “first video cut and paste”and project it onto the screen The kids will be busy for the first day with this simple introduction.The download is a zipped folder. It contains: “print me now” dir

Density is a wonderful exercise in physical science and applied math. The students should repeat this over and over in various forms year after year. A big part of applied math is tracking the units. The answer sheets are carefully constructed to include all units and the teacher can use the answer sheets for the class without any preparation or even knowledge. This download includes an exercise, a carefully constructed answer sheet and the four thumbnails. This could be handed out to

The core of this lesson plan is; EXERCISE You are on the moon. It is a work sheet, but best used a guided classroom activity. This is a very new idea, “you are on the moon” and few classrooms could just tackle this. But the material can be introduced in a very visual way and the students will respond. This includes 8 documents • EXERCISE You are on the moon • ANSWERS You are on the moon .. the teacher could base the lecture on this • PRINT ME RIGHT NOW • The slides for the thumbna

Free radicals? What are they? Where do they come from? And what can we learn about chemistry through an exploration of free radicals?

Stoichiometry involves three different areas of cognition: Abstract thought, organized thinking and some skill in math. This exercise is much like stoichiometry, but the abstract aspect is missing. This makes it easier and will give the students encouragement when they get to stoichiometry. A big part of applied math is tracking the units. The answer sheets are carefully constructed to include all units and the teacher can use the answer sheets for the class without any preparation or eve
